What is the Difference Between a Commercial Freezer and a Regular Freezer?

Are you looking to understand more about the difference between a commercial freezer and a regular freezer? If so, please read on. Residential refrigerators and freezers are smaller and more suited for household use. This is in contrast to commercial refrigerators and freezers, which are larger and more versatile. A household or residential freezer will be specifically designed to hold food for a family, whereas a commercial freezer will be able to hold food fit for a commercial operation such as a restaurant.

Is a Freezer a Good Investment?

Are you pondering whether or not a freezer will win out in a cost-benefit analysis? To that end, let’s explore some of the benefits. When you buy food, you want to keep it fresh as long as possible so that you can stretch times between when you need to go to the grocery store. Food keeps much longer in a freezer than in a refrigerator, which means that when you go shopping and put food in the freezer, it will keep fresher for weeks and months on end. Inevitably, this means that when food bargains arrive at your supermarket, you can buy more food and keep it stored fresher.

Many Americans have made the decisive choice to invest in a freezer for their home or property. Thus, if so many people are making this choice, it’s bound to benefit you as well, especially since you never know when there may be a crisis of some kind on the horizon.

How Long Does a Commercial Freezer Last?

Commercial freezer replacement will be necessary when your current freezer is old and experiencing sincere problems. These problems include failing to keep the proper temperature and freezer door disrepair. Nonetheless, it is important to understand how long commercial freezers last. If your commercial freezer takes a lot of wear and tear without maintenance, it won’t last as long as a well-kept commercial freezer. Commercial refrigerators should last at least ten years. With good upkeep and repairs, a high-quality model can last as long as fifteen to twenty years.

Does a Freezer Use a Lot of Electricity?

If you are worried that your new freezer will use a lot of electricity? If you weren’t already aware, the larger your freezer is will determine how much electricity it uses. For example, according to an internet user, their seven cubic foot chest freezer that is located in their garage uses an average of 1.1-kilowatt hours of electricity each day. During the winter, a kWh costs fifteen to eighteen cents depending on the time of day. During October through May, it can cost $4.68 per month. As a disclaimer, this is based on a 2017 estimate in an unspecified area of the country. More specific electricity cost measurements will depend on many extenuating factors that are related to your freezer unit and your area of the county.

What Temperature Commercial Freezer

If you want to have your commercial freezer operating at an optimal food storage temperature, then you will want to set your commercial freezer at or below zero degrees Fahrenheit. This will keep your food completely safe for consumption. This is possible due to the fact that bacteria will be prevented from growing at the frigid temperature. 

What’s a Commercial Freezer

Let’s get into what exactly a commercial freezer is. A simple definition of a commercial freezer includes the fact that commercial freezers are freezing machines used mainly by commercial business owners who are looking to freeze their products in order to increase the shelve life of their items.

Where to Buy Commercial Freezer

There are many different places for you to purchase commercial freezers. These locations include big box stores like Lowe’s and The Home Depot. You may want to shop around for the best price and product. Please be sure to consider shopping at more local stores in your area to support the economy in your town or city.

Do whole house humidifiers really work?

Humidifier in the home

Adding humidity to your air

Before we define what a whole house humidifier is and does it work, we’ll define exactly what a humidifier is first. A humidifier is an appliance that adds moisture into the air and prevents dryness usually associated with winter when houses are closed  up and for the winter with the heat on. 

For many people, that dryness irritates their lips, nose, skin, and throat. A humidifier is used for to ease cold and flu symptoms as well. It has been proven that a humidifier is good for asthma, and because a family member with asthma isn’t likely to spend all their time in one room of the house, a whole house humidifier is more beneficial to that person as well as the entire family and the home. 

Where a vaporizer provides warm, moisture in the air, a humidifier provides both cool and warm air in the form of vapor mist. This enables you to regulate the humidity that can make conditions worse for an asthmatic person. When using only a single portable humidifier, using a fan with the unit will circulate and spread the moisture air throughout the room. A whole house humidifier will do this through the HVAC system, spreading the treated air through the house, performing similar to a humidifier like a fan. 

What is the best humidifier for whole house?

As we described,, a humidifier adds moisture to the air, helping relieve the dry lips, skin, and throat that are common in the winter. For persons with asthma and other respiratory symptoms, a whole house humidifier can make a home more comfortable. There are many on the market, here, we list three of the most popular:

Are humidifiers bad for House?

For all the good that whole house humidifiers do, they also can cause problems, but when you know what those dangers are, you can take steps to minimize them.

  • Mold: A whole home humidifier is going to add moisture in the air through the ductwork.  That moisture its distributed throughout your house, condensing on the walls and windows. Just like the moisture from a plumbing leak, if the moisture is excessive, mold will grow and with that come health issues.  
  • Rot: Along with mold from excessive condensation comes rot when that moisture is left unattended. That rot on boards in the attic and basement will delaminate the floor and roof boards, cracks develop, the wood gets thicker, soft, and pulpy. 
  • Staining: That condensation on the windows will spread to the walls and stain. This isn’t a reason to forgo getting a whole house humidifier, but you need to take precautions to avoid this from happening. 

What can you do to avoid these problems?  Have your HVAC and whole house humidifier system professionally cleaned at the same time the air ducts are cleaned. During the winter, once every 30 days is recommended.

How Do Heat Pumps Work?

heat pump system

What is a heat pump? 

We have electric cars, solar panels, and windmills that generate electricity for our homes. More commercial structures are going with green roofing in a way to minimize the heat island urban effect. So, as we look for better ways to live our lives as comfortably but sustainably, more homeowners are contemplating a heat pump installation.

It is a newer system to cool and heat a home using the natural resource of the Earth’s heat. So, the name ‘heat pump’ is somewhat confusing. With a heat pump installation, your home will be cooled or heated from the never-ending supply of heat inside the Earth’s core. How? A heat pump doesn’t generate heat, instead it absorbs heat from inside the earth and  when it is in the heating mode, transfers that heat indoors.  

Likewise, a heat pump installation can provide your home with air conditioning too. When the heat pump system is in the cooling mode, it cools the air through an outdoor component and then send it indoors. In general, it is pumping the heat out of the Earth and transforming it as dictated by the thermostat setting. 

What is cheaper to run a heat pump or gas furnace?

The initial upfront cost and installation of a gas furnace is less expensive than a heat pump installation. Yet, if you are looking for a way to cool and heat your home, in addition to the furnace installation, you’ll still need to source a way to cool your home. 

With a heat pump installation, you’re getting both a way to cool and heat your home with one installation. When the utility bills come in each month afterward, you’ll see the savings that a heat pump installation provides.

With that being said, it is important to realize that your needs aren’t the same as your neighbor’s needs, nor is living in Maryland the same as living in Arizona. What we mean is that deciding the best method for cooling and heating your home, these two general recommendations can provide you some guidance in deciding if a heat pump installation is right for your home:

A heat pump, A mild climate: In areas where the winters are mild and temperatures average between 30 to 40 degrees Fahrenheit, a heat pump installation would be perfect. 

A cold climate, A furnace: In areas where the winter can be a bitter cold most days with below freezing temperatures, a furnace is the better choice because it doesn’t rely on the Earth’s temperature. When the ground is covered in snow for days, weeks, maybe a month or more, the Earth’s temperature isn’t going to be warm. 

Where should I place my heat pump? 

The location for a heat pump installation is key to the system working efficiently. It will keep the operating costs down, extend the lifespan of the heat pump and be less obtrusive to your neighbors. 

The outdoor unit of the heat pump is considerably more susceptible to the elements, just a like the outdoor component of an HVAC system. It isn’t anything that isn’t manageable to work with though. Things to take into consideration for the outdoor component of your heat pump installation is the climate, the local weather, and your immediate surroundings (busy city street, a bedroom community, or by the ocean). 

Factors that should be considered with an exterior component of a heat pump installation:  

  • Ventilation: For a heat pump to work efficiently, it needs an open area that gets fresh air constantly. It should not be installed in the attic, a closet, or the garage. It must have fresh air at all times and should not be any closer than three feet to a wall and no less than four inches above the ground. A concrete base is recommended that is a vibration-proof base. 
  • Maintenance: The outdoor unit of a heat pump installation should be placed where accessibility is easy for maintenance service. It should not be installed near any bushes, flowers, shrubs, trees, or any other large equipment. 
  • Surroundings: As mentioned above, keep plants and other growths away from the outdoor component of your heat pump installation, nothing closer than eighteen inches. Do not mow or weed eat next to the unit so that it doesn’t block the airflow. Avoid installing near dusty driveways and roads. Do not install close to bedroom windows (yours or your neighbors), a fence can be built around the unit as long as there is a three-foot space around the unit.
  • Weather: Do have your heat pump installation where it will be in direct sunlight. 
  • Sea Exposure: Coastal conditions, on the beach near an ocean or sea are vulnerable areas for heat pump installation. The salty air can cause frequent breakdowns from corrosion. There is coating available and your heat pump dealer can discuss that option with you. There is a ground-source style heat pump as well. 

The indoor unit of a heat pump installation is important as well. There are three options for the indoor component. Which is best depends on the layout of your home and your needs. 

  • The wall-mount is the most common with the ductless mini-splits. This style of mounting provides superb coverage with moving air efficiently, but it does take a considerable amount of space. 
  • The ceiling-mounted type of heat pump installation is typically found in hallways and provide great coverage with the air going in multiple directions but at lower airflow. Ceiling-mounted heat pump installation takes longer than a wall-mounted option. 
  • The floor-mounted heat pump installation is not popular and takes longer than the ceiling-mounted option. They are more expensive for installing, but if the ceiling and wall space is limited, it is an option. 

Is it worth installing a heat pump? 

A heat pump installation will be a system equivalent to a same size air conditioner. A heat  pump won’t lose  any power when it is heater mode, and when it comes to cooling your home, it provides  superior cooling. When a heat pump installation is replacing a 10 to 15 year old air conditioner, it will have less operating costs and cooler air in comparison. 

Electric heating wastes energy during  on winter nights that are short but chilly. A heat pump only uses electric power for transferring the heat, not creating it, and distributing it. With this process, a heat pump is up to four times more energy efficient over an electric furnace. 

What are the disadvantages of a heat pump?

As we have covered here, comparing a Heat pump vs central heating system, the heat pump has great benefits. Like anything though, a heat pump installation has some draw backs too: 

  • Upfront cost is high but has a long term ROI and reduces the footprint of carbon emissions.
  • Install is difficult, starting with required research of heat movement, local geology, and meeting specific cooling and heating requirements for your home. 
  • Sustainability is still concerning because of environmental impact of the fluids used for heat transfer.
  • Heat pump installation requires a significant amount of work and can be disruptive to your home and garden. 
  • Cold weather is not friendly on heat pumps. Because a heat pump requires electricity, it isn’t 100% carbon neutral, but they are compatible with solar application.

Do home air purifiers really work?

home air purifier cleansing the air

Quality Products for Easy Living

Do you ever step outside for a breath of fresh air when you’re at home? Only to realize the air outside was fresher than the air in your home. Studies have found that the air inside our homes isn’t as healthy as we would like to believe. Which explains the increase in home air purifier sales!

Today, we fill our homes with furniture that has glue holding it together. We need a home air purifier for dust and other airborne allergens like bacteria, mold spores, pet dander, pet odors, and viruses. With times as they are now, with COVID-19, a homeowner should take every precaution possible to protect their family, and a home air purifier can help.

Where should I place my air purifier?

Single-room home air purifiers are portable and can be placed in any room where you spend most of your time.  With this portability, you can get the maximum benefits. You should position the unit three feet from furniture or walls so the air can circulate properly.

home air purifier

How long does it take an air purifier to clean a room?

Depending on the size of a room, most home air purifiers will clean a small room with thirty minutes and a larger room within two hours. The room size is a factor in how long it will take, as is the fan speed, and the purifying coverage of the home air purifier your purchase.

The box of the home air purifier you purchase should have the information on it. If you’re purchasing your home air purifier in a store, a salesperson could inform you, or you research the different brands and models of home air purifiers.

You want to choose a home air purifier that will fulfill the size of the room you intend to place it. If you choose a four speed unit, it can get the air cleaner faster than a two speed home air purifier.

To get the best out of the air purifier, we recommend running the unit at full speed for at least a couple of hours and switch back to lower speed to maintain the room quality standard.

“Do you leave air purifier on all day?” and “Should I sleep with air purifier on?” are two of the most commonly asked questions when a homeowner is shopping for a home air purifier. These are legitimate questions, and the answer is simple: a home air purifier should be left on 24/7/365.  Why?

Because airborne particles such as bacteria, dust, and pet dander do not stop while you sleep, nor do they take the day off. If you turn off the home air purifier, it has to start all over when you turn it back on. To keep the air clean in the room where you position the unit, leave the unit on.

If the energy useconcerns you, purchase a four speed home air purifier and turn it down to the lowest speed during the day. What may surprise you, a home air purifier uses no more energy than your home computer. If you want to turn something off to save on energy costs, turn your computer off.

Are air purifiers a waste of money?

No, a home air purifier is not a waste of money. If you spend money purchasing over-the-counter medications, doctor appointments, and prescription medication for allergies, breathing issues, or sinus infections, a home air purifier can minimize these expenses, maybe eliminate them.You can expect severalhome air purifier benefits like these:

1.    A home air purifier will ensure clean breathing air inside your home for your family. It is estimated by the EPA that the air in our homes is up to five times dirtier than the air outdoor.

2.    A home air purifier will remove odors like the fish you cooked on Sunday, the cat litter box, and even the popcorn your kids burned.

3.    Your pets release airborne allergens from their fur and pet dander and let’s not forget the odors pets generate! A home air purifier will help you combat these things by removing them before they settle and become trapped.

4.    Whether it is your husband’s cigars or the fireplace, a home air purifier will help neutralize that smoke odor before it settles in the drapes and furniture.

5.    A home air purifier will trap dust that finds its way into your home.

6.    Home air purifiers remove as much as ninety-nine percent of the airborne bacteria that is in your home. During cold and flu season, and in times like we’re living today with COVID 19, a home air purifier will cycle the air through internal filters repeatedly to remove those things.

7.    Nothing is a better friend in your home during allergy, cold, and flu season than a home air purifier. A true HEPA air purifier that uses UV bulbs will capture those airborne germs and neutralize them.

home air purifier

Closing Thoughts

A home air purifier and humidifier will serve two different purposes. While the home air purifier will reduce the allergens like dust, mold spores, and pet dander, the humidifier will keep the air moist, making any allergy or asthma symptoms less irritating.

There are several models of home air purifiers on the market. There are brands with a replaceable filter and there is a home air purifier with washable filters. The choice is yours, each claim to be better than others, but do your research before purchasing one to get what is right for you.

What is Electric Heating in a Home?

Outdoor HVAC unit

Learn More About Electric Heating

There are many ways and methods of heating your home yet ones that have become more popular lately could be with radiant electric heating and other kinds of electric options. Essentially you can use the electrical systems you already use with your property and function it to where it will heat your home as well. With the many innovations seen with energy efficiency, this can indeed be a cost-effective way to heat your residence. It’s important to consider the details involved with each type of electric heating so that you can choose a heating option that will fit with your preferences. Get in touch with your local HVAC company today to discuss what can be beneficial for you. Here is some general information regarding electric heating that may prove useful in the meantime.

What does electric heating mean?

Electric heating has to do with a process of using electrical energy or currents that are then converted into heat energy. Common electric heating methods use water heating, space heating, and industrial processes. 

Electric Heating for Home

Electric heating can be applied to your home in several ways. You can use radiant heating in your floor, walls, and ceilings which can be enjoyable as they are quick options to heat a room. Here heat is applied directly to where it is placed through contact similar to stovetop heating where the surface is being heated and whatever comes in contact with that surface will be heated as well. A similar option to this is with hot water heating, aka hydronic, radiant floors often used in Asian countries. Another way you can use electric heating is with standard heat pumps which will take heat from the outside air using refrigerant and electricity to pump air into the property. You can either use compression heat pumps that run on electricity or absorption heat pumps that run on either electricity of combustion fuels like natural gas. Finally, electric furnaces can be used that work by using electric resistance heat coils to send heat through ductwork. As this is a forced-air system it’s important to regularly change air filters when needed.

Is electric heat efficient?

Electric heating is an efficient option in that it will use the energy used thoroughly to spread heat through rooms quicker than standard baseboards. 

What is the most efficient form of electric heat?

Infrared heating can potentially be the most efficient heating system as unlike other forms of electric heating, this system will warm the object and people directly instead of heating the air. This type of heating differs from convection heating systems used with central air systems and can be considered a more direct and instant approach to heating rooms.

How Electric Heating Elements Work

Electric heating will typically use a ribbon (corrugated or straight,) coil or strip of wire that will release heat about the same way as lamp filaments. The electric current will convert its energy passing through into heat which will radiate in all directions. This process is considered Joule heating where the current through the element will encounter resistance and therefore result in heating the element.

Why is electric heating preferred over other types of heating?

Electric heating may be an economical option over other conventional heating methods which can be why they may be preferred. Installation costs and running the systems can be moderate and there can be automatic protection against abnormal behaviors with electric heating.

What are the advantages of electric heating?

Electric heating is an environmentally friendly option as it won’t rely on burning gas and subsequently sending carbon monoxide through the air which would be released into the atmosphere. Using electricity will preserve natural resources since fuel won’t be required and therefore emissions won’t be released. You won’t have to worry about emergencies with gas as it won’t risk gas leaks.

Is electric heating the future?

Electric heating can very well be used more often as energy-saving trust reports state that post-2020 dwellings with direct-acting electric heating can achieve similar CO2 emissions than those with A rated gas boilers. This is in part due to the decarbonization of grid electricity.

What is the Average Cost of a Furnace Repair?

What can cause a furnace to stop working?

Were you searching the internet for “best furnace repair near me” and came across our website and this article? While this may not be the answer you wanted for “furnace repair near my location”, we believe we have some answers to commonly asked questions that may help you. Please keep reading and even if it doesn’t help you right now with your furnace repair needs, maybe it will at a later date. We will start with the biggest question:

Dirty filters clog a furnace fast and can cause it to shut off and stop working. Many furnace repairs calls could have been avoided if the air filter was replaced or cleaned regularly. Why? The furnace needs air to flow through the filter freely so it can blow over the heat exchanger and into the vents to each room in your home.

When the filter is filled with debris, dirt, and dust, the air can’t flow through it. They design furnaces today to shut off when things like airflow aren’t right so that the furnace doesn’t overheat and catch on fire.

How do you fix a furnace?

We will provide some simple steps that any homeowner can do or should learn to do if they don’t know how yet. These steps could keep you from making a phone call to a furnace repair technician and save you some money and keep your home warm without interruption.

  • The Thermostat: Make sure the thermostat setting is on “heat”, and if there isn’t any heat coming out of the vents, replace the battery. Then check the setting on the thermostat and compare it to the room temperature. Move the thermostat up 5 degrees and see if the furnace turns on. If you have a programmable thermostat, make sure it is on the right day and time.  If there is still no heat, trace the wires from the thermostat to the furnace for any breaks. If you find one, splice it together and tape it up. Using a hairdryer on cool, blow out the thermostat to remove debris and dust, then replace it, making sure you attach it firmly and level.
  • Breakers & Shut Off Switches: This may sound impossible, but many furnace repair calls have the result the technician finds is the furnace wasn’t turned on to start with. Your furnace may have a wall switch close to or on the furnace. Check the circuit breaker for the furnace and make sure the blower motor’s front panel is securely closed and fastened. 
  • The Filter: As we mentioned earlier, a clogged filter can cause a furnace shutting off. Either replace it or clean it, depending on which type of filter you have. This is one of the simplest problems that most furnace repair calls end up being.
  • Blocked or Leaking ducts: Check all the ducts for blockage and clear the blockage out. Check for leaks and mend those leaks with cloth duct tape.
  • Gas and Pilot Light: If your furnace is gas-operated, make sure you turn the gas valve to the on position, and the furnace is getting gas. If all seems in place, then check the pilot light and if it has gone out, re-light it. This can save you money on an unnecessary gas furnace repair call.
  • The Exhaust Flue: Birds and other critters will nest in the chimney exhaust flue because of the warmth. If you find a next in there, with the furnace off and thermostat down as far as it goes, take the duct apart and remove any blockage. Then reassemble it, learning how to repair furnace vent pipe with vent tape available at any big box home improvement store or hardware store.
  • Check and Flush Drains: One day of heat can add gallons of water to a high-efficiency furnace. When the drain lines become clogged with mold and sediment, it can cause the furnace to shut off – again, a safety feature. Remove the drain hose and clean it with bleach and water mixture in a 25:75 ratio and flush it out with clear water afterward.
  • Heat Pump, Exhaust, Intake Vents: If you find something blocking the exhaust or intake, clean it off. If there is ice on the pipes causing the clog, call a furnace repair technician.  This is more than an inexperienced homeowner can repair. If your home has a heat pump, make sure there isn’t any grass and/or leaves covering the outdoor unit.

How do I know if my furnace motor is bad?

They build furnaces hardy and sound, meant to withstand the dealings of winter. They typically require little maintenance or repair, but inevitably, they all will fail at some point. Many furnace repair calls find that the furnace motor has overheated, which may or may not mean it has gone out. Some of those clear signs it is overheating are:

  • A burning or hot smell coming out of the vents. This is sometimes accompanied by the furnace has shut off and if it hasn’t it will.
  • Loud unusual noises like humming coming from the furnace. The motor may be overheated, but it may still have enough power to start but it can’t turn. It generates excessive heat from the frozen motor, and it hums.
  • The furnace has cycled off and won’t restart without pushing the reset button. This is a sign that it is shutting off as safety, and usually, the motor has overheated.

How much does it cost to replace a furnace motor?

Nationwide, replacing the blower motor in a furnace can cost $400 to $600, this is labor and parts. The cost of a single-speed blower motor is around $450 along, while a variable speed blower motor can cost upward of $600 or more.

How does a walk in cooler work?

When you have a walk in cooler in your restaurant or similar business, you have a sophisticated piece of equipment. Knowing how it works will help you recognize problems when you need walk in cooler repair.

Walk in coolers operate similarly to your HVAC system, and have many of the same parts such as compressors and condensers. One of the most important parts of your walk in cooler is the evaporator, because it freezes the moist air to manage heat transfer. If your evaporator coils are icing up, and not defrosting, you may have a problem with the system. 

Condensers remove heat from the cooler in a similar way they remove heat in an air conditioner. In this case, however, the condenser regulates temperatures to keep your frozen and perishable products at the right temperature. If dirt builds up on the coils or the fan gets damaged, you could have problems with your condenser. The compressor adds pressure to the refrigerant and compresses it into a gas so it can flow back into the condenser. Drops in temperature may indicate your compressor is malfunctioning.

Anytime you see problems like drops in temperature in your walk in cooler, count on the team at Rocky HVAC for walk in cooler repair in Severn and Baltimore, MD. Find out how we can help or schedule our services, give us a call at (410) 216-0077.

Gearing Up for Fall and Winter

As the weather starts to cool down, it’s tempting to start cranking the heat up as high as it will possibly go. Doing that, however, can result in significantly higher energy bills than you may want to pay. Is there a way to have warm air without the steep costs? There actually is! If you are interested in a better way to heat, or cool, your home that won’t also involve a high price tag, take a look at heat pumps. This is a great investment that will provide full or additional heating to your home in the winter months.

What is a Heat Pump?

A heat pump is basically an all-in-one, heating, and air conditioning system. It works to essentially move warm air from one area to another. In the summer, the pump pulls heat from inside the home and transfers it outside of the house. Whereas in the winter, the pump will pull heat from outside the home and bring it in. If there is ever a lack of heat outside, there is usually an electric heater to supplement the heat so the air matches the thermostat settings.

At this point, you may be wondering, does a heat pump replace the furnace? While heat pumps are great for supplying heat efficiently, they ultimately do not produce as much heat as an oil, gas, or electric furnace. Because of that, it may be better to invest in a pump to supplement your heating and cooling system rather than replacing it. Depending on what size or type that you get, the heat pump cost can be relatively inexpensive. But how much does a heat pump installation cost? It can cost you a few hundred dollars or they could cost you a few thousand dollars. It ultimately depends on what size heat pump you decide on. You may feel inclined to attempt a heat pump installation DIY, but that’s often discouraged. Even for the most experienced technician, installation or replacement services can take up to 6-hours to complete. Instead, rely on the professional expertise of Rocky HVAC technicians. Since the pump is working with your ventilation system, it’s a good idea to invest in Air duct repair services as well. This will ensure that your whole system operates efficiently and effectively. 

Benefits of a Heat Pump Installation

Heat pumps may sound like a great idea, but what are you really getting with them? Are you really getting a good investment with benefits and advantages? We certainly think so! There are, in fact, a host of benefits to installing a heat pump in your home today. 

  • Hot and Cool: Despite the name, heat pumps offer heating and cooling solutions for homeowners. Rather than installing two separate systems, you can utilize just the one. In the summer, the system moves heat out of the home, while in the winter, the system moves heat in. 
  • Consistency: With a traditional HVAC system, you’ll often run into the problem of inconsistent temperatures. Some areas are cool, some are warm, and some you have no idea what’s going on. With a heat pump, that is virtually eliminated. 
  • Energy Efficiency: In general, heat pumps use less energy than a typical HVAC system. That’s because this device uses electricity solely for power, not for heat generation as well. 
  • Cost Savings: Since these pumps aren’t using as much energy, nor are they producing as much energy, you’ll notice significant savings over time. Your energy bills will start to lower and you’ll experience quite a bit of saving.

If you are interested in a heat pump for your property, give Rocky HVAC a call. We are the leading experts in your area for all things heating and cooling. Just like you’d hire an expert for aluminum siding installation services, hire the experts for a heat pump installation.

  • Do you really save money with a heat pump?
