Ultimate Guide to Furnace Repair

Do Heat Pumps Use A Lot Of Electricity?

Heat pumps work by moving heat, not air.

Electric heat pumps use much less energy than furnaces, and can cool houses too – here’s how they work:

Most heating systems in the U.S. use forced-air furnaces that run on natural gas or electricity, or in some cases heating oil. To heat the building, the systems burn fuel or use electricity to heat up air, and then blow the warm air through ducts into individual rooms.

A heat pump works more like a refrigerator, which extracts energy from the air inside the fridge and dumps that energy into the room, leaving the inside cooler. To heat a building, a heat pump extracts energy from outdoor air or from the ground and converts it to heat for the house.

Here’s how it works: Extremely cold fluid circulates through coils of tubing in the heat pump’s outdoor unit. That fluid absorbs energy in the form of heat from the surrounding air, which is warmer than the fluid. The fluid vaporizes and then circulates into a compressor. Compressing any gas heats it up, so this process generates heat. Then the vapor moves through coils of tubing in the indoor unit of the heat pump, heating the building.

In summer, the heat pump runs in reverse and takes energy from the room and moves that heat outdoors, even though it’s hotter outside – basically, functioning like a bigger version of a refrigerator.

What are the Components of a Heat Pump?

Different components make up a heat pump, and it is important to know all of them before you can understand how a heat pump works.

Major Components

The major components of a heat pump include.

Outdoor Unit

The outdoor unit is made up of a coil and fan that work together to kick starts the exchange of heat. The fan blows air on the coil, which can double as a condenser and an evaporator.

Indoor Unit

The indoor unit is also called the air handler unit. This unit also contains a fan and a coil, and the function requires the components to get the air moving across the ducts throughout the home.

Minor Components

There are multiple minor components of a heat pump. Here are some of them.


This substance absorbs the heat or rejects it when the heat circulates in the heat pump system.


The refrigerant needs a compressor that can pressure it to move along the system.

Reversing Valve

As the name suggests, this component reverses the refrigerant and helps the system switch between two options, heating and cooling.

Expansion Valve

The expansion valve regulates the refrigerant and reduces its pressure and temperature. This valve is also known as a metering device.

How Does A Heat Pump Work?

The heat pump works in two different modes. Each mode has a different function; here is how it works in both modes.

Cooling Mode

In the cooling mode, the liquid refrigerant makes use of the expansion device, which is located in the indoor coil and is pumped. The air that is inside the house gets blown on the coils, and the refrigerant absorbs all the heat energy. After the refrigerant absorbs the heat, it heats up and transforms into gas, and the gas goes into the compressor, which pressurizes it.

The gas gets heated and moves towards the coil located in the outdoor unit. This is where the fan moves the air from outside across the condenser coils (cooling mode). This allows the heat to transfer to the outside air, and the refrigerant converts back to liquid.

The refrigerant is then pumped to the expansion valve in the indoor unit.

The expansion valve reduces pressure from the warm liquid. Once the refrigerant is completely cool, it is again pumped into the indoor unit so that it can cycle again.

Heating Mode

Typically, the heating pump works similarly in the heating mode as it does in the cooling mode. However, in this mode, the flow of the refrigerant is reversed. When the refrigerant flow is reversed, the heating source is used as the outside air, and that heat energy comes from inside the house.

In this case, the outside coil is used as an evaporator, and the indoor coil is used as a condenser. Other than this, the rest of the process is the same, and the cycle goes on that heat up the entire place.

A heat pump is a magnificent device that can help with effective heating and cooling. Its versatility makes it a great option for many as you can use it to heat and cool a place.

How do You Maintain Heat Pumps?

Many people are inclined towards using heat pumps, but it is very important to know how one must ensure optimal functionality of heat pumps by maintaining them. If you are using the heat pump on a daily basis, then you must change the air filter at least once a month. If you do not use the heat pump that frequently, you can go on for months before you have to change the air filter.

In addition, you must also make sure that your device is as clean as possible. You must clean the fans and coils as they are most likely to gather dirt and other debris.

There are several different problems you can face with your heat pump. That includes duct issues, noises, and other concerns. This is why it is a better idea to address your heat pump concerns as soon as you can.

Your heat pumps require regular maintenance, and for that, you can reach out to an expert specializing in heating and cooling systems as they will be able to help you in the best way.

Make sure that you get timely help with your heat pump so that there is no additional damage. A good expert will be able to identify the issue and give you the best service to fix it.

Bottom Line

There are lots of experts out there who claim to be the best at what they do, but you need to be very cautious when asking for their help. Do your research and go for an expert who will provide you with guaranteed services.

Take your time to make a decision and get a quote from different experts so that you can choose the best one possible. Always go for a company that has experienced professionals and has good reviews from many customers.

These experts can help you with all your maintenance concerns regarding the heat pump and will also install them for you.
