A Question from Marlowe: Why Do Heat Pumps Need Refrigerant?

Despite its name, a heat pump is not designed solely for heating for Marlowe home. In fact, the technology in your heat pump was originally designed for air conditioning and is used today in air conditioners, refrigerators and cooling units in vehicles and airplanes. And the entire process relies on refrigerant – a chemical compound that is compressed and expanded to move energy from one environment to another.

How Refrigerant Makes Heating and Cooling Possible

Your heat pump has multiple components designed to transfer refrigerant from one state to another. The compressor, for example, compresses the refrigerant into a liquid. The liquid is then moved through the expansion valve to the evaporator coils where it expands into a gas. Because refrigerant evaporates at much lower temperatures than water, it does this rapidly and in the process draws heat from the surrounding environment.

That’s how an air conditioner or your refrigerator cool a space. However, in the case of a heat pump, the process can work in both directions. In cooling mode, your heat pump extracts heat from the air going into your home. In the case of heating mode, the heat pump extracts heat from the outside air. Because the heat is transferred into the refrigerant, it can then be recompressed by the compressor. The heat is then is then released in the condenser coils, where the gas returns to liquid state. A blower then distributes air blown across the condenser coils into your home as heat.

Troubleshooting the Process

A heat pump is a complex piece of machinery, but once you know how it works, you can perform quite a bit of troubleshooting should anything go wrong with the device. For example, if you notice cold air coming from your vents, you can check to make sure it isn’t in cooling mode and that there is enough refrigerant in the device.

Keep in mind that if any service needs to be performed on the heat pump involving refrigerant, you should call a Marlowe professional due to the volatile nature of the chemical. In most municipalities, you must have a license to distribute or dispose of refrigerant and even if not, it can be dangerous to both you and the environment.

Heat Pump Filter Care: A Guide from Mont Alto

On the whole, heat pumps are efficient, durable and effective in your Mont Alto home. They are built to run all year round without needing any more maintenance than your average furnace or air conditioning system and they have an average lifespan comparable to those other types of home comfort systems as well.

That’s not to say that there aren’t things you can do to keep your heat pump in good working order, however. Keeping up with the professional maintenance visits is an important step to take along these lines to be sure, but there are also some other things you can do on your own as well to help ensure the continued efficiency and health of your heat pump system.

Proper filter care is an important part of keeping your heat pump working the way it should. If you don’t have a heat pump yet but are thinking of getting one, make sure you have the installation technician show you where the filter is located and how to replace it.

If your system’s already been in place for some time, you can still find out how to care for the filter from your annual maintenance technician or you can probably even find it on your own by taking a close look at your heat pump. The filters are meant to be removed on a regular basis so they’re typically not hard to get to. However, you should always be sure that all of the power to your heat pump is turned off before you open it up to try and find, replace or clean the filter.

Most heat pump filters are meant to be changed or cleaned about once every 90 days or so. However, the specific requirements for each system can vary considerably, so you should be sure to find out what is recommended for the model of heat pump that you have.

Also, you’ll want to know what type of filter you have so that you can purchase the appropriate replacement. The model number for each filter should be clearly printed on it, so simply slide your current filter out and make note of the number so that you can purchase the correct type as a replacement.

Most heat pumps have replaceable filters, but some still do have permanent filters that are meant to be cleaned and then returned to service. If you have one of these types of filters, be sure to read the instructions for cleaning carefully before proceding.
