Do Heat Pumps Use Freon? (All You Need to Know)

Heat pumps are one of the most popular comfort products around the world. They are used as a way of regulating the temperature of air and water of a particular area. Heat pumps are great at transferring heat between outdoor and indoor. 

Today, we are going to discuss whether heat pumps use freon or not.

Do heat pumps use freon?

Heat pumps are required to use freon refrigerants if they want to transfer hit between the outside and inside of the house. Heat pumps possess the unique ability to be both a cooling and heating system. Freon refrigerants are needed by heat pumps for optimum performance.

 Heat pumps need freon in order to function properly and accurately. They are used both as a cooling and heating system in households. Heat pumps need to use freon refrigerant to transfer heat between the outside and inside of your home. Freon is officially known as R22 refrigerant.

The R22 variant of freon refrigerant is no longer produced by freon refrigerant manufacturers. Instead, they are producing and supplying alternatives to this R22 variant. The R22 variant is intensely toxic to the environment and atmosphere. 

That is why there are many heat pumps available that use healthier alternatives to freon refrigerants.

Only the very old models of heat pumps actually have freon refrigerants inside them. The new heat pumps have alternatives of freon refrigerants installed inside them. 

Whatever the variant of the freon is, the most important thing here is the ability of that particular freon to transfer heat in different weather conditions.

It is necessary to make sure that the freon refrigerants of your heat pump are doing their job without any hindrance. A leak of refrigerant may cause a significant decrease in the performance of your heat pump.

Does the heat pump need freon to heat? Does the heat pump use freon in winter?

The heat pump has the ability to perform both as a cooling and heating system. Freon is a special kind of refrigerant that is found mainly in heat pumps. Heat pumps are depended on freon refrigerants to transfer heat

The heat pump does its primary job of transferring heat with the help of refrigerant.

The flow of refrigerant decides whether the heat is transferred outside or inside. In hot weather, the job of freon refrigerants is to absorb the heat from inside your home and transfer it outside. The heat pump can not heat your home in cold conditions without the flow of refrigerants.

The heat pump uses freon in winter as well. The freon refrigerants are responsible for absorbing heat from the outdoor and transferring that heat into your home. Without adequate freon refrigerants, the heat pump will fail to heat up your home in winter.

That is why the heat pump uses freon refrigerants in winter to warm your home in the best possible way. Freon refrigerant is needed by the need by the heat pump in both cold and hot weather. The heat pump will be of no use without freon refrigerants in it.

3 reasons why heat pumps use freon

There are several reasons why heat pumps use freon refrigerants to operate. Let’s discuss in detail some of them.

To warm up your home:

The heat pump gives away its function via its name. The primary job of a heat pump is to heat or warm up your home when it gets too cold. The heat pump brings warm air from outside into your home with the help of freon refrigerants.

Freon refrigerant is the key to absorbing heat from the outside and bringing it inside. That is a fascinating exchange of heat that happens between the outside and inside air.

To cool off your home:

The heat pump does not only heat up your home. It is also helpful when it comes to cooling off your home in excessively hot conditions. Some might argue that the heat pump is an excellent alternative to Air Conditioner (AC). 

The heat pump absorbs the warm air from inside your home with the help of freon refrigerants and later releases it outside. This brings down the temperature of the house significantly.

To function properly:

The heat pump is heavily dependent on freon refrigerants if it wants to function properly. The heat exchange that happens between inside and outside air is mainly due to the flow of freon refrigerants. Freon refrigerant is an integral part of the heat pump. 

The heat pump will fail to perform its core responsibility if there is no freon refrigerant inside it.

How often does heat pump need freon?

The freon refrigerants inside the heat pump stay good for up to ten to twelve years. They do not need to be recharged very often. The heat up must be checked regularly by a technician to find out if there is a leak of refrigerant in the heat pump. 

In that case, the heat pump will have to be repaired and recharged with freon refrigerants.

The heat pump needs to be refilled with freon refrigerants by a certified technician. The natural flow and amount of freon refrigerants are important for the heat pump to maintain its performance. 

The heat pump does not need refilling very often if there is no leak of refrigerants. The freon refrigerant usually has a life span close to the heat pump itself.

How to tell if your heat pump needs freon?

Your heat pump will show several symptoms and signs if it needs freon refrigerants. Let’s discuss in detail some of them.

A decrease in performance:

The heat pump transfers heat between the outside and inside of the home by utilizing the flow of freon refrigerants. If you notice a significant drop in the performance of the heat pump, it is a clear sign that your heat pump needs to be refilled with freon refrigerants. 

A heat pump in need of freon refrigerants will not be able to heat up your home in winter and keep it cool in summer properly.

An increase of noises:

If your heat pump starts leaking freon refrigerant, it will start making strange noises that sound similar to a gurgle. The refrigerator line will be filled with air instead of freon refrigerants when it has a leak in it. 

When you hear excessive noises coming from your heat pump, you should get it evaluated by a technician immediately.

Drops of refrigerant:

If your heat pump has a refrigerant leak, you will see several drops of freon refrigerants around the heat pump. This will indicate that your heat pump needs to fill with freon refrigerants immediately and the leak must be fixed.

Frozen evaporator:

A leaking heat pump will cause its evaporator to become frozen. This happens when the leaked freon refrigerants create thick layers of ice on the coil of the evaporator. This requires immediate attention and refilling of freon refrigerants.

Power consumption:

If your freon refrigerants develop a leak, it will increase the electricity bill of your household. If you see a significant change in power consumption of your electrical equipment, then you need to get your heat pump checked by an expert and refill the freon.

What type of freon is used in heat pumps?

There are different types of freon available that can be used in heat pumps. But all of them are not suited for heat pumps. Let’s talk about some varieties of freon refrigerants that work best in heat pumps.

Freon R407C:

Freon R407C is a wise choice when it comes to selecting suitable freon for heat pumps. The R407C freon type works best in small and medium heat pumps. These freon refrigerants are known for being used as both cooling and heating system.

Freon R410A:

Freon R410A refrigerant is quite similar to freon R407C refrigerant. This type of freon refrigerant is highly effective in heat pumps. It can certainly achieve a supercritical state when it hits above seventy degrees Celcius (C). 

Just like freon R407C, it works best in small and medium heat pumps.

Freon R134A:

Freon R134A is a highly efficient refrigerant. They are very good at exchanging heat between outdoor and indoor while using heat pumps. But the pressure created by Freon R134A refrigerant is quite low. 

This low pressure is responsible for increasing the expected investment cost.

Final Thoughts

Freon is used by heat pumps to regulate heat between indoor and outdoor layers of the home. Freon refrigerants help heat pumps exchange heat by absorbing it from one space and transferring it in the opposite space. Heat pumps keep the house warm in winter and cold in summer with the help of freon.
