You might have heard of Freon (refrigerant) use in cooling appliances, but does a heat pump use Freon in the winter? Good question! What if I say Freon can opt for heat pumps during winter?

Yes, I am serious! Now that you are told the use of Freon in heat pumps during winter, it’s evident that there might be some function of the Freon use in heat pump working. Are you curious to know how? 

But wait! how come a coolant becomes useful in heat pumps? That is a tricky yet exciting matter, and users always seem astonished after getting through how Freon works on various appliances.

To know the use of Freon in a heat pump during winters or summers, we got you a detailed yet handy guide to enhance your knowledge, along with query-solving facts to make you correctly understand. 

Does A Heat Pump Use Freon in The Winter- Quick Fix

Heat Pump Use Freon In The Winter

Users mostly ask, “Does a heat pump use Freon in the winter” because Freon mainly refers to the refrigerant, and the first thing that comes to our mind seems to be cooling, but that’s not always the case.

Freon acts as an absorber and carrier, and heat pumps can transfer energy based on demand by use of a good absorber like Freon. With Freon, you can quickly cool or warm the house.

So yes, Freon adds warmth to the site when opting for a heat pump during winter. To know the mechanism behind it, check out the handy guide!

What Is Meant by Freon? Briefly explained!


Freon or Freon-22- a combination of these chlorofluorocarbons. A brand trademark with various halocarbon combinations and Hydrogen, chlorine, and bromine, along with chlorinated aliphatic compounds.

Freon is the name given to a combination of various aerosol fuels, organic solvents, refrigerants, and other chlorofluorocarbons that get obtained under a brand called Freon. Electronic appliances like AC, refrigerators, and heat pumps use Freon, causing cooling or warming based on the condition. 

The gaseous liquid seems nonflammable, less toxic, and stable that undergoes a process called evaporation to provide cool air, while the same opted-in coil, when heated up, causes the warm air to get supplied to the site. 

Is Freon Similar to Refrigerant? 

Usually, professionals might use Freon interchangeably with refrigerant. Still, Freon is considered a refrigerant brand that opts for many industries and commercial sites or in previously used appliances.

Still, its harmful components, including the halocarbons, cause detrimental effects on the Ozone Layer leading to its depletion. Keeping in mind, nowadays, Freon seems to get replaced with another refrigerant, a much safer and less ozone destructor than the Freon.

Will A Heat Pump Use Freon in The Winter? All You Need to Know!

Yes, a heat pump, like other electrical devices, including an air conditioner and refrigerator, also utilizes Freon as a refrigerant in the winter to carry out work and deliver the right amount of energy to the site. Freon acts as an absorber and carrier for transferring energy required for the predetermined area. To know the use of Freon, first, understand the heat pump described below!

Heat Pump and its Working

Those users who are unfamiliar with the heat pump might make this statement a great way to say that, yes, the refrigerant used as Freon in a heat pump works to either cold or warm the place. You are well familiar now with Freon so let’s see what a heat pump is, how it works and how refrigerant works in the mechanism involved in the heat pump. 

Heat pump 

A heat pump uses electrical energy and Freon to add warmth or cold to your site by acting dually. The pump mainly opts in countries like the USA, Canada, and worldwide throughout the year. The pump seems functional, with definite requirements based on the weather conditions.


  • Inner unit or evaporator unit
  • Outer unit or condenser unit
  • Refrigerant copper tubes connecting both units


The heat pump work in the following mechanism. 

  • In winter, most probably, the home interior temperature seems a little warm compared to the outside, so heat from the home to the outer environment dissipates to keep the natural balance as heat moves from high temperatures to lower ones.
  • The Heat pump works by interfering with the natural process that extracts the heat from the external source and adds to your interior, making it warm using pressure. The refrigerant (Freon) captures the heat and then passes it into the sink, which gets heated up.
  • The source is the outer environment, while the heating or delivering point is the sink. So this way, the home gets warm, eliminating heat dissipation. 
  • For cooling the room, energy absorption gets absorbed through the same Freon. And if the process gets reversed, the same refrigerant (Freon) would be causing cooling to the room by removing heat from the home (the source) to the sink to make the house cool, especially in summer. Freon as a refrigerant also works in refrigerators but as a coolant.
  • When used for cooling the surrounding, the Freon undergoes multiple evaporation processes, while the sum Freon, when opting for heating the surrounding with warm air, undergoes multiple condensation processes. 
  • The flow of refrigerant gets guided by the reverse valves depending upon both conditions. 

Will the Heat Pump Work When Low on Freon?

No heat pump won’t work when the unit is low on Freon because Freon is the primary energy absorber and carrier for transferring it to the site; without that, no energy seems absorbed. The beauty of Freon is that it cools the house in summer and is warm in summer, but with other parts, Freon seems nothing; the same applies to Freon. 

The Freon doesn’t get exhausted or finished; instead, it circulates and performs its function. The reason for its low levels always directs towards some facts that cause the low Freon levels. Among the most common refers to leakage. When Freon starts to get leaked, it slowly gets low, affecting the unit’s performance.

Users might find the heat pump low on Freon based on the heat pump’s efficiency and icing. Sometimes, the Freon might get leaked because of any fault or damage, leaving the unit down on refrigerant. 

The leakage usually occurs from the evaporator coil, condenser coil, or copper refrigerant lines. The lines seem to securely connect the evaporator line (indoor) and condenser coil (outdoor unit). So always maintain the refrigerant level to get efficient cooking and warmth, as the case may be.

To find a leak, the expert and professional use a pressure test method by using an electrical leakage sensor that clearly identifies the leak and then fixes it.

Can Freon (refrigerant) Cause Harm to Users? 

Despite the Freon ozone-damaging and destructive properties, it also affects global warming activities. That doesn’t seem to finish yet; the gas seems less toxic, but when in contact with humans causes severe issues. 

What if the gas gest accidentally reaches the lungs? Freon causes damage to the oxygen supply system with reduced oxygen to the body cells leading to a hypoxic state when inhaled. Freon may also cause severe skin problems; in case of accidental spillage, the skin can get damaged or sometimes harmed. It’s better to avoid getting directly in contact with the gas. Users working with these gases should always maintain safety measures with gloves and mask a necessary safety to opt-in such cases.

How Much a Standard Heat Pump Cost 

Heat pumps are costly devices but can help you reduce electricity usage and other billings once installed. Based on their installation, the device cost high.

for a standard quality regular-size heat pump, you would be costed around $8000 to $45000. the price may vary based on the installation site, unit brand, quality, working efficiency, and size.

02 types of Heat pumps are available, including air-water and ground-source heat pumps. The ground source seems more costly, reaching $45,000, while the air-water heat pump requires 7,000$ to 18000$ for installation.

Always consult a higher professional because the more experts you hire, the better would be your task will be done effortlessly. Don’t waste your cost on non-export professionals, or else you get poor installation, which adds more cost upon hiring a new expert. 


After going through the guide, the end conclusion would be your ability to answer Does a heat pump use Freon in the winter? We hope you got all the facts and knowledge necessary for investigating the use of Freon in heat pumps.

Having heat umps reduces the overall billing and cost spent on other systems separated opted for the different weather conditions.

The benefit seems many versatile and even large industries kept using the large heat pumps to maintain the inner surrounding temperature. Remember not to contact it directly as the gaseous liquid is harmful to humans to get inhaled and to the skin.
