2 Worth-It Things to Know about Your HVAC's Refrigerant


Do you have an HVAC maintenance agreement? If not, you could be stuck in a rut if you run out of refrigerant. If you’re like most homeowners, you only know the basics of this necessary part of cooling your home. Take a look at two worth-it things you should know about HVAC refrigerant:

#1: What Is Refrigerant?

The refrigerant in an air conditioning system is a liquid agent that cools and dehumidifies air. The coils of the air conditioning unit hold the refrigerant, and it works by absorbing the heat from the environment; it then turns from a low-pressure gas into a high-pressure liquid. A fan blows over the heated coils and that heat transfers outside. The refrigerant reacts by cooling and returning to a low-pressure gas and another fan blows air over the now-cool coils and sends it into your house.

#2: Do You Need a Recharge or a Replacement?

Whether you need a recharge or a replacement, it’s only safe for a trained and certified HVAC technician to handle refrigerant. You can tell you are ready for a recharge if the air blowing out through your vents is gradually getting warmer. It might not be noticeable at first, but your AC will show signs of not being able to keep your home at the temperature you set on the thermostat.

An HVAC technician will be able to tell you if you need replacement instead of a recharge. This would be due to a leak or damage to the unit. In either case, call a reliable HVAC company for service.

The good news is if you have a maintenance agreement in place, you don’t have to worry about recharging or replacing your refrigerant. A qualified technician will check the refrigerant at your annual spring maintenance visit, so you know you’ll be ready to go when the weather gets hot.
