Freon is a commonly used refrigerant in air conditioning units, but there are several important things to know about it to ensure proper usage and maintenance. We’re Teko.ph, the largest aircon and appliance services provider in the Philippines, here with a quick guide on freon in aircon, how it works, and how often you should have it refilled.
What is Freon?
Freon is a brand name for a group of refrigerants that contain chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs.) It cycles through an air conditioning system, transferring heat as it changes from low-pressure gas to liquid. By drawing out the heat inside your home and pushing it outside, refrigerants allow you to enjoy cool temperatures indoors. You can typically find it within the AC’s coils for maximum efficiency in removing excessive heat from your space.
Freon in Aircon Today
Although it is important to cool our homes through air conditioning units, Freon and other CFC & HCFC refrigerants are environmentally harmful. They contribute to the depletion of the ozone layer, which protects the Earth from harmful UV radiation. As a result, these refrigerants’ production and use are already being phased out.
Today, most air conditioning systems in the Philippines use more environmentally friendly refrigerants such as hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs.) Usually, the Best Aircon Brands in the Philippines use newer and more eco-friendly refrigerants, which have a lower impact on the environment than older refrigerants.
What To Do With Freon in Old Aircon Units
It is possible to replace Freon with an alternative refrigerant in older models of air conditioning units. However, it is important to note that the replacement process can be complex. It may even require significant modifications to the system. Additionally, not all air conditioning units are compatible with alternative refrigerants. It is important to consult with a professional aircon technician before making any changes.
When to Refill Freon in Aircon
In general, an air conditioner should not require regular refilling of refrigerant if it is properly maintained. Just like aircon cleaning, aircon freon refill will depend on many factors, such as the type of unit, its size, and how often you use the aircon. Common signs that you may need freon refill for aircon include:
- Reduced Cooling: If your air conditioner is not providing sufficient cooling, it could be a sign of low refrigerant levels. The refrigerant plays a crucial role in the cooling process.
- Increased Electricity Bills: If your aircon consumes more electricity than usual, it may work harder than necessary to compensate for the low refrigerant levels.
- Hissing Sounds: This could be a sign of a refrigerant leak.
- Frozen Evaporator Coils: If the evaporator coils in your air conditioner are freezing, it could be a sign of low refrigerant levels. It may also be a sign that your aircon needs cleaning, so be sure to have it checked.
- Moisture or Ice Build-Up: This could indicate low refrigerant levels.
If you see the need to refill the Freon frequently, it may be a sign that something is wrong with the AC. Instead of wasting money and potentially damaging the aircon, call an aircon expert immediately to know its cause.
