How Often Does HVAC Need Freon

You’re probably relying on your central air conditioner to keep cool. How often should you recharge the refrigerant? Does it follow a fixed schedule or depend on the unit’s usage? This article will discuss the frequency of refrigerant recharges for your AC unit and the factors that impact it.

How often does a central AC unit need a refrigerant recharge?

Is it necessary to recharge your air conditioning unit for optimal performance?

No, you do not need to recharge your AC unit on a specific schedule. In most cases, units only require recharging every 2 to 5 years, sometimes even longer. The exception to this rule is if the system has a leak, causing the refrigerant levels to decrease over time. If your unit no longer cools as effectively as before or the compressor runs more frequently than usual, it could be a sign of a leak.

If your central A/C is running low on refrigerant, you may be tempted to recharge it yourself. However, this is not recommended for several reasons. Handling refrigerants without proper training is dangerous. The law states that only HVAC contractors and their certified technicians can sell refrigerants. Recharging with refrigerant is only a temporary fix since it will eventually leak out again, requiring more frequent recharging. Additionally, recharging with refrigerant can void your warranty. It’s best to contact a professional for service if your central A/C is running low on refrigerant.

What is refrigerant and how is it used?

Refrigerant, also known as coolant or evaporator fluid, is a substance used in air conditioning and refrigeration systems. Its purpose is to transfer heat from one place to another. In a central air conditioning system, the refrigerant absorbs heat from inside your home and transfers it outside. This process is what keeps your home cool and comfortable during hot summer days.

Freon is the most commonly used refrigerant in central air conditioning units. It is the brand name for a group of haloalkane gases used in air conditioners. These gases are highly efficient at transferring heat, making them ideal for air conditioning purposes.
