How to Add Freon to a Central Air Conditioning Unit

An air conditioner cannot cool your home without an adequate amount of Freon. So if you’ve noticed a drop off in the cooling power of your central air conditioning system, inadequate Freon levels may be the culprit. But before you try to add more Freon to your unit, there are several things you need to know.

Low Freon Means a Leak

The truth is that your central air conditioning system should never need to be “topped off” with Freon. The coolant in your unit is part of a closed loop system and doesn’t get used up like fuel. Instead it continues to circulate through your compressor, absorbing and releasing heat to keep the air passing through it cool and comfortable.

If the level of Freon inside your air conditioner drops below the proper level, it generally means there’s a leak somewhere in your system and you’ll need a qualified professional to find that leak and make the necessary repairs.

Professional Access and Expertise

Even if you’re inclined to add Freon to your unit, you’ll probably have a hard time getting your hands on it. As an EPA regulated substance, Freon can only be purchased by EPA certified technicians. If you’re able to purchase this type of coolant for your air conditioner, you’ll need to make sure you know what type your unit uses. Most air conditioners these days use either R22 or R-134a. It’s important that you only use the type of Freon that your air conditioner is built for.

Potential for Harm

Freon is regulated so strictly because it is an extremely hazardous substance. It can harm you or your family and it can do a lot of damage if accidentally released into the atmosphere. To top everything off, if you do accidentally release it, you could be subject to some hefty EPA fines.

In extreme cases, you can do irreparable damage to your air conditioning system by trying to add Freon inappropriately or without proper training. For all of these reasons, it’s best to let a certified professional check and, if necessary, top off the Freon levels in your AC system. For the minimal cost of this service, you can avoid risking the health and safety of your family as well as that of your AC system.
