Should I Add More Freon To My AC Unit?

Posted by Howell's Heating & Air on June 01, 2017

Is your air conditioning unit not cooling like it used to? Have you added Freon before and not sure if it makes sense to add more or consider a new system?

To start, it helps to learn more about Freon and what it means when Freon needs to be added to keep your home comfortable.

Freon is actually a trade name for refrigerants, and all air conditioners need refrigerants to work. Refrigerants, like Freon, are contained within the coils of the AC unit to cool and dehumidify indoor air. Freon is continually circulated around the system and doesn't just get low or need to be replaced at regular intervals. 

Programmable ThermostatThe only time Freon escapes is when there is a leak in your system. As the levels get lower there isn’t enough refrigerant to cool your home which can make you, and your family, uncomfortable and cranky.

If your system has a leak don't add more refrigerant without having a professional identify the source of the leak and determine where it is coming from. 

Cost of Freon

While less expensive than replacing your entire AC system, Freon isn't cheap. Most AC units hold 4 to 6 lbs of Freon, and depending on the type of refrigerant, a pound of Freon may cost between $65 - $85 and up to $150 per pound for R-22 which is being phased out as part of the Clean Air Act. So adding a few pounds of Freon without finding out why it is leaking can be a costly mistake.  Leaking refrigerants not only take a toll on your comfort and your wallet, but on the environment, so stopping the source of the leak is important. 

If your HVAC system is several years old and is leaking, or the leaks are getting worse, it is only a matter of time before the system will need to be replaced. When weighing the cost of adding Freon or replacing the entire unit, many homeowner’s decide the cost of Freon is worth it if they can get another year or two out of the system.
