help with HVAC Refrigerant Leaks


Leaks are bad. Some are more serious than others, but they’re all bad.

Leaks involving personal information, national security, or White House leaks – those can be devastating and have long-term consequences. Other leaks, like those involving motor oil, plumbing, roofing, a/c systems etc., are bad but are repairable.

Nevertheless, all leaks are bad.

So, let’s consider the problem of leaking refrigerant used in older model A/C systems.

Leaking refrigerant (also known as Freon) results in reduced efficiency for your A/C unit. If the leak is significant, your unit will freeze-up. One of techniques used by many HVAC companies over the years is to check Freon levels and top off if needed. Topping off basically replaces refrigerant which has leaked through small cracks in the coil. NOTE: topping off obviously does not work well for major leaks.

R-22 is an ozone-depleting chemical which harms the earth’s ozone layer. In 2009 the Environmental Protection Agency mandated that R-22 cooling refrigerant used in HVAC systems be phased out. No units containing R-22 could be made after 2010, and the use of R-22 was to effectively cease by 2020.

It has been available, until now. This week NASCAIR was informed by several distributors that they will no longer be stocking R-22 refrigerant.

What this means to you, the Charlotte homeowner, is this:

If you have an older air conditioning unit that uses R-22, and if you have been babying that system’s leaks —
it’s time to start looking at a new generation system replacement. 

The handwriting on the wall is clear to me. If it is for you and you want information on next generation, highly efficient, heating and cooling systems, contact me by phone at 803-802-8884 or email me – ddrew@nascair.com.

Thank You.
