The New Refrigerant Circuit needs special care. Air conditioner installers have methods that need to be adhered to in order to keep moisture and debris from circulating through your new system. Proper removal of old refrigerants as well cleaning old lines with a special flush (unless they are to be replaced) will largely determine the life expectancy of your new system. Proper line brazing methods will ensure clean lines in addition to a filter dryer and deep line set vacuum. Compressor failure shortly after a poor installation is not uncommon.
Beware of the salesman who recommends a larger air conditioning system without a proper load calculation.
Many homeowners make the mistake of upsizing the capacity because the old system seemed to run all the time, when in reality it was probably not operating at its rated BTU’s because it was in need of a repair, or low freon or sometimes just old.
There are instances for upsizing, however they rare, and definitely require a proper load calculation to determine any size changes.
Oversized systems cause shorter run cycles which magnify any hot or cold spots that you already had. They also use more energy to run.
A properly sized system runs long enough to remove humidity properly as well as keeping an even temperature throughout the home.
If you’ve decided to replace your air conditioner, now is the time to upgrade with better choices for indoor air quality. Newer technology is available for air cleaners, whole house humidifiers as well as smart thermostats.
