FAQ about HVAC'sGranbury HVAC Contractor, Glenn-Aire, Addresses FAQ’s About Heating and Cooling.

Listed below are several frequently asked questions regarding air conditioning systems.  Please take a moment to review the answers, and then contact us if you have any additional questions.

Please discuss why my indoor A/C coil/pipes/compressor has a build up of ice on top of it.

When your air conditioner has an indoor coil covered with ice, the ice build up typically signifies your air conditioner is either experiencing a low refrigerant level or has a clogged air filter. Whatever the case may be, your unit’s coil will become increasingly cool until the point during which the condensation will completely turn into ice.  An iced over coil can be devastating to the air conditioner’s health; ice is a common cause of bad compressors.

If you notice ice on your AC, first power down the system, and then inspect its air filter. Should the filter not be clogged, then the AC unit likely needs service.

Does my conditioner use freon? What about freon being “illegal?”

Current laws prohibit the use of R-22 in NEW systems after the year 2010. Also, legislation has set a cap on the production of R-22, and this will likely create increases in pricing as supply continues to tighten. However, R-22 will still be available for servicing your air conditioner for years to come.

What can I do to fix “hot spots” found within my home?

If you notice variations of temperature within your house, then you likely have duct work installed that is incorrectly sized.  The possibility exists that one of our many service technicians will be able to reconstruct the duct system in order to better improve airflow. Alternatively, we may be able to replace the windows within the hot room(s) with “Low-E” glass or perhaps have existing windows tinted. Window tinting should reduce sun load creating a cooler room while saving you energy at the same time.

My AC has a bad compressor. Do you recommend the system be repaired or replaced?

There are many reasons for which your compressor may have failed. One possibility is “burnout.” When burnout occurs, acid and burnt varnish are distributed throughout the system contaminating both the indoor and outdoor coils as well as the refrigerant piping.  Cleaning this oil can be a painful process.  Further, the oil can contaminate and shorten the lifespan of any newly installed compressor. When a burnout occurs, we suggest having the entire air conditioning system replaced.

However, if the compressor has failed because of a broken valve, a lightning strike, etc., then compressor replacement is a realistic option. When you arrive at this conclusion, then you  should consider the current age of the system so that you may better ascertain the value proposition.
