Preventative Maintenance

       

    Dirty cooling coils        Dirty indoor fan motor           Dirty condenser coil

           It is a good idea to start thinking about pre-season cooling or heating services.  Just as we prepare our automobiles in the fall for the winter's freezing temperatures or the sumer heat, air conditioning and heating systems need to be prepared for these extreme conditions.  If you don't change the oil in your car it will lead to far more expensive repairs than that $21.95 oil change fee. 

     Even a film of residue on the coil and fins of the condenser will raise the high side pressure and decrease heat transfer to the point of increasing run time and decreasing compressor efficiency.

     In addition to the lost capacity, the compressor is consuming more power as it works against the higher pressures.  Just cleaning a dirty condenser can increase capacity by 20% or more while decreasing operating cost by 15% or more, depending upon how much the high side pressure is lowered.

Reduce the likelihood of system failure

     Properly servicing an air conditioning system will reduce the possibility of a problem during the summer and winter.  Just cleaning the ar condenser and lowering the high side pressure will decrease the stress on the system.  Additional items found during the pre-season check may eliminate other potential problems.  

     For example, vibrating copper lines, lines in contact with each other or in contact with the cabinet could become leaks.  Loose electrical conection and other problems could cause system or componet failure.
