    4 ton Furnace and evap coil Replacement Menifee, CA


     A homeowner in the city of Menifee, CA was tired of experiencing the same issues with his furnace for the past 3 years. After several unsuccessful repairs by previous contractors the furnace has stopped working completely. 

       He requested the expert services of AQS Heating and Air Conditioning to locate the root of the problem and expressed his concerns with the previous repairs. Senior technician Mark Ybarra met with the homeowner to take a close look at the furnace. Upon a complete inspection he discovered a cracked heat exchanger. A furnace replacement was recommended due to the age and major component damage. 

       A few days later our installation team returned to install a 4 ton Lennox furnace and matching coil. Properly sealed the base with duct sealant and reinsulated plenum. An air scrubber was installed. The unit was charged to factory specs and the results speak for themselves. Our customer was really excited to finally have a working system during the winter.
