Job Stories From Ontario, CA
Rusted Evaporative Cooler Ontario, CA

  Evaporative coolers offer a cost effective and eco-friendly way to cool your home especially in dry climates.  Unfortunately, with time and lack of maintenance things can go wrong. 

  AQS Heating and Air Conditioning was contacted to help a homeowner in the city of Ontario, CA. Our customer expressed his concern for an evaporative cooler leaking on the roof.  Senior technician Mark Ibarra identified the problem immediately, the damage was evident. Excessive rust and corrosion were found in the swamp cooler cabinet causing the leak. Due to the age and condition of the unit his recommendation was to replace it.

   A few days later our installation team started the replacement process by carefully removing the damaged unit. A new evaporative cooler was installed, electrical and platform were adjusted.  Our customer can now stay cool during the warm summer months.
