From beginning to end Tyler, Zach, and Noah were professional, respectful, courteous, and highly competent. They addressed all my questions and concerns. Tyler even helped me change a flat tire on my car ! We are very pleased with our new heating and air conditioning system as promised.
Performing emergency AC diagnostic service on 2009 Trane condenser. Discovered that the contactor failed and was not supplying 24v across, which prevents the system from starting up. Pressure switch on refrigerant line also failed. Ordering new part and was able to get the system temporarily up and running to keep our new certified members cool on this very hot summer day in Danville.
AC maintenance on a brand new installed by Certified Solar Heating and Air Conditioning, American Standard split unit system . Happy to report everything is work as designed and the Wallace’s should have a cool oasis out of the heat this summer.
Performing AC tune up on 1998 Bryant condenser and 1997 Bryant high efficiency furnace. Discovered that condition of system was hidden from new homeowners - someone painted over the rust to hide the poor condition of the furnace. Refrigerant is not balanced properly. Made recommendations for much needed repairs and went over replacement options.
No cool diagnostic ripped wire from under neath the house replaced ac up and running
Giving estimate to replace a 1989 Carrier system with a more efficient system using the PACE program (California First). Clients will be very happy with their new system and have peace of mind knowing that they will make it through the cold winters and brutally hot summers for many years to come!
Maybe time to replace pretty soon.
