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.

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.

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!
