Performing a furnace repair!

Performing a diagnostic service on a 1996 furnace that was not coming on or heating the home in Clayton, CA. The furnace mysteriously began working as soon as I entered the attic and began heating the home. The client joked that it was the “Brittany Effect” and that I scared the furnace into working. The client became our newest maintenance member so we can continue making sure the system is working safely and efficiently! Thank you for choosing Certified Heating & Air Conditioning!

Diagnosing a zoning issue on a 2011 Carrier furnace in Clayton, CA in the Diablo Estates neighborhood. The upstairs zone is not coming on when calling for heat at the thermostat. Diagnosed failed wiring and will need to run a new thermostat wire for the zone to function. Luckily the clients still have heat from the other 2 zones in the home to keep warm. We will be running a new wire ASAP to get this fixed! Thank you for choosing Certified Heating & Air Conditioning!

Performing diagnostic service on drain line coming from the evaporator coil. System is leaking water behind the stucco where the drain line meets the concrete and enters the home’s drainage system. Discovered blockage in the line past the AC drain line. Made necessary repairs to ensure proper drainage and prevent further damage to stucco.

Performed tune up on 16 year old Trane AC. Client has $500 a month energy bills. System is extremely dirty and flooding water into the ductwork. Damage is too severe to this system, client looking to upgrade to a much more energy efficient system and zone not the ductwork.
