Diagnosing a recently installed Day & Night furnace that was not functioning. There was a break in the low voltage wiring between the furnace and the thermostat caused by rodents. Repaired the wiring and restored the communication between the equipment and thermostat, system is now up and running and heating the home!

Performed a furnace repair in the Richmond area! The blower motor stopped working on our customer on the worst day of the season, one of the coldest. We ordered a new new blower motor, got out here ASAP and replaced. Our customer now has heat back in her home!

Working on a 2004 Carrier furnace in Richmond, CA. Client installed his own new thermostat and had to rewire the low voltage at the circuit board. After installation he had a major vibration coming from the system due to the metal on the furnace door rubbing against the metal of the junction box. I was able to secure the door in a position to make the vibration stop and the system is much quieter now. Thank you for choosing Certified Heating & Air Conditioning!!
