Diego Cardoso just left after performing a routine system check for us. He was great! Super friendly and efficient! He noticed our air scrubber wasn’t working properly and walked me through the necessary steps and cost to fix it in a way that made me feel comfortable saying yes on the spot. He completed the air scrubber fix and the system check and was out the door in little over an hour. I couldn’t be happier with the service today! What a great hire!

Diagnosing a 1979 Rheem furnace at Gursky Ranch in Brentwood, CA. The furnace was not getting power or gas, restored both and the system came on. Due to the age and condition of the furnace we went over replacement options even though I was able to get the old system to turn on. We look forward to working with you to get a more efficient system installed at this beautiful ranch home. Come check out their awesome general store! Thank you for choosing Certified Heating & Air Conditioning!

In Brentwood this Friday morning performing a furnace maintenance for the Niber residence. After today their home will have proper heating throughout the house. With a perfect zoning from upstairs to downstairs!

Furnace maintenance. Today we learned that our unit will over heat if we do not change the filters enough. Did you know that not changing your filter will actually shorten the lifespan and over heat your machine! Very important to change our heating and air conditioning filter! In the beautiful countryside of Brentwood ca! Thank you for having us.
