Friendly, high quality, efficient service!

Wyatt and Nick were fantastic! Super friendly, punctual and professional, they worked efficiently, answered all my questions, explained everything and showed how the new furnace worked. They took care with my floors and were even careful not to let my cat out! I would not hesitate to call them again for another job, though I hope I won’t need one!

Fabulous experience

Jackie Green was outstanding! She was professional, friendly, and got the job done well. She communicated the issue and options clearly and was able to complete the work the same day. This woman deserves a raise! 10/10 would use them again.

Amazing service! Honest and affordable price!

After having a quote from another company for $850 to fix my furnace I called Certified Heating & Air and got a second opinion. Tyler arrived soon after and fixed it for $69! The issue was not even what the first company said it was. HIGHLY RECOMMEND Certified Heating & Air and HIGHLY RECOMMEND TYLER! I will call this company when my furnace needs replacing.

I am in Berkeley, California to look at adding a split heat pump system to a older home converted into apartments. The layout of the home is unique, but with a custom designed system, we will be able to provide heating and cooling throughout the home.
