Berkeley is a city in Northern California on the east side of San Francisco Bay. It’s home to the University of California, Berkeley, birthplace of the 1960s Free Speech Movement. Berkeley has a warm-summer Mediterranean climate with warm, dry summers and cool, wet winters. The summers are cooler than a typical Mediterranean climate thanks to upwelling ocean currents along the California coast. These help produce cool and foggy nights and mornings.

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!

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.

Lindsay - Berkeley, CA 94703
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.
