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!
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.

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.

Today was a perfect day for a blower wheel cleaning . It’s such a beautiful day in the city of Berkeley Ca right by the famous Grizzly Peak and Fish Ranch Road! There is just a ton of dust collecting inside of the furnace and ac and this unit is only about 2 years old! Take a look at the before and after! If only I could load more than two pictures so you can see the significance of the rest of the unit! Have a great day everyone!

Replacement furnace installation in Berkeley California

Just finished a heating maintenance on a 2008 high efficiency gas Amana Furnace. The unit itself is clean but there was some rusted water coming from heater parts that are not supposed to have water . So we did some digging deeper inside the belly of the furnace and came across a heat exchanger that is just torched almost all the way through. Checking out of Berkeley Ca.

Hello Berkeley Ca. Checking in for another air conditioning maintenance. This unit is only two years old and has already collected so much dust. This is sheet rock and remodeling material that has just invested the furnace. Poor thing needs to be cleaned and or upgrade the filter ! If you have been remodeling lately make sure it’s not in your airflow and clean breathing air! Thank you for having team certified!
