CaliforniAir replaced an old furnace and installed a mixed system in our multi unit building (heat pump furnace and a single wall unit). They helped to retrofit a lot of oddities in an old building, and worked with us to make sure the project was completed exactly the way we wanted. They worked quickly and professionally, and I would work with them again

I did the thing, 4 separate quotes. This team is legitimately the best/fairest price around. I'll update this post with photos after the work is done!

Oh man, three hours ago I got quoted $5,600 from another vendor for AC repair. Erasmo came an hour ago. He said, “This price you got is crazy.” He diagnosed the issue in 5 minutes, went to his car, fixed one piece for $200, and left in less than 15 minutes. This is a whole new level of trust for me. He is forever my HVAC guy. So grateful he saved us $5,300 and a lot of unnecessary time.

Details: Repair • The power is on, but the fan won't run • Outside • House
