HVAC : Highly Recommend CaliforniAir Heating & Air Conditioning!We worked with Erasmo, he is super professional.We recently had CaliforniAir Heating & Air Conditioning install a Mitsubishi heat pump system in our home, and we couldnt be happier with the results! From start to finish, the process was smooth, professional, and efficient.Expert Installation: They installed a Mitsubishi PVA-A42AA7 air handler & PUZ-A42NKA7 outdoor unit with precision. The team handled everything, from removing the old unit and capping off the gas line to designing the new system layout and relocating the indoor and outdoor units.High-Quality Ductwork: We also had a new duct system installed, including vent replacements and air balancing dampers, ensuring even heating and cooling throughout the house.Attention to Detail: They sealed and insulated all plenums, installed a new PVC drain system with a float switch, and made sure everything was up to Title 24 compliance.Electrical & Permits: They took care of the electrical wiring, permits, and HERS testing, making the entire process hassle-free.The crew was punctual, knowledgeable, and professional, answering all our questions and ensuring we understood how to operate the system. Plus, the 10-year warranty on parts and labor gives us peace of mind.If you're considering a heat pump installation or HVAC upgrade, I highly recommend CaliforniAir. They deliver top-notch service and quality workmanship!

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

I had Erasmo and his team move and replace my furnace along with all my ducting. They were very professional, knowledgeable, and affordable, and did a great job with my project. I am delighted, with the outcome and would recommend them unreservedly.
