Great working with this team. Had a nice set of 3 mini splits and a heat pump installed. Will have their team back soon for an upgrade on my first floor as well. Recommend them!

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

SMH!After numerous calls, Erasmo was the only service available to see to my issue within an hour.He was timely, respectful , attentive with his work and very fair with his service costs.He solved my issue within minutes and had AC working beautifully.I highly recommend him and his company, they have integrity and are respectful. I will definitely utilize his company and its services again. Cheers Erasmo!

Erasmo and his team were excellent. Erasmo came out to assess our home for an HVAC system quickly after our request online. He seemed very competent and knowledgeable. Pricing was fair. His team was professional, punctual, and worked efficiently. They got our new system in much sooner than the estimated timeline. The new system works seamlessly and they left the site clean. I would not hesitate to recommend working with them. Thank you for everything!
