Erasmo was punctual, professional and knowledgeable about our heating system. He knew the brand (which I did not as no labels) Found the problem quickly and got it working again. I would highly recommend him Now I can’t wait for cold weather!

Great experience overall. Pricing was incredibly reasonable. They came very quickly and were able to install (including electrical work) in one day. They were clean and tidy throughout the job, no mess left behind. Definitely recommend!

Erasmo has done a decent job for my capacitor replacement. Though the final price went over my expected budget, it was a pleasure to hire him for his friendly manner and professional expertise. Highly recommend!

Erasmo is a pleasure to work with. He has always resolved the issue quickly and affordably. After negative experiences with other HVAC companies, I’m grateful to have found someone I trust. Can’t recommend him enough.

Working with Erasmo and his team was great. They did the job in a very quick and timeline manner, and to a high level of quality. We did one outdoor unit with two indoor mini split AC units. Highly recommend CaliforniAir.

Very clear about when he was coming, I was informed so I could plan around his visit. Very good and quick service

Thumbtack customerJun 2026

We had a good experience working with Californiair. They were professional and did a quality work. They came on the same day to give an estimate and within few days were able to accommodate installation. When accidentally their worker stepped on a Sheetrock, they sent a guy to fix the cracked Sheetrock.

Thumbtack customerJun 2026

He was clean and neat and honest . he fixed my ac for 300 and for the problem it had and didn’t try to oversell. Another company had come and given the wrong diagnosis so I can spend more money. This company is fabulous and I’ll use them in future .

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

Thumbtack customerFeb 2026

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!

AnaCena H.Oct 2025

I loved working with CaliforniAir Heating! He was super responsive, gave us a very reasonable quote and was able to install the heat pump within one day

Erica f.Sep 2025

Will continue to use this company for regular maintenence

Matthew S.Apr 2025

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!

Swati G.Oct 2024

Erasmo and his team were friendly, easy to work with and did a great job for a very reasonable rate. I would most definitely hire them again. Five stars for sure.
