"I’m so glad that I found Erasmo and team! They installed two heat pump units in my Duplex, gave me perfect guidance on the unit and the pricing. If you’re holding back to get HVAC because of complexity and or pricing, contact Erasmo, he’s going to give you an honest opinion and workable pricing. Erasmo was on time for the estimate and was very respectful. He..." Read more

"We've been fortunate to find a great heater contractor; Erasmo Alviar. We've actually had three heating units installed or replaced in our home over the past five years. Erasmo and the employees who work for him have been excellent at getting the job done right the first time and for a reasonable price. I'm really impressed by Erasmo's responsivene..." Read more

"We lost our insulation and ducting during a rain and water in the crawl space. Called a major company and realized after 9 days that the investigator and the company were not professional. Reviewed many companies and picked Californiair - it was based on their reputation and the company founder Erasamo is a hands on person with 18 plus years of experience. N..." Read more

"Erasmo is very reliable , he made to a point that the job will be done right , even had to triple check on the temperature after installation of the heating system. Brought a nice suggestion on brand as I asked for help because our old furnace stopped working okay. Thank you for that wonderful help and service."

"Erasmo came to the rescue during the latest heatwave. He answered promptly and came out the next day to find and fix the issue with my AC unit. Saved me from enduring 100+ heat outside. Many thanks!"

"Our AC broke in the middle of a heatwave, 110 outside. Called multiple people and nobody is able to come within 2 weeks! CaliforniAir picks up around 7:30 in the morning and fixed the issue before noon, fantastic response and we have working AC before scorching sun starts. Thank you!"

"When our A/C stopped working we had a different reputable company come out to try to fix it. They did their best but 2 days later and our A/C was still broken. Cali Heating & Air came out and was able to fix it quickly on their first try and for a very reasonable price! They are my new go-to for my air conditioning and heating needs."

He got back to me immediately and luckily had an opening the next morning. Erasmo worked with my tenant that evening to set up the appointment. He arrived on time. He..." Read more

"We had an issue with our Mini Split. There was a leak and the unit wasn’t blowing hot or cold air. Called Erasmo on Wednesday afternoon and he just so happened to be around the following day. He and his guys arrived on time and completed the service very quickly. They are definitely the only company I’ll be calling for HVAC needs from now on. Thank you so mu..." Read more

"Erasmo and his crew were a pleasure to work with! I got 3 quotes to replace our furnace and ALL of our ducts. CaliforniAir was $8K cheaper than the next best quote and they agreed to do a more complete job than the other company. The work was done on schedule and they cleaned up well. Erasmo made a house call a few weeks later to adjust our dampers and m..." Read more
