• I have worked with Erasmo several times over the last few years for repairs as well as AC & furnace install. He has always been prompt, communication has been excellent, and his prices are fair. When we have had problems with our AC he has come out quickly to diagnose and then fixed the problem either the same day or within a reasonable timeframe.

• They’re great. I’ve used them multiple times. They may not be the cheapest, but in my experience, they’re the most knowledgeable.

  Eugene Z.★★★★★

• I asked CaliforniAir to install a dual zone mini split system. They were about to do it on time and discussed with me what they would do beforehand. I would do business with them again.

• Always delivers.

  Mario C.★★★★★

• From start to finish, the mini-split installation job was handled with the highest level of professionalism. The team showed up on time, communicated clearly throughout the process, and completed the work exactly on schedule. What stood out most was their attention to detail and the cleanliness of the job. All wiring and piping were neatly run through the foundation, leaving no exposed lines or clutter. Even helped with permit process at an agreed extra cost. The final result is not only highly functional but also clean and aesthetically pleasing.

• Today I was hosting my daughter’s 10th bday party, and of all days to have an issue, today was the day. 97 degrees and 18 people in the house!! 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!

• Exceptional Service & A/C Heating Mitsubishi Mini Split System received from CaliforniaAir! My family and I couldn't be more pleased with their system and professional friendly service. The Company Owner, Erasmo Alviar and his support team installed the system on time and at the fair price agreed, without any Surprises or interruptions to my family. I wouldn't hesitate to use CaliforniaAir Heating & AC again for my future needs and/or recommend them to my friends and relatives. Outstanding Service and AC & Heating System that Works Great!

• 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!

• 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 couldn’t 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!

• Awesome job and prompt response!

  Howard C.★★★★★

• Just awesome. After looking for a 24/7 emergency shop, Erasmo picked up at 3 am after our AC went out during a record heat wave. He was there in the morning, was speedy and professional, and made the repair at a very fair price. Truly a godsend.

  Justin G.★★★★★

• CaliforniAir delivers what they promised. I highly recommend their service.

  Frank C.★★★★★

• Good service by Erasmo. Answered our questions, inspected, and preformed our furnace annual service.

  Roger E.★★★★★

• Erasmo did great work at a good price repairing our AC. Cost us half what we were quoted by a bigger local company. He also gave us specific info about the condition of our AC unit, power draw, and so forth, which was super helpful. Will definitely call him up again if we need repair or install in the future.

  MJ C.★★★★★

• My A/C stopped working during the recent heatwave we had. I was fortunate enough to find a trustworthy company. CALIFORNIAIR HEATING AND AIR CONDITIONING. Erasmo came out the same day and diagnosed the problem in a timely fashion. He gave me an estimate that was very reasonable. Erasmo is prompt and professional. He completed the repairs in a timely fashion and is very thorough. I highly recommend CALIFORNIAIR HEATING AND AIR CONDITIONING! Thanks again Erasmo for a great job !!

• Erasmo made it easy for me to get a quote and install an air conditioner at my rental property in San Jose while I live in Arizona. His quote was far below a quote I had received from another company. He went to the property assessed my needs gave me 3 options. The airconditioner was ordered and installed in 2 days.

  Linda D.★★★★★

• Great experience with Erasmo and CaliforniaAir. I had a leaky AC condensation pan and water was everywhere. I had a different company out previously, and they could not find the issue, but they did want to sell me annual maintenance plan. Erasmo came over and quickly found the source of the issue, ordered the part and installed in on a Saturday. The price was fair and the service was great. I'll be sure to call CaliforniAir for any future issues.
