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!

From the moment I met Erasmo and his team arrived at our home in the Santa Cruz Mountains, it was clear we were in the hands of professionals. Their friendly approach made the entire process feel like a breeze, and their thoroughness in every aspect of the installation was nothing short of impressive. What truly set CalifirniAir apart was their evident expertise. The team, led by Erasmo, quickly demonstrated a depth of knowledge that instilled a deep sense of trust from the get-go. They walked me through the process with ease, ensuring I understood and was comfortable with every step. Their efficiency and dedication to quality work was appreciated. Not once did I doubt their commitment to delivering the best possible outcome for our home. It’s rare to encounter a team that combines such warmth with unparalleled professionalism. I would not only recommend CaliforniAir for any HVAC needs but would also eagerly work with them again in a heartbeat. Their blend of expertise, customer care, and efficient service is a testament to the excellence small businesses can achieve. Thank you, Erasmo & your team, for making our home more comfortable and for leaving such a positive impression!
