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!

Erasmo did excellent job to fix my 40 years-old air-condition. He was responsive and professional. When an OEM part was not available, he managed to find a more generic alternatives. I am very impressed!

CaliforniAir workers was very informative of the work they provided. They also completed the project in two days instead of three. They made sure their work area was clean, during and after the project was done. I would definitely use them again.

Above and beyond. Showed up ½ through the promised window which was perfect. And then finished the project in less than an hour. He explained everything and was very kind and courteous. And their estimate was less than the others that responded to my request. Very satisfied customer!
