Daniel was at my house within an hour and fixed my wall heater within a few minutes for an unbelievably cheap price. He also took the time to explain to me how to fix it in the future.

I recently had my furnace and air conditioner replaced, and I couldn't be happier with the service. From the start, communication was excellent; Daniel was incredibly responsive and answered all my questions quickly. The team arrived exactly on schedule and managed to finish the entire installation in a single day, just as promised. Their pricing was reasonable and honest, with no hidden fees or surprises at the end. Beyond their technical skills, the crew was very friendly and Daniel took the time to explain exactly how the new system works. They also did a great job cleaning up, leaving no debris behind. If you’re looking for a professional, tidy, and punctual contractor, I highly recommend them!

Working with Danny and Oleg is always a pleasure. They respond quickly, and take care of the problem in a very efficient and professional manner. I really appreciate these guys, and highly recommend CALIHVAC to everyone with HVAC needs.

CALIHVAC installed a 3 ton heat pump to replace our 60+ years old gas furnace. The installation went smooth and their pricing is very competitive. I will definitely recommend that you check them out if you're in the market for a heat pump
