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!

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

Their team was able to see us quickly and gave us 3 different quotes for our needs, but provided us options. Oleg was my primary contact and he was very helpful in answering all my questions and educating me on what was best for us and our home. We replaced our old furnace and ac with a new dual fuel heat pump and ac, which I knew nothing about until Oleg told me. I did my own research and found that this was a great choice for us. Their prices are great and we were able to get our replacement quickly. They worked efficiently, even assisting me with setting up the new thermostat on my phone. I appreciate their team and recommend them if you ever need any HVAC needs.
