I Couldn't Be Happier With the Service
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!

Reliably Installed a New Heater and A/C
Reliably installed a new heater and A/C unit. Had them visit several months earlier, and they didn't recommend work on another furnace we had.
I appreciated that honesty, and followed up with them months later when we needed our furnace and A/C replaced.

Excellent Service from Cali HVAC
We recently had Cali HVAC install a gas furnace and heat pump, and we are very satisfied with the entire process. Oleg was our main point of contact, and he was professional, responsive, and customer-focused throughout. Oleg, Tom, and team worked late hours to ensure the installation was completed on time and with good quality. Oleg also went above and beyond by installing the drip pan for the heat pump. Excellent service. Thank you, Oleg!
