It was an excellent experience. My new heater was put in professionally, and it didn’t take too long. Service was excellent. Gary didn’t try to sell us something we didn’t need or take advantage of the situation like other people.. I found him to be trustworthy.
We have a new Mitsubishis heat pump installed recently at our home. The Freon Team is very knowledgeable and professional. They can adept and make adjustments to fit our needs. We are very happy to the service they provide.
The initial visit seemed to go well, the quote rep came out & seemed knowledgeable. But there was a bit of a disconnect between the sales rep (quote guy) and the installation team. They need to do a better job of communicating and establishing an install plan because sure enough the install guys came and had no idea what was going on & where to put things. The quote guy tried to blame me but really they should have been more thorough and provided those details to their own team. I’m not their project manager, so it seemed unprofessional and I almost cancelled the job because I was so pissed off. Fuse was even worse. But the star of the show Ivan came through even though we had a hard time communicating he was resourceful with his phone translator and very pleasant to work with. They got the job done in the time allotted & so far so good. Although there was some minor details I think they overlooked. I will try to see if they can fix it.
I recently moved back into my family home, and the AC wasn’t working. I had a feeling something was wrong with the HVAC system, so I called Freon in San Jose. They immediately accommodated my crazy work schedule and sent a technician later in the evening—huge bonus for anyone juggling long hours. The technician arrived right on time, was professional, friendly, and very thorough in explaining everything. As someone who’s pretty familiar with HVAC systems, I appreciated that there was no upselling or fluff—just clear, honest communication. They diagnosed the issue quickly, replaced the capacitor and compressor contactor, added Freon, and had the system up and running during the same visit. Given that our unit is nearly 20 years old, the technician also gave practical long-term recommendations to keep it running efficiently. It’s rare to find service that combines transparency, skill, and genuine customer care like this. If you’re looking for an HVAC company that’s reliable, knowledgeable, and won’t waste your time or money—Freon San Jose is it. Highly recommend!
