Paul and Mike showed up on time to do the work. They are both very professional and keep my hallway clean after work. They finished their work earlier than schedule. I strongly recommend Freon to anyone who want to have new Mitsubishi Heat Pump HVAC installation. Still wait for Sunnyvale Permit inspection schedule

Maximo, was on time, super professional and knowledgeable. He took pictures, explained what was going on and made sure we approved all the work that was to be done. He's EXCELLENT !
Our experience with Freon HVAC has been exceptional for a full panel upgrade to 200 amps and installation of a new Mitsubishi mini-split system in an old house. We took quotes from 4 different top rated hvac providers in the San Jose area, before deciding to go with Freon. I appreciated the honesty and detailed analysis of our needs by Slava when he first showed up to do an estimate. He asked a ton of questions, checked the house for existing setup, wiring, possibilities, and discussed multiple possibilities including ducted, gas, hybrid, and heat pump only. Once we decided to go with a specific type of configuration, he gave us multiple options. Their pricing was competitive and while it took forever for PGE to get to the wiring/transformer upgrade, Freon's team worked with them patiently to meet our needs. Special thanks to Jessica for regular follow ups with PGE and us. Once PGE scheduled the wiring upgrade (after 3 months), Freon's team was prompt and did a very clean install including all internal wiring and drainage work. They ensured city inspection was scheduled promptly and addressed all city concerns for a quick approval. I have not dealt with a more professional and competent crew in this area in a very long time. Would love to do business with them again.

I usually doubt perfect 5-star ratings, but Freon completely earned theirs. My AC/heater combo unit broke, and every other company told me I needed a total replacement, quoting me between $9k and $12k.
Freon came out to inspect it, and later that day, they gave me a quote for just $3,000 to repair it. I signed the contract that night, and they were back to do the work just 5 days later on June 19th.
The tech replaced the compressor to get it running, but didn't stop there. He thoroughly tested the system, caught a power issue, and replaced the compressor relay and expansion valve to ensure the unit wouldn't break down again. Outstanding service. I'm finally set for the summer and winter. They deserve every single star!
