Best Heating & Air Conditioning / HVAC In Milpitas

“Sal was great he was quick and very knowledgeable really happy with the service 5 stars all the way“

“Excellent service from Stephan Reich. He was professional, knowledgeable, and diagnosed the issue within 15–20 minutes.

The $200 consultation fee is on the higher side, but it was absolutely worth it. I’d rather pay more for a skilled technician than deal with guesswork or wrong fixes. The issue was a simple air filter problem, and Stephan clearly explained system operation, maintenance, and how often filters should be changed.

They’re based in Milpitas and service Dublin as well—glad I found them. Plus, Stephan is easy to talk to and very approachable. Highly recommend.“

“My experience with Upgrade Home Services was excellent from start to finish. The team was professional, reliable, and very knowledgeable. They clearly explained the home improvement process, completed the work on time, and delivered high-quality results. Communication was smooth throughout, the work area was kept clean, and the final outcome exceeded my expectations. I highly recommend Upgrade Home Services for dependable and professional home improvement services.“

“John sent his employee Joey to inspect my 20 year old Frigidaire gas furnace, pointed out a few minor discrepancies with the blower speed and gas supply and adjusted the latter. He was right on time, knowledgeable, polite and very personable. Highly recommended.“

“Furnace
stopped blowing hot air mid-night so called All Heating and Air Conditioning emergency
line. Tech came out fast, replaced a blown fuse from power surge and checked the coils for
dirt buildup. Explained annual maintenance to avoid repeats, bill was steep but included
after-hours fee.“

“My Lennox AC unit was not cooling the house even though air was blowing so I had a different HVAC company come out and the guy told me my compressor was dead and quoted $4500. When the tech from A Plus came out to give me a second opinion he said the compressor was fine and topped off my refrigerant and the AC is working now. He was professional and friendly and wouldn’t even accept a tip. So glad I called them and I will only use them going forward. THANK YOU“

“We had our A/C unit and our hot water heater tank replaced. Tony and his staff was so professional and went well above and beyond to make the entire experience easy and perfect for us. Not only did they all do a great job but they were kind and respectful not only to us but to our home and property. I would highly recommend TFF HVAC to anyone.“
