Best Heating & Air Conditioning / HVAC In Milpitas

“Unbelievably quick. Labor day weekend, and the AC went out. Sal showed up 30min after I called and got it back working again in less than a hour. Reasonable rates too. Would absolutely use these guys again.“

“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.“

“We met Victor when he responded (on a Sunday) to our furnace issue during the Thanksgiving weekend. He got our furnace back on that day. We greatly appreciated his responsiveness and expertise to restore our furnace operation on that cold weekend. Our confidence in Upgrade Home Services (UHS)led to our contracting them to replace our old HVAC system with a new Amana heat pump system. UHS replaced our gas furnace and AC unit on time and on schedule. Unfortunately, we had to call Victor the next day to repair a wiring issue that temporarily halted our system's operation. The good news is that Victor quickly responded to our call that day and repaired the wiring issue. Overall, we rate UHS five stars for Victor's responsiveness and expertise. The only unfavorable comment I have on UHS is their team of installation technicians are not very responsive to any questions during any phase (demo, prep, installation and test) of the installation project. Whenever I hire a contractor to work on my house, I make it a habit to understand what the contractor plans to do before they do it, so that there are no surprises and that I'm okay with any their modifications to my home. However, if you are the type of homeowner that's hand off and is comfortable to let the contractor work on your home without questions or desire to observe; this is probably not an issue for you. But if you are like me, and wants to know the details of what the contractor's plans for your home project; or may want them to answer questions prior to a major installation phase, you may want to address this with Victor prior to contracting them for any home projects.“

“Global heating and cooling service just helped replace my 17 years old AC and furnace system with a brand new hybrid system, their work is always reliable and will not stop until finding the best configurations for the customer. I am so happy with my brand new hybrid system and google home nest thermostats !“

“The technician came and diagnosed the A/C proplem quickly and took time to explain. Very pleased with the fast service performed by Victor.“

“A-Plus replaced our 25 year old furnace and A/C unit with a new more efficient Lennox unit. They also replaced our ductwork as certain rooms in our house weren’t getting sufficient air flow. They were very knowledgeable and sized our system accordingly. They also resized the intake to improve the flow. The cost of unit and installation was very reasonable compared to a 3rd party through Home Depot. Almost 2/3 the cost!! Hopefully, this new system will last us another 25 years. A+“

“After my heat was out for two days and it was freezing, they showed up on a very cold Sunday to fix my entire heat pump system and thankfully were able to fix it. I so appreciate their help.“
