Best Heating & Air Conditioning / HVAC In Cupertino

“I could not be more grateful to United for the work they did today. And I am especially grateful to my technician Chris Villa for being so professional, patient, and thorough in the work that he did. I called United for a leaky toilet, and they were able to find other problems and damage I didn't know about, and work with me on payment so I could get the repairs done that very same day! I was even given a free home inspection, checking every pipe under the house.

Do I wish it was a little less expensive? Of course I do, it's 2026 and the economy is in a downward spiral. But like I said, United worked with me on payment so I could get the repairs I needed done, and Chris was an absolute lifesaver. Whatever he's getting paid I promise you it's not enough! In less than 3 hours my flooding bathroom was fixed and several other damaged pipes and water fixtures besides!“

“Dan was easily able to diagnose the problem with our 27 year old air conditioner. It works like new now! Definitely would recommend him.“

“Vadim from Ampereca Appliance Repair helped us with a couple of jobs, including a washing-machine fix and a stove repair. He quickly diagnosed the issues and was knowledgeable, responsive, and thorough in the entire process. The quality of his work was excellent. Overall, I had a great experience and would gladly recommend them.“
