Reviews
Write a ReviewAmazing service very friendly. Great customer service experience!
Great responsiveness and did an awesome job for maintenance. Not that I want my furnace to break again, but if it does, I'd call them immediately.
Although project is not complete yet, impressed by their responsiveness and professionalism. Answered all questions and assisted me in finding a way to dispose of old and no longer neeed materials,
Received call advising of arrival time which was accurate; tech explained procedures involved in service and gave informed report on furnace performance compared to newer furnaces!
Replacement of old gas furnace with new efficient design, Job completed in one day, all work first class, customer service is responsive to questions and provides info in a timely manner. all around good job.
Iâ  ve been using A-1 for about 5 years, most recently today on my 1-year old house. A-1 has always been excellent in every regard, and I highly recommend them for your HVAC needs in San Jose. They were responsive, timely, and very very thorough in their work and reasonable in their cost.
Outstanding professional outfit. On time, worked hard, accomplished the complex task of replacing ducts in the crawlspace and attic efficiently. Competitive price. Very thorough communication from the boss; kept me fully appraised. I highly recommend this business. jps
