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
Great service
Excellent company from value to quality work. Sales Rep. Robert Ray is very knowledgeable and a true professional. Robert helped us in getting a quality AC unit for an excellent price. Very happy with the experience from beginning to end.
Responsive and professional
The team got the work done in 2 days. They kept the noise down as possible. Live recommended them for my mother’s roof.
Buying a HVAC could be a stressful experience. I decided to go with A1 (Robert) because : Very clear they want to EARN my business. Gave me multiple options based on my need. Help me navigate through the rebate process. It was a very competitive package out of all the 5+ manufactures/contractors I interviewed. They continue to impress me post-sales: Technicians (Uly) were super clean/efficient throughout the whole process. The Rep would check in each day of the install. You could tell Sales/Tech have a tight team. its great end-end experience, I was skeptical at first but now I can say I'm a happy customer !
Same day estimate, courteous, problem solvers, recommend them to others.
