    You Exceeded My Expectations
    Ubaldo and his crew were the most professional and enjoyable group of people I have done business with in. I can't remember ever having a more pleasant group around me. Everything about this job was perfect from the first call to your office, the salesman who was on time, he asked for my expectations, and then he explained what I could get away with, and then he laid out what I should get, not the most expensive either. I accepted his recommendation, prayed for the best. I had just had a terrible experience with Atlas Trillo/Lowes the month before, so I was a bit apprehensive, to say the least. Ubaldo and his crew showed up on time. I woke up a bit before the start time and saw the crew quietly waiting out front to get started. From the second I met Ubaldo and his crew I knew I chose the right people. I can't say great things about this group of hard-working professionals, Ubaldo, Arturo, Carlos, Marcos, Melvin. What a great bunch of guys. First thing Ubaldo and Arturo did was walk me through the process with a timeline, and that was exactly how it went, no hiccups but always ready to assist any way possible. Thank you Air Sharks, you exceeded my expectations with service that was far above the norm. Bryan Croy and family

    A-1 Heating and Cooling Were Great!
    A-1 Heating and Cooling were great! They answered their phone right away, scheduled a very efficient service (that was not delayed), and clearly explained our issue. They were also very affordable! I’ll be calling them back for any future needs.
    Christine Hanks
    Reliable, Honest, and Efficient
    I had a great experience with this AC and heating crew from start to finish. They were on time, professional, and extremely knowledgeable. They took the time to explain what was going on with my system and made sure I understood my options before moving forward. What really stood out was how friendly and respectful they were, and they kept everything clean while they worked. You wouldn’t even know work had been done when they left. It’s hard to find a team that’s reliable, honest, and efficient — but these guys delivered. I highly recommend them to anyone needing HVAC service.
    George Magana

    He arrived on time and efficiently completed the job
    Gerry came to my house to do an HVAC tune-up. He arrived on time and efficiently completed the job. In addition, I asked some additional questions around my vents which led to a request for quotes to do further work.

    This service technician named Danny was great
    Arrived, introduced himself, placed covers on shoes, and tried many ways to get the thermostat to work correctly with no luck. He advised me that he had to call his supervisor to order a new thermostat because it was not connecting to my Wi-Fi. This service technician named Danny was great, polite, and courteous. Thank you.
    Maria Cisneros Knight
    It was a great experience as always
    Getting my unit's filter changed and the mechanics of my air and heating conditioner checked on was a very pleasant experience. He helped me clean up the outside of the unit. He changed the filter. He was very careful about my new crawl space covering, and we cleaned up and put on the cover to the unit. It was a great experience as always. I love doing business with A1.

    They are fantastic at what they do
    A-1 has been my go-to vendor for servicing the HVAC system in our Sunnyvale townhome. They are fantastic at what they do, very courteous, and no up-selling. The technician, Francisco Ramir, who visited our place in October was very knowledgeable and meticulous. I would recommend A-1 to anyone wanting to maintain or repair their HVAC system.

    Very professional and a very thorough job.
    Great experience with A-1. They had to reschedule once, but when they arrived, Danny did a fantastic job with the HVAC system inspection. I shadowed him to all of the areas of inspection; he explained what he was doing and gave recommendations for how to maintain each part of the system. Very professional, and a very thorough job.
