    Pleased With the Whole Process
    Just had a new HVAC installed yesterday. Pleased with the whole process from shopping for the right system to having a very efficient heat pump installed. Rav was very knowledgeable and understood my priorities right from the get-go. Over the course of a week, he gave prompt and detailed responses, and his professionalism gave A-1 the edge over another competitive quote. The team that came to install the system, led by Ramon, was polite and unbelievably quick. Thank you, Luis, Rodriguez, and Johann (and the guy who reminded me to buy new registers)! I would be remiss if I didn’t mention Desirée at the office, who was incredibly helpful! Can’t wait to enjoy air-conditioning this summer!!
    Clare Lee

    Great customer service attitude
    Danny had a great customer service attitude and met my system service requirements. He also assisted me by installing a new filter for my furnace after tuning my AC unit.
    Gloria Stinson
    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.

    It runs perfectly with no start-up noise
    I had a new model of Lennox gas furnace installed, but the factory part that regulates gas pressure needed to be replaced after installation. It was causing a start-up noise that it was not supposed to be making. Lennox supplied one with a lower gas pressure. Francisco came and replaced the parts, and it runs perfectly with no start-up noise. He was polite, competent, and thorough.
    Beth Cohen
    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.
    jeffrey davis
    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.
    Marjorie Grimm
    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.

    Danny didn't do any sleazy sales pitch or upsell.
    Got the Home Depot Black Friday deal for $8.88 furnace tune-up. Danny came and gave my furnace a look over and shared the condition of my furnace. It's more 'inspect' than tune-up. But, my furnace report came back healthy and Danny didn't do any sleazy sales pitch or upsell.
