    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.

    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.

    Overall really good experience
    Just had a new furnace installed. Working with A1 HVAC couldn’t have been smoother from start to finish. Upon submitting my issue with Home Depot, I got a text from Bill saying he can help. He came over to my place, diagnosed the issue, and gave me a really fair quote. Three days later, a crew showed up early in the morning and installed the new furnace by early afternoon. Overall really good experience and I’d definitely recommend going with A1!

    Supervisor and workers are very courteous and professional.
    I bought a unit from these guys 4 years ago. I needed some help with the unit that is still under warranty. They came the second day; the first day they were busy. But the second day they came and took care of the problem. Supervisor and workers are very courteous and professional.

    Hyman at A-1 H&C was exceptional!
    Hyman at A-1 H&C was exceptional! I reported the AC problem on Sunday. Their office was closed, but he called me back within the hour and set up an appointment with a tech for Monday. Hyman arrived at our home on Monday before the tech to check out the problem and called the tech to inform him what needed to be done. The tech arrived on time and was friendly and proficient in diagnosing and repairing the problem—capacitor needed to be replaced. The downside of the experience was the cost. I was charged 40x the cost of the capacitor. I later priced it at HD for $18!

    Had such a great, easy experience with this company. From Hyman in sales, to Evuardo and Mel for install, and Francisco as a tech (and all the other team members who accompany them—I forget everyone’s name!) it was a great experience for a brand new install. Thanks A-1! Highly recommend.

    Fixed the issue at lightning speed
    I had an issue with the AC unit which was not cooling. I called them and service person Porter showed and fixed the issue at lightning speed. He knew what was wrong the moment he saw the unit and he was spot on with the diagnosis. I would highly recommend Porter and A1 Heating for their best service.
    Vamsi Krishna
    Very responsive in scheduling the appointment.
    A-1 was very responsive in scheduling the appointment. Technician arrived on time and made a thorough evaluation of AC and furnace. We have very old systems, so it was good to get cost of repair vs. replacement vs. heat pump options.

    He was a great salesman and I think I will buy.
    I had P. Tanner to my home today. He was giving me information about a sump pump. He was a great salesman, and I think I will buy. My furnace costs $359–$525 to run monthly.

    Marian at A1 Heating and Cooling was great at helping me to arrange for my A/C repair, especially when I had multiple problems with the parts department. Technician Francisco was professional and explained the immediate work and future work requirements really well.

    Sam Park
    Francisco is a top-notch technician.
    We noticed a leak coming from under the heat pump and needed a prompt response. Francisco arrived right on time and conducted a thorough inspection of the unit and clearly explained what was causing the issue. He walked us through our repair options without any pressure, making sure we understood everything before moving forward. What really stood out was how knowledgeable and informative he was—he offered helpful tips for maintaining our unit to help prevent future problems. He worked efficiently and with great attention to detail, and when he was done, he left the area spotless. We are genuinely impressed by the high level of service that A1 Heating and Cooling provided. Francisco is a top-notch technician. Highly recommend!
