    Professional Service from Steve
    Steve arrived and answered all of my questions. The furnace is 22 years old and is noisy, but really no different than the 1st day we used it. He said it looked good. We discussed the new units are more efficient and quieter. I will be calling the office to get a quote. It was wonderful to have someone so professional! Thank you, Steve and A1 Heating and Cooling!
    Cindy Wilson
    Fabulous Work!
    Our heater died last week, and we got estimates. After reviewing three, we chose A-1 Heating and Cooling. They are professional, courteous, with great communication with the schedule. Work was done in a day, and they even cleaned out the ducts. FABULOUS WORK! Thank you, Hyman Kang, and your team.

    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

    Top notch experience from beginning to end
    A1 just completed the first of two installs needed for our home remodel. Top notch experience from beginning to end. Utmost professional team. Fast, efficient, and so tidy! It's challenging today to find a company you can trust. So thankful for the great experience and cannot wait for part 2 of this project.

    A1 Heating and Cooling did a great job
    A1 Heating and Cooling did a great job throughout the entire process, from reviewing and explaining all options to have a fair and competitive price to timely installation. The job site was clean, and the installing team was friendly and performed the install with no issues, as well as cleaned up and left the site cleaner than they found it. I would highly recommend A1 for all your heating and cooling needs.
    Brad Mandell
    Very professional and knowledgeable
    Porter was a very professional and knowledgeable air conditioner technician. Extremely helpful.

    Their work speaks for itself
    A-1 Heating and Cooling took on our central AC replacement and handled it with a level of confidence and care that immediately put us at ease; everything felt organized, intentional, and done for the long run, not just a quick install. What really sets them apart is that the quality didn’t stop once the system was in—the follow-up service has been just as strong, with thoughtful checkups and zero corner-cutting. They’re the kind of company that doesn’t need to oversell anything because their work speaks for itself, and that quiet reliability is what makes them stand out. Highly recommend.
    Olga Knauer
    Very knowledgeable and informative
    Porter was a nice guy and very knowledgeable, informative, and clear describing my AC issues and options.
    Jeff W (DrummerJSW)
    Great Experience with A-1 Heating and Cooling
    Great experience with A-1 Heating and Cooling. Sal, the tech, did an excellent job and finished the repair quickly. I’ll definitely be using them again for future service.
    Doug Merk
    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
    A-1 Heating and Cooling Were Great!

    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.
