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.

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.

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)

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

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
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.
