My system just stopped working. I called this company after hours. Received a prompt call back the next morning. The service guy came out 24 hrs later. He did a complete review of the system until he found the issue and fixed it. I am so grateful for this company and their service guys.

My family called four places after their 22-year-old unit stopped blowing cold air in a heat spike. A1 was the only company that prioritized us and scheduled us the same day.

Great service!

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.

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

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!!

An HVAC emergency typically involves situations where your heating or cooling system stops functioning entirely, poses safety risks, or causes significant discomfort. Examples include gas leaks, electrical issues, or complete system breakdowns during extreme weather conditions.
Are emergency HVAC services more expensive?
Emergency HVAC repair services may have additional costs to cover the urgency and out-of-hours labor. We strive to keep our rates competitive and will provide an estimate before any work begins.
Can I prevent HVAC emergencies?
Regular maintenance can help prevent HVAC emergencies by identifying and addressing potential issues before they result in system failure. Scheduling seasonal check-ups and replacing filters regularly can also reduce the risk of emergencies.
Is it safe to attempt DIY repairs?
We strongly advise against DIY HVAC repairs. These systems involve complex electrical and mechanical components that require professional knowledge. Attempting repairs yourself can lead to safety hazards or additional damage.
