Technicians are always on time, skilled, friendly. We’ve been pleased with the product and service.

- Roger F.

Showed up well within the time frame he said he would (said one hour, more like minutes). Fixed my furnace in time for the really cold weather. Will hire again.

- John R.

Always available, reasonably priced. They didn’t do my installation but have handled service issues and I’m very happy

- Manish O.

The technician was very helpful in explaining why my AC blew of a fuse and offering recommendations for repair.

- Sarah M.S.

Professional, knowledgeable, polite, honest and efficient. Would happily recommend this company to my community and neighbors.

Yoseff just made service call. Friendly, thorough as always. Thanks.

- Todd O.

Called for after hours service due to a broken AC system in my house. Extremely pleased with the service. Collins did a phenomenal job in a very short time. Will be using this company again in the future.

- Zach T.

First class organization. Quality work and quality service. Hard to find these days. The owners and the team are a pleasure to work with. Honest people who are focused on the customer experience.

I am beyond satisfied and thankful for the service Supreme Air, particularly my technician, Chris, provided this week. From the moment I called the person I spoke with on the phone was very kind, professional, and made sure I would have a technician out as soon as possible. The technician, Chris, was also kind, professional, trustworthy and reliable. He worked around my schedule and stayed until the job was complete. When your air stops working when it’s 90+ degrees in Baltimore, you couldn’t ask for better service!

The most complete sales presentation, on time installation with great cleanup. Furnace works like a charm.

Alex was early for the initial appointment. His pricing was competitive and the work was scheduled and completed on time. The team of John and Jason did a great job and left the site clean and all systems operational.

Manuel D., Columbia, MD

Very Fast and professional response.

Brian G., Westminster, MD

The techs were very friendly and did a great job. Would recommend to anyone.


We had a great experience with Supreme Air from the time they came to give us their proposal until after the installation process. They were very thorough and explained everything to us. Everything was installed in one day and they were very neat as they did the install. I would recommend this company to everyone.

Jerry J., Crownsville, MD

The entire team at Supreme Air was excellent. I got a prompt return to my initial call and all follow up was done expeditiously and with the utmost professionalism. I highly recommend Supreme Air.

Terilynn M., Windsor Mill, MD

Supreme Air was a pleasure to work with and an excellent choice. Alex gave me two options for replacing a converted coal furnace. After choosing the high efficiency unit, the installation went as planned, including the subcontracted asbestos removal from the old furnace. The work crew was polite, responsive and responsible. When the temperature decreased and it was becoming more difficult to warm our offices with space heaters, the crew stayed until after 7pm the final day to ensure that we had heat before a snowstorm was coming. Overall a very positive experience.

Alex Kougianos came to my house, listened to my problem and suggested a heating system that met my needs. Supreme Air did a great job installing my new furnace and hot water heater. During the installation, Denny and Alex were very patient, and took care of all my concerns and answered my questions. The technicians were professional, courteous, and responsible. Supreme Air also performed maintenance on my central air conditioner. The entire experience was positive. I would highly recommend Supreme Air for ay heating and air conditioning needs
