Testimonials for Supreme Air

“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” 

Angela E., Glen Burnie, 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.”

Tom M., Severna Park, MD

“Alex Kougianos came out to the house, assessed our needs and proposed a system that was within our budget and exceeded our hopes. To replace a entire hvac system in a single family home is a huge undertaking, but Supreme Air did it quickly, efficiently, and professionally. Ryan, Bruce, Troy, and Josh treated me like a friend and answered all of my questions while installing our system like the experts that they are. I will recommend Supreme Air to our homeowners association as a dependable company for my neighbors hvac needs..”

“These guys set the bar–high. Compared to other contractor offers (quotes) & presentations. From start to finish these guys were very good. They showed up on-time or called if the were delayed. Follow-up quality control–excellent. Our HVAC was installed in two days. Every step of the process was covered step-step, no hidden charges and financing choices were–excellent. I can’t understand “how” the others stay in business, Do your homework and interviews, check references, etc, you can’t be WRONG with Supreme Air, LLC..ALEX & Crew Thanks!!.!” 

Ed V., Owings, MD

“From the first meeting with Supreme Air, the experience was completely positive. We picked them as our supplier quickly, even though we took some time to actually schedule the installation. We found them to be professional in execution of the project and polite in demeanor. It was a pleasure to have them in our home..” 

John G., Forest Hill, MD

“Denny and Alex really did a quality job installing my Weil-Mclain Boiler and indirect water heater. It works flawlessly and looks beautiful! He also gave me a more reasonable price that the other 3 contractors that gave estimates. I will definitely recommend Supreme Air to anyone that needs heating or AC work done..” 

Kris K., Halethorpe, MD

“All of the Supreme Air folks were punctual, professional, courteous and really cared about our needs. They were easy to work with and did what we asked and what they had to do to get the job done, not to mention affordable unlike the 5 other companies we spoke to. We had a few concerns after completion which were addressed immediately and have the warm fuzzies about these folks. I have found my heating and air conditioning contractor and if you are interested in not wasting time or dealing with frustration over a contractor’s performance or quality look no further, these folks really care about you. Thanks Supreme Air.!”

Gordon M., Baltimore, MD

“Everyone was customer service-oriented and technically competent. this began when the estimator provided a full packet of company data from the get-go. The workers did not rush to get the job done but were not pokey, either. They installed a quality system at a fair price and even coordinated with the insurance company in arranging direct payment. No one likes to go through the hassle of estimates and trying to judge who’s telling the truth or the half-truth. These folks were a cut above all the other companies I dealt with. They made a tough situation much more bearable..”

John H., Annapolis, MD

“They were awesome. They were courteous, timely, and they delivered on all that we contracted for..”

Wendy R., Parkton, MD

“Very honest, Alex came to the house was here about an hour measuring looking around and gave us the best possible price. Explained the best way to make the new units work to the best potential. Got the job done in a day. Would recommend this company to anyone in need of new furnace and A/C. Thanks..”
