Our tech was very professional. Knew what he was doing, told us exactly what was wrong. Took his time checking our system. Very helpful.

Geothermal unit had a “lo press” fault light. Youssef and helper quickly diagnosed the problem as a faulty motor capacitor which prevented the compressor from operating. Youssef was able to explain the fault and operation of a geothermal system in straightforward terms. They had the part on the truck and replaced it in a few minutes. Both service techs were professional, very polite, wore shoe covers while in the house, and checked out operation of the system after repair. Nice job!


Supreme Air was very easy to deal with and very thorough. The technicians were always helpful and Supremely knowledgeable. Thank You to everyone at Supreme Air of Baltimore MD.

Can’t recommend Supreme Air highly enough for geothermal heating and air conditioning. Great products and quick service. Denny and Alec care about their customers. Youssef and Colin are the best techs ever!

I was extremely please with Supreme Air’s courtesy, professionalism, quick response, and subsequent follow-through from the initial call to the 24 hour hot line to the technician, Christopher, leaving. The call center was professional and courteous and the follow-up emails and text were timely and helpful in knowing when they would get here. The technician, Christopher, called about 20 minutes ahead of time which was followed-up with a text and email…very convenient. Christopher was quick, thorough, on-time, and professional. He diagnosed the issue in less then 5 minutes and was here less then 30 minutes.

Had a busted main line under an old row house. They got someone out the same day and had the work done the next morning. Derrick was our technician. He was courteous and professional during the whole ordeal. They text an alert (with a picture of the technician they are sending) when they are sending someone. I’d definitely call these people again for help with HVAC and plumbing.

I called Supreme for service on my Carrier mini-split system, which was no longer producing heat, and had a positive experience. My technician was courteous and explained the situation clearly. He left me with a working system and he came in under budget.

Youssef is an excellent technician and a very nice person. He explains the system and works with the customer. He is very smart and knowledgeable about the Geothermal systems. When he doesn’t know something he finds out the answer rather than ignoring the problem or making something up!

I can’t say enough positive things about Supreme Air. We woke up yesterday morning to a dead furnace, the house cold. I called at 6:20am, the technicians were here to diagnose by 9am, and as of 4pm today, one day later, we have a new furnace-AC installed and working. Meanwhile, they dropped off enough space heaters yesterday to keep us warm overnight. There’s no such thing as better service than that. And the price was reasonable – we checked. Five stars well deserved.

This company is GREAT! So they arrived within 1 hour of my call and I received a text and email of who my tech will be with a picture so I know who will be knocking at my door. The tech was very friendly and respectful of my home.

He diagnosed the issue and it appeared we needed a new blower motor. Of course this happened the day before the coldest days ever. They located a new motor , went to get the part, and returned to install .

Everyone I spoke with from the owner, tech, and office secretary were super friendly and helpful. Love this company and thank you for keeping my family safe, warm, and comfortable during the polar vortex!

The technician Colin was prompt, courteous and above all knowledgeable. The issue with our Carrier furnace was diagnosed properly and fixed within 20 minutes. We will definitely use Supreme again. Pricing was fair and we are very pleased with their work.

Chris did a fine job, but he didn’t have complete command. So the project deserves additional work, but I can think of no one more qualified than Chris to complete the job. He returned today and fixed the third unit, making the whole house much more comfortable. Bless him!
