A Supreme Heating & Air Conditioning

Great company. DJ took care of getting me some water heater estimates quickly. Once my decision was made, I put down a deposit easily over the phone on a Friday. Got a call on Sunday evening and was told they could be there Monday morning to install my new water heater.

They showed up when they said they would and everything is now done. Everyone was courteous, professional and respectful. They registered the warranty making any issues easy to deal with by contacting them. Thanks again, A Supreme H&A!

Came back from vacation to my AC unit not running. Call them and they were out the next morning. Both technicians were courteous and explained the issue to us and told us how to handle the issue if it occurs again. Highly recommend

This is a 5 star company all the way around.. They come out twice a year to check our heating. And AC and the technicians are all very courteous and knowledgeable. Edward came out today and did a great job.

It was easy to make an appointment. The service Tech arrived as promised. He was knowledgeable, thorough, and efficient with his diagnosis and repair. I would recommend them and use them again.

They have always been there to help and go out of their way to get things done quickly and on budget. Also have a great service staff DJ has been my PM service tech for a few seasons. It's great to know who's coming into your home. Highly recommend.

Alvin, A Supreme HVAC Technician called 18 minutes before arriving time to let me know he was on the way. He arrived promptly and on time. Was courteous, knowledgeable, and informative of what it had done and the performance of the system. Set the thermostat for me when I asked him to change the setting. He is an excellent worker.

We have used A Supreme for the few years we have been in Maryland and have always been happy with their work. I always receive an email and text with a photo of the technician who is on their way. I like knowing who to expect at my door. I receive a message reminder when our systems are due a check up. I have always gotten a clear explanation of any work that needs to be done. We will continue to use A Supreme!

Alvin and Mike did a super job leveling out our heatpump. They went above by making very good drainage for the unit. They installed insulation. Alvin did our maintenance and installed a new thermostat. They were on time and very professional. Prices were fair. Alvin made sure everything was cleaned up and checked out.

This company was prompt, courteous. they even called when intransit to my home. their service fee was reasonable.

The install team was amazing! all business, nonstop till job completed. Complete cleanup and haul away of the old system and all debris. They also answered all of my questions regarding the newly installed system, and the failure of the old system. I don't know where you could find better service!

The previous owners left this company's business card behind and we thought why not give them a try? I was able to submit a request online last night and had a confirmed appointment time first thing this morning for today! That's amazing responsiveness and the online request took some of the anxiety of booking services away! Our technician DJ was incredibly professional and provided us with lots of information about our options to continue to improve our system. I would highly recommend this company for yearly maintenance! We look forward to continuing to work with them.

Update: DJ has continued to be an incredible technician! The company's customer service can not be talked about enough. We are beyond impressed and thankful to have such a great company caring for our home!
