I've been working wit Great Mills Heating and Cooling for two decades, thay have always demonstrated integrity, responsiveness, and professionallism rarely seen in today's product and service market. Thank you Kirk and team!

Great service. Techs are well trained, competent and personable. Helped with understanding new wifi thermostat. On time for appointment. Very satisfied customer

this company is very honest. they dont try to sell you new AC/HEATING equipment like many of the other companies. I would HIGHLY recommend them if you need any of their services.

We had to have a new A/C unit installed due to problems with our previous Unit. They came out and installed our new A/C unit and Air handler in one day. Very professional and courteous. I would highly recommend!

Professional and didn't try to make me feel like more was needed than just a repair. Other companies previously used by older family members tried to use scare tactics to attempt sales for high priced replacements,
. An Honest company finally!!

Great Mills Htg & Air have been keeping my central air system working at top condition since I moved to Southern MD in 1997. I just had them check my furnance in prep for Fall & Winter. Ronnie did a great job checking everything.

I have always relied on Great Mills Heating and Air for my HVAC needs. Over the years I have bought 4 systems from them for my house and my rental properties. Very satisfied with their service.

FEB 2025. Great Mills HVAC removed my old oil furnace and air conditioner and installed a new heat pump HVAC system in one day. The team of 5 polite, expert technicians performed like a well correographed ballet. We had an up and running furnace in one winter day.

We've been doing business with GMHVAC for over 15 years, and their service is always quick, professional, and friendly. Their services included biannual servicing, and a new replacement system when needed. Would not think of going anywhere else!!

Great Mills Heating and Air has installed the various house HVAC and serviced the seasonal A/C and Heat every year. They are very professional and competent beginning 2002 and thru this year 2024.
I would recommend the co to all homeowners in St Mary’s County.

When building Swanendele Inn Great Mills installed our Geothermal heating systems - a longterm money saver. Maintenance has been excellent and reasonably priced. As a smaller firm, Kurt and other staff remains involved and KNOWS the systems. Highly recommended

Very good response time. To our AC units not working. They got it fixed the next day. It was hots day of the year. They were right on it. And very not bad with the bill. Price was reasonable. Well organize company if you need their service for heating and air conditioning please look them up.

GMHAC installed a high-efficiency system in Spring 2024, and it's been performing flawlessly ever since. We've already noticed increased comfort and reduced cooling costs. With Kyle's (GMHAC's Technician) recent thorough and professional winter service on both our Carrier systems, we're confident we'll experience the same comfort and efficiency throughout the winter months.

Been using Great Mills Heating and Air for over 25 years. They provide excellent service. Employees are professional, knowledgeable and friendly

Great Mills was Johnny on the spot. They were proactive, professional and very competent. I would use them again for any heating & air conditioning needs.

The techs are honest in their diagnosis offering the simple and accurate solution, explain their findings & why they chose that route, and always on time. I have used them for my rentals, and referred them for business clients. A solid positive experience. The customer service on the phone is always helpful, and over & above to make sure the details are attended to. My go to for HVAC.

Great Mills HVAC was quick to respond to my emergency call for repair. The problem was quickly discovered and solved on site.
The technicians were professional and polite. The head technician explained details re the solution. I would recommend this company to others,

We had a new above ground oil tank installed. The team was prompt, courteous and very thorough in their work for this installation and left the work site in better condition than they found it. I'm glad we called them.
