Steve and his team at Central Air did a great job from start to finish. We purchased a building that had been vacant for a few years that posed many additional challenges.  We did a complete upgrade to the HVAC system and ductwork that included 6 new units covering 17000 square feet. Steve and his team did a quality job and got it done on time!  They are also very responsive to any questions we have about the new system!  I highly recommend Central Air Heating and Cooling!

I wanted to compliment your company on the courteousness and efficiency of your service department. The response time was extremely good and technicians quickly diagnosed and repaired the problem. In this day and age, service is an afterthought for many companies, you should be proud of the positive image your service people project for Clean Air.

~ Howard Gartner, Owings Mills MD

This letter is being written as big thank you for the great service that Clean Air provided me with my heat pump. The technician was polite and professional. He listened to my heat pump issues and thoroughly tested my unit after all of his work was done. I will call on your company for any future work and will refer your company to people that I know.

I am writing to let you know how pleased I was with your personnel that installed my air conditioning system. Even though the heat was extreme they were diligent and continued work in order to complete the job on time. In addition they left my home neat and in excellent condition.

~ Catherine Haddon, Baltimore MD

This past winter, we had a couple of furnaces break down. We contacted Clean Air. Not only did they immediately respond to our problem, they were able to locate and install new furnaces within 24 hours. I would highly recommend Clean Air Heating & Air Conditioning. We appreciate your wonderful service.

~ Rick Fallin, Property Manger- Chesapeake Properties

In today’s world it is rare to find companies that show up when scheduled, get the necessary work done in a timely fashion, clean up after themselves, respond quickly to warranty issues, and are consistently competitive in their job pricing. Clean Air is one of those companies. Since 1976, I have used Clean Air on a wide range of projects.

~ John Doe

We had so many different companies tell us all kinds of different solutions to our HVAC issues. Chris came in and explained everything very simply and clearly to us and provided great options. He helped us the entire way through the financing company too. Huge shout out to the installation crew Bernie and Ron, those guys are awesome! Any company would be lucky to have such knowledgeable, respectful, and hard working employees. From start to finish this company was great.

~ Justin Pierce

I want to thank Custom/Design Heating & Air Conditioning of Fredericksburg for promptly helping my wife with air conditioning problems this past Friday, June 7th. While I was out of town she called Custom/Design and asked for help when one of our townhouse units failed on the eve of the upcoming weekend, leaving the upper two floors with temperatures in the high 80s. By the late afternoon, the staff, and particularly their Tech Bruce, had solved the problem. Because Bruce had visited the townhouse to do a semi-annual spring checkup in late May, they did not charge us for the emergency service. Great company that I recommend highly. You cannot ask for better service than what we received that day.

~ Porter Blakemore

They did an excellent job assessing, installing and condensate draining into our drainage pipes, a high efficiency gas furnace. The great personnel include chris the owner, Bruce (who has been doing our annual inspections and maintenance for 15 years), plus Mike, Bernie, Cody and Ron. Very
