"The technician Mohammed came out the same night, diagnosed the problem, and had my unit work in 7 minutes, no exaggeration. There was no additional for after hour service call fee, and how fast he had it working was amazing.I hope I don't have any other surprises with the A/C this summer or any other, but if I do, Rocky will be the first company I call, right after my insurance...lol"- Kenn B.

"Fantastic, same day service was provided and less than 10 hours my whole brand new AC system was installed and haul away the old junk free of charge. Rocky also provided me with a financing option that was unbelievable. Got my approval less than a minute. I highly recommend Rocky AC service and trust them 100% than they will take great care of you.Their prices were very reasonable compare to others like home depot or BGE. They charge double the price and Rocky did the same job and warranty for less. Thank you so much for your service to our Severn community. Thanks to panoo the tech you are great keep up the good work."- Sayyed H.

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.

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.

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.
