HHI HEATING and AIR CONDITIONING servicing FREDERICK, and HAGERSTOWN Maryland

We just wanted to let you guys know how much we love our Mitsubishi A/C units. That was one of the best improvements that we have done to this house. The units performed perfectly this past summer. If they perform just as well this winter we will be very satisfied. Ed did a great job installing the system and we thank him very much. Is there any thing we need to do to get ready for winter? We only regret that we did not have a unit installed in the basement..

Thanks again,

Dewey & Peggy

Kevin F, Walkersville, MD: I would like to thank you and your company for the excellent installation of my Mitsubishi Mr. Slim, our birds are very happy and most of all my wife is ecstatic. I have told many people about how polite and prompt your company was with starting from the estimate to completing the job, even when the drills and drill bit broke. Thanks again If you ever need a reference please don't hesitate to call Thanks again for a job well done

K. FLuke, Damascus, MD: Installed Mitsubishi Mr. Slim - ductless system, Mr. Haynes was very professional and very thorough with the complete job. I would recommend him and his company to many other people who would be in the market for this or any other type unit.

B Smith, Frederick, MD: Removed incorrectly installed ductless split heat pump in sunroom and replaced with high end quality Mitsubishi system in sunroom. Excellent service. Rapid response. Phone call follow-up to check on satisfaction. Very patient and thorough. Have already made appointments with Haynes to work on other home projects. I will recommend to all friends and neighbors.
