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

B Smith, Frederick, MD: Remove incorrectly installed ductless split heat pump in sunroom and replace with high end quality Mitsubishi system in sunroom. Excellent service. Rapid response. Phone call follow-up to check in 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.

Mitsubishi CITY MULTI Minisplits

HHI is experienced and honorable. HHI demonstrated and conviced us their is no comparison - FUJITSU is the best. Last year we purchased a Carrier for our Formal Florida room and we are freezing. Unfortunately, the contractor was not trained properly by Carrier and the unit is too small. We will have HHI remove the unit and replace it with a FUJITSU.
