Heat Pump Repair in Ellicott City, 21042
“Henry at GreenFox Heating & Plumbing completely saved the day!!! Our heating unit was really struggling with the onset of cold weather. We are renters & not super familiar with our older system. Henry diagnosed the issues, cleaned up our unit, explained his repairs and replaced the parts/wires. Our unit has never run so quietly & efficient!! Literally saved us from having a very cold winter. Thank you Henry & GreenFox Heating/Plumbing. You guys are the best! 5 stars, highly recommend!!”
Heat Pump Repair in Rockville, 20855
“I had great pleasure of enjoying the services of Owner Mr. Hussain Ali, P.E., for over 25 years. I was not in the position of writing reviews for his company to avoid conflict of interest. I was a county official, now I am retired.
My heat pump had some issues recently which got fixed with minimal expense. He and his staff (both administrative and technical) were very knowledgeable, thorough, extremely courteous and professional. In the past, I recommended his services for some community big projects, his company performed very well. The feedback I received was, that the job was done professionally and at a very reasonable price.
Hemal Mustafa, C.B.0.”
