10/10 · New Air Conditioning Installed

"From my first enquiry to completion of works I found them to be very courteous, hard working and competitively priced. Dan carried out a full survey and gave a cost breakdown for works. A date was booked and the guys turned up on time and work was completed within the given timescale. They were very polite and tidy and even vacuumed after completion. I am so happy with my new hot/cold air conditioning unit which will enable me to work comfortably from home and sleep at night. They even sorted my dripping tap free of charge! I would highly recommend DM Heating and Cooling."

"Dan and his team arrived at the given time and carried out the replacement of my boiler and all radiators in a speedy and efficient manner.
