I had an bit of an emergency with my furnace and DHL was the only company that took the time to come around that same day. Mark ended up replacing my furnace as it was old and worn out. He also took the time to clean up all the excess ducting that the original builder had put in but didn't take the time to route it properly and it took up a lot of room and now my furnace room is big and uncluttered. He was always here when he said he would be and was very courteous and made sure he always cleaned up afterwards. I have since hired him to install a new A/C unit and also tune up my infloor heating boiler. I will not waste my time calling other plumbing and heating company's anymore as DHL seems to have everything that a customer is looking for
