My daughter was coming home from hospital and our heater went out. I called so many places to see if I could get someone to come out and told them the situation. US Heating(I talked to "Terry") sent someone out that day and took measurements and put the furnace in the next day!! They were so nice, so professional but easy going friendly people. And to top it??!!--They sent a box of Cheryl's Cookies to thank me for my business--never in my life have I had better service!!!!!!
