I was panicked when my heater went out since it was freezing cold with tons of snow outside. This happened on a Sunday so I called first thing Monday morning. Mrs. Madden was so friendly when she took my call. Her husband came up our snowy road that same day. I was so relieved when it turned out he only had to replace the thermostat. I am grateful for their service & will use them again. Thank you..thank you..you never will know how much this means to me.
