MY A/C didn't work the other day so I called to schedule an appointment. Found out this morning that our heater was also not working. Gave the McCullough a call before 8am to see if they could fit us in earlier with how cold it is outside and they were ...able to accommodate. This is the second time we have used their service and I they have always been professional and thorough. I would definitely recommend their service.Read More...
