"The only time they had available was in the evening so I had to pay double the amount or a regular service call. I agreed to that because the temperature in my house probably around 40°. They gave me a timeframe for service from 5 PM to 9 PM and a service person would call when on their way. I was thrilled that Brett called me at before 5pm. Brett was very professional and thorough. He walked me through what needed to be fixed and prices. Within less than 35,minutes he replaced my broken igniter and answered questions about my desire to replace an 18 year old furnace."
