Excellent service!!! Answered all my questions too : )


Mike did an excellent job of checking our furnace system, explaining to us exactly what was wrong with it & why it needed to be turned off due to it being hazardous and what to do going forward. Our system was 22 years old and it was leaking on the inside & was very rusted. I really appreciate his professionalism & expertise!

I performed a precision tune up on the furnace. This furnace was in poor condition. I do not believe this furnace has ever had maintenance. I checked all electrical components, gas pressure, operations and all safties. I also cleaned and waxed the furnace. Other than being dirty the furnace is working good at this time.

I performed a precision tune up on the heating system. I replaced the furnace filter, checked all electrical components, gas pressure, set up humidifer, replaced the pad, and cleaned and waxed both the furnace and humidifier. Everything is looking and working good at this time.
