The furnace is quite loud and tends to clog its injector orifice.
The Heart of a Quality Heating and Furnace for the long run
March 12, 2023
Burns efficiently and replaces the original oil forced hot air system that was 28 years old. Runs smoothly with programmable thermostat and maintains the desired temperature. I have a two\-zone system, 2 story residence approximately 1,700 sq feet and this unit has power to spare. Please with the sound of the furnace as not loud at all and considerably quieter than my last system. I like the steel construction and housing of the furnace.
Already had to have a part replaced and its only a year old, heats well

Nice But Loud

It is located in a closet near my bedrooms and seems loud when it is running. I can't sound proof the closet because I need to have air vents for the combustion. A light sleeper would have difficulties with the noise of the burner.
Quiet and Efficient Unit
