• My gas heater works fine but it is making noise. Is that a problem?


    When my 1st floor gas heater turns on in the attic it is quiet as a mouse. The upstairs unit, by contrast, ignites and heats as well as the other, but there is a sound like the whir of a playing card in the spokes of a bicycle. Is that a loose fan or something? It works fine, but the noise is a bit concerning. Thanks!

    Depending on the age of the furnace, the main blower assembly or draft inducer motor can cause the type of noise you described. The noise could indicate a simple problem but at the same time it can lead to or be the start of a major problem in respect to the motors and/or blower wheels. If the furnace did not make this noise previously I would suggest that you have a qualified HVAC technician inspect your system to prevent any possible damage in the future.
