  2. Disinfect Blower Wheel in-place?

    After vacuum cleaning the blower wheel in-place, can you disinfect it by spraying a product such as vital oxide or Benefect on the wheel and letting it dry before starting up the system? Just concerned about any risk to the motor.
  3. Air Handler blower motor random start / stop

    HVAC
    Blower motor in air handler starts, runs 1 sec, stops. This happens every 5 or 10 minutes. There is no relay click from thermostat when this happens. When the thermostat does call the blower motor (relay click heard) the blower runs correctly for the full heat pump cycle.

  5. Blower Broke (ECM variable speed motor)

    HVAC
    Blower Motor on Rudd System stopped working after 8.5 years. First vendor said $810 parts and labor to replace motor assembly. Second quote was $300. Why the disparity? The Motor-Cap has the electronics like the "start capacitor". Only needed to replace the motor-cap not the motor. Saved me...

    HVAC
    Hi everyone, After receiving some rather outrageous prices from a local HVAC place, I've decided to fix my parent's HVAC on my own. I've repaired a number of appliances and work with computers, so while I'm no expert on HVAC, I'm not an idiot at dealing with things like this. The repair guy...

    I hear a lot of blower noise in my living room. When I moved in, I got an HVAC contractor to add AC to the existing forced air heat system, and he said the problem is that the return air duct is just too short. Houses around here (1950s neighborhood, San Francisco Bay area) didn't originally...
