Everything is working fine- heating and cooling, but we continue to hear a humming noise throughout the house, especially in the morning hours.

starstarstarstarstar 		Mitsubishi MSZ-GE60VA heatpump HUM
by: Richard

We get a hum that comes into the room from the Mitsubishi MSZ-GE60VA heat pump. Didn't get it with the previous Daikin pump (12 years older). Installer says it's normal but this is not acceptable from Mitsubishi company that advertises as the quietest pumps. Still trying to get the supplier to stand by their word that the Mitsubishi pump will be quieter than our old Daiken

I have the same problem as K in Woodbridge:

Everything is working fine- heating and cooling, but we continue to hear a humming noise throughout the house, especially in the morning hours.

Have not seen an answer to this problem and our HVAC folks seem puzzled too.
