Fan speed low...


Wondering what are some common reasons for the HVAC blower to only run at a very low speed.

Unit (heat pump) does heat and cool, but just recently the blower speed is very, very low.

Filters changed, A coil is clean, programmable thermostat seems to be working normally.

although depending on the unit heat is run at a slower speed than cooling and heatpump speed is slower than emergency heat speed.
if it is a multispeed airhandler speed changes are timed and specific
