Another HVAC Question

Turned on the heaters in the house today. One worked fine, not sure about the other. The one I am not sure about it kicks on but takes a few minutes before it is really pulling air through the return. When it initially comes on it is barely pulling air through the return. When the other comes on it is pulling air through the return immediately. Any suggestions/ideas?

Change the filter, if that does not help look for a crushed duct/ducts on either discharge or return or possibly some connection came apart on return side.
Many other options but these are the most likely as well as easiest to cure.

A thought: has the blower been acting up in any other ways lately?
Can you make it spin at high speed by setting the fan switch to "on" at the t-stat?
I've seen blower motors have some damage in the windings that don't allow for appropriate speeds.
Maybe also try putting a fresh capacitor in the blower motor.
Good luck.

I had a similar issue. My CO vacuum valve was stopped up, gas heat, and it was not allowing the blower to engage.

First question is did you notice reduced flow when set on cool? Same blowers... Check on cool again and see if there is a difference

Are they the same age and/or same model? Newer heaters will take a couple of minutes to warm up before the blower kicks on so that the blower doesn't start blowing cold air at the start.
