As already stated: Blower squirrel cage and motor (one unit) are 6 months old and I pulled the service cover to see that it is running fine.
The air flow I am referring to is what comes out the vents.
If the coil is icing up, wouldn't I see it somewhere on the coils around the unit?
Lastly, why would it run better after I shut the unit down for 15-30 minutes?
To make matters more confusing: last night it started working fine and has been OK ever since. This is the 4th time its done it (and then the problem went away) in 2 weeks so I'm ready to pay the HVAC dude but the guy I use for the last 20 years is out till Monday. I would rather wait since I have tried 2 other companies and been cheated, overcharged, and had shabby work.
In the meantime, thanks for the group problem solving session. Any other ideas between now and Monday?
