I know this is a shot in a million but its worth a try since my repair guy can't get here til Monday.
8 Yr Old Lennox heat pump HVAC. Plenty big for my house (as per HVAC repair dude). New squirrel cage last summer. Recharged refrigerant last winter (a had line was rubbing and over time leaked). Has been running perfectly until recently. Out of nowhere, the volume of air coming out the vents is almost nil. The coils are not frozen, there are no obstructions around the outside, everything sounds normal, I took the cover off the unit and the fan is running fine but there's very little air coming in and its not ice cold. If I shut the unit down at the fuse box and let it sit for a while it seems to come back but then later it starts slowing down. If I shut the unit down for just a minute, it takes longer than usual for the unit to kick in and the flow is the same. It sounds exactly like a frozen unit but there is no frost or ice anywhere. Suggestions?
