Insulation was sucked up into the blower wheel.

Can you see the door to the closet where the A/C air handler is located?   Of course you have to move things out of the way to get in there, but when space is at a premium …. not a bad idea.

This refrigerant line was pinched by the installer … no wonder the system never cooled very well.

This refrigerant screen was so clogged the system stopped cooling … usually a sign of poor installation quality.

Not the right way to vent a condensing furnace, but have to hand it to the installer for being creative.

Can only guess that the installing contractor ran out of the right sized copper … using a smaller size limits capacity and efficiency.

This indoor coil generated a 30-pound block of ice  (usually a result of low refrigerant or restricted air flow).

The cabinet insulation peeled off the side and got struck in the blower wheel.

An unlicensed “friend” installed this furnace for a client and nearly burned his house down. In addition to improper valve conversion (natural gas -> propane), the electrical is exposed and the gas flex line is run through the furnace cabinet.

Proper application of radiant barrier (don’t go with the spray on type).
