How to save money on cooling costs Common problems...

Dirty filters start a chain reaction that take out other components down the line.

The dirty outside causes the motor to run hotter and shorten its life span.

The real problem is that these blades are full of dirt. They are now flat across instead of cupped. These are just beating the air, not pushing it. This unit will have to run for hours trying to move the air it could move in minutes if it were clean.

We have seen furry motors like this one get so hot, the wires melt and actually catch fire inside the furnace.

The outside of this coil looks great. It has a plastic pan and won't rust. The outside is clean and all the fins are shiny with no rust in sight.

The inside is where it matters, and this coil is actually completely stopped up. Not one of the fins is visible. The air is being blocked where it should be free flowing across the coils. This is a result of running a unit without a filter or not changing the filters often enough. Dirty coils (both inside and outside) cause a unit's airflow and efficiency to plummet.

This coil has a metal pan and is rusted out. Water was leaking all over the closet and down the hallway floor. Again the outside is shiny, but lets look underneath.

This is the bottom of the same double "A" coil and both sides are completely stopped up. Some of the layer of filth has been removed to show the fins underneath that should be visible on the entire unit.

This is the most dangerous and potentially deadly situation of all. A cracked heat exchanger can act like a forge, blowing flames around the furnace.

If the heat exchanger has any cracks at all, even a small one, the poison gases will be drawn into the inside air.
