Why is my unit freezing up?

There are several things that can freeze up your coil and / or reduce air flow. Anything that restricts the airflow through the inside unit will cause frost. As the frost builds up on the coil, the airflow becomes more and more restricted making the condition worse.

1. Extremely dirty air filter restricting the airflow through the inside unit.

2. System low on freon, causing coil to freeze up.

3. Check your return grill to make sure that it is not being obstructed.

4. Blower motor overheats and "kicks off" on safety switch.

When freezing up occurs on the outside pipes next to the compressor, you have a situation where damage to the compressor can occur.

There's water spilling out of my inside unit, what can I do about this?

If you do not see ice build up on the copper tubing when you run your system, then you probably have a clogged drain line. A clogged drain line is usually caused by dust or algae build-up inside the drain line.

The system is running but the air is not very cold?

If some cooling is taking place but not enough, then the chances are that the system is low on freon. The only reason a system would need freon is because the freon leaked out.

1. Dirty indoor air filter.

2. Possible low freon.

3. Condensor coil dirty.

4. Compressor to outdoor unit is not running for some reason.

5. Possible lose return air duct.
