Before you call a repairman there are a few things you can do.

The first thing you should do is check to see if your air filter is dirty and if it is, replace it and see if that helps.

The next thing to do is go outside and look at the outdoor air conditioner component.

Is the outdoor unit running?

If not, check the circuit breaker – if it’s tripped, try resetting it.

Make sure the thermostat setting is correct.

If the unit is running..

The next thing to do is inspect the unit.

Is there dirt or debris on the coil section? If so, turn off the circuit breaker for the unit and spray down the coil with a garden hose (be careful not to bend the coil fins) until it’s clean, then turn on the breaker.

If the coil is clean, look at the copper lines that are attached to the unit – the small line is bare copper and the larger line will usually have black insulation covering it.

Do you see any ice or frost on the larger line?
