How to Fix Your Broken AC

Test your thermostat for problems

Try the thermostat at the lowest setting. If the AC doesn’t work, the thermostat may need recalibrating. Check with the manual or a specialist.

Clear out the drain tube

Check regularly for water pooling around your air conditioning unit. The condensate drain is likely blocked - clean with chemical tablets.

Carefully clean the fins

Clean the fins to improve your AC’s efficiency. Use a soft-bristle brush on the fins - be gentle when cleaning to avoid causing damage.

Adjust any damaged fins

If you find broken fins, these can be adjusted with subtle pressure from a kitchen knife. Again, go gently or the fins might break.

Add a new layer of insulation

Repair the insulation around your outdoor AC tubes if unhappy with efficiency. Remove any damaged insulation foam and replace with a new layer.
