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.

Anyone who has ever worked in a hot garage, in summer, in Florida knows that even a tiny hint of cold air is welcome relief! I wanted to try the project but didn't want to go to the expense and effort of ordering the needed styrofoam bucket liner that the project required. I was on the lookout for something that would eliminate the need for the liner. As luck would have it, I found this insulated vertical drink cooler that would be perfect for only $2 at a yard sale. I already had the needed plastic tubing, fan, and hole saw cutter so the expense for this project was minimal!
