Clean air conditioner before spring

Clean air conditioner before spring


Cleaning your air conditioning unit is an easy task but one that many people overlook.

A clean air conditioner works more efficiently, costs less to operate and is less likely to require repair. Setting up a schedule for regular cleaning is a good maintenance practice, and one of the best times is now, before the season begins.

Tools, materials needed

1. Vacuum cleaner or shop vac

2. Garden hose

3. Screwdriver, pliers

4. HVAC cleaner (available in spray cans at hardware stores)

5. Shop cloth or soft bristle brush (such as an old toilet brush)

Instructions

Window air conditioner

1. Unplug the power cord from the outlet

2. Remove the filter cover on the inside of the house

4. Vacuum all of the dust and dirt from the unit that you can reach from the inside, and then go outside.

6. Remove the outside cover, spraying the inside of the cover with HVAC solvent and rinsing it clean with water from the garden hose.

8. Spray the compressor unit with the HVAC solvent and let sit for a few minutes. Clean the coils with the cloth or brush. Vacuum once more to get any dust or dirt that was missed.

9. Replace the cover
