End of Summer Air Conditioning Maintenance Tips

As our Minnesota summer comes to an end, you may believe that you don’t have to think about your air conditioner until next spring.

However, you don’t want to face unexpected problems next season, so at the end of each summer, take the time to check your air conditioner and make sure it is in good working order.

Here’s what to look at.

1. Observe your unit for any unusual sights, sounds or smells

Any moisture, such as condensation on the unit or drips around the tubing, are obviously a sign that your unit needs service.

But, odd smells can also be a sign of mildew and a leak you can’t see. If this moisture stays inside the unit all winter, the mildew will be worse next spring.

Check for any unusual rattling sounds too.

2. Clean the area around your outdoor unit

This is especially important if it is in a part of your yard that you don’t look at very often.

The greenery that looks so small in the spring can quickly grow into tall grasses or trailing vines that hamper the air flow around your unit.

Check the coils and if they look dusty, clean them gently with warm water.

3. Change the filter

Perhaps you made sure you had a clean new filter at the beginning of the season but now after a couple of months of regular use it is probably time to change it.

You should change your air conditioner filters about every three months, but if you have allergies it’s a good idea to change them every month.

4. Schedule a check-up

Preventative maintenance will save you time next year.
