Here’s what you should do at least once a year:
- Remove lint from the dryer vents. Be sure to service the ducts all the way to the vent outlet. You should also clean the lint trap before or after each use.
- Clean dirt and ice from refrigeration coils on all appliances that have them.
- Replace the filters in your refrigerator, dryer, washer, and air circulation system.
It’s also a good idea to keep a maintenance record for all your appliances. It will come in handy for making a quick diagnosis if something major goes wrong.
