An air conditioner will not run smoothly forever. Every electro-mechanical system runs into trouble at some point—but there are ways to prevent this. Regularly changing the air filter, for example, helps to regulate airflow, and without a clean filter your air conditioner could run into a number of problems throughout the season.
And perhaps the most important step in preventing air conditioner damage and improving efficiency throughout the summer is scheduling a tune-up. A professional AC tune-up is something we think any home with a central air conditioner should have done annually. But this late into the season, is it worth it to skip the tune-up? Can you or should you have one right now?
