3 Warning Signs of a Failing AC

To help you determine if you need a new cooling system, consider these indicators:

Old air conditioners are considerably less efficient compared to new models, which means they use more fuel to cool your home. If you notice a hike in your electricity bills without a comparable change in your cooling habits, an inefficient AC could be the culprit.

Old cooling systems experience the most issues during the last 2 years of their life, so, if you notice an increasing number of visits from your local AC technician, it may be time to switch to a new air conditioner.

If you notice some rooms are cooler than others, it means your existing air conditioner is no longer able to evenly distribute cool air. While it may be a duct issue, but you can’t negate the possibility that your AC is already deteriorating, especially if it’s more than a decade old.
