When Should You Replace Your AC?

Know the Signs Before You’re Stuck in the Heat

Not sure if you need a new air conditioner? Most homeowners aren’t – until the unit finally quits in the middle of a heatwave.

But you can avoid emergency breakdowns by watching for these signs that your system is on its last legs:

Your system is 12–17 years old: Most AC units in New Jersey climates start to lose efficiency after 10–15 years, even with good maintenance.
Rising energy bills: Older systems tend to run longer and harder to cool your home, which drives up your monthly costs.
Uneven cooling or weak airflow: If some rooms are hotter than others, or you barely feel air from the vents, your system may be too small or failing.
Frequent breakdowns or repairs: If you’ve had to call for AC service more than once or twice in a season, a replacement could save you money long-term.
Your system uses R-22 refrigerant: If your unit was installed before 2010, it may use outdated refrigerant that’s now expensive and being phased out.

Don’t wait until your system completely fails. A proactive replacement can save you money, improve comfort, and give you peace of mind all summer long.
