When Is It Time to Replace Your AC Unit?

Not sure whether your air conditioner needs a repair or a full replacement? Here are the most common signs that it may be time to upgrade:

✔ Your AC is 10–15 years old or older – Aging systems become less efficient and more prone to breakdowns.
✔ You’re scheduling frequent repairs – Ongoing service calls add up quickly; a new system may cost less over time.
✔ Uneven or insufficient cooling – If some rooms stay warm or airflow is weak, your system may be on its last leg.
✔ Energy bills are rising – A sudden or steady increase in utility costs often means your system is working too hard.
✔ Your system still uses R-22 refrigerant – This type is outdated and expensive to replace due to environmental restrictions.
✔ The AC can’t keep up in hot weather – Struggling to maintain comfort on warmer days signals declining performance.

Our HVAC specialists in Philadelphia can help you determine if a replacement is necessary — and recommend the right system for your space and budget.
