FAQ

AC Repair & Replacement — Frequently Asked Questions

Have questions about AC service? We have answers.

How do I know if my AC needs repair or replacement?

If your AC is under 10 years old and the repair cost is less than half the cost of a new system, repair is usually the better choice. If your system is over 12-15 years old, requires R-22 refrigerant, or repair costs approach a new system, replacement is often smarter. We'll give you an honest assessment either way.
