Signs It's Time for a New AC

A properly sized, properly installed AC will run efficiently for years. Here's when replacement makes more sense than another repair:

AC Is 12–15+ Years Old
Most central AC systems last 12–15 years. After that, efficiency drops and breakdowns become more frequent and more expensive.
System Uses R-22 Refrigerant
R-22 is no longer manufactured. If your system needs a refrigerant charge, replacement is usually the smarter long-term investment.
Repair Costs Keep Adding Up
When a repair approaches half the cost of a new unit, replacement typically makes more financial sense over the next few years.
Running Constantly, Still Not Cooling
An AC that runs all day without getting the house comfortable is working too hard — and costing you on every electric bill.
Humidity Feels Out of Control
A properly sized AC controls humidity, not just temperature. A muggy house even when the AC is running often points to a sizing or age issue.
Breaking Down Every Season
Recurring repairs mean the system is at end of life, not just having a bad year. At some point, you're spending more than a new unit would cost.

"My AC unit died on a Sunday. Mark called me back the same day when they weren't even open. Quoted a fair price to replace the unit — in fact it was the best quote I got. The install was done quickly and correctly."

"He came out within 2 hours of my call. New unit was installed the next day. They didn't try to oversell me something more expensive or larger than I really needed. Went over everything they installed."
