Repair or Replace? How to Tell When Your HVAC System Is Done

This is the question we get asked most on service calls, and it’s the one where an honest answer matters most — because the wrong call wastes your money either way. Here’s how we think about it.

The $5,000 rule. Multiply the repair cost by the age of the system. Over $5,000? Replacement usually makes more sense. A $600 repair on a 9-year-old unit (5,400) leans replace. That same $600 on a 5-year-old unit (3,000) leans repair. It’s a rule of thumb, not gospel, but it keeps you honest.

Age matters. Most ACs and heat pumps last 12–15 years in North Carolina; furnaces 15–20. Past that, you’re on borrowed time — and every repair is a bet that nothing else major fails this season.

Frequency of breakdowns. One repair every few years is normal. Two or three service calls in a single season is your system telling you something. Add up a year’s worth of repair bills and compare it against replacement — the math surprises people.

Your energy bills. If your summer power bills have been climbing year over year with no change in usage, your system’s losing efficiency. A new 16-SEER system can cut cooling costs noticeably versus a 15-year-old 10-SEER unit. That monthly savings is part of the math.

Refrigerant type. If your old system runs on R-22 (Freon), listen up: R-22 was phased out and it’s expensive — sometimes $100+ a pound. A leak repair plus recharge on an R-22 system can cost more than the system’s worth. At that point, replacement isn’t a sales pitch, it’s arithmetic.

Our promise: we’ll run the numbers with you and give you our straight recommendation — repair or replace — even when the honest answer means a smaller ticket for us. Furnace replacements from $2,500, package units from $6,499, quoted upfront.
