The Decision Rule
If the repair is under 40 percent of a new system and the unit is under 10 years old, repair wins. Otherwise, replacement usually makes more sense. That's the whole rule — the rest is just applying it to your system.
At a Glance
Three rows, one recommendation. Where your system falls tells you which way to lean.
A reasonably young unit with a modest repair is almost always worth fixing.
At this age and cost, the math gets close. A straight-talk estimate helps you decide.
Past 15 years in Texas heat, a major repair is money into a system that's already on borrowed time.
DFW Units Age Faster
The national average for an AC system is around 20 years. In Dallas-Fort Worth, plan for 10–15 years instead. The reason is simple: Texas summers mean months of continuous running. A compressor that works hard through 100°F+ days cools harder, cycles more, and wears out sooner than the same unit in a milder climate.
That's why age matters more here than the sticker suggests. A 12-year-old unit in Dallas is not the same animal as a 12-year-old unit somewhere cooler — it's already lived a harder life.
When to repair
- •Under 10 years old
- •Repair under 40% of replacement cost
- •Still cools to setpoint without constant running
When to replace
- •Over 15 years old
- •Repair over 40% of replacement cost
- •Summer electric bill keeps climbing
The Real Payoff: Lower Summer Bills
If replacement is the call, the upside is real. Newer high-SEER systems run more efficiently than units from a decade ago — and many DFW homeowners see noticeably lower summer electric bills after upgrading. In a climate where the AC runs half the year, that adds up.
