Should I Repair or Replace My Air Conditioner?

The Decision Framework: One Simple Test

Multiply the repair cost by the system’s age in years. Cost depends on the system and the repair; we give you a written quote before work starts.

This isn’t a perfect formula, but it gives you a rational starting point that removes emotion from a decision most homeowners face in the worst possible moment: when it’s 98°F outside and their AC just stopped.

When Repair Makes Sense

The system is under 10 years old. Modern AC systems are designed for 12–15+ years of service life with proper maintenance. A 7-year-old system with a failed capacitor, a refrigerant leak, or a dirty coil is a repair, not a replacement.

The repair is a single, isolated component. Capacitors, contactors, fan motors, and refrigerant recharge are all common repairs that restore a system to good working order. These aren’t signs that the system is failing — they’re normal maintenance-level events.

The system has been well-maintained. A system with an annual tune-up history and clean filter records is a different animal than one that’s been ignored for a decade. Maintenance history matters when evaluating remaining life.

When Replacement Makes More Sense

The system is 12–15+ years old. In the Dallas climate — systems running 8–12 hours a day from June through September — age catches up faster than in milder climates. At 15 years, the honest conversation is about when, not if.

The compressor has failed. Cost depends on the system and the repair; we give you a written quote before work starts. On a system under warranty, replacing it makes sense. On a 10+ year old system out of warranty, that cost approaches new-system territory without the efficiency gains.

You’re running R-22 refrigerant. R-22 (Freon) was phased out of production. Recharging an older R-22 system is expensive and only delays the inevitable. If your system requires R-22 and has a refrigerant leak, replacement planning should start now.

Energy bills are rising without explanation. An older system working harder than it used to — drawing more electricity to maintain the same temperature — is telling you something. The efficiency gap between a 14-SEER system from 2010 and a 16-18 SEER2 system today translates to real money over a Dallas summer.

You’re repairing it repeatedly. One repair a year is normal. Two in a season, or three in two years, is a pattern. Each repair has a cost, but the accumulation also represents a system in general decline.

The Compressor Question

Cost depends on the system and the repair; we give you a written quote before work starts. The gap between those numbers is often smaller than it looks when you account for lower energy bills on the new system.

We tell customers this even when the repair is the higher-margin job for us. A customer who trusts the advice is worth more than the service call.

What About System Sizing?

One thing most repair-vs-replace conversations skip: if your current system was improperly sized — too large or too small for your home — replacement is an opportunity to fix that problem, not just repeat it.

An oversized system short-cycles. It cools the space fast, shuts off, and never runs long enough to manage humidity. A Dallas home with an oversized AC unit feels cold and clammy at the same time. Replacing the same size doesn’t fix the comfort problem.

When we do a replacement assessment, we run a Manual J load calculation to size the new system for your home’s actual heating and cooling load — not just the square footage.
