AC Repair vs. Replacement in Los Angeles — How to Decide

Quick answer: Repair your AC if it’s under 10 years old and the repair costs less than 30% of a new system. Replace it if it’s over 12–15 years old, uses R-22 refrigerant, or you’re facing a second major repair within 2 years. A typical AC repair in Los Angeles runs $150–$1,500; a full replacement runs $6,000–$18,000. APLA Construction (CA Lic #1136359) provides free diagnostic visits across Greater Los Angeles.

AC Repair vs. Replacement in Los Angeles — How to Decide

Every LA summer, the same question comes up: is it worth fixing the old AC one more time, or is this the year to replace it? The right call depends on the system’s age, refrigerant type, repair history, and how the numbers stack up — not just what breaks today.

The 50% Rule (and Why It’s Not the Whole Story)

A common rule of thumb: multiply the system’s age by the repair cost. If that number exceeds half the cost of a new system, replace it. It’s a reasonable starting point, but three factors in Los Angeles specifically push the decision toward replacement earlier than the rule alone suggests:

• R-22 refrigerant systems. Older units (roughly pre-2010) use R-22 (“Freon”), which the EPA phased out of new US production and import as of January 1, 2020, under the Clean Air Act. If your system needs a refrigerant recharge and it’s R-22, that alone can cost $600–$1,000/lb for existing stockpiled refrigerant — often more than the repair would cost with modern R-410A.
• Efficiency gap. A 15-year-old AC running at SEER 10–12 costs meaningfully more to run through LA’s long cooling season than a modern SEER 16+ system. Utility savings partially offset replacement cost over time.
• Rebate eligibility. Heat pump replacements can qualify for state and utility rebates (see below) — money that’s only available if you replace, not repair.

Signs You Should Repair, Not Replace

• System is under 10 years old
• This is the first significant repair in several years
• The specific failure is isolated — a capacitor, contactor, or fan motor, not the compressor
• Uses standard R-410A refrigerant (post-2010 systems)
• Energy bills haven’t meaningfully increased

Signs You Should Replace

• System is 12–15+ years old
• Uses R-22 refrigerant
• This is a second major repair within 2 years
• The compressor has failed (often 40–50% of a full system’s cost to replace alone)
• Energy bills have risen noticeably without a change in usage
• You’re renovating anyway and can size a new system correctly for updated square footage

Typical AC Repair Costs in Los Angeles (2026)

Repair	Typical Cost
Capacitor replacement	$150–$400
Contactor replacement	$150–$350
Fan motor replacement	$400–$900
Refrigerant leak repair + recharge (R-410A)	$400–$1,200
Refrigerant recharge (R-22, legacy systems)	$800–$2,500+
Compressor replacement	$1,800–$3,500

The Real Cost of “Just One More Repair”

The most expensive path is often a string of smaller repairs on an aging system — $400 here, $600 there — that together approach or exceed the cost difference toward a new, more efficient system, without ever getting the efficiency or rebate benefit of replacing. If a licensed technician tells you the compressor has failed on a system already past 12 years old, that’s almost always the point to replace rather than repair.

Frequently Asked Questions

How do I know if my AC problem is a repair or a sign of bigger issues?

A qualified diagnostic visit is the only reliable way to know. APLA provides free diagnostic estimates that identify the specific failure and give you honest repair-vs-replace guidance — not a sales push toward the more expensive option.

Is it worth repairing an R-22 system in Los Angeles?

Usually not for anything beyond a minor fix. R-22 is no longer manufactured in the US, so refrigerant costs have climbed sharply. If an R-22 system needs a refrigerant recharge, replacement is almost always the better financial decision.

Can I replace just the outdoor unit and keep my indoor coil?

Sometimes, but it’s often not recommended. Mismatched system age and efficiency ratings between old and new components can reduce performance and shorten the lifespan of the new unit. We evaluate compatibility during the estimate.

How long does an AC replacement take?

A straightforward replacement with existing, usable ductwork typically takes 1–3 days. See our HVAC contractor page for the full range of installation timelines by system type.

Do you offer financing for AC replacement?

We can discuss project financing options as part of your estimate. Call to talk through what fits your budget and timeline.
