Should You Repair or Replace Your AC?

Not sure whether to repair your current system or invest in a new one? Chapman Bros. helps you make the right call based on your specific situation — not on upselling. Use this framework as a starting point:

  • System age: If your AC is 12–15+ years old, replacement is usually more cost-effective than repeated repairs.
  • The 50% rule: If the repair cost exceeds 50% of the price of a new system, replacement is the smarter investment.
  • SEER rating: Older units often run at 8–10 SEER. Modern systems start at 14–16 SEER and high-efficiency models reach 20+ SEER — cutting cooling costs by 30–50%.
  • Frequent breakdowns: If you’re calling for repairs every season, a new system will save money and stress.
  • R-22 refrigerant: Systems using the now-phased-out R-22 refrigerant are increasingly expensive to service and should be replaced.

Still not sure? Our technicians will give you an honest assessment with no pressure. You can also start with an AC inspection or schedule a repair diagnostic to understand your options.

Frequently Asked Questions
How do I choose between the new SEER2 ratings?
As of 2023 and updated through 2026, the industry has shifted from SEER to SEER2 (Seasonal Energy Efficiency Ratio 2). This newer testing standard more accurately reflects real-world “static pressure” (how hard the unit has to push air through your vents). While a higher SEER2 rating—like a 18 or 20—costs more upfront, these units often feature Inverter Technology, allowing the compressor to run at variable speeds rather than just “on” or “off.” This results in significantly better humidity control and lower monthly electricity bills.
Yes, this is highly recommended for a “matched system.” Modern air conditioners use R-454B or R-32 refrigerants, which operate at different pressures than the older R-410A systems. If you try to pair a new high-efficiency outdoor unit with an old, dirty indoor coil, the system will not reach its rated efficiency and will likely suffer from premature compressor failure. Furthermore, a new indoor coil features a Thermal Expansion Valve (TXV) specifically calibrated to the new outdoor unit’s refrigerant flow, ensuring optimal cooling and dehumidification.
Technology and home insulation have improved over the decades. If your home has new windows or better attic insulation, your old 3-ton unit might now be oversized. An oversized AC is actually worse than an undersized one; it will “short-cycle,” cooling the air so fast that it never has time to remove the humidity, leaving your home feeling “cold and clammy.” A Manual J calculation takes into account your home’s orientation to the sun, wall thickness, and window types to determine the exact BTU capacity required for a comfortable, dry environment.
