It's close. A diagnostic plus a free replacement quote lets you compare side by side.
- Age × repair cost is $9,600 — over the $5,000 line where replacement is usually worth pricing.
- At 12 years it's in the typical 12–15 year end-of-life window.
A rule of thumb, not a diagnosis. Your technician will confirm what's actually going on before anything is decided.
How we think about it
What is the $5,000 rule for HVAC?
Multiply the age of your system by the repair cost. If the answer is over 5,000, replacing usually makes more financial sense than repairing. A 12-year-old AC with a $500 repair scores 6,000 — worth pricing a replacement before you decide.
How long does an AC or furnace last in Oklahoma?
Central air conditioners and heat pumps typically last about 12 to 15 years, and long, hot Oklahoma summers push many toward the low end. Gas furnaces usually last 15 to 20 years. Regular maintenance helps a system reach the high end of its range.
Should I repair an R-22 system?
R-22 refrigerant is no longer produced or imported in the United States, so recharging an older R-22 system costs more every year. A small repair can still make sense, but if it needs refrigerant, it is usually time to price a new system.
What does a diagnostic visit cost?
A diagnostic visit is $95, and it is waived when you go ahead with the repair. Estimates for a replacement system are free.
