How old is too old for an air conditioner?
Carrier says most AC systems last 10 to 15 years. ARS advises planning to replace a central air conditioner every 8 to 10 years. Heavy use, climate, maintenance history, and installation quality can shorten that lifespan.
What repair cost means it is time to replace?
A common rule of thumb is to replace an AC that is more than 10 to 12 years old if repairs would cost at least 50% of a new system. Another guideline uses 30% for units older than 10 years. Compare the repair quote against replacement pricing before you decide.
Why does El Paso's climate affect AC lifespan?
El Paso had 3,267 cooling degree days since January 1 in the National Weather Service climate summary. ARS notes that long, hot summers in the South mean far more runtime, which wears systems faster. A higher cooling load can make replacement the better value sooner.
What does a new AC replacement cost?
Carrier says replacing a central AC typically costs $3,000 to $15,000, depending on size, efficiency, and installation. HomeGuide lists standard replacement at $5,000 to $8,300 and high-efficiency systems at $14,000 or more installed. Permits commonly cost $100 to $250.
What to do next
- Note how often the unit has broken down in the past two years and how fast your cooling bills have risen.
- Ask the pro for the repair cost and the replacement cost side by side, so you can apply the 50% rule.
- Verify the contractor's Texas Air Conditioning and Refrigeration Contractor license on the Texas Department of Licensing and Regulation website.
- Ask the pro for proof of liability insurance and confirm the quote covers permits.
