In New Mexico's hot dry climate: central AC typically lasts 15–20 years, gas furnaces 20–30 years, and heat pumps 15–20 years. Heavy cooling loads can shorten AC lifespan to 12–15 years without regular maintenance. Annual tune-ups and coil cleaning are especially important in New Mexico.
Use the "$5,000 Rule": multiply the unit's age (years) by the repair cost. If the result exceeds $5,000, replacement typically makes more sense financially. Example: a 12-year-old unit needing a $500 repair = 12 × $500 = $6,000 — lean toward replacement. Also replace when: (1) AC is 15+ years old or furnace is 20+ years; (2) repair cost exceeds 50% of replacement cost; (3) R-22 refrigerant is involved (discontinued, now $150+/lb to recharge); (4) energy bills have risen 20%+ without explanation. In New Mexico, getting a replacement quote alongside a repair quote is always worthwhile — contractors in the state average 8,820 for full replacement.
