In Maine's very cold climate: central AC typically lasts 15–20 years, gas furnaces 20–30 years, and heat pumps 15–20 years. With regular annual maintenance, Maine homeowners commonly see systems reach the upper end of these ranges.
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 Maine, getting a replacement quote alongside a repair quote is always worthwhile — contractors in the state average 9,604 for full replacement.
