Our estimates are based on aggregated contractor pricing data from across the US, adjusted by city-level labor indexes. They're accurate within 15-25% for most repairs. Always get 2-3 quotes from licensed contractors before proceeding with major work.
Use the 5000 Rule: multiply your unit's age by the estimated repair cost. If the result exceeds the cost of a new unit, replacement is usually the better long-term investment. Our Repair vs Replace Calculator automates this and adds energy cost analysis.
A simplified rule is 20 BTU per square foot, adjusted for climate, ceiling height, insulation, and windows. Our AC Sizing Calculator handles all adjustments automatically. For a new installation, always have a certified technician perform a full Manual J calculation.
R-22 (Freon) was phased out under the Montreal Protocol and production was banned in the US as of January 1, 2020. Only recycled R-22 is available now, and supply is rapidly shrinking - driving prices from $5/lb in 2010 to $30-$175/lb today. If your unit uses R-22, replacement is usually more cost-effective than recharging.
Most HVAC systems should be professionally serviced once a year - air conditioners in spring, furnaces in fall. Units older than 10 years benefit from twice-yearly service. Monthly filter changes are the single most important maintenance task homeowners can do themselves.
AC repair costs average $150-$750 nationally, with most homeowners paying around $350. Common repairs like capacitor replacement run $100-$400. Major repairs like compressor replacement cost $800-$3,000. Costs vary significantly by city - use our calculator for city-specific estimates.
