When to repair, when to replace, and how to use the 5000 Rule to make the right call every time.
Actual contractor pricing for every common AC repair - capacitors, refrigerant, compressors, and more.
The complete maintenance calendar for every HVAC unit type. Includes DIY tasks and what to leave to professionals.
Our figures are estimates based on typical national price ranges for common repairs, adjusted by a regional labor-cost multiplier. They are not quotes and not a survey of contractors, and actual prices can differ substantially. 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.
