Common questions
Most common causes: dirty air filter (check first — free), low refrigerant, a failed capacitor, or an undersized unit for the space. Filter is a 5-minute DIY fix.
Diagnostic visit: $85–$150. Capacitor replacement: $150–$300. Refrigerant recharge: $250–$600. Full unit replacement: $4,500–$12,000.
If the unit is under 10 years old and the repair is under 50% of replacement cost, repair. Over 15 years old with a major failure — replace.
