What's in an annual tune-up
A standard AC tune-up costs $80–$200 and includes: refrigerant level check, condenser coil cleaning, evaporator coil inspection (if accessible), capacitor + contactor test, blower motor amp draw check, thermostat calibration check, condensate drain clear, and a basic safety/electrical inspection. Most pros offer a "club membership" annual service for $150-$300/year that includes one spring + one fall visit + 10-15% off any repair. Worth it if your system is 5+ years old.
Common repair costs
Capacitor — the small cylinder that gives the compressor + fan motors their starting kick. Most common AC failure on systems 8+ years old. $150-$300 to replace (parts + labor). Contactor — the relay that turns the compressor on/off. $150-$300. Condenser fan motor — the motor that drives the outdoor unit's fan. $300-$700. Blower motor — moves air through the indoor coil + ductwork. $400-$900. Refrigerant recharge — only valid if the system has been leak-tested first; pure top-off with no leak repair just delays the next failure. $200-$700 depending on refrigerant type (R-22 phaseout makes that refrigerant 3-5x more expensive than R-410A; older systems running R-22 are often replacement candidates).
When repair vs replacement
Three repair-vs-replace heuristics. (1) Age — AC systems average 12-18 year lifespan. Past 12 years, replacement starts becoming economic. (2) The 50% rule — if a single repair costs more than 50% of a new system's price, replace. (3) R-22 refrigerant — if your system uses R-22 (anything before ~2010 typically), replacement is usually cheaper than recharging given R-22's post-phaseout price. Modern replacements use R-410A and (newer 2025+) R-32 / R-454B refrigerants.
Full system replacement
Central AC replacement for a typical 2,000 sq ft home (3-ton system) runs $4,500-$8,000 installed. Variables: SEER rating (14-16 SEER is the entry level; 18-20 SEER costs $1,000-$2,500 more but uses 25-40% less electricity), brand (Trane, Carrier, Lennox at the top end; Goodman, Rheem in the value tier), and ductwork condition (poor existing ducts can add $500-$2,500 to fix as part of a system swap). The IRA 25C tax credit covers 30% of high-efficiency heat pump replacement costs up to $2,000/year. If you're considering replacement, heat-pump-instead-of-AC is a strong option for most US climates — same cooling, plus heating in winter, often qualifies for the larger $2,000 credit.
Emergency rates + service call fees
Same-day repair calls in summer peak (July-August in most US climates) run 1.5-2x the standard rate + a $100-$200 service-call fee. Off-season repairs (October-March): standard rates, often with discounts. Schedule the annual tune-up in March-April before the seasonal price hike.
Maintenance you can do
Owner-side AC maintenance that prevents most repair calls: (1) Replace air filter every 1-3 months — $5-$30 per filter, biggest single thing for system health. (2) Clear vegetation 2 feet around the outdoor condenser unit. (3) Hose off the condenser fins gently 2-3x per cooling season. (4) Make sure the indoor air return isn't blocked by furniture. (5) Set thermostat to "auto" not "on" for the fan — saves the blower motor. Skipping these basics dramatically shortens system life.

How often should I get my AC tuned up? ▾
Annually, ideally in spring before peak cooling. Skipping the tune-up shortens system life + voids many manufacturer warranties.
Why is my AC blowing warm air? ▾
Five common causes: (1) tripped breaker, (2) clogged air filter, (3) dirty condenser coils, (4) low refrigerant from a leak, (5) failed capacitor. First three are owner-fixable; latter two need a pro.
How long does an AC last? ▾
12-18 years average. Coastal/salt environments shorten this to 8-12 years. Past 15 years, repairs start losing economic logic vs replacement.
Should I repair or replace a 12-year-old AC? ▾
Apply the 50% rule: if the repair quote is over 50% of a new system's price, replace. Also consider R-22 vs R-410A — R-22 systems are usually replacement candidates because the refrigerant cost makes recharges expensive.
What's the AC tax credit for 2026? ▾
IRA 25C credit: 30% of cost up to $2,000/year for high-efficiency heat pumps, $600/year for AC alone. Energy Star Most Efficient certification typically required.
Why is R-22 refrigerant so expensive? ▾
R-22 was phased out for new systems in 2010 + new production was banned in 2020; only stockpiled supply remains. Prices have risen 3-5x; recharging an R-22 system is rarely economic.
How much electricity does a central AC use? ▾
A 14-SEER 3-ton system uses ~3 kWh/hr running. At $0.15/kWh that's $0.45/hr, or ~$135/month at 10 hrs/day operation. Higher SEER (18+) cuts that 20-30%.
Does AC replacement need a permit? ▾
Most jurisdictions: yes, especially when refrigerant lines or electrical disconnect are involved. Reputable HVAC contractors pull the permit and itemize the cost on the invoice.
