How much does AC repair actually cost in Houston?
Most Houston AC repairs land between $150 and $900 all-in, flat rate. The spread comes down to the part that failed and the size of your system. A start capacitor is typically $150 to $350, a contactor $120 to $250, a condenser fan motor $300 to $550, a blower motor $500 to $900, and a full refrigerant leak repair $450 to $1,500 depending on how much refrigerant is needed. Every one of these is quoted as one fixed price before any work begins.
AC repair cost by part (2026 Houston prices)
Here's the honest table we show customers. Start capacitor: $150–$350. Contactor: $120–$250. Condenser fan motor: $300–$550. Blower motor: $500–$900. Evaporator coil (leak): $900–$2,400. Thermostat (installed): $200–$500. Condensate drain clearing: $120–$250. Compressor: $2,500–$4,500. Refrigerant leak: $450–$1,500. Prices are parts + labor, flat-rate, with a diagnostic fee that's waived when you approve the repair.
Why Houston AC repair costs what it does
Houston runs air conditioning almost year-round, which wears out capacitors and fan motors faster than in cooler climate cities. Demand also spikes in summer, and emergency calls on a 100-degree day cost a bit more than a scheduled visit. A flat-rate model protects you from the 'while I'm here' upsells and the hourly meter that rewards slow work.
Repair vs. replace: the cost math that saves you money
The rule we apply: repair if the system is under 8–10 years old and the failed part is a component, because those repairs pay for themselves many times over. Replace if the system is over 10 years old, still uses R-22, or the compressor has failed — at that point a $4,500 compressor into an aging system is often worse than a new $6,000–$14,000 system with a full warranty and better efficiency.
Frequently Asked Questions
How much does a capacitor replacement cost?
A start capacitor is typically $150–$350 installed in Houston, flat rate. It's the single most common AC repair and usually takes under an hour.
Is it cheaper to repair or replace my AC?
Repair when it's a component under $1,000 on a system under 10 years old. Replace when it's a compressor on a 10+ year old system, since that $2,500–$4,500 repair rarely makes sense in that case.
Do you charge by the hour?
No. Every repair is quoted as one flat price for parts and labor before we start. There's no hourly meter, and the diagnostic fee is waived when you approve the repair.
How much is emergency AC repair at night?
Parts are the same flat rate as daytime; labor carries a modest after-hours premium quoted on the phone before dispatch. A typical overnight capacitor repair is $150–$350 all-in.
