Quick answer: If your AC has failed completely in Houston heat, call +1 (254) 256-1678 now. The line is answered 7:00 AM – 9:00 PM CT, 7 days a week. You get an honest arrival window, the after-hours price before anyone drives out, and a technician who carries the parts that fail most often — capacitors, contactors, fan motors and drain components — on the truck.
What counts as an AC emergency
- Total cooling loss during a heat wave. With outdoor temperatures above 95°F, indoor temperatures climb fast. If anyone in the home is elderly, an infant, or has a medical condition, treat it as an emergency.
- Water coming through the ceiling. Attic-mounted air handlers — standard in Houston homes — can dump gallons of condensate through drywall when the drain clogs or the pan fails. Shut the system off and call.
- Burning or electrical smells. Turn the system off at the breaker. A failing motor or wiring fault is a fire risk, not a comfort issue.
- Breaker trips instantly when the AC starts. Usually a shorted compressor or a hard electrical fault. Do not keep resetting it.
- Ice covering the refrigerant lines or the indoor coil. Running a frozen system destroys compressors. Turn it off, let it thaw, call for service.
What to do before the technician arrives
- Turn the system off at the thermostat if you see ice, water or smell burning.
- If water is leaking, move furniture and put a bucket or towels under the drip.
- Check the air filter and the thermostat batteries — two five-minute fixes that solve a surprising number of "emergencies."
- Close blinds, run ceiling fans, and keep everyone in the coolest part of the house.
- Have the gate unlocked and the path to the air handler and outdoor unit clear.
Honest hours and after-hours pricing
We do not advertise "24/7" we cannot staff. The dispatch line is answered 7:00 AM – 9:00 PM CT, 7 days a week — when you call, you hear immediately whether a technician can reach you tonight or first thing in the morning. After-hours and weekend visits carry a surcharge, typically $100–$300 on top of the diagnostic fee, and you hear that number before anyone is dispatched. No "technician is 10 minutes away" scripts, no surprise fees on the invoice.
The failures we see most on emergency calls
Emergency calls in Houston cluster around a short list of parts, and trucks are stocked accordingly: failed capacitors and contactors after heat waves, condenser fan motors that seize in July and August, clogged condensate drains during humid stretches, and compressors that finally give out after weeks of short cycling. Most emergency repairs are single-part jobs finished in one to two hours once the technician is on site.

Frequently asked questions
What counts as an AC emergency in Houston?
A total loss of cooling during a heat wave (especially with elderly people, infants or medical needs in the home), water actively leaking through a ceiling from an attic air handler, a burning or electrical smell from the equipment, or a breaker that trips the moment the AC starts. Warm air alone on a mild evening can usually wait for a regular appointment.
Are HVAC technicians really available 24 hours in Houston?
Some companies staff overnight on-call technicians; others answer phones around the clock but dispatch in the morning. Our phone line is answered 7:00 AM–9:00 PM CT daily — when you call, you hear immediately whether a technician can reach you tonight or first thing tomorrow. We do not promise 24/7 dispatch we cannot staff.
How much does emergency AC repair cost in Houston?
After-hours calls typically add a $100–$300 surcharge on top of the diagnostic fee and repair. A nighttime capacitor replacement usually totals $250–$600; a fan motor $350–$900. You always hear the surcharge and the full repair price before approving the work.
What should I do while waiting for an emergency technician?
Turn the system off at the thermostat if you see ice on the lines, water leaking, or smell anything burning. Close blinds on sun-facing windows, use fans, and move anyone heat-sensitive to the coolest room. Do not keep resetting a tripping breaker — that is a hard fault, and repeated resets can destroy the compressor.
Is a broken AC in Houston actually dangerous?
It can be. Indoor temperatures in a closed Houston home can pass 90°F within hours on a 100°F day, and heat index values above 105°F are common. For infants, elderly residents and people with heart or respiratory conditions, loss of cooling during a heat wave is a genuine health emergency — treat it like one.
Which areas get the fastest emergency response?
Inner-loop and near-loop areas like The Heights see the shortest drive times. Katy, Sugar Land, Cypress, Spring, Pearland and Pasadena are all within normal dispatch range; The Woodlands is the far edge at 35–50 minutes in typical traffic. Call and you will get an honest arrival window for your address.
