Do this now: no AC in a San Antonio heat wave

1. Anyone confused, with hot red dry skin, a fast strong pulse or a temperature above 103 F? Ready.gov lists these as heat stroke signs: call 911.
2. Check the thermostat and the breaker for the outdoor unit before calling.
3. Run fans only while it is under 90 F indoors; the CDC says a fan can raise body temperature above that.
4. Need a cool place tonight? The CDC says to dial 2-1-1 to find air conditioning nearby.
5. Whole street dark? Report the outage to CPS Energy at (210) 353-HELP (4357). For a gas or electric emergency, call 1-800-870-1006.
6. Write down any error code, noise or ice on the lines; it helps the technician.

Is it an emergency? Who needs help tonight

A dead AC is an emergency when the house keeps heating up and someone inside is elderly, very young, pregnant or ill. If everyone is healthy and the house holds under 90 F, a morning appointment avoids the after-hours rate, which HomeAdvisor puts at $160 to $250 an hour against $75 to $150 regular. HomeGuide says emergency HVAC rates typically run double or triple the regular rate. See emergency HVAC repair for national after-hours pricing.
