HVAC in Houston: answer every call from May to October
Houston does not have a summer rush. It has a six-month season where the heat index sits above 100°F, systems run 14 hours a day and a Katy homeowner whose AC quit at 4pm is calling the next company by 4:10. Here is how Houston HVAC shops answer all of them.
What a HVAC company in Houston should set up first
An AI receptionist on your existing 713, 281, 832 or 346 number that books repairs into ServiceTitan or Housecall Pro by zip across Harris, Fort Bend and Montgomery counties, missed-call text-back inside a minute, a day 1/3/7 sequence on every replacement quote with the CenterPoint rebate and the dehumidification angle, and a review request 30 to 60 minutes after each repair. In Houston the season is long rather than spiky, so the receptionist pays for itself every month from May to October.
What HVAC calls look like in Houston
Houston HVAC is about humidity as much as heat. Systems in Sugar Land, Pearland, Katy and The Woodlands run from April to October, condensate drains clog, evaporator coils freeze, and homeowners call about “the house feels sticky” as often as “it is not cooling”. The season is six months long rather than ten weeks, which means the phone problem is constant rather than seasonal: Hatch’s 27% unanswered-call figure applies every day from May to October.
Then there are the storms. Hurricane Beryl knocked out power to more than two million CenterPoint customers in July 2024, and every Houston HVAC company got two waves of calls: systems that would not restart when power returned, and homeowners asking about surge protection and generators. Hurricane season runs June to November and every named storm in the Gulf repeats a smaller version. An AI receptionist that takes unlimited concurrent calls is the difference between booking those weeks and watching them go to voicemail.

| June–November (overlapping) | Hurricane season: post-outage restarts, surge damage, generator and surge-protector inquiries | Storm-week overflow handling; post-storm reactivation text to all customers |

Texts written for Houston HVAC customers
Replace the brackets. Every text comes from a named person and ends with a one-word question.
Missed call, within 60 seconds
“Hi, this is [Name] at [Company]. Sorry we missed you, every truck is out in this heat. Reply with your zip and what the system is doing (not cooling, humid, noise, water) and I will get you a time today.”
Humidity complaint booked by the AI
“You’re booked, [First name]: [Tech] will be at [address] in [Katy] between [1 and 3pm]. Sticky-house calls are usually a drain or coil issue, so he will check both. Dispatch fee $[89], waived with the repair. Reply CHANGE for another window.”
Replacement quote, day 3
“[First name], [Tech] here. The [Trane 17 SEER2] on your quote qualifies for CenterPoint’s $[amount] rebate this year, and the variable-speed blower is what fixes the humidity you mentioned. Want me to hold Thursday?”
Post-storm reactivation
“Hi [First name], [Name] at [Company]. Power is back across most of [Pearland]. If your system did not restart or is tripping, reply HELP and we will prioritise you. Stay safe.”

Rules that apply in Houston
TDLR rule 16 TAC §75.71 requires the TACLA licence number on advertising and on vehicles in 2-inch letters; put it in every text signature. Permits: the City of Houston, Harris County and the surrounding cities (Sugar Land, Pearland, The Woodlands, Katy) each permit water heaters, panel changes and roofing separately. Texting: under Texas SB 140 (effective 1 September 2025) texts to prospects are telephone solicitation, so sends stay between 9am and 9pm (noon to 9pm Sunday); follow-up to people who contacted you first is exempt from registration under the November 2025 settlement. Texas is one-party consent for call recording. CenterPoint’s residential HVAC rebates and the federal 25C credit change yearly; keep the current figures in the day-3 text. The City of Houston issues mechanical permits online to licensed contractors; Harris County and the surrounding cities (Sugar Land, Pearland, The Woodlands, Katy) permit separately.

Questions owners ask
How is Houston HVAC different from Dallas?
Longer season and more humidity. Houston runs May to October rather than June to September, and a large share of calls are about humidity, drains and frozen coils rather than pure no-cool.
Can the AI handle the week after a hurricane?
Yes. It takes unlimited concurrent calls, collects address and symptoms, texts safety and restart instructions and queues callbacks. You set the priority order.
Does it know Harris County versus Fort Bend trip fees?
Yes. Zones are by zip across Harris, Fort Bend, Montgomery, Brazoria and Galveston counties so it quotes the right fee and books the right truck.
What should the replacement follow-up mention in Houston?
The CenterPoint rebate, the humidity fix (variable-speed blower, proper sizing) and the install date. Humidity is the Houston closer.
Should I text customers after a storm?
Yes, once, to everyone: power status, a HELP keyword for systems that will not restart, and nothing salesy. It books the week and earns reviews.
Will callers hear a Houston number?
Yes. We keep your existing 713, 281, 832 and 346 number so nothing changes for customers or your truck wraps.
Does the AI know Houston neighbourhoods and zip codes?
Yes. Your service area across Harris, Fort Bend, Montgomery, Brazoria and Galveston counties is loaded so it books only where you work and quotes the right trip fee.
Is texting customers legal in Houston?
Yes. Texas SB 140 applies statewide: 9am to 9pm sends, noon to 9pm on Sunday, and follow-up to people who contacted you first is exempt from registration under the November 2025 settlement.
Do I need my licence number in texts?
In Texas, yes. TDLR rule 16 TAC §75.71 requires the TACLA licence number on advertising and on vehicles in 2-inch letters. A customer text is advertising, so the TACLA goes in the signature.
How long does setup take in Houston?
About two weeks, mostly waiting on number porting and A2P text registration. Local scripts and software connection take two or three days of that.
