The line takes heating and air conditioning calls from the City of Houston and the suburbs around it. Each town below has its own page about what is different there: how old the houses are, which utility owns the wires, how flooding and storms have hit, and who handles permits.
How coverage works: an automated assistant answers (832) 662-4107 at any hour, asks where you are and what the heating or cooling is doing, and passes the call to a separately owned local HVAC business serving the Houston area. The line has no office in any of these towns and does not send anyone itself. The company you reach decides whether it can take the job, prices it and does the work.

Cities, townships and unincorporated areas
Greater Houston mixes three kinds of places, and the difference matters when equipment is replaced. Incorporated cities such as Houston, Sugar Land, Pearland, Katy and League City run their own permit offices. Kingwood is part of the City of Houston, so Houston's rules apply there. The Woodlands is governed by a township with its own residential design review. Cypress, Spring and Fresno have no city government at all.
You do not need to sort this out before you call. It helps to know it when you compare quotes for a replacement: ask each company whether a permit or design approval applies at your address, who obtains it, and whether the inspection is included.
Who owns the wires where you live
Power outages are common in Houston hurricane season, and a dead air conditioner during an outage is a utility problem, not an HVAC one. Across most of the area, CenterPoint Energy delivers electricity and you buy it from the retail provider you choose. Parts of Montgomery County, including Conroe and some neighborhoods of The Woodlands (which is split between two utilities), are on Entergy Texas lines, and much of Galveston County, including Friendswood and League City, is on TNMP lines. The company that delivers your power is printed on your bill, and that is who to call about an outage.

Verify the license before work begins. Texas requires anyone contracting to do air conditioning, refrigeration or heating work to hold an Air Conditioning and Refrigeration (ACR) Contractor license from the Texas Department of Licensing and Regulation (TDLR). Ask the company for its ACR license number, then confirm it on the TDLR license search (opens in a new tab). The line does not check this for you.
