People searching for AC repair in Tomball, TX, live in a mix of places: an established neighborhood near the old downtown, a new subdivision off State Highway 249, or a house on several acres down a county road. Each one raises different questions about permits, fuel and the trip out. The notes below cover what to sort out first and what a call to the line involves.
Houston Air & Heating is a free line, not an HVAC contractor. At (832) 662-4107, an automated assistant notes the problem, heat or cooling, and where the property sits, then patches you through to a heating and cooling business owned locally and working around Tomball. That business sees the equipment, names a price, does the job and bills you itself.
Tomball: a small city with a big rural edge
Tomball is an incorporated city in northwest Harris County with its own city government, set along State Highway 249, which locals call Tomball Parkway. The city itself is compact, but the Tomball name on mailing addresses reaches well beyond its limits into wooded subdivisions and acreage in unincorporated parts of the county.
That spread is the most practical thing to know about cooling and heating here. A home in town and a home on acreage a few miles out may share a ZIP code and still differ on who issues permits, whether natural gas reaches the house, and how far a technician has to drive.
The town began as a rail stop called Peck and took the name Tomball in 1907, honoring Thomas Ball, the Houston lawyer and congressman credited with bringing the railroad through. Oil was struck nearby in 1933, the same year the city incorporated.
A growing town with its own gas system
The 2020 Census counted 12,341 people in the City of Tomball, up from 10,753 in 2010. The Census Bureau's estimate for July 2023 was 14,201, so growth has continued since the count, and the unincorporated land around it with Tomball addresses is growing too. New houses mean new systems still under warranty sitting next to older homes on their second or third air conditioner.
- Natural gas inside city limitsThe City of Tomball owns and runs the gas system within the city and bills it on the city utility account, so a gas leak or meter question in town goes to the city, not a private gas company.
- ElectricityThe city does not sell power. It points residents to the state's Power to Choose site to pick a retail electric provider, and CenterPoint Energy lists Tomball in its electric delivery area, so CenterPoint owns the poles and wires and handles outages.
- CountyTomball is in northwest Harris County. Acreage outside the city falls under Harris County, with no city building department.
- Permits in townThe city has its own mechanical permit application for heating, ventilation and air conditioning work.
Inside city limits or outside: what changes
Not sure which side you are on? Your property tax statement lists every taxing unit for your home, and the City of Tomball appears there only if you are inside its limits.
Inside the City of Tomball
The city has its own building rules, and its mechanical permit application covers heating and air conditioning work. The city's fee schedule charges double the permit fees for work done before a required permit is issued, and the application says a permit becomes void if work has not started within six months. Have the HVAC company apply for it and show the permit as a line on the quote.
Unincorporated, Tomball address
There is no city building department for your home. The state license requirement still applies, and a subdivision with deed restrictions may want to approve new outdoor equipment.
Gas, propane or all electric
How your Tomball home heats decides who you call when it does not. Check your bills and the equipment label so you can tell the assistant and the company right away.
| If your heat runs on | Call an HVAC company for | Call the fuel supplier for |
|---|---|---|
| Natural gas | A furnace that will not light, short cycles or blows cold | Gas leaks and meter problems. Inside city limits that is the City of Tomball's gas utility; outside, use the emergency number on your gas bill |
| Propane | The furnace and its controls | Tank level, deliveries, and leaks at the tank or lines |
| Electric heat pump | Cool air in heat mode, ice that does not clear, a noisy outdoor unit | Your electric company only if the whole house is without power |
Safety first: if you smell gas or propane, get everyone outside, then call the supplier's emergency line or 911 from outdoors. The city's own gas guidance makes the same point: do not use a phone or light anything inside, because a spark can ignite the gas. If a carbon monoxide alarm sounds, leave the house and call 911. Never try to relight or adjust a burner yourself.
New equipment, old ducts
A common Tomball story: an older house gets a new outdoor unit and the back bedroom is still warm. Ducts that were run decades ago may leak at the joints, sag in the attic or feed air back through a return that is too small for today's equipment. A correctly sized system cannot fix air that never reaches the room. When you collect replacement quotes, ask each company:
- Did you measure the house? A load calculation looks at the actual home, not the old unit's size.
- What about the ducts and the return? Ask whether they were inspected and what the quote does about them.
- Are the indoor and outdoor parts matched? A new outdoor unit paired with an old indoor coil can cause repeat problems.
- Is there a trip charge? For a home on acreage outside town, ask before the visit.
- May I have your ACR license number? Run it through the TDLR search before anyone starts.
Outdoor units on big lots
A condenser on an acre or more lives a rougher life than one tucked between two suburban fences. Riding mowers and string trimmers throw grass and gravel at the coil. Vines and brush creep in from the tree line within a season. Long runs of refrigerant line and wiring from a detached shop or a house set far back can be nicked by equipment or chewed by animals. None of that is a reason to open the unit yourself, but it is worth a look when you mow:
- Keep a clear ring of a couple of feet around the outdoor unit, and point mower discharge away from it.
- Watch the insulation on the larger refrigerant line. If it is torn or missing, mention it to the company you reach.
- Note anything odd such as a burnt smell, a bent fan guard or a pad that has sunk and tilted, and describe it on the call.
Before you call: quick checks
Make sure the thermostat is on the right mode with a sensible setting, swap a filter that is gray with dust, and give a tripped breaker a single reset. On a wooded or rural lot, look for leaves, grass clippings or vines packed against the outdoor unit, and clear them by hand with the system off. If the breaker trips again or the unit hums without starting, stop and call. Long outages after storms such as Hurricane Beryl in July 2024 are also a good reason to learn where your breaker panel is before you need it.

About this line: Houston Air & Heating is a free phone line, not an HVAC contractor. It answers your call and connects you with an independent local heating and air conditioning company, which inspects, quotes and does the work, and which you pay directly. Companies may pay a referral fee. You never pay the line. Read how the line works.
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.
