AC repair in Georgetown, TX covers an unusually wide range of houses: Victorian and early 20th-century homes a few blocks from the Williamson County Courthouse, thousands of single-story homes in Sun City Texas, and brand-new subdivisions going up on what was ranchland a few years ago. Each brings its own kind of service call. This page walks through them, along with the city-owned electric utility and what it offers, and how the free phone line works.
Austin AC Service is not an HVAC company. It is a free line: call (737) 378-9016, an automated assistant takes your name, number, ZIP and a short description of the problem, then the call rings through to a locally owned HVAC business that covers Georgetown. That company diagnoses the system and quotes the repair, and you pay it, not the line.
Georgetown AC repair calls come from three very different kinds of homes
Sun City Texas opened in 1996 with 522 homes and 940 residents. By its 25th anniversary in 2021 it had grown to nearly 8,500 homes and about 15,700 residents, all in a community for people 55 and older. Many of those houses are on their second air conditioner already, and some of the earliest are well into the age where a third becomes a real conversation. For a household of retirees, a dead system in August is a health question first and a budget question second.
At the other end of town, the city has added homes faster than almost anywhere in the country. Close to the square, Georgetown's older houses were built long before central air, and every duct run in them was added later, through tight crawlspaces, closets and attics that were never planned for it. A technician who works in all three settings sees a different set of problems on each street.
If the AC fails in a home with older adults
The CDC lists people 65 and older among those at higher risk from extreme heat: the body adjusts less well to sudden temperature changes, and common medications and chronic conditions can make it worse. It also warns that an electric fan does not prevent heat illness once indoor temperatures climb into the upper 90s. Austin's official station logged 80 days at 100 degrees or above in 2023, so this is not a rare scenario.
- Move to a cooler place first. A neighbor, a family member's house, or an air-conditioned public building. Do not wait in a hot house for the repair.
- Watch for warning signs. Confusion, dizziness, fainting, a racing pulse or hot, dry skin mean call 911 now.
- Keep water close and curtains shut on the sunny side of the house until cooling is back.
- When you call the line, say an older adult lives in the home. The company you are put through to can then decide how to prioritize the visit; the line itself cannot promise a time.
- Calling for a parent from out of town? That works. Give their Georgetown address and the best number to reach someone at the house.
Georgetown's own electric utility, and what it offers for your AC
Georgetown runs its own municipally owned electric utility. Most homes inside the city buy power from it, at rates set by the City Council, while parts of the surrounding territory are open to Oncor and Pedernales Electric Cooperative. Austin Energy programs do not apply here.
- Free HVAC tune-up, once a yearThe city's electric utility offers one free residential tune-up a year to Georgetown Electric residential customers who own the home. The system has to be a working central AC, heat pump or furnace; window units do not qualify. The visit covers safety checks, cooling and heating maintenance, an airflow and duct inspection and performance testing.
- Free home energy audit, every two yearsHomeowners who have lived in the house at least a year, in a home at least five years old, can request an audit that looks at bills, the HVAC system, lighting and appliances and ends with a written report.
- Gas comes from Atmos EnergyIf you heat with a gas furnace, Atmos Energy is the gas utility in Georgetown. A rotten-egg smell means get everyone outdoors first, then phone Atmos or 911 from the yard or street. Never hunt for the leak.
- Check before you replaceUtility programs change. Before you sign for a new system, ask the city utility, or Oncor or PEC if one of them is on your bill, what is currently offered and what paperwork it needs.
The free tune-up is maintenance on a system that runs. If the house is not cooling, a tune-up appointment is the wrong tool: call for a repair instead, and use the city program next spring.
Historic homes near the square
Georgetown's downtown, built around the 1911 Williamson County Courthouse, was named one of the American Planning Association's Great Places in America in 2018, and the city protects it with Downtown and Old Town historic overlay districts. The Old Town district covers the largely residential blocks between downtown and Southwestern University and south toward 17th, 18th and 19th Streets.
For air conditioning, older houses raise three practical questions. First, where can equipment go: exterior changes in the overlay districts are reviewed against the city's design guidelines through a Certificate of Appropriateness, so moving a condenser to a street-facing spot may need approval. Second, ductwork: retrofitted ducts in old homes are often undersized or squeezed into spaces that leak heat, and a good technician should test airflow before blaming the equipment. Third, sizing: a house with plaster walls, high ceilings and big windows does not behave like a new build, and a replacement should be sized with a proper load calculation, not by copying the old unit's tonnage. Ductless mini-splits are one option some owners consider for rooms the ducts never reached.
Services Georgetown callers need most

HVAC Maintenance and Tune-Ups
A spring cooling check before the heat and a fall heating check before the first freeze, and what a real tune-up includes.
How fast Georgetown has grown
Growth matters for repairs because it shapes the age of the equipment. A neighborhood built in one wave tends to wear out in one wave too.
| Year | What happened |
|---|---|
| 1996 | Sun City Texas opens with 522 homes and 940 residents. |
| 2010 | The census counts about 47,400 people in Georgetown. |
| 2020 | The census counts 67,176, up roughly 42 percent in ten years. |
| 2021 | Sun City reaches about 8,488 homes and 15,700 residents. |
| 2023 | The Census Bureau names Georgetown the fastest-growing U.S. city with more than 50,000 people. |
| July 2024 | The Census Bureau estimates 101,344 residents. |
In practice, homes from Sun City's first decade and the subdivisions of the late 1990s and 2000s are where replacement questions come up most. Homes from the last few years are more likely to have warranty questions: keep the equipment registration and the installer's paperwork, because manufacturer parts coverage often depends on them.
Why Georgetown homeowners call the line
- A parent or neighbor needs help fast. Adult children often call on behalf of a parent in Sun City. The line answers any hour, takes the address and puts the caller through to a licensed company that serves Georgetown.
- The house is old and the problem is unusual. Retrofitted ducts, tight equipment closets and historic-district rules call for a company used to older homes. Describe the house when you call so the company knows what it is walking into.
- New to town, no regular company yet. With the population up by tens of thousands since 2020, many residents have never needed an HVAC company here. Before anyone works on your system you can type the company's license number into the state's free TDLR search; all the companies reachable through the line are licensed ACR contractors.
- The call costs nothing. The line never charges the caller. You deal directly with the company you are put through to, and it gives you its price before any work starts.
Freezes in Georgetown
Winter matters here too. During Winter Storm Uri in February 2021, ERCOT ordered utilities to shed load, and Georgetown's utility lost remote communication with many of its electric assets, so staff drove to substations to switch circuits by hand. Some Georgetown neighborhoods went 12 hours or more without power, and the city later issued about $45 million in bonds to cover the storm's energy costs. A heat pump that sat dead through a freeze, or a gas furnace that has not been checked in years, deserves a look in the fall. The heating repair page covers what that check should include.

Permits for a new system in Georgetown
The City of Georgetown requires a permit to install, alter, repair or replace mechanical, electrical, gas or plumbing systems, which includes a full AC or furnace change-out. Inside city limits the city's inspection division is the authority, and inspections are requested online. The licensed installer normally pulls the permit and books the inspection; ask whether that is in the quote. If you are in an overlay district and the outdoor unit is moving, the historic review comes first.
- Call any hourAn automated assistant answers (737) 378-9016 and asks whether it is about cooling or heating.
- Describe the problemGive your name, a callback number, your city or ZIP and what the system is doing.
- Get put throughThe call goes to an independent, locally owned HVAC company, which hears a short summary before it picks up.
- Deal with them directlyThat company diagnoses, quotes, does the work and is paid by you. If it cannot answer, it gets your details to call back.
How this line works: Austin AC Service is a free phone line, not an HVAC company. It does not repair, install, quote or schedule work and holds no license. Calls are transferred to independent, locally owned HVAC companies that hold Texas air conditioning and refrigeration contractor licenses. Those companies may pay Austin AC Service a referral fee. You never pay the line. How it works.
Check any license yourself. Texas air conditioning and refrigeration contractors are licensed by the Texas Department of Licensing and Regulation. Ask for the license number and look it up at tdlr.texas.gov (opens in a new tab).
