Georgetown’s homes span a wide range, from historic houses near the downtown square to the sprawling subdivisions of Sun City and the new construction spreading north and east. What they all share is a dependence on air conditioning that runs hard through long Central Texas summers. When your system quits in July, the goal is simple: find a licensed company that answers the phone and gets you cool again fast.
This list of the best HVAC companies in Georgetown is built on public information, not paid placements. Every company below was reviewed for verified customer ratings, Texas HVAC licensing, years in business, and range of services. Nobody paid to be here, and we refresh this list each year as companies and their reviews change.
1. Quality Cooling, Heating & Plumbing
Address: 106 Halmar Cove, Georgetown, TX 78628
Website: qualitycool.com
Years in Business: Since 1984 (2020 in Georgetown)
License: TACLB021422E (plumbing M-9831)
Google Rating: 4.9 stars (1000+ reviews)
Services Offered:
- AC repair and installation
- Heating repair and installation
- Emergency HVAC
- Plumbing service
What Sets Them Apart:
Family-owned by Fred Bilbo and the Bilbo Brothers and serving Texas since 1984, Quality brought its small-town, do-it-right approach to Georgetown and quickly became the most-reviewed HVAC company in town. Reviewers describe crews who work carefully in 110-degree attics, walk homeowners through every step of an install, and never push unnecessary upgrades. With HVAC and plumbing under one roof, 24/7 emergency service, financing, and an A+ BBB rating, they cover just about everything.
Why They’re #1:
Four decades in business, nearly a thousand consistent local reviews, both HVAC and plumbing in-house, and around-the-clock service. For proven, full-service comfort in Georgetown, Quality leads.
2. Austex Air Conditioning & Heating
Address: 737 Co Rd 148, Georgetown, TX 78626
Website: austexair.com
Years in Business: Since 2007
License: Licensed and insured
Google Rating: 5.0 stars (432 reviews)
What Stands Out:
Owner David Smith has built Austex into a rare thing: a trusted company across more than 400 reviews. Homeowners describe him answering calls after hours without making them feel like a bother, taking the time to properly diagnose a system instead of jumping to a costly repair, and working around their schedules. Customers who’ve stuck with Austex for 20-plus years say it plainly: they’re reliable and honest. For a genuinely local, no-pressure HVAC company, Austex is hard to beat.
3. Altruistic AC, Heating & Plumbing
Address: 14408 Citron Cove, Pflugerville, TX 78660
Website: altruisticac.com
Years in Business: Since 2015
License: TACLB63701E
Google Rating: 4.9 stars (800+ reviews)
Services Offered:
- AC repair and emergency service
- AC installation and replacement
- Heating and furnace service
- Ductless mini-splits
- Indoor air quality
- Plumbing and water heaters, including tankless
Why They’re Listed:
Based to the south in Pflugerville, Altruistic covers Georgetown with fast response times. They often have a technician at the door within about an hour, even on nights and weekends. And across more than 800 reviews, homeowners describe their technicians as explaining the options without pressure and working to fit a budget rather than jumping to a costly replacement. Tech Ramon is named again and again for his patience, and the company texts a photo and short bio of your tech before arrival. With both HVAC and plumbing under one roof and certification to service older R-22 systems, they’re a well-rounded option for Georgetown homes.
4. Miller Climate Control
Address: 723 W University Ave, Georgetown, TX 78626
Website: millerclimatecontrol.com
Years in Business: Since 2017
License: Licensed and insured
Google Rating: 4.9 stars (457 reviews)
Local Reputation:
Owner Chris Miller has lived in Williamson County since 2001 and brings 25-plus years in the trade to every job he completes for clients. Homeowners describe his company as having fast response times even during heat waves and on weekends, providing honest diagnoses that fix the real problem the first time, and not pushing add-on services. One Sun City resident had Chris and his tech out within two hours after another company quoted a full day’s wait. Courteous, competent, and fairly priced is the through-line.
5. Arctic Air Company
Address: 2005 Mottey St, Georgetown, TX 78626
Website: arcticaircompany.com
Years in Business: Since 1987
License: TACLB97053E (NATE-certified)
Google Rating: 4.9 stars (291 reviews)
Why They’re Included:
The seasoned veteran on this list, Arctic Air has kept Georgetown cool since 1987, and some customers have used them for nearly 40 years. Family-owned with NATE-certified technicians, they’re praised for prompt scheduling (often next-day appointments), clear text reminders, and honest assessments, including catching a failing breaker that was contributing to an AC issue. For homeowners who value deep local roots and old-school reliability, Arctic Air is a trusted name.
How We Chose the Best HVAC Companies in Georgetown
We don’t accept payment for rankings. Every company here earned its spot on public information alone.
We looked at:
- Verified customer reviews, read for consistent patterns rather than raw star counts
- Current Texas HVAC licensing and insurance
- Years in business and a steady local track record
- How quickly they respond to Georgetown homeowners
- Range of services, from emergency repair to full installation
If a company couldn’t hold up across those factors, it didn’t make the list. We update these rankings each year to keep them accurate.
Best HVAC Companies in Georgetown FAQs
Most AC repairs in Georgetown run between $150 and $600, depending on the part and labor involved. A capacitor sits near the low end, while compressor or coil work costs more. Full system replacement typically ranges from $6,000 to $12,000. Always get a written estimate before approving work.
Yes. Several companies here, including Quality, Altruistic, and Arctic Air, offer emergency or 24/7 service, which matters when a summer breakdown turns dangerous fast. Expect after-hours rates to run higher than a standard visit, but for a dead system in July, it’s well worth the call.
Because Georgetown systems run so many months a year, once-a-year service is the minimum and twice is better: cooling in spring, heating in fall. Regular tune-ups catch small problems early, keep energy bills down, and extend the life of a system working overtime in this climate.
If your system is under about 10 years old and the fix is minor, repairing usually makes sense. Once a unit passes 12 to 15 years or faces a major cost like a broken compressor, replacement is often the smarter investment. A trustworthy local tech will walk you through both options honestly.
Yes. Every company on this list holds a Texas HVAC contractor license or operates as licensed and insured. Before any work begins, you can ask for the license number and proof of insurance, which any reputable company will share without hesitation. Licensing protects you and ensures the work meets state code.
