Austin's Home Performance Experts
Your Home Is a System. We Make It Work.
AC, ducts, insulation, air quality — tested and tuned together. Not guesswork. Not band-aids. Real diagnostics, real results.
Why Austin Star
Most HVAC Companies Guess. We Test.
Every system we touch gets measured — airflow, pressure, temperature drop, duct leakage. If they're not testing, they're guessing. That's not how we work.
Diagnostics First
Duct pressure tests, Manual J load calculations, air delivery readouts. The real problem gets found before anyone touches a wrench.
Whole-Home Approach
Your AC, ducts, and insulation are one system. Fixing one without checking the others wastes money. All of it gets tested.
Certified to a Higher Standard
NATE, NCI, Energy Star, EPA Universal, IICRC. Five industry certifications that fewer than 5% of Austin HVAC companies hold together.
Honest Assessments
Jon Esquival built this company on straight talk. He'll tell you if your system just needs a tune-up instead of a replacement. Every customer who's reviewed us mentions the same thing: no upselling.
What We Do
Services That Actually Fix the Problem
Cooling & Heating
AC Service & Maintenance
Regular maintenance saves 10% on cooling bills, according to the Department of Energy. In Austin's 7-month cooling season, that adds up fast. Tune-ups twice a year catch small problems before they turn into weekend emergencies.

Air Distribution
Duct Testing & Sealing
Your ducts run through walls, crawlspaces, and the attic. Leaky ducts waste energy and make rooms uncomfortable. But here's the catch: sealing ducts without testing first can choke airflow and kill your equipment. Testing comes before sealing. Always.

Building Envelope
Weatherization
Drafts around windows, doors, and hidden gaps add up. For older Austin homes, air leaks can account for 30% or more of your heating and cooling costs. Caulk, weather stripping, and insulation usually pay for themselves within a year.

Air Quality
Indoor Air Quality
The EPA reports that concentrations of some indoor pollutants can be 2 to 5 times higher than outdoor levels — and in some cases, up to 100 times higher. If you're dealing with allergies, dust, or that stale-air feeling? Your HVAC system is circulating the problem.

Connected Home
Smart Home & Diagnostics
Is one room always hot while another's freezing? Zoning controls and smart thermostats can fix that without replacing your whole system. Pair them with performance monitoring and your phone tells you when something's off before it becomes a repair bill.

Emergency
Water Damage Restoration
When flooding hits, materials start deteriorating fast. Leather shrinks, wood warps, carpet grows mold. IICRC certified in fire, flood, and odor restoration.

Fix It Right
We do the work, then test again to prove the improvement. You'll see the numbers change, not just take our word for it.
The Air You Breathe
Your Home's Air Might Be Making You Sick
Most people spend over 90% of their time indoors. The EPA has classified indoor air quality as one of the top five environmental health hazards. Your HVAC system cycles that air hundreds of times a day — every allergen, dust particle, and contaminant goes along for the ride.

What Our Customers Say
Jon is a friendly, helpful and very knowledgeable technician. He took time to explain the various components of my system and possible solutions. I trust that he has my best interest at heart and isn't just trying to upsell me.
They installed our A/C system 7 years ago and have done all our routine maintenance since. They are always on time and prepared. Everyone — from the owner to the office manager to the techs — has been very knowledgeable and friendly.
The services were top notch. I admired how honest he was in regards to what may or may not be covered in my home warranty and even spoke with them. Very pleased with the work performed.
Austin Star Services has done nothing but provide A+ customer service. Jon takes the time to explain everything in great detail. I am always in good hands with them.
