Our Services
Every repair uses parts matched to your system's specifications, not whatever is cheapest on the shelf — our technicians handle every air conditioning and heating need across Round Rock in Williamson County and the wider Austin metro — including Teravista, Forest Creek, Behrens Ranch.
A no-cool emergency does not get fixed properly with whatever generic part is cheapest — it needs the right component the first time. Our technicians carry manufacturer-grade stock for frozen coils, electrical faults, and dead compressors, available 24 hours a day, so the repair actually holds instead of failing again next week.
Diagnostic $89 — applied to repair
Guessing at a fix wastes your money and your AC. Our certified technicians run a full system diagnostic across capacitors, contactors, blower motors, and refrigerant charge to find the real cause, then repair it with parts matched to your brand and specifications — a fix meant to last years, not weeks.
Diagnostic $89 · Repairs from $149
A system that is undersized or mismatched to your ductwork will fail early no matter how good the brand is. We run a Manual J load calculation to size the replacement correctly, install high-efficiency equipment matched to your home, and keep manufacturer warranties intact — so what you get is durable cooling, not just a new box on the same shaky setup.
From $4,500 installed
Even good equipment wears out faster without upkeep. Our 21-point tune-up cleans coils, checks refrigerant charge, tightens electrical connections, and verifies airflow, catching the small part failures before they force an emergency replacement — the kind of maintenance that protects both your comfort and your manufacturer warranty.
From $79 per visit
Igniters, flame sensors, heat exchangers, and reversing valves all need to match your specific furnace or heat pump — an improvised part can create a safety issue, not just a comfort one. We repair gas furnaces, heat pumps, and electric heat systems with the correct components and finish every job with a full safety inspection.
Diagnostic $89 · Repairs from $149
Leaky ducts waste up to 30% of your cooling, and a quick tape job in a hot attic will not hold for long. We inspect the full run, seal and repair it with attic-rated materials, balance airflow room to room, and can add filtration, UV, or dehumidification equipment that keeps working long after the visit.
From $349
A mismatched thermostat can miscommunicate with your equipment and shorten its life. We select a smart or programmable model that is actually compatible with your system, wire and configure it to your Wi-Fi, and verify staging and fan control work correctly before we leave.
From $149 installed
Low refrigerant almost always means a leak, and just topping it off leaves the underlying problem untouched. We run electronic leak detection to find the actual source, repair it, recharge to the manufacturer spec, and replace failed compressors with correctly matched, EPA-certified handling so the system runs the way it was designed to.
Recharge from $249 · Compressor from $1,200
How It Works
Text us or give us a call and describe the problem — a real person answers any hour, day or night.
Our technicians stock manufacturer-grade components for the major brands, so the fix does not wait on a parts order.
We identify the actual failed component and give you a flat, upfront price before any work begins.
We install the correct part, test the system under real load, and stand behind the work so it does not fail again next month.
Why Choose Us
When the afternoon sun bakes the I-35 corridor and your air conditioning quits, Round Rock homeowners need help fast. Emergency AC Repair Austin dispatches licensed HVAC technicians across Round Rock — Behrens Ranch, Mayfield Ranch, Stone Oak and beyond — 24 hours a day, with flat upfront pricing on every call.
Much of Round Rock's housing stock went up during the Dell-driven growth of the 1990s and 2000s, so a lot of original 15-to-25-year-old condensers in Forest Creek and Teravista are now reaching the end of their service life right as summer peaks. The heat island along I-35 pushes those aging systems hard, and hard Williamson County water leaves scale on coils that quietly steals capacity. We size replacements with a proper Manual J load calculation for the two-story Behrens Ranch and Mayfield Ranch floor plans, so the upstairs actually keeps up.
Neighborhoods we cover in Round Rock, Williamson County, include Teravista, Forest Creek, Behrens Ranch, Mayfield Ranch, Stone Oak — and every street in between.

Reviews
“The last company had already swapped a cheap capacitor twice and it kept failing. These guys put in the correct manufacturer part and it has held fine ever since.”
“Honest diagnostic, no upsell. They explained exactly which part had failed and why, quoted the flat price, and it has run perfectly since.”
“Replaced our 18-year-old system with properly sized equipment instead of just matching the old tonnage. Clean install, and our energy bill dropped noticeably.”
“What stood out was they carried the actual part on the truck instead of ordering it and coming back a second day. Professional and fairly priced.”
“Great tune-up service. The tech caught a coil about to fail and replaced it with the right part before it turned into a midnight emergency.”
“Refrigerant leak found and repaired at the source instead of just topping it off like the last company. Cools better than it has in years.”
