Fast, Reliable AC Repair Across Austin

Why Halden Heating and Air Austin Is Austin’s Preferred AC Repair Company

We’re independently owned and operated under the Relay Home Co. network, and we’ve been holding to The Relay Visibility Guarantee since 2004. That means every job gets a written price before work starts, a written guarantee on every repair, and a free second visit if the repair fails. No fine print, no “that part wasn’t covered.” It’s the same standard you’d expect from a rideshare app: show me who’s coming, when they’ll arrive, and what it costs.

Austin homeowners call us because we speak the language of the city’s housing stock. We know a 1960s bungalow in Travis Heights has different duct problems than a 2005 tract home in Circle C. We know flex duct in a hot attic loses capacity fast. We know a 3-ton condenser can’t push air through a 2-ton-rated duct system without help. That’s the kind of local knowledge that turns a frustrating repair into a one-visit fix.

Our techs arrive in uniform, background-checked, and dispatched from our Austin office. You’ll see their live ETA on your phone, not a vague “sometime between noon and five.” And when the repair is done, you get before-and-after photos so you can see exactly what was fixed and why.

AC Unit Repair in Austin

AC Unit Repair in Austin means diagnosing and fixing whatever is keeping your system from cooling, from a failed compressor to a shorted control board. In a city where summer cooling demand runs April through October, a down unit isn’t an inconvenience. It’s a health risk for older residents and young kids. Most AC unit repairs in Austin run $150 to $650 depending on the part, and we carry common capacitors, contactors, and fan motors on the truck so we can usually finish the fix in one trip. You’ll get a written price before we start, and a written guarantee on the repair when we’re done.

What Actually Breaks

In Austin’s heat, capacitors fail first. They’re the little cylinders that give your compressor and fan motor the electrical kick they need to start. When one fails, the compressor hums but won’t spin, or the fan just sits there while the condenser coil bakes in the sun. We also see a lot of contactor failures from ant nests (Austin fire ants love the low-voltage wiring), and blower motors that have been running nonstop since April and finally give up in August.

Older Home Complications

On a 1978 ranch in East Austin’s Govalle neighborhood, our tech found a 3-ton Carrier condenser paired with a 2-ton-rated duct system. Static pressure was running at 0.9 IWC, double what it should be. The compressor was working fine, but the house couldn’t move enough air to ever feel cool. We corrected the blower speed, sealed the plenum, and replaced the failed dual capacitor. Now the whole house drops to 72°F without the old 8°F temperature split between rooms. That’s the difference between a parts-swapper and an AC repair tech who understands how an old Austin house actually behaves.

AC Capacitor Replacement in Austin

AC capacitor replacement in Austin is one of the most common repairs we do from May through September. The capacitor is the small metal can that stores and releases the burst of electricity your compressor and outdoor fan need to start up. Austin’s sustained 100°+ days cook these components, and we replace hundreds every summer. The part costs $150 to $400 installed, and the job usually takes under an hour. Every replacement carries our written guarantee, and if that capacitor fails again within the coverage window, we come back free.

Signs Your Capacitor Is Dying

The classic symptom is a humming sound from the outdoor unit but no fan spinning. Sometimes the fan turns slowly, or the compressor starts and stops every few minutes. Another tell: the AC works in the morning but gives up by late afternoon when the heat peaks. If you hear a clicking sound from the condensing unit followed by nothing, there’s a good chance the capacitor is done.

Why They Fail So Fast Here

Capacitors have a lifespan measured in hours of operation. In Austin, your condenser runs more hours per year than in almost any other Texas city because our shoulder seasons barely exist. A capacitor rated for 10,000 hours of use will burn through those hours in three to four Austin summers. That’s why we stock dual-run capacitors for every major brand on the truck, including Trane, Lennox, and Goodman.

Trusted Brands We Service in Austin

We’re certified to service every major residential brand, and we keep a local parts inventory in Austin so you’re not waiting on shipping when a Rheem fan motor or a Goodman control board fails. The brands we work on most often across Austin include Trane, Lennox, Goodman, and Rheem. Because Austin’s housing stock spans 1920s bungalows to 2020s high-efficiency builds, we see every generation of equipment. That cross-section of experience means we can diagnose a 20-year-old Rheem as confidently as a brand-new variable-speed Trane.

Common AC Repair Problems We See in Austin Homes

• Undersized flex duct in hot attics. Many 1970s-90s Austin homes were built with flex duct runs that were undersized from day one, and 20 years in a 140° attic hasn’t helped. Static pressure runs high, airflow runs low, and the AC runs constantly while rooms still feel warm. Duct testing and sealing is often a bigger improvement than a new compressor.
• Single-zone systems fighting an unbalanced floor plan. Older Austin houses, especially the center-hall and split-level designs common from the 1950s through the 1980s, were never zoned. One thermostat on a hallway wall means the west-facing bedrooms bake every afternoon while the east side freezes. Sometimes the answer is a simple balancing and airflow correction, not a new system.
• Old 100-amp electrical panels. Central and East Austin still have thousands of homes running original 100-amp panels. A new high-efficiency condenser plus heat pump strip heat for a winter freeze can pull more than that panel is rated for. We flag panel capacity before any install so you don’t trip the main breaker on the first cold night.
• Ant-damaged contactors. Fire ants love the low-voltage wiring inside condenser cabinets. They crawl in, get fried across the contactor terminals, and leave a conductive residue that shorts the system. It’s a weirdly common call in Austin, and one that gets misdiagnosed as a failed compressor more often than it should.
