Carrier AC Repair: Blown Dual Capacitor in a Ridgetop Ranch

BeforeAfter

The problem: a Ridgetop homeowner called us at 6:40 on a July evening because the outdoor condenser was humming but the fan wasn’t spinning. That’s the classic signature of a failed dual capacitor, and in a 2024 Austin heat wave, waiting until morning isn’t an option. Our technician arrived, confirmed the diagnosis with a meter, and handed the written price before opening the panel. What we did: swapped the capacitor, tested the compressor and fan under load, and checked the refrigerant pressures while we were there. The result: cold air within the hour, and a repair note that explained exactly why it failed. That capacitor is covered for 365 days under the Done Right Promise.

Furnace Repair: Faulty Igniter in an Anderson Mill Split-Level

BeforeAfter

The problem: the furnace would click, the draft inducer would spin up, and then nothing. No flame, no heat, and a family in Anderson Mill waking up to a 58-degree house on a January morning. Hot surface igniters are a wear item, and after nine years, this one had hairline cracks you could see under a flashlight. What we did: replaced the igniter with the correct Lennox part, cleaned the flame sensor while the burner assembly was open, and ran a full cycle test three times. The result: reliable ignition on the first attempt, every attempt. The homeowner got the written guarantee before we packed up. Most igniter replacements in Austin run $150 to $280 parts and labor included, and it’s a repair we do several times each winter.

AC Installation: 17-Year-Old Goodman Swapped for a Trane in Circle C

BeforeAfter

The problem: a 2008 Goodman that had been limping along on refrigerant top-offs (topping off the cooling fluid your AC needs to run) finally developed a compressor leak, and the repair math didn’t make sense. The Circle C homeowner had us quote both the band-aid and the replacement. What we did: pulled the old condenser and air handler, replaced the lineset, and installed a matched Trane system correctly sized for the square footage and south-facing exposure. The result: a two-degree drop in runtime humidity, quieter operation, and a fixed install date that happened exactly when we said it would. No surprise line items, because the written price was handed over before the first tool came off the truck.

Furnace Repair: Blocked Pressure Switch on a Rheem in Wells Branch

The problem: a Rheem furnace was short-cycling and throwing a pressure switch code. A previous company told the homeowner they needed a new control board. When our technician pulled the inducer motor assembly, the real issue was a clogged condensate drain backing water into the switch line, a common issue in Austin’s humid winters when drains build up algae. What we did: cleared the drain, verified the switch was still functioning, and corrected the sloped venting that had been installed slightly off-pitch. The result: no more lockouts, no new control board, and a homeowner who saved about $400 on a misdiagnosis. The guarantee covers the work for a full year.

AC Repair: Refrigerant Leak Sealed in a Hyde Park Bungalow

The problem: the AC would cool for a week after a recharge, then blow warm again. Classic slow leak, and in a 1920s Hyde Park bungalow, the lineset runs through some tight, hard-to-reach chases. A refrigerant recharge without finding the leak is just renting cold air. What we did: ran an electronic leak detector over the evaporator coil, lineset, and service valves, found a pinhole at a braze joint, sealed it, pressure-tested with nitrogen, and then recharged to manufacturer spec. The result: a system that now holds its charge, verified with a post-repair leak check. The homeowner had been through three recharges with another company in two years. That’s the difference between topping off and actually fixing it.

AC Installation: Ducted System to Ductless Mini-Split in a Travis Heights Garage Conversion

The problem: a Travis Heights homeowner converted their detached garage into a home office, and the original plan tied it into the main house’s central system with a long, leaky duct run. The load math didn’t work, and the room never got below 79 degrees in the afternoon. What we did: quoted a single-zone ductless mini-split sized for the room, installed the wall unit and the outdoor condenser on a pad, and ran a clean lineset along the exterior with weatherproofing. The result: that office now holds 72 degrees on a 103-degree day, and the main house system no longer works overtime trying to cool a space it was never designed for. The Kingswell Way was in full effect on this one: price before work, window met, place left cleaner than we found it.
