AfterHVAC Company in West Lake Hills, TX
Dalton Heating & Air is the HVAC company West Lake Hills homeowners call when a system fails on the wrong day. West Lake Hills sits in Texas Hill Country, where summer temperatures routinely climb past 100°F and winter cold snaps punish undersized heat pumps. The homes here range from 1960s ranch houses tucked into limestone hillsides to newer custom builds with zoned systems and tight HOA rules. That mix means every job starts with a real look at the house, not a scripted upsell. Call (361) 306-9515 and you’ll get a written price before any work starts, plus a full-year written guarantee on every repair.
Why West Lake Hills Homes Are Different
West Lake Hills is not a flat, easy subdivision. It’s carved into the hills west of Austin, with oak-covered lots, steep driveways, and a patchwork of homes built across five different decades. Many of the older houses along Redbud Trail and Westlake Drive still run original ductwork sized for equipment that’s long gone. We routinely find return-air paths that were fine for a 1990s air conditioner but choke a modern high-efficiency heat pump. That mismatch shows up as uneven room temperatures and higher bills, and it’s one of the most common calls we run in the 78746 ZIP.
The terrain also changes the labor. Condenser pads sit on slopes, which means drainage and airflow need more attention than they do on a flat lot in a neighboring city. Some properties fall under West Lake Hills’ tree preservation rules, so relocating an outdoor unit can require routing lines around protected oaks. And because many homes here have upgraded exteriors – stone, stucco, cedar – line sets often run through tight chases that punish sloppy work. None of this is exotic. It’s just the reality of doing HVAC work in West Lake Hills properly, and we plan for it on every estimate.
Our Main West Lake Hills Services
These are the two jobs West Lake Hills homeowners call Dalton about most often: a cooling system that quit during a heat wave, and a planned swap to a heat pump that actually fits the house. Here’s what each involves locally.
AC Repair in West Lake Hills
When an air conditioner stops cooling in West Lake Hills, the usual suspects are a failed capacitor, a clogged condensate drain, or a low refrigerant charge. All three are common in this climate because the equipment runs hard from May through September. Our technicians test the system under load, not just at the thermostat, and they write up the exact repair with a fixed price before turning a wrench. Most AC repairs in West Lake Hills run $150 – $650 depending on the failed part. Full details, including same-day scheduling and the written one-year guarantee, are on the AC Repair in West Lake Hills page.
Heat Pump Installation in West Lake Hills
A heat pump is often the right replacement for a West Lake Hills home because it handles both cooling and heating with one outdoor unit. But sizing it correctly matters more here than in flat, treeless neighborhoods: hillside lots create shade on one side of the house and full sun on the other, which throws off a rule-of-thumb calculation. We run a proper load calculation, match the indoor coil to the outdoor unit, and only then put a written number in front of you. Heat pump installations in West Lake Hills typically run $3,500 – $7,500. See the Heat Pump Installation in West Lake Hills page for what’s included.
Furnace Repair in West Lake Hills
Furnaces run less often here than they do farther north, but when a cold front hits, a dead furnace makes a West Lake Hills house uncomfortable fast. Common failures we see are ignitors, flame sensors, and pressure switches – parts that wear from age more than from use. Every furnace repair includes a written diagnosis, a fixed price before work begins, and a written one-year guarantee on the repair itself. Most furnace repairs land between $150 and $700 depending on the part. See the Furnace Repair in West Lake Hills page for more on what we check.

Brands We Service in West Lake Hills
Our trucks carry parts for Trane, Lennox, Goodman, and Rheem systems – the brands most common in West Lake Hills homes.
