Lost Creek is a pocket of West Austin where the houses sit big on wooded, sloping lots, and the air conditioning has to work harder than most systems in the county. We’re Halden Heating & Air, and we handle HVAC for the neighborhood: AC repair, AC installation, and furnace repair, every job priced in writing before work starts. If your system’s struggling in a 1970s custom home with vaulted ceilings and a condenser getting hammered by hail season, call us at (361) 202-9170. You’ll book online, get a live arrival time, and track your tech to the door.
Why Lost Creek Homes Are Different
Most of the HVAC calls we run in Lost Creek are in large custom homes built from the 1970s through the 1990s. These aren’t tract houses. They have slab foundations, multiple zones, and sprawling floor plans that put real strain on a central system, especially when the windows face west and the ceilings go two stories up. The local angle matters more than most people think: with limited commercial zoning and oversized lots, nearly every job we do here is high-end residential. Systems are frequently oversized to handle the heat gain from those expansive windows and vaulted ceilings, which means when something fails, it fails in a house that’s expensive to cool back down.
Then there’s the climate. Central Texas drives long, hot cooling seasons, and spring thunderstorms with hail can tear up an outdoor condenser in minutes. The oak canopy that makes Lost Creek feel private also shades the foundation enough to push indoor humidity up, so dehumidification control matters more than it does in a wide-open subdivision in Kyle. We see a lot of frozen evaporator coils in walk-in attic closets here, where cramped access and poor ventilation mean a coil ices over before anyone notices the temperature creeping. Fixing that right means more than thawing the lines; it usually means adding a secondary float alarm and an auxiliary drain pan switch so it doesn’t happen again.
Styles & brands we work with







Our Main Lost Creek Services
The two services Lost Creek homeowners call about most are AC repair in the thick of summer and full AC installation when an aging system finally gives out, with furnace repair picking up fast once overnight lows drop into the 30s. Each has its own dedicated Lost Creek page below.
AC Repair in Lost Creek
When a system in Lost Creek quits in the middle of July, it’s usually one of three things: a blown capacitor, a refrigerant leak, or a condenser that’s been beat up by hail off the back patio. We diagnose it the same day, show you a written price before the repair starts, and include a written guarantee on the fix. If the repair fails within the coverage window, the second visit is free, automatically. For a full breakdown of what repair costs here and how fast we can get to your street, see AC Repair in Lost Creek.

AC Installation in Lost Creek
Replacing an AC system in Lost Creek isn’t a drop-in swap. The older custom homes here often have partially finished attics that complicate duct retrofits, and sizing a new unit wrong, especially on a house with vaulted ceilings and west-facing glass, means a system that never dehumidifies properly. We survey the house, run a load calculation, and hand you a fixed written price before anything is ordered. You’ll get a set install date and we’ll handle any rebate paperwork. See AC Installation in Lost Creek for pricing and what the process looks like.

Furnace Repair in Lost Creek
Furnace calls in Lost Creek spike after the first real cold snap, and the issue is frequently a dirty flame sensor or a failing igniter in a closet-mounted unit that hasn’t been touched since spring. We repair furnaces across the area with the same upfront written pricing and written guarantee we put on every AC job. No overtime surcharges, no second-guessing the price at the door.

FAQs About HVAC Company in Lost Creek
Same day in most cases, and we give you a live arrival time when you book so you’re not waiting on a four-hour window. For anything after hours, a real person answers the phone 24/7 and we’ll dispatch from the Dallas-Fort Worth office to a local Lost Creek crew.
Some streets in Lost Creek fall under deed restrictions, but we haven’t encountered an HOA that restricts AC units outright. What we do see regularly is a need to screen condensers from view, and we can recommend placement that works with your lot’s sight lines. If you have a specific HOA question, we’ll note it on the quote.
No. The drive and the access are part of the job, not an add-on. The only thing that changes your price is what we actually find when we look at the system, and you’ll see that in writing before anything starts. Call (361) 202-9170 for a free estimate and we’ll come out and take a look.
