Halden Heating & Air is the HVAC company Lockhart homeowners call when they’re done guessing at prices and done waiting through four-hour arrival windows. We show up with a written price before any work starts, a live arrival time you can track to your door, and a 365-Day Done Right Promise on every completed job. Lockhart’s mix of older pier-and-beam homes and newer slab builds means no two calls look the same, and we handle each one with that in mind. Call (361) 202-9170 any hour, day or night, and a real person answers.
Why Lockhart Homes Are Different
Lockhart’s historic downtown and the older neighborhoods around it have plenty of homes built before central air was standard. Many of those pier-and-beam houses never had ductwork installed, so heating and air work here often means retrofitting duct runs and high-efficiency systems into homes where every square foot of closet space already has a job. It’s a different kind of install than a new slab-on-grade build, and it takes a technician who has worked around old framing, low crawl spaces, and original floor plans. We approach those jobs with the same rule we bring everywhere: the written price comes first, before any equipment is ordered or any wall is opened.
The climate adds its own pressure. Lockhart summers are hot and humid, and the long cooling season means your AC’s condensate line works hard. When that drain clogs or the system isn’t dehumidifying properly, you feel it quickly, usually as a musty smell or water staining near the indoor unit. In the older, tree-lined streets near downtown, we also see original electrical circuits sized for window units. Those old panels often can’t carry the startup load of a modern central air system, which means a panel upgrade is part of the conversation before a new installation. That’s not a surprise we spring on you at the door. It’s part of the written estimate, talked through beforehand.
Styles & brands we work with







Our Main Lockhart Services
Most Lockhart calls to us come down to two things: an AC that stopped cooling in July, and a home that needs a full system swap. Furnace work picks up when the first cold snap hits, and all three services have their own Lockhart pages with full pricing and detail.
AC Repair in Lockhart
When your AC quits in a Lockhart summer, the humidity makes the house feel twice as warm within hours. Common repairs here include refrigerant recharge (topping off the coolant your system needs to produce cold air), condensate drain clearing, capacitor replacement, and thermostat wiring fixes on older homes. Most AC repairs run between $150 and $650 depending on the part, and every repair comes with a written guarantee and a free return visit if it fails. Full detail is on our AC Repair in Lockhart page.

AC Installation in Lockhart
Replacing a system in Lockhart often means more than swapping a unit. Older pier-and-beam homes may need ductwork added, and we account for panel upgrades, existing line set condition, and whether the home’s layout works better with a traditional split system or a different configuration. AC installation in this area typically runs $3,500 to $7,500, depending on equipment size and the work the house needs. You get a fixed written price before anything is ordered. See AC Installation in Lockhart for the full breakdown.

Furnace Repair in Lockhart
Lockhart winters are mild, but when a furnace’s heat exchanger or ignitor fails during a cold night, the house gets uncomfortable fast. Common calls include burners that won’t stay lit, blower motor failures, and cracked heat exchangers on older units. Furnace repair here typically runs $150 to $700 depending on the component, and every job includes a written guarantee. If it fails within the coverage window, we come back at no charge. Details are on our Furnace Repair in Lockhart page.

What pushes a Lockhart job toward the top of those ranges is usually the condition of the home itself. Older electrical panels, missing ductwork, and tight access in pier-and-beam crawl spaces add labor time, and labor is the honest variable. We factor it into the written price before we start, not at the door after the work is done. The number we hand you is the number you pay.
