Halden Heating & Air is the HVAC company Terrell Hills homeowners call when they want a written price before any work starts, a live arrival time they can track to the door, and a repair backed by a written guarantee. Homes here are not like the rest of San Antonio. Thick masonry walls, original plaster, and ductwork retrofitted into 1920s-era floor plans change how heating and cooling systems should be sized, installed, and repaired. Whether it’s a failed AC compressor in August or a 1940s furnace that won’t fire in January, we handle it with upfront pricing and real answers. Call (903) 623-6784 any hour, day or night, and a live person picks up.
Why Terrell Hills Homes Are Different
Most of Terrell Hills was built between the 1920s and 1950s, and the housing stock reflects a time before central air existed. Large custom homes went up with plaster walls, steam or radiant heat, and floor registers fed by original gravity furnaces. Central air was added decades later, which means ductwork was squeezed into spaces never designed for it. Insulation levels vary wildly from room to room, and we regularly find patchwork ducts that leak conditioned air into attics and crawl spaces.
The terrain adds another layer. Terrell Hills sits above 700 feet with a dense live oak canopy, so summer highs run slightly cooler than central San Antonio, but the shade traps humidity. That combination, plus occasional winter freezes, means systems need real heating and cooling capacity, not a one-size-fits-none rule of thumb. Load calculations matter more here than in a 1990s suburb, because a wrong-sized unit will short-cycle, fight the humidity, and wear itself out years early.
We also see the leftovers of old retrofit jobs: asbestos-wrapped ductwork that hasn’t been touched since the Eisenhower administration, galvanized pipes corroded by decades of condensate, and wiring that predates modern code. None of that scares us. It just means we plan the job before we start it, and the price you approve is the price you pay.
Styles & brands we work with
Our Main Terrell Hills Services
The two calls we hear most from Terrell Hills homeowners are a dead AC in the middle of summer and an aging furnace that won’t start on the first cold night. Repair is usually the first step, but when a unit is past saving, a correctly sized installation is what actually fixes the problem for good.
AC Repair in Terrell Hills
A Terrell Hills AC repair is rarely a one-part fix, because most systems here were retrofitted into homes that weren’t built for them. The issue might be a failing capacitor, a refrigerant leak, or a blower motor working harder than it should against undersized ductwork. We diagnose the actual fault, quote a written price before touching a tool, and stock common parts for major brands on the truck. If the fix doesn’t hold, the written guarantee means we come back free. Full detail is here: AC Repair in Terrell Hills.
AC Installation in Terrell Hills
Installing a new AC in Terrell Hills means more than swapping boxes. The right unit depends on the home’s square footage, wall construction, window placement, shade from the live oaks, and the condition of existing ductwork. We run the numbers before recommending equipment, then hand you a fixed installation price with a set install date. No guessing, no surprise change orders. Everything you need to know before committing is on this page: AC Installation in Terrell Hills.
Furnace Repair in Terrell Hills
Winter freezes in Terrell Hills are short but sharp, and a furnace that won’t fire is an emergency. We work on modern gas furnaces, older standing-pilot units, and the occasional gravity system still holding on from the 1940s. A furnace repair here often means cleaning or replacing a thermocouple, unfreezing a condensate line, or addressing a cracked heat exchanger before it becomes a carbon monoxide risk. Written price first, guarantee included. Details live here: Furnace Repair in Terrell Hills.

AfterPricing for HVAC Company in Terrell Hills, TX
| Service | Typical range in Terrell Hills |
|---|---|
| AC repair | $150 – $650 |
| Furnace repair | $150 – $700 |
| AC installation | $3,500 – $7,500 |
| Tune-up | $80 – $200 |
What pushes a Terrell Hills job toward the top of those ranges is access. Older homes have tighter mechanical spaces, original ductwork that complicates a repair, and occasionally asbestos-wrapped lines that require careful handling. That’s why we don’t quote over the phone and then change the number at the door. You get a written price before any work begins, and that’s the price on the invoice.
