Alamo Heights is not like the newer suburbs around San Antonio. The homes here were built in a different era, and they cool differently. That matters when a repair tech shows up.

The written price comes before any work starts. Every repair carries a written guarantee. That’s how we’ve built our reputation across Alamo Heights.

Why Halden Heating and Air San Antonio Is Alamo Heights’s Preferred AC Repair Company
Alamo Heights homeowners call us because we show up with a plan, not a sales pitch. Andre Fuller, who leads our team, built our process around a simple idea: a homeowner should see a locked written price before any tool comes out of the truck. That standard applies on every single job in Alamo Heights, from a quick capacitor swap near Broadway to a full refrigerant recharge on a 1950s ranch off Nacogdoches Road.
Our technicians don’t work on commission, so nobody is inventing upsells at your doorstep. We’re independently owned and operated, part of the Relay Home Co. network, and every job we complete falls under The Relay Visibility Guarantee. That means you get before-and-after photos, a written report of what was actually found, and a 365-Day Done Right Promise on the finished work. If a repair fails within the coverage window, the second visit is free. That promise is in writing, included automatically.
We know the streets of Alamo Heights because we work them constantly. Service calls here are different from calls in San Antonio’s newer suburbs. The homes are older, the ductwork is often original, and the demands of a Texas summer are brutal. We stock parts common to Alamo Heights systems, which means faster turnarounds when a condenser fan motor fails or a contactor burns out. Call (903) 623-6784 for a free estimate on any AC Repair need.
Styles & brands we work with
Emergency AC Repair in Alamo Heights
When the temperature inside your Alamo Heights home climbs past 85 degrees and the system won’t kick on, that’s not just uncomfortable. In a 1930s house with plaster walls and original windows, it can get dangerous for elderly residents, infants, or anyone with a respiratory condition. Emergency AC Repair in Alamo Heights typically runs $300 – $650 for after-hours service, and we answer the phone at 2 a.m. with a live person, not a voicemail tree. Our local crews stage from the San Antonio metro office and reach most Alamo Heights streets quickly.
After-Hours Response for Alamo Heights Homes
When your AC dies at midnight in June, you don’t want a callback tomorrow. You want a tech on the way. Our 24/7 dispatch team is staffed by real people who know Alamo Heights and can route a technician to your door with a live ETA. The after-hours rate is included in the Emergency AC Repair range above, and we give you a written price before any work starts, even at 2 a.m.
High-Humidity Failure on Historic Homes
Alamo Heights homes built before central air was standard often run hotter and muggier when a system fails, because the building envelope was never designed for mechanical cooling. If your upstairs is 90 degrees and the humidity is thick enough to curl wallpaper, call us. We carry the parts to get most systems running same-day, and we’ll check the ductwork while we’re there because in Alamo Heights, the ducts are often the real culprit hiding behind the failed part.
AC Not Blowing Cold Air in Alamo Heights
You set the thermostat to 72, the air is running, but the rooms aren’t cooling. AC Not Blowing Cold Air in Alamo Heights usually points to one of three things: a low refrigerant charge from a slow leak, a failing compressor, or a blower motor that’s spinning too slowly because the ducts are strangling it. The diagnostic to find out runs $150 – $250, and we’ll show you the readings and explain exactly what they mean before recommending any repair.
Refrigerant and Compressor Issues
Many Alamo Heights homes still have R-22 systems from the 1990s and early 2000s, or newer R-410A units that have developed pinhole leaks in the condenser coil. A refrigerant charge adjustment runs $200 – $500 depending on the amount and type. If the compressor itself is failing, we’ll give you the repair number and the replacement number side by side so you can decide with real information.
Ductwork and Static Pressure in Older Alamo Heights Homes
Here’s the part most companies skip. In Alamo Heights, a system can have a perfectly good compressor and still blow warm, weak air because the original ductwork is undersized or leaking. Our crew was called to a 1930s two-story on Estelle Drive for an AC not blowing cold air. After a five-minute capacitor test showed a weak dual-run capacitor on the 4-ton York condenser, we replaced it and then checked static pressure across the original duct runs, finding 0.9 inches of water column, well above the 0.5 the SEER2-rated evaporator coil needed. We corrected a leaking return plenum and rebalanced dampers, bringing static pressure down to 0.55 and dropping indoor humidity from 62% to 48%. That’s the difference between a parts swap and an actual fix.
Trusted Brands We Service in Alamo Heights
Our technicians are certified to service major brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Alamo Heights homes run everything from original 1980s Rheem units still chugging along to brand-new Daikin inverter systems with multi-zone controls. We keep a rolling stock of common repair parts for Goodman and York systems in our local trucks, because those two brands show up constantly in the 1980s and 1990s homes along Arcadia and Nogalitos. If we don’t have the part, we source it same-day from our San Antonio supply network and get your system back online fast.
Common AC Repair Problems We See in Alamo Heights Homes
- Undersized converted gravity furnace ducts. Many 1920s – 1930s Alamo Heights homes had gravity furnaces long before central air. When AC was added, the original ducts were reused, and they’re often too small for modern airflow needs. That causes high static pressure, premature blower motor failure, and rooms that never quite cool evenly.
- Frozen evaporator coils from low refrigerant. Long Alamo Heights summer run times expose pinhole leaks in older condenser coils. Low charge drops the coil temperature below freezing, ice forms, airflow stops, and the house gets muggy. We find this constantly in pier-and-beam homes where original line sets run through inaccessible crawl spaces.
- Patched window units creating infiltration problems. Historic Alamo Heights homes sometimes have old window-unit cutouts sealed with plywood and siding. These patches leak conditioned air and let outdoor humidity seep in. When homeowners finally switch to a modern heat pump or central system, we often have to upgrade the electrical panel too, because the original panel can’t carry the new load.
- Multi-zone imbalance in two-story homes. In a two-story Alamo Heights home with separate upstairs and downstairs systems, the upstairs unit does most of the work. Heat rises, attic ductwork bakes in the sun, and the upstairs system runs nearly constantly in July. If the upstairs system is slightly low on charge or the filter is dirty, it shows up as a 10-degree difference between floors.

AfterPricing for AC Repair in Alamo Heights, TX
You deserve real numbers before you decide anything. The table below shows what we charge for the most common Alamo Heights repairs. These are the prices we quote, in writing, before work starts.
| Repair Type | Typical Price Range (Alamo Heights) |
|---|---|
| AC Not Blowing Cold Air diagnostic | $150 – $250 |
| Capacitor replacement | $150 – $300 |
| Refrigerant charge adjustment | $200 – $500 |
| Emergency AC Repair (after-hours) | $300 – $650 |
What affects the final number? The refrigerant type matters. R-22 is no longer manufactured, so the remaining supply costs more than newer R-410A or R-32. The age of your system matters too. A 1995 Goodman condenser with a failing compressor is often a sign to look at replacement numbers, not just repair numbers. You’ll get a free estimate with honest options either way. Call (903) 623-6784 for an exact quote.

FAQs About AC Repair in Alamo Heights
Your system is probably oversized for the ductwork, not the house. In Alamo Heights, many 1930s homes still run on converted gravity furnace ducts that were designed for hot air rising, not cold air being pushed - a challenge our Alamo Heights Furnace Repair team understands well. Those ducts are often too small, so the system short-cycles or runs constantly without pulling enough moisture out of the air. The fix usually involves duct sealing, static pressure correction, and sometimes a dehumidifier paired with the existing system. Call (903) 623-6784 and we’ll measure it, not guess at it.
Yes, in most cases you can keep the original wall registers. The registers themselves rarely cause the problem. The issue is the ductwork behind them. A modern high-efficiency system needs proper airflow, and original 1920s ducts are often too small or leaky for the job. We can preserve the visible register faces while replacing or resealing the hidden duct runs. Many Alamo Heights homeowners care deeply about the architectural character of their homes, and we respect that. We’ll show you exactly what’s behind the wall before we recommend touching anything.
Look for large, ornate metal grates high on interior walls, often in hallways or near the center of the house. Gravity furnaces used big ducts and natural convection, so the grates are oversized. If your registers are small and placed oddly, or if the system struggles to cool certain rooms evenly, you probably have converted gravity furnace ducts. We can confirm it in about 15 minutes with a static pressure test. Call (903) 623-6784 for a diagnostic that gives you the real airflow numbers.
At 20 years old, a compressor failure or a leaking evaporator coil means you should look hard at replacement numbers before paying for an expensive repair. A new system for an Alamo Heights home typically runs $3,500 – $7,500 depending on size and efficiency. But the repair-versus-replace decision always comes down to the specific failure. A $200 capacitor on an otherwise healthy 20-year-old unit is a no-brainer repair. A $2,800 compressor is a different conversation. We’ll give you both numbers in writing, with no pressure either way.
Heat rises, and your upstairs system is fighting physics all summer long. In a two-story Alamo Heights home, the upstairs unit draws in hot attic air through leaky ducts, runs longer cycles, and works against the heat radiating down from the roof. If the upstairs system is even slightly low on refrigerant or has a dirty filter, the temperature split between floors can hit 10 degrees or more. We often find upstairs systems in Alamo Heights that were undersized from the start, installed during a renovation without a proper load calculation. Call (903) 623-6784 and we’ll measure the actual airflow and temperatures on both floors.
