AfterFast, Reliable Furnace Repair Across Alamo Heights
When your furnace quits during a cold snap in Alamo Heights, you need a repair crew that knows the difference between a 78209 permit and a San Antonio one. We do.

Our Furnace Repair team has been inside hundreds of pre-1960 custom homes here, from Olmos Park Terrace to the estate lots north of the Quarry. Call (747) 966-3037 and a live person answers, 24 hours a day.
What makes Alamo Heights different from every other pocket of San Antonio? The homes weren’t built around forced-air systems, which is why our AC Repair in Alamo Heights takes those original designs into account. They were built around high ceilings, plaster walls, and irregular floorplans, and the furnaces were added decades later, often badly. That changes what a repair actually involves here.
Why Meadowsweet Heating & Air Is Alamo Heights’s Preferred Furnace Repair Company
Luis Serrano leads our crews into Alamo Heights homes with a simple instruction: leave the house cleaner than you found it. That’s not a slogan. It’s the Cedarwell Care Promise, and it’s been the operating standard since 2004. Every visit includes a written price before work starts, shoe covers and drop cloths inside the house, and a photo of the cleanup before we walk out the door. No exceptions, no upsell.
Furnaces in this city fail differently than furnaces in newer suburbs. We know that because we see it week after week. The static pressure in a 1930s home on West El Prado Drive doesn’t behave like the static pressure in a 2010s build in Stone Oak. That’s not a marketing line. It’s what the manometer tells us.
We also carry parts for Trane, Lennox, Goodman, and Rheem systems, which covers a large share of the equipment we find in Alamo Heights. When a gas valve or ignitor fails, we’re usually not waiting on a supply house run. We’re finishing the job and explaining the invoice.
Furnace Tune Up in Alamo Heights
A Furnace Tune Up in Alamo Heights costs $80-$200 and is the single best way to avoid a midnight no-heat call. Given the humidity that moves through this part of South-Central Texas, burners and flame sensors collect corrosion residue faster than you’d see in El Paso or Lubbock. We clean them, test the gas pressure, inspect the heat exchanger for cracks, and measure static pressure across the duct system.
For homes built before 1960, a tune-up here isn’t just maintenance. It’s a diagnostic. Duct systems that were spliced through multiple renovations often hide airflow problems that shorten the life of a new blower motor. We catch those before they turn into a $700 repair.
What the Tune-Up Covers
We inspect the burner assembly, ignitor, flame sensor, gas valve, and blower motor. We test the heat exchanger for cracks with a scope, check venting for obstructions, and measure temperature rise across the system. You get a written report with photos and a clear list of what’s fine, what’s wearing, and what can wait.
When to Book It
Book before the first hard cold front of the season. For Alamo Heights, that’s usually late October to mid-November. Families with kids and pets tend to book weekdays during school hours, which is quieter and easier for everyone. We work around naptimes and pet routines. Just tell the dispatcher what you need.
Emergency Furnace Repair in Alamo Heights
Emergency Furnace Repair in Alamo Heights carries the same $150-$700 repair range as standard service, and we do not charge an overtime premium for nights or weekends. When a family loses heat on a 35-degree night with a toddler in the house, the last thing they need is a fee structure stacked against them. Call (747) 966-3037 and a person picks up. Not a voicemail tree.
Winter Storm Uri taught this city something painful: older Alamo Heights homes lost heat for days, and many furnaces that limped through the freeze developed cracked heat exchangers and failed ignitors in the following months. If your system hasn’t been looked at since that storm, an emergency call now is cheaper than a full replacement later.
What Counts as an Emergency
No heat on a cold night, a gas smell near the furnace, a blower that won’t spin, or a carbon monoxide alarm that keeps tripping. If you smell gas, shut off the furnace, leave the house if the odor is strong, and call us from outside. We’ll walk you through what to do before the truck arrives.
Same-Day Service in 78209
We dispatch from our San Antonio office, but crews serve Alamo Heights locally. Response time inside 78209 is usually two to four hours for emergency calls, depending on traffic through Broadway and Hildebrand. Morning calls tend to get there fastest.
Trusted Brands We Service in Alamo Heights
We service Trane, Lennox, Goodman, and Rheem furnaces across Alamo Heights, and we’re qualified across nine brands total. Most parts for these brands are on our trucks or in local supply. That means less waiting and fewer return trips. If your furnace is a Lennox from the 1990s or a Rheem installed after 2010, we know what fails on those units in this climate and what it costs to fix.
Common Furnace Repair Problems We See in Alamo Heights Homes
- High static pressure from spliced duct systems. Original 1920s-1950s ducts were never designed for modern forced-air systems. After decades of renovations and borrowed returns, static pressure climbs, the blower motor overamps, and the heat exchanger runs hotter than it should. That’s why a repair in a 1938 home on Hildebrand doesn’t always stay fixed. We measure the static pressure before we sell you a new blower.
- Heat exchanger cracks in freeze-cycled furnaces. The February 2021 freeze pushed old Alamo Heights furnaces harder than they were built to go. Systems that cycled continuously for days developed hairline cracks that only show up under a scope. We find these during tune-ups and repair calls. This is not a DIY fix. A cracked heat exchanger can leak carbon monoxide into the house.
- Undersized equipment struggling against high ceilings. Ten-to-twelve-foot ceilings and large estate additions mean a furnace sized for a standard San Antonio tract home runs near capacity for five months straight. Capacitors, contactors, and compressors wear out early. We see it constantly in the larger homes north of the Quarry.
- Corrosion from Gulf humidity on outdoor components. Coastal air and Gulf-driven humidity reach Alamo Heights, and outdoor units here corrode years faster than equipment in drier Texas metros. Coils pit, cabinets rust, and electrical connections oxidize. A furnace that shares airflow with a corroded outdoor unit picks up those problems indoors too.

FAQs About Furnace Repair in Alamo Heights
No. Alamo Heights is an independent municipality with its own building department. A furnace repair permit or gas-line reconnect must be pulled through Alamo Heights City Hall, not the City of San Antonio. A San Antonio permit is legally void inside 78209, and Alamo Heights inspectors actively red-tag work done on the wrong jurisdiction’s paperwork. We pull the correct permit every time. Call (747) 966-3037 and we’ll handle the paperwork.
Once a year, ideally in October before the first real cold front. The Gulf humidity that moves through this area accelerates corrosion on burners, flame sensors, and outdoor coils. An annual tune-up catches that buildup before it causes a shutdown. In homes built before 1960, we also re-check static pressure each year because duct systems here shift over time.
Short cycling in older Alamo Heights homes usually comes down to undersized equipment, high duct static pressure, or a failing capacitor. A house with 10-to-12-foot ceilings and a duct system spliced through three renovations moves air differently than a newer tract home. The furnace reaches the limit switch, shuts down, then fires again. We diagnose the cause with a capacitor test and a static pressure reading, not a guess.
Yes, more often here than anywhere else in the San Antonio area. Because Alamo Heights homes were mostly built between the 1920s and 1950s as custom residences with high ceilings and irregular floorplans, a repair that involves replacing equipment or re-sizing ducts should start with a Manual-J load calculation. It tells us the actual heating load of the house, not what a builder assumed decades ago. Skipping it is how furnaces end up oversized, short-cycling, and failing early.
We service furnaces from Trane, Lennox, Goodman, and Rheem, among nine brands total. We keep common parts for these brands on our trucks and in local supply, so repairs move fast. Whether your unit is a pre-2000 Lennox or a newer Rheem, our techs see that equipment in Alamo Heights homes every week.
