Furnace repair in Alamo Heights typically costs $150 – $700, and in most cases we can have a technician at your door the same day you call. Older homes here, particularly those from the 1920s through 1950s, fail in predictable ways, and we know exactly what to look for before a small problem turns into a cold house. Call (254) 271-2545 and a live person answers, day or night.
Alamo Heights is not a generic suburb. The housing stock has real quirks. Pier-and-beam foundations, original galvanized ductwork, two-wire thermostat systems, and infill construction from the 1980s and 2000s all sit side by side. A furnace repair that works fine in a newer development often goes wrong in a 1930s house if the tech never looks beyond the furnace itself. Our team serves Alamo Heights with that reality in mind.
Why Meadowsweet Heating and Air San Antonio Is Alamo Heights’s Preferred Furnace Repair Company
Our Furnace Repair team has worked on enough Alamo Heights homes to know the difference between a furnace problem and a duct problem. On streets like Argyle and Patterson, what sounds like a failing blower motor is often rusted-through ductwork in the crawlspace bleeding heat into the dirt. We test before we replace, which is why our written price before any work starts protects you from paying for a repair that would not have solved anything.
Every technician who steps onto your Alamo Heights property is background-checked and uniformed, and every one of them follows the C.A.R.E. values: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, Explain the price before the work. We lay down shoe covers and drop cloths on every visit, and we send you a photo of the clean-up before the crew leaves. No upcharge, no exception.
Luis Serrano leads our San Antonio-based operation, and he holds every job to the 365-Day Done Right Promise: if it’s not done right, we make it right. No runarounds, no fine print. That is the Cedarwell Care Promise carried into every Alamo Heights home we enter.
Styles & brands we work with
Boiler Repair in Alamo Heights
Boiler repair in Alamo Heights means working on homes built when radiators and hydronic heat were standard, and those systems demand a different kind of care. A boiler that knocks, leaks, or heats unevenly in a 1930s house on a pier-and-beam foundation often has sediment built up in the lowest cast-iron sections, or a circulator pump that has been wearing out quietly for years. We are familiar with these older hydronic systems, and we do not treat a boiler like a furnace with water in it.
Hydronic System Diagnosis
We check the expansion tank, the pressure relief valve, the circulator, and the return piping, not just the burner. In Alamo Heights homes where the original boiler was sized for a house that has since been added onto, water volume changes make correct diagnosis even more important. Boiler repair here runs $150 – $700 for most jobs.
Safe Operation Checks
Boilers in older Alamo Heights homes sometimes have original gas valves that no longer close tightly, or flue pipes that have shifted out of position. These are not cosmetic issues. We inspect every hydronic repair for safe combustion and proper venting before we pack up. If something is not right, we explain it clearly and give you a written price to fix it.
Gas Furnace Repair in Alamo Heights
Gas furnace repair in Alamo Heights often starts with the heat exchanger but ends somewhere else entirely. In these older homes, the furnace may be a late-1990s or early-2000s unit shoehorned into a closet or attic space that was never designed for it. The result is restricted airflow, high temperature rise, and a heat exchanger that cracks long before its expected service life. We look at the whole picture.
Heat Exchanger Inspection
A cracked heat exchanger is a carbon monoxide risk, and in a tightly sealed older Alamo Heights home, that risk does not dissipate quickly. If you notice a furnace smell that lingers, or if a carbon monoxide detector has gone off, shut the system down and call us. We inspect the heat exchanger on every gas furnace repair, and we tell you honestly whether repair or replacement is the right call.
Gas Valve and Ignitor Work
When the ignitor glows but the burners never light, or the furnace fires up and shuts off after a minute, the gas valve or flame sensor is usually at fault. In Alamo Heights homes where squirrels or rodents have gotten into crawlspace or attic ductwork, debris can also find its way into the burner assembly. We clean it properly, test it, and show you what we found before we leave.
Trusted Brands We Service in Alamo Heights
We service gas furnaces from Carrier, American Standard, and Daikin, among others, and we keep common parts stocked for the models we see most often in Alamo Heights homes. That local parts access means less waiting when your Daikin gas valve fails or a Carrier blower motor gives out on a cold night. We never push a brand replacement just because it is easier for us. If it can be repaired safely and cost-effectively, we repair it.

AfterCommon Furnace Repair Problems We See in Alamo Heights Homes
- Rusted galvanized ductwork in crawlspaces. Original 1920s – 1950s supply trunks under pier-and-beam homes rust through, and the furnace works harder while the house stays cold. We check static pressure before blaming the furnace.
- Two-wire thermostat wiring limiting modern furnaces. High-efficiency furnaces need more conductors to run variable-speed blowers. On old wiring, the system short-cycles and never reaches its efficiency ratings.
- Oversized furnaces in modest square footage. Many Alamo Heights homes have furnaces that are too big for the space, which causes short cycling, uneven heat, and premature heat exchanger failure.
- Original single-zone layouts leaving back bedrooms cold. A 1930s floor plan was never balanced for forced air. Without airflow correction, new equipment simply pushes the same uneven heat through the same undersized ducts.
Pricing for Furnace Repair in Alamo Heights, TX
Most furnace repairs in Alamo Heights fall between $150 and $700, depending on what has actually failed. An ignitor or flame sensor replacement sits at the lower end. A gas valve or blower motor runs higher. A cracked heat exchanger can push toward the top of the range or beyond, and in some older systems, replacement is the smarter financial decision. You will always know the written price before any work starts, so you never have to guess.

FAQs About Furnace Repair in Alamo Heights
The furnace is usually not the problem. In older Alamo Heights homes, the furnace is often oversized for the square footage, and the original ductwork was never balanced for a forced-air system. Heat short-cycles or gets dumped into the living room while the back bedrooms starve. We test static pressure and airflow before recommending any repair. Call (254) 271-2545 and we will trace the actual cause.
Sometimes, but not always. Variable-speed blowers need more thermostat wire than the original two-wire setup in many 1930s Alamo Heights homes. If the wiring cannot support it, the furnace will never run as designed. We check the wiring and the electrical panel before quoting variable-speed equipment, and we will tell you plainly if a small wiring upgrade is part of the job.
Usually, no. A musty smell at the start of the season often means dust or mildew on the evaporator coil or in the ductwork, and it burns off or blows out after a few cycles. But if the smell persists, or if you ever smell gas or something acrid, shut the system down and call us. We would rather check a false alarm than miss a cracked heat exchanger. Call (254) 271-2545 if anything smells off.
No. A failed capacitor is a small, inexpensive part, even in the older furnaces we see throughout Alamo Heights. We replace the capacitor, test the blower motor, and send you on your way. Only when the motor itself is failing, or the heat exchanger is compromised, does replacement become the honest recommendation. You will always see the written price before we do the work.
Short cycling, hot and cold rooms, high gas bills, and a furnace that runs constantly during a mild cold snap all point to sizing issues. In Alamo Heights homes from the 1920s – 1950s, the original furnace was often oversized, and a like-for-like swap repeats the mistake. We check square footage, duct sizing, and airflow before recommending any equipment. Call (254) 271-2545 for an evaluation.
