Keeping Alamo Heights
Warm — Without the Drama.
Alamo Heights isn’t Bulverde. While newer suburbs north of Loop 1604 deal with construction dust on brand-new heat pumps, homeowners in 78209 face a different challenge entirely: gas furnaces and central systems that were installed when the neighborhood was young — many dating back 20 to 40 years — that now struggle to fire up reliably when the first “blue norther” rolls in off the plains each December.
Because San Antonio’s winters are mild, most Alamo Heights furnaces sit completely dormant for 9 to 10 months. That long dormancy is hard on ignitors, heat exchangers, limit switches, and draft motors. The result: the one week a year your heat actually matters, it fails. Our team runs through a specific “first-start” diagnostic designed for exactly this situation — not a generic checklist, but a targeted inspection of the components most likely to fail in a system that’s been sitting since February.
We also specialize in the original ductwork configurations found in Alamo Heights craftsman bungalows, mid-century brick ranches, and Spanish colonial-style homes along Broadway and Austin Highway. These aren’t cookie-cutter layouts. They require someone who knows what a 1970s attic duct system looks like — and how to restore it to full efficiency without gutting your ceilings.
The Alamo Heights Air Quality Problem Most HVAC Companies Miss
🌲 Mountain Cedar Invasion
Alamo Heights sits in the epicenter of Central Texas’ Mountain Cedar (Juniperus ashei) zone. December through February, cedar pollen counts reach 15,000+ grains/m³—causing cedar fever that mimics flu symptoms. Unlike other regions, cedar pollen penetrates even closed homes through aging weatherstripping in 1920s-1940s construction. Standard 1-inch filters capture only 30% of cedar pollen particles.
🏛️ Historic Home Challenges
Spanish Colonial and Tudor homes (1920s-1940s) dominate Cambridge, Terrell Hills, and Olmos Park—thick stucco walls create humidity pockets, original ductwork has 20-30% leak rates, and undersized return air vents concentrate allergens on upper floors. Modern HVAC systems struggle to circulate air through period construction not designed for central cooling.
💧 Year-Round Humidity Battle
San Antonio averages 73% humidity year-round. Alamo Heights’ microclimate near Olmos Basin and Brackenridge Park adds 5-10% more moisture. Historic homes’ original HVAC drain pans lack proper drainage—mold grows invisibly in attics and ductwork. Thick Spanish Colonial walls prevent proper moisture escape, creating persistent musty odors despite cleaning.
Heater Installation — Alamo Heights TX
If your current system is more than 15–18 years old, replacement may be more cost-effective than continued repair. We install both gas furnaces and modern heat pump systems and provide an honest comparison of both options for your home’s age, duct configuration, and energy goals. Installation quotes include Bexar County permit handling at no extra charge.
Heater Repair — Alamo Heights TX
When your furnace stops working or struggles to hold temperature on a cold January night, our technicians diagnose the issue and complete the repair using quality parts — same day when we’re not fully booked. Flat-rate pricing quoted before any work begins. Most repairs in Alamo Heights homes fall into our Level 1–4 range ($105–$638).
Heater Maintenance — Alamo Heights TX
Because Alamo Heights furnaces sit idle for so long, we recommend scheduling your tune-up in October — before the first cold front arrives and our calendar fills up. A $58 seasonal tune-up includes a full ignitor test, heat exchanger inspection, flue pipe cleaning, burner assembly inspection, and thermostat calibration. Your system will be ready when temperatures drop.
Duct Assessment & Repair — Alamo Heights
Older Alamo Heights homes often have original galvanized ductwork or aging flex-duct systems that weren’t designed for modern systems. Leaking or undersized ducts can reduce system efficiency by 20–30%. We assess your existing ductwork during installation estimates and quote sealing or replacement as needed.

Neighbors, Not a Franchise Honeycomb Heating & Cooling is locally owned by Brandon Caputo, who came up through San Antonio’s construction and home services trades.

Flat-Rate, No Surprises — Especially on Cold Nights We give you a firm price before touching a single component. No hourly billing that balloons during a cold snap. Whether it’s a $105 flame sensor clean or a $638 gas valve, you see the number and approve it first. Most Alamo Heights repair visits are quoted on the spot.
Alamo Heights Winters: Short, But Unforgiving The 78209 area averages just 22 days per year below 40°F, but when temperatures drop, they drop fast — overnight lows near 28°F are documented multiple times per decade. Systems that have sat idle since February are not ready for that. Our pre-season tune-up in October is specifically designed for furnaces that spend 9 months doing nothing.

A note on Alamo Heights home types: The neighborhood’s 1940s–1960s craftsman bungalows and Spanish colonial homes often have original galvanized or flex-duct systems that were sized for the heating equipment of that era. Upgrading to a modern gas furnace or heat pump without assessing your ductwork first can leave you with a high-efficiency system delivering low-efficiency results. Honeycomb always includes a duct assessment in your installation estimate — and we quote duct sealing or replacement honestly, only recommending it when we can show you data that supports it.
Heating FAQ alamo heights
Why do older Alamo Heights homes need furnace service more often than newer San Antonio builds?
Most homes in Alamo Heights (78209) were built between 1940 and 1995. Gas furnaces from this era were designed for continuous seasonal use — but in San Antonio’s mild winters, these units often sit dormant for 9–10 months before being switched on. That dormancy allows heat exchangers to develop micro-cracks, ignitors to weaken, and draft motors to seize from disuse. A pre-season inspection every October catches these issues before the first cold front arrives and every HVAC company in the city is booked solid.
Is my Alamo Heights home’s original ductwork compatible with a new heat pump system?
Many Alamo Heights homes have original galvanized or flex-duct systems designed for gas furnace air volumes. Modern heat pumps move air differently — at lower temperatures but higher volumes — so undersized or leaking ductwork significantly reduces efficiency. Honeycomb performs a duct flow assessment during every installation estimate and can quote duct sealing or replacement as part of your system upgrade. We won’t sell you a new system that underperforms because of a duct problem we didn’t tell you about.
What causes my Alamo Heights furnace to blow cold air during a South Texas blue norther?
The most common causes in 78209 homes are a tripped limit switch (often from a clogged filter accumulated during long dormancy), a failed ignitor weakened from months of disuse, or a cracked heat exchanger — more common in furnaces that have gone through repeated freeze-thaw cycles over 20+ years. Aaron or Steven can diagnose the exact cause on a same-day visit and give you a flat-rate price before touching anything.
How much does furnace repair cost in Alamo Heights TX?+
Heating repairs in Alamo Heights range from $105 for minor fixes (igniter replacement, thermostat re-leveling, fuse replacement) to $445–$638 for mid-range repairs like capacitor replacement, flame sensor, or gas valve issues. Major component work such as control boards or blower motors runs $1,165–$2,000. Honeycomb quotes all work at a flat rate before starting — no hourly billing, no surprise fees added at the end of the invoice.
Should I replace my Alamo Heights gas furnace with a heat pump given San Antonio’s climate?
For most Alamo Heights homes, a heat pump is the more efficient long-term choice given San Antonio’s mild winters — the 78209 area averages only about 22 days per year below 40°F. Heat pumps operate at 250–300% efficiency in temperatures above 35°F, far better than any gas furnace. However, homes with existing gas lines, older ductwork sized for high-temp furnace air, or structural constraints may still benefit from a quality two-stage gas furnace. Omar Castilleja, our 27-year licensed technician, walks every Alamo Heights homeowner through both options honestly — no pressure toward the more expensive choice.
