Furnace Repair & Heating Service for Security-Widefield Homeowners
Security-Widefield is a census-designated community located south of Colorado Springs, adjacent to Fort Carson. With a combined population of approximately 38,000 residents, it is one of the largest unincorporated communities in El Paso County. The area developed primarily during the military expansion of the 1960s–1980s, which means the majority of homes were built between 1965 and 1995. This housing stock creates a distinct pattern of furnace service needs — many homes contain mid-efficiency furnaces (80% AFUE) that are 20–30 years old and approaching or exceeding their expected service life.
One of the most common service patterns we see in Security-Widefield is the "inherited furnace" scenario. A military family PCS transfers to Fort Carson, moves into a rental or recently purchased home, and discovers that the furnace is not performing well. Often, the furnace has been "repaired" multiple times by different contractors, but no one has performed a comprehensive altitude calibration or checked the heat exchanger for cracks. Our approach in these situations is to start with a complete system evaluation — not just fix the immediate symptom — because addressing the root cause prevents repeated service calls and potential safety issues.
Security-Widefield Furnace Failure Modes by Building Era
Heating demands and failure patterns in Security-Widefield vary significantly depending on the age of your property and existing ductwork infrastructure.
1960s–1980s Homes
Common in established Security-Widefield neighborhoods with 80% AFUE natural draft furnaces. Key failures: cracked heat exchangers from altitude thermal stress, faulty pilot assemblies, rusted draft hoods, and uninsulated ductwork causing 25–35% heat loss.
1990s–2000s Homes
Mid-era Security-Widefield subdivisions with mid-efficiency forced-air units. Primary issues: failed igniters from thermal shock at 5,850 ft, flame sensor oxidation triggering lockouts, and weak blower capacitors.
2010s–Present Builds
Newer Security-Widefield developments with 95–98% AFUE condensing furnaces. Main issues: uncalibrated gas valves (builders skipping altitude derating), condensate drain freeze-ups, and pressure switch errors.
Why 5,850-Foot Elevation Changes Everything About Your Furnace
At 5,850 feet, Security-Widefield requires a 23.4% BTU derating for all gas furnaces — nearly identical to Fountain but with slightly different conditions due to the community's terrain. The area is relatively flat, which means less microclimate variation than mountain communities, but winter winds from the south and southwest can create significant wind chill factors that increase heating demand. The proximity to Fort Carson also means that many homes experience turnover as military families rotate through the area, and furnace maintenance history can be inconsistent or unknown.

Our 5-Step Altitude-Calibrated Diagnostic Protocol for Security-Widefield
Every furnace service call in Security-Widefield follows an objective, 5-step engineering process to diagnose root causes and guarantee safe operation.
Gas Pressure Testing
We measure line pressure and adjust manifold pressure to high-altitude specs for Security-Widefield's 5,850-foot elevation (~3.1–3.2" WC).
Orifice Verification
We verify orifices are resized for the 23.4% BTU reduction. Sea-level orifices are replaced with high-altitude drill sizes.
Combustion Analysis
Digital probes measure CO (PPM), O₂ %, CO₂ %, stack temperature, and efficiency to confirm clean burn.
Airflow Audit
Lower air density at 5,850 ft reduces heat capacity. We measure static pressure and adjust blower speed for ideal temperature rise.
Heat Exchanger Inspection
Optical cameras inspect exchanger cells for micro-fractures, seam separation, or soot from miscalibration.
What We Know About Heating in Security-Widefield
The Security-Widefield area includes several distinct neighborhoods with different characteristics. The Security area along Security Boulevard and surrounding streets features homes from the 1960s–1970s, many with original ductwork and aging furnace infrastructure. The Widefield area near Widefield Park and along Fontaine Boulevard has slightly newer construction from the 1980s–1990s. Both areas share common challenges: aging infrastructure, inconsistent maintenance history from tenant turnover, and furnaces that may have been repaired by multiple contractors over the decades with varying levels of altitude expertise.

During severe cold snaps in El Paso County, sub-zero temperatures can freeze household plumbing within 4 to 8 hours of heating loss. If your furnace shuts down in Security-Widefield, perform these immediate steps:
- Verify Thermostat Power & Mode: Ensure the thermostat screen is illuminated, set to "HEAT", and the target temperature is set at least 5°F above ambient room temperature. Replace dead batteries if applicable.
- Check Air Filter Condition: A heavily clogged filter restricts airflow, tripping the furnace high-limit thermal switch and shutting off gas burners. Replace dirty filters and power-cycle the furnace at the service switch.
- Inspect Exterior PVC Vent Pipes: For high-efficiency condensing furnaces, inspect external side-wall PVC intake and exhaust pipes for ice caps, drifting snow, or bird nests blocking airflow.
- Protect Plumbing Pipes: Open kitchen and bathroom cabinet doors under sinks along exterior walls, turn faucets to a slow trickle, and open all interior room doors to circulate warm air.
- Call (719) 602-8787 for 24/7 Priority Dispatch: Contact our local dispatcher immediately. Our technicians are on standby for Security-Widefield with typical arrival times under under 75 min.
