Cold snaps hit Cibolo fast, and that’s when hidden furnace issues show up. Radiant’s licensed HVAC techs know the mix of systems here: gas furnaces in newer two-story homes with attic installs, heat pumps paired with electric strips, and light-commercial rooftop units along FM 1103. We start with safety and performance by verifying gas pressure, checking flame signal and ignition, inspecting heat exchangers for cracks, and testing carbon-monoxide levels. Tight, energy-efficient homes around Cibolo need proper combustion air and sealed return ducts; we measure static pressure and temperature rise so your furnace isn’t short-cycling or starving for air.
Attic installs, which are common here in Cibolo, face unique local challenges. When a blue-north wind drops temps, poorly insulated lines and leaky returns can make second floors drafty and uneven. We seal up air leaks and adjust the airflow, clean the furnace’s drain line, and make sure the safety shut-off switch works, so water doesn’t overflow and damage your ceiling. If your blower, inducer motor, or capacitor is failing, we stock quality parts and set clear expectations before any work begins. For systems near end-of-life, we size replacements based on your home’s envelope and actual heat load, so rooms heat evenly without overspending on gas or electricity. Want steadier comfort and lower bills? We’ll pair smart thermostats, filtration upgrades for cedar season, and duct improvements that actually move the needle.
Whether you’re near JBSA-Randolph or tucked beside Cibolo Creek, we treat your home with respect—floor protection down, options explained, and pricing up front. When it’s 30° and dropping, you deserve a furnace fix that’s done right the first time.
Radiant is San Antonio-proud and ready when the temperature turns. For swift, transparent furnace repairs that stand up to Cibolo’s weather, We Answer the Call.
