When a cold front blows in and your heater won’t keep up, Just Call Radiant! Austin doesn’t stay chilly for long, but when those hard freezes hit, you need a furnace that starts fast, runs safely, and warms every room. Since 1999, Radiant Austin has helped homeowners and small businesses get reliable heat without surprises. We show up on time, explain what’s going on without the technical jargon, and give clear, up-front pricing before we begin.
Austin homes bring a mix of older bungalows and newer, two-story builds with equipment in attics. That combo can lead to dust buildup, tired parts, and airflow issues that only show up on the first truly cold night. We zero in on the everyday troublemakers: safety switches that trip, burners that won’t light, or thermostats that won’t cooperate. If your system runs but never feels warm, we look at airflow and duct leaks, not just the box in the attic. For gas furnaces, we check for safe operation and offer peace-of-mind testing so you can rest easy. If you use a heat pump, we make sure it defrosts correctly and that backup heat is ready when temps dip. And because Austin can swing from sunny to freezing in a day, we help you “freeze-proof” with simple steps like protecting outdoor spigots, verifying shut-off valves work, and confirming your furnace is ready before the next cold snap.
If a smart, long-term fix beats another quick patch, we’ll walk you through options that fit your home, your budget, and our Texas weather—no pressure, just facts.
