Heating Output Stabilization — Georgetown TX
Fluctuating heating output — where your system runs but delivers inconsistent warmth cycle to cycle — often points to control board irregularities, a failing flame sensor, gas valve issues, or a thermostat that isn't maintaining accurate call signals. ProAir Georgetown traces unstable output to the component level.
Inconsistent heating is frequently misdiagnosed as a thermostat problem when the root cause is a failing flame sensor, intermittent gas valve, or control board issue. We test the full control sequence — from thermostat call to burner response — to find where the inconsistency originates.
What's Included
We test the furnace control board for error codes, relay failures, and intermittent faults.
A dirty flame sensor causes the system to light and immediately shut off — a classic instability pattern.
A gas valve that doesn't open fully or consistently causes output variation from cycle to cycle.
We verify the thermostat is generating a clean, consistent call signal and not introducing intermittency.
We observe multiple heat cycles to characterize the instability pattern before diagnosing the cause.
