Combustion Draft Interference Testing — Georgetown TX
Draft interference — when exhaust gases are pushed back into the building by wind, stack effect, or competing exhaust systems — is a safety issue that requires careful diagnosis. ProAir Georgetown tests draft under multiple operating conditions to identify interference patterns and implement the correct solution.
Back-drafting is insidious — it may only occur under specific wind conditions or when exhaust fans in the home are operating. Testing under simulated worst-case conditions (all exhaust fans on, windows closed) reveals intermittent problems that a single measurement would miss.
What's Included
We measure draft under normal operating conditions as a baseline.
We test with all exhaust fans operating and home depressurized to simulate worst-case conditions.
We test for combustion gas spillage at the draft diverter or barometric damper.
Solutions range from barometric damper adjustment to fresh air intake installation to chimney extensions.
We document results under all tested conditions with our recommended solution.
