Air quality
Duct testing
Leaky ducts can waste a large share of the air you pay to heat and cool. Testing shows exactly how much.
What duct testing measures
We pressurize the duct system and measure how much air escapes. The result tells us whether the ducts need sealing, repair or replacement, and gives you a baseline to compare after the work is done.
Signs your ducts leak
- Rooms that never reach the set temperature
- High bills compared with neighbors
- Dusty rooms soon after cleaning
- Ducts in a hot attic or crawl space
