Ottawa’s Oldest Church Fixes Hvac Issues With Duct Sealing
“It took over a year to find the cause of our heating problem – and less than a day to fix it!” That’s what Mary Martha Hails, the facility manager at St. Alban’s Church said about the Aeroseal duct sealing work that was just completed.“We were skeptical duct leaks could be responsible for the issues we were having with the (new HVAC) system. We were wrong,” said Daniel Carley, the project manager. Aeroseal proved to be the fastest, easiest and least expensive solution. It was a project saver.
Even highly trained engineers are surprised at the role duct sealing plays in the proper overall performance of an HVAC system. Many commercial projects do not even spec in the cost of duct sealing so we find that virtually all buildings we test are losing 20% of treated air – not to mention thousands of dollars in utility costs – through leaks in the ductwork. Aeroseal can quickly fix those leaks, reduce energy use, solve ventilation issues, and increase heating and air conditioning efficiency, all without having to rip into existing structures or otherwise disrupt the regular office operations.

Results
It took the Aeroseal team just a matter of a few hours to seal the entire duct system – without having to disrupt any of the new construction. Leakage was reduced by 92% and the ERV system that wouldn’t work properly is now generating 20% more air than needed at half its power.
