Last winter, our gas furnace just wasn’t keeping up. Although the outdoor temperature was especially cold, dropping down into the drawback digits, I expected better from the gas furnace. Adjusting the control component didn’t seem to make much improvement. The beach house felt chilly & the temperature varied from one room to another. I also observed some unpleasant aromas in the beach house & a worrisome amount of dust blowing around. When I googled our complaints online, I suspected that our duct method was to blame, but everything I read pointed toward holes & possible leaks at the seams. I then searched around for an Heating, Ventilation, & A/C supplier who specializes in a full range of duct services. I wanted a professional who would be able to give accurate duct testing & handle any necessary repairs. I looked for a supplier that was certified in Aeroseal duct sealing. When the specialist came to the beach house & maintained & maintained the air duct, he found that nearly 30% of our heated air was escaping through a variety of flaws. Along with holes & cracks at the seams, there were sections of the method that needed to be completely replaced. I was thankful for all of our research, because the supplier I chose included a sheet metal fabrication shop. They were able to custom design, fabricate & install sections of the air duct. They then used a component to inject pressurized air laced with polymer particles into the system. The process was guided & monitored by a computer to ensure the right amount of adhesive was introduced into the system. As the air leaked out, those particles clung to the edges & created an airtight seal. The whole process took a couple of minutes & created no mess or destruction. The difference in the performance of our gas furnace was instantly noticeable.
