Seal your savings.
Most homes lose 20–30% of their heated or cooled air through leaky ducts. That’s hundreds of dollars lost every year, literally leaking away through cracks and gaps.

Hear From Our Customers
Today I had COIT out to evaluate my air duct system with a new service they offer called Aeroseal. My home was built in 1986, and I wanted to see if I could perhaps improve the efficiency of our home, especially with the latest SRP rate increase. COIT confirmed the appointment the night before, and the crew arrived right on time this morning. [The technicians] did a great job explaining the testing process, and once the system was set up and connected to the computer program, we found our system was leaking 5.5% into our attic. After the Aeroseal process, they got that number down to 0.6%! An 88.7% improvement. I’m so happy I had this done, and I’m quite certain it will help mitigate any cooling loss in the summer. The crew was an absolute pleasure to work with and super professional. Even my crazy dog liked them!
