After we had our ducts cleaned and sealed by Kleanmaster, our house has been noticeably cleaner with less dust build-up on our black lacquer furniture. More importantly, they were able to seal off an estimated 64 sq. in. hole in my ductwork using Aeroseal, which is equivalent to about 22% of the airflow my furnace puts out.

Wait, does that make sense?

I was losing 22% of the performance of my HVAC system! That's ridiculous.

We have better airflow in our bedroom now, which means we don't have to close registers downstairs in order to push air to the bedrooms upstairs and we can set our thermostat lower because the house heats and cools more evenly now.

I wasn't able to stay home to watch the process, but my wife's biggest observation was how comfortable she felt alone with the their service team in our home. She normally gets weirded out, but she said the guys were very polite and professional.

Highly recommended.
