Here's the problem. Most of the homes in which we live, and the buildings in which we work, have air ducts that leak air like a cheap pool float. In other words, a lot. For the majority of the modern building era, this was just chalked up as a common problem - one that contractors and homeowners just accepted.
Get comfortable, breathe healthier air, save money and protect the planet with our simple solution. Watch us on This Old House and see what other TV shows have to say about Aeroseal duct sealing. Sealing your return ductwork increases the home's indoor air quality, helping to eliminate dust, allergens, and odors coming in from unconditioned spaces.
We connect our proven technology to your home's heating & air system to distribute the sealing formula.

We connect our patented technology to your home's heating & air system to distribute the sealing formula.
Cracks and holes in your home's air vents and duct system allow heated and cooled air to escape before reaching your rooms. While even new ductwork may look professionally installed, each metal on metal connection that has not been properly sealed is a point of leakage. This results in leaving you with stuffy, uncomfortable rooms and wasted energy.

I worked for this company a few years ago through a temp agency. Before I was hired they had all these positions I could potentially transfer into after temp the job assignment was over, but as soon as they met me or Dan Crowe finally met me these positions all of a sudden disappeared. I was accused of placing a virus on a laptop and taking a laptop home on my 3rd day there by Amit Gupta.

I was told in not so many words since my personality did not match the company after giving me a personality(the last week of my job assignment) test all of a sudden I was not good fit and my temp job was terminated. This was not what I was told when I initially spoke with temp agency that assisted in helping me get the job. The temp agency was awesome and was upset when I was lied to about my job ending and the positions no longer being available. I do hope that they treat their other temps better than I was treated.

Extremely unprofessional company. I went through several rounds of interviews and received very positive feedback every step of the way. After investing several hours of my time into their ridiculous interview process, they gave me a generic "best of luck with future endeavors" email and refused to tell me what went wrong despite several polite inquiries asking for honest feedback.

Proud to be a partner with this amazing company! We have sealed hundreds of our customers home down to below 2% duct loss with an average ROI of 3-5 years. Have not had a single dissapointed customer to date.

In theory this made a lot of sense. Practically it made no difference. It was a big disappointment. I'm a very particular person, I read all the digital reports that they showed me That proved it worked. But when it came down to energy costs, ability to heat and cool my house more effectively, it made zero impact. I wish I could get the money back and the time I lost.

Kathy Dizek is absolutely amazing! She has always been super helpful with any issues we have and she gets everything resolved in record time. You can tell that she loves her job because she always goes way above and beyond to make sure her AeroSeal dealers know about all aspects of the system from maintenance programs to home shows. She is the best!
