Meet Jason Giandalia

I also own Minnesnowii Shave Ice. You may have seen my shave ice trucks around the state at fairs, festivals, and at our notable Minnesota State Fair. Customer service is number one for me with Minnesnowii and I bring the same service, energy, and passion to Gray Duct Technologies.

Born and raised in Minnesota, I enjoy being active outdoors in all seasons. Few of my favorite things to do: reading, working out, learning, spending time with friends/family and traveling.

What sets Gray Duct Technologies apart?

We understand how frustrating it can be when looking for a reputable and trusted air duct cleaning company. We will educate you on our process, answer all questions, show you photos: before, during, and after the job.

We are fully licensed, insured, and certified! When you buy or sell a home, you may work with a realtor who is licensed. When you go see a medical doctor, you expect them to have a medical license as well. The same should go for when you are hiring an air duct cleaning company. Make sure you place your home in the hands of a certified technician.

Some companies will clean a limited number of vents, charge per vent, skip the trunk lines, skip the furnace, skip the blower wheel, and tell you your system was cleaned. That is not the correct way to clean. If we see asbestos or mold, we will refer you to the appropriate company to resolve these issues as indicated and return to clean after.

Gray Duct Technologies is a proud member of NADCA: National Air Duct Cleaning Association as well as The Chimney Safety Institute of America.
