Bob & Donna P.

“Thank you for being so neat and clean. We will certainly recommend your service to others.”

Sohail G

“Thanks again for your honest appraisal of my home duct status. I was impressed by your firm’s integrity and will share this experience with my colleagues in real estate.”

Zdenka F.

“This is to thank you for recommending Duct Diagnostics to come and look at the air conditioning ducts at my house after the recent water damage and re-construction.

Michael Keller came to do the inspection and found the ducts in good order, with no special cleaning necessary. The service was performed at no charge to me and I want to thank you for recommending them. They are obviously a very honest outfit.”

Carolyn P.

“Your technicians were extremely professional and well informed! It was a pleasure doing business with Duct Diagnostics!!”

Neena N.

“Duct Diagnostics cleaned the ducts in our home. They were efficient and professional and did a wonderful job.”

Donna W.

“I am overjoyed with the work done this week by your team. I now have a completely different experience of being in my home. Whereas before I would truly dread certain areas of our home, now the air in each and every room is clean.

For 18 months I have been scratching and sneezing in my own room – essentially dreading the nights. I now love to be in my room, I sleep through the night, and I feel healthier. Your method is far more effective than my allergy medicine!

Your team was extremely professional and careful in our home. I think that they left the house cleaner than when they arrived through their efforts to be meticulous. The knowledge of the men on your team was quite impressive. I trusted them with the heart of our home, and they had the skill and precision to execute a very intricate procedure.

Our heating system too has become far more efficient through your method of cleaning the ducts, adjusting the dampers and checking the direction of the grates. Rooms that were freezing cold now are warm. I shudder to think about how much money we previously had wasted.

For someone such as myself with severe allergies, the ability to breathe fresh clean air is totally uplifting to body and spirit. Your team did such a great job, that I would be thrilled to recommend your service to anyone. This is the greatest thing that has ever happened to me.” – Lisa M.

“Thank your for sending wonderful and professional men. They did a wonderful job!”
