"Marcos was our technician and he was very courteous and professional. He not only cleaned our vents but cleaned the closet where our washer/dryer resided (which is a very tight space). Marcos was very conscious about removing his shoes before entering the house and cleaning up after all of the work. He also installed cages over our outside vents. I would definitely recommend Mr. Duct and will be hiring them again for our next cleaning. Thank you Marcos!"

"The AWE plumbers did a wonderful job replacing the broken connection, re-routing the pipes and repairing everything. They also installed new faucets in the basement. I'm very pleased with their capable professional work."

"This process went very well. As a matter of fact, to try to help me out in this process, he tried to troubleshoot with me over the phone so I could potentially make the fix myself. He made an appointment to come out to see me, I believe the next day and quickly fixed my freezer. He found that it needed an inverter board, which he happened to have and was able to do the install. Very polite, quick, clean and yes, I would definitely use again (hopefully I won't have too though)."
