I called 3 times and left voice mails and it took 3 1/2 weeks to call me back and then its a week until they could complete the duct cleaning!! Completely unacceptable!

I had an appointment. Called to confirm and was told I would get a call 30 min. Prior and still no one showed up. Then I kept calling and couldn't get through. Terrible customer service I would not recommend.

The technicians left a quote after briefly looking at my HVAC & doing a mold test with back turned so I couldn't see. Then left a mess in each room (everything they sucked out of the vent was left next to the vent or on the curb + skipped a room.

The crew arrived within the scheduled time frame that they called to confirm the day prior. They were neat and efficient and cleaned up after themselves as they moved through the house cleaning all of the vents.

I had a great experience with National Duct Masters, specifically Duct City. The technician came to my apartment today and was extremely professional (and thorough!). I would highly recommend them!

For the low price, I did not expect a thorough cleaning. I did expect them to probably change the air filter, examine the vents and the furnace (we do not have air conditioning), ask if there were any problems, tell us what we should expect from our furnace for a house our size. I expected a thorough review, to show us what they found (if vents were really dirty) and their recommendation. I also expected a pitch for their services. They asked how long it had been since we had cleaned the vents and without looking at anything, told us we required a "deep clean." After vacuuming one vent (we have 6) they told us it would be $450 to do the deep clean.
