Duct Doctor responded to my email inquiry within an hour, and came to clean my dryer vent the next afternoon! I... couldn't have asked for a better response time. The technician was on time, professional and very respectful. It was a great experience start to finish. I will definitely use them again in the future.read more

Once again quality service was provided. I had such great results after the first cleaning that I decided to have a... second home done as well. The before and after pictures are night and day in comparison. Knowing there had been so much dust and dirt in the vents makes me want to have this service done annually.read more

Zach and Ben were great. They were on time and professional! Put floor protection down and communicated the whole time... with me and my wife. They were efficient and a pleasure to have in my home. Would recommend them as a crew and the service as a whole 10/10!read more

Left dust and debris around. Didn’t reseal the air handler fully. Nice guys but not sure it was worth the high price... and disruption to the system. Minimal dirt removed after 20 years—I guess most is caught in the filters. If I see the need, maybe just vacuum from the registers. **After I left this review the company offered to come clean up, fix the unsealed ducts and a small refund ($50). A nice gesture, so upgraded to ***read more

Some of your guys were working at a neighbors house so I went over to talk to them about cleaning out a bath vent I... have that birds had been nesting in. Royd came right over when done on other job and took care of cleaning out the vent for me. He was very knowledgeable, nice, courteous and thorough. Price was great as well. I would highly recommend your companyread more

Amazing work! The crew was extremely time efficient, very clean(they wore shoe booties), they were in and out before we... knew it. They left no mess behind as well. Our ducts were extremely dirty before they came so the before and after photos looked unreal. The entire crew was very professional. I highly recommend Duct Doctors to anyone! I’ll be referring all my family and friends to them!read more

I was referred to Duct Doctor of Baltimore by a client. It’s been a few days since the service men came to clean our... system and I’m still feeling impressed by their thoughtfulness and professionalism. These guys came in put their booties on and got to work. They were willing to answer any questions either my wife or I had about the process. They even pulled out a vacuum and cleaned up after themselves. I’m so happy to have them work on our house. We really needed their help.read more

Yesterday, I employed Howard Scher and his team in Baltimore to clean the 2 HVAC units in my house and an additional 2... units at my office. His team showed up exactly when they said they would be there. The team consisted of 3 young men who were polite, professional, educated in their field and did a terrific job of keeping our buildings spotless. Once they were finished, they left the locations just as clean as when they arrived. The job was completed in one day and I could not be more pleased with the results. Our environment(s) is much cleaner, and we now have the confidence that our air quality is healthier. I would recommend Howard Scher's company to anyone who is need of this service, both commercial or residential – and whether you know it or not, that’s you.read more

Absolutely the most friendliest and knowledgeable technicians in the business. I have had several duct cleanings in... the past, but this was the best experience so far. They showed me pictures of the ducts and the vacuum system was incredibly strong. Would definitely recommend without hesitation. The owner Howard called after the service to see my experience and to see if everything was up to my liking. Love this business!!!read more
