I paid $848 for air duct cleaning and furnace maintenance. The job seemed to go fine but the next morning, my house was 60 degrees although the thermostat was set to 72. I tried adjusting thermostat settings, making sure the power to the furnace was on, etc. I had never had any problems with the furnace before for several years. I called the company and spoke with a supervisor who argued with me about whether they had caused the furnace malfunction. He repeatedly questioned me about whether the furnace worked when the technician left (yes, the furnace would turn on for about a minute at a time, but clearly was not fully working because my house was 60 degrees the next morning). He was very focused on getting me to "admit" that the broken furnace was unrelated to the maintenance done the day before. I did not make any "admissions" on the phone because a lot of these companies record all their phone calls. I felt like he was trying to get me to say something to use against me, rather than helping me solve my problem. The furnace has never had problems for several years until the day they did "maintenance" on it, but the supervisor was telling me that it "might be totally coincidental". I'll let you use your common sense about that one. The correct response to this would have been to just send someone to my house without debating on the phone with me. On the plus side, the technician they sent to fix the problem did a good job. It was apparently just related to a dirty air filter. But after paying about $400 for the furnace maintenance portion, I would have hoped they would have pointed out the day before that the filter was dirty and I should change it. It is a little questionable to me how good a job they did on the "maintenance", since I do not know much about furnaces. After this "maintenance" I had a minor emergency because I was worried my pipes would freeze and I had to take time off of work to get the problem resolved. Even though the person they sent to fix the problem was good, I did not appreciate having to take time off of work and being lectured to about how the problem was probably my fault. I will not use this company for anything in the future. read more

Josiah came and cleaned our many ducts and did an outstanding job! Truly, it was a challenge, and required a tremendous amount of care and patience., both of which he exhibited. He is a bright, pleasant and dedicated employee and hopefully will have many opportunities to advance. The customer service from the office was mediocre, at best. The appointment was originally and deliberately set for Sat. am from 8-10, and I was called Friday late afternoon, asking if I could change it to 11-1pm because of their need to reroute the truck for better efficiency. (Not sure why that was my problem, but clearly it became mine.) I wasn't pleased, but offered an 11-12 time frame. I was told that was ok, but at 12:15, when I called to find out the status of our appt., I was told that they'd be there closer to 1pm. At 1:20, Josiah came, and started to work. The company offered me a 10% reduction in my cost, which didn't really make up for the inconvenience nor the fact that my entire day was shot. I guess I wonder why you schedule your drivers all over town, rather than having a flow of work that makes sense? So, the cleaning was worth it (we just finished extensive tile and counter top replacement) and lots came out. But, if you do book them, I'd suggest you be prepared for dedicating an entire day to the event. read more

The service itself was great, the ducts are clean. However, I got a call from the tech saying he'd be there between 2-2:30pm with an estimated 3-4 hours for the service. He arrived at 4:30pm and stayed until 10pm. It was a big inconvenience for me because it messed with my evening plans. Please call with accurate arrival times and don't make people wait around. read more

Shout out to our service tech. Airfornia! We were greeted with kindness and Airfornia worked very hard, explaining things along the way. Our house felt clean once the service was completed. read more

Airfornia was on time, professional, and did an awesome job! Would recommend and use again.

I thought I would try Denver Ducts. I was not very thrilled left ducts unscrewed was supposed to do before and after picture nothing yet. I found cobwebs and other dust after. see pictures also a wimpy vacuum was used. Don't waste your money read more

Justin came out to clean our air ducts. He was very personable, polite and energetic. After he showed us how dirty the furnace was, we decided to clean it as well. When the work was done he emailed 52 pictures of the job. The entire job cost $500. That's expensive but we hope it will be worth the cost if it helps to improve our health. Justin worked hard while he was here and we were satisfied with his work. read more

Working with this organization was wonderful from the first moment. My call was answered immediately by a human. I was able to get a Saturday appointment 2 days later. The technician arrived on time. He worked hard the entire time he was there, and explained his process when asked. It was a wonderful experience. read more

Caleb Becker did an excellent job with our duct cleaning. As I ask questions along the way, Caleb was able to explain all that was going on. He also work quietly and we did not know that he had done a particular part of the job so we asked about it and he showed us what he had done. I would choose Denver Ducts again. read more

On time, very professional, and a pleasure to do business with. Josiah is a huge asset to your company!

Justin was on time, friendly, explained the service in detail with the add on options, completed the work in an efficient manner and provided pictures of all the serviced areas. read more

Caleb was friendly, professional, and a hot to work with. Would definitely recommend.

Never had ducts cleaned before and therefore have no comparison but had lots of debris to clean up after the Denver Ducts technician left. Multiple places where we have ceiling vents clearly had piles of dirt, dust, and other debris piles on the floor. This was fairly disappointing considering the cost. I would not have expected to cleanup after a company that I paid to clean our duct work. read more

They arrived on time, but when they plugged into my outlets (they tried many of them), it kept tripping our circuit breakers. He called us manager who said they would contact me and send out their truck that had its own generator. I never heard from them again. Left several voicemails but nobody bothered to get back with me. read more

Denver Ducts - had FULL works, duct and HVAC cleaning, including AC and Heating Units. $813.00. Technician took apart the entire heating fan, motor, and assembly, used a corrosive liquid to clean in my garage, including burning himself (arm) in process. Unable to turn on system when done as interior painting was in process - did not want to suck in the paint into newly cleaned ducts. Next day had I had a scheduled thermostat install ($150.00) - swap out old programmable for new non programmable. When technician arrived system was down. He discovered needed a NEW MOTOR part (no doubt from previous days washing, corrosive cleaning). Up-charged $899.00. Complete scam. When I asked about the prior day cleaning and that motor work prior to cleaning, seems like cleaning had something to do with motor failure - especially in light of tripped breaker every time the 2nd guy tried to start HVAC. No response from onsite technician, but "supervisor" would call. I was trapped. They broke furnace motor, then scammed a replacement, and no one has ever called back and discussed why my thermostat install went to a motor replacement. read more

Got a mailer and saved it because we wanted to get our ducts and area rugs cleaned. Set up an appointment online, received a confirmation text message the day before, then today, nobody shows up. Apparently, if you schedule an online appt, it allows to overbook in the system. I get it, but that's not my problem, it's about the customer. I called to let them know and supposedly they called me yesterday and left a voicemail (didn't happen, I checked). The offered to come tomorrow and do it, I declined. It was more like "OK, we missed the appointment. So what, we can do it tomorrow." When you want to support small/medium sized businesses and then they react/respond this way for a first time customer I can only imagine what they would do to a repeating customer. Either train/empower your front line customer service representatives to respond to concerns in a more empathetic way, or find people who actually care about customer concerns. I really wanted to support, but I can't do business with business who have employees who operate with a lack of empathy and compassion for paying customers. read more

We had a great experience with Denver Ducts! They were on time and efficient with the whole house cleaning. For my single furnace home it took about 1 1/2 hours. The before and after pictures that they send you are eye opening. There was just all types of junk in my air ducts. The home was built in 1973 and apparently never had a cleaning. The dryer cleaning is a must! There was so much lint that could have started a fire. Thank you for cleaning my home and making it safer! read more

I found a special on Nextdoor for duct cleaning and called to take advantage of it. The technician got here right on time, put on shoe coverings, work gloves and a mask. It took about 2 hours, he left everything neat and clean. My dryer was put back after that vent was cleaned. I was very happy with the service and got before and after pictures about 4 days later. I recommend Denver Ducts. read more

This company is awesome. Professional , arrived on time, and cleaned up any mess they made. Will definitely use them again

I had previously posted a 1-star review for DenverDucts Corp, based on issues with their customer service and the furnace cleaning service we purchased, but I am back to revise my review. After posting my review, I got an immediate response by email and by phone from their General Manager Tim, who helped address my concerns. I had not gotten pictures of the before/after of the vents for many weeks, even after contacting them to request them a second time. Tim stated it was an issue of the wrong email address, and he had resent the photos to me even before I received his call. My other issue was with the Furnace Cleaning/Duct Sanitation service I had purchased on special for $150. I had assumed a furnace cleaning would be a true cleaning of all the components like flame sensor, ignition, blower, exposed parts inside the cabinet, etc. That was not the case - the furnace cleaning service provided is only vaccuuming the blower and checking the furnace filter. Nothing else in my furnace was cleaned. The GM informed me that they have a separate, more involved service for cleaning the furnace like I had anticipated, but it is more expensive based on those added services. Nowhere on the site was the furnace cleaning I ordered described, so I guess this is partially my fault for not asking more questions. I've since hired another company to do a true full service cleaning and inspection. Just be mindful that if you are looking for furnace cleaning from this company, be sure to ask what is included in the service. read more

Disorganized like a pig sty. Communication, problem solving skills need to improve. The only good part about the company are their bold promises but even with that I wouldn't ground myself here. read more

As the owner of a plumbing service company I knew what I was looking for in a duct cleaning company: honest pricing, respect for my home, thorough cleaning, and professionalism. I received honest pricing: $350.00 for all duct cleaning, and a sanitizing treatment. I had to remove and replace all the ceiling vent covers myself to prevent a surcharge for each vent cover. Furnace burner cleaning was not included. The technician did not display professionalism or much concern for my home. He came in and out of my home in his dirty tennis shoes multiple times, left his dirty coat on my carpet, and then laid filthy furnace filters on my living room carpet to show me how dirty they were. His appearance and demeanor were sloppy, but he was polite and was able to answer my questions. The hose used had less suction than my own vacuum, (I asked to feel the suction) but the technician stuck a brush down the vents and that apparently dislodged stuck-on dust. The before and after pictures showed that the vents were cleaner afterward. The exterior of my air intake vent covers were still dirty when the job was done. I asked about that and was told it wasn't included: disappointing, but fair enough. I doubt I'll use this company again, but I believe my vents are cleaner and I received what I was told I would. While nothing about this experience was impressive, and I had to clean up after the technician, it met my minimum expectations. read more

The tech was superb. He was professional, courteous. He took photos before and after when he was done. This was great. We had not had this done for a few years, and it was really needed. Jonathan arrived in a timely manner. He performed the job well and explained himself as he was going. There was a little confusion about the scheduling time, However, when the appointment was changed from morning to afternoon- Jonathan showed up right on time. We would use this company again in a flash- especially if the tech would be Jonathan. read more

I will be painfully honest....At first I was hesitant to use Denver Ducts. I spoke to several local companies in Northern Colorado; some claimed to be "certified", some claimed to have the most expensive and newest equipment, some cautioned me from using any company that gives me a blanket estimate of $XYZ to do my whole home. After interviewing those companies by phone and hearing them out, I thought it only fair to also speak to the style of company that they were cautioning me against, which appeared to me to be..... Denver Ducts. To make the story short, I am a property manager with lots of experience needing, interviewing and then hiring service companies. After asking lots and lots of questions, I decided to try Denver Ducts at one property. I figured if I see how they work, I will know if they are worth the money they are asking vs. 2 and 3 and 4 times the money that their competitors were asking. They ARE WORTH EVERY PENNY. I have now used them 3 times. They are thorough. Whatever time they figure to do your home, if they need to take more time to get the job done right, they take the time and do it without asking questions. I feel that the price charged was worth every cent considering the time it took, the amount of labor involved and the "dirty" "yucky" nature of the task. I will use them again! read more

DDC Came out prepared for battle against dust and dirt, limited to ductwork. Their tech was experienced, professional and cordial. We will have them back in the future. read more

I've never had a finer experience with a company than I had recently with Denver Ducts. After getting what seemed like an excessive quote from a company in Boulder a few months before, I caught Denver Duct's offer on a ValPac coupon for about half the amount. When I phoned, I got a live person, not a bot or an answering machine. She assured me that Niwot was still in their service area and got me on the schedule a few days later. The day before the cleaning, they texted to confirm the time window and the day of cleaning they texted me again about a half hour before to let me know their tech was on his way. Luis arrived with pretty sophisticated cleaning equipment mounted in his van that included brushing, washing and vacuuming machinery that the connected by hose to the implements used inside the house. Portable guards kept the hoses from scraping against any walls or furniture. He sealed all the heat vents with plastic before starting the cleaning and was at the house for over three hours. Cleaning included clothes dryer vents where Luis discovered a broken connection during cleaning and promptly fixed it with no additional charge. A couple days later I received email with over 50 pictures in jpeg format of the vent interiors and the process to show before and after results. Absolutely the BEST. I won't use anyone else as long as they are in business. Access photos at https://spaces.hightail.com/receive/SaUIUXYBs5 read more

Great job on my whole-house air duct cleaning. I received before and after pictures and am completely satisfied. I recommend Denver Ducts.

Your technician was pleasant and knowledgeable being careful to use his foot protection in the house. However, when he did the dryer vent cleaning outside, he left a horrible mess all over the landscaping rocks where the dryer vent exhausts. He made attempts to blow it off of the window well cover, but blowing more out onto the rocks. How do you clean a 6 foot avalanche of lint after it's been rained on? Not without a lot of time and trouble for sure. He should have put a tarp down. Now we have been left with a terrible mess. . read more

These guys are amazing! Prompt, thorough, and a great value! I recently purchased a pre-existing home where the previous owner had dogs and probably never thought about her vents and ducts. Everything was cleaned, sanitized, and now I feel better about running air through all our vents! Love the before and after photos so you can see what was done! Thanks Denver Ducts! read more

Dara did a thorough job inspecting our furnace and vents. Service was exceptional and very professional. I would recommend him and his team to anyone that needs furnace repairs/replacement/clean HVAC system, etc. These guys are extremely professional and kind! Highly recommend! read more

Great company! Before and after pics of the vents and did a thorough job. Highly recommend!

Although there were a few issues, I was so impressed with the owner and his willingness to correct the issues. He was super responsive and even came to my home to re-light a pilot light at 7:00 at night so I could have hot water! Our ducts are clean, all vents were replaced correctly and the pictures were proof that the previous owner never cleaned the vents in the 5+ years he'd lived here. In addition, our furnace and water heater are very old, yet the owner had decent knowledge regarding both. So, despite the scheduling snafu for the first scheduled visit, and the loss of my lit pilot lights both times, the willingness to correct these issues made me a happy and return customer. We will use Denver Ducts Corp to have our ducts cleaned in a couple of years!! Thank you for the excellent customer service!!! :) read more

They did a great job! Very responsive and professional. Easy to schedule with text updates in advance of the appointment. Kevin, the tech, was friendly and thorough. Well priced. Followed up with before and after photos. I would recommend. read more

Called to get an estimate as their advertising says $249 any size house, when I called they asked me if I have 2 thermostats and when I said yes she said that would be another $100. I asked her to explain why but she really could not so, fine I agreed to $349. Then she said we would have to take off all the vent covers which my husband spent over an hour doing so. A guy came to clean the HVAC the next week and told us it would be $499, because we have 2 furnaces. Umm, no you quoted $349. I spoke with the manager who said she would now do it for $449. No, typical bait and switch!! Then the guy asked to see our furnaces which he could clean for us. Mind you my house is 2 years old. He shows us a picture of a filthy furnace and told us he could clean our furnace for a discounted price. I told him, no thank you. We had another company come back 2 weeks later to look at the furnace and the guy took 10 minutes to clean both furnaces which he said were totally fine and clean... which leads me to believe this guy had someone else's pictures on his phone. Beware, not honest and ethical in my opinion. read more

I am not sure why Denver Ducts has such a high rating. I paid a lot (although not the top price of $600) and got very little. I think they spent more time taking pictures than cleaning. 27 befores and 2 afters is my guess since those were the what looked dirty and nots so dirty, respectively While they did open vents and do some cleaning and they sprayed something to disinfect since I could smell it two days later. What I paid for was duct and furnace cleaning. The furnace was not cleaned and even with a new filter right next to the furnace they didnt even change the filter. The furnace was very dusty outside and in, we had to clean ourselves. All the wall vent covers were still dirty on the outside. I think the only covers they touched were the floor covers that just lift off. I would not recommend this service. read more

I received a coupon in my Valpak flyer for duct cleaning a whole house with one furnace for $249. That was a good price, so I called to make an appointment. It wasn't until the very end of the conversation that I was told that I would have to remove all the vent covers up on the walls or ceilings first, before the techs got there. If the techs did them, it would cost me $10/vent. I have 11 upper vents, to my total price would've been $369. So, not such a good value for me. I cancelled the appointment and made one elsewhere. read more

This was a very pleasant experience with DDC. From the scheduling the appointment to keeping me informed on the status of the job was outstanding. The work was done correctly. The employee doing the work was great. He explained everything he was doing and was very professional. If I could I would give them more than five stars. Great people great job and cost was great also. read more

Excellent and efficient service. Arrived on time. Great communication. Josiah is who came to my home and I absolutely loved him. He knew what he was doing and was very professional. I am going to request him for all future service. read more

The cleaned our HVAC system and cleaned our ducts. Max was professional and kept me informed on issues and resolved all of them. Very satisfied. read more

If I could give a half a star, i would. This company came to my home to "clean" my ducts along with my dryer vent, little did i know they were charging me an extra $349.00 to service my furnace when i said i did not need so done and my wife witnessed me say no. Leo the person cleaning the ducts showed up 30 minutes early without warning, then hustled to work without even me talking to him about the main reason they were at my home which was to make sure my dryer was working correctly which i stated on the phone. He then cleaned half of the house, told me he was done and started packing up when i alerted him that he had missed 4 of the rooms in the house completely. After that he said he was going to clean the dryer vent which he said he did and did not at all i have found out. While he was talking of the dryer vent he said he needed help getting on the roof to do so so i pulled out a ladder, helped him up there while he was up there for around 20 minutes, helped him down and he was on his way, he did nothing up there and his company does is not even allowed to have people get on the roof due to insurance reasons. When i called to talk to them about this issue they said they would call back and when they did stated that i was in the wrong for them charging me for the wrong package, said that i was in the wrong about letting him get on the roof, and then tried to charge me to have them come back and probably do nothing once over again. I do not recommend this company to anyone as their service was terrible and the customer service when i contacted them after the fact was even worse. After having the ducts cleaned themselves it did not help with the airflow of the central air system and now i am going to have to hire a different company to do the job even though i have already spent money on what i expected to be a good job. read more
