“They were really good. They took their time. They cleaned the ducts out really well and vacuumed everything up afterward. We didn't have to do a thing but write a check. Oh, I'd give them an A+. They were really great. I mean, one of them, they work together, but one of them worked behind the other and with each other so they were really great. They were there when they said they were going to be there and they explained everything to us. We were very happy with them. It's a service you don't need but once every five or six years so it'll be a while before we use them again. Well, there is some dust but, you know, the regular dust around the vents and everything. They were well dressed; they had a uniform. And they were clean. They were punctual. Actually, they were a little bit early because they told us they would be here at a certain time and we had gone out to eat. And we told them ahead of time that we go out to eat every day for lunch and they were about ten minutes early but they were sitting there waiting for us in front of the house. They didn't come and just say well hell they're not here, let's go. We already have recommended them.”

“I liked how thorough it was. The guy, I can't remember his name, was very knowledgeable. We had a flood in our house and they did the duct cleaning upstairs and downstairs, both of them. I'd give them an A overall. It was good. Very highly to recommend them. Actually, I have already recommended them.”

“I liked that they fixed the problem. They did duct cleaning work for me. I would grade the overall experience with an A. I would be extremely likely to recommend them.”

“I liked that they were very thorough, very efficient and very clean. I was just happy with their service. They did a thorough duct cleaning. I would grade the overall experience with an A. I would be extremely likely to recommend them.”

“The lady that I was speaking to on the phone, because we were out of state, was very helpful. They just did duct cleaning for us. I would grade the overall experience with an A. I would be extremely likely to recommend them to others.”

“There weren't any problems. Air Quality Systems showed up when they said they were going to, and did exactly what we asked them to do. They did duct work cleaning and heating. I would grade the overall experience with an A. I would be extremely likely to recommend them.”

“They are timely and efficient. They did duct cleaning in my home. I would grade the overall experience with an A. I would highly recommend Air Quality Systems.”

“They were just very, very professional. They showed up on time. They were very courteous and kept their appointment. They did a great job. They left everything very clean. It's an A for sure.”

“Air Quality Systems just did a really good job. They did what they said they were going to do. They did the duct cleaning, just a cleaning. I would say A+ across the board. I've already recommended them.”

“I liked the convenience and the quality of the person, etc. They did just the cleaning. It was an A+ overall.”

“I had my ducts cleaned. They were very efficient. They go in, did what they were supposed to do and they left. It's going to be an A overall.”

“I liked the fact that the company came back. I thought it was not clean and they actually returned and inspected it. I mean, the job was done. I'd give them an A overall. They responded back fast and they came back. They were there on time. They knew what they were doing even though I thought they were not. I would recommend them to anyone.”

“I think it was last year. I think it was very good. I mean, it hadn't been done in 30 years so it was time. They were very professional—came in, did their job, fixed some ducts that we had that the tape had come off, did that, reseal them, and we've noticed since that time we don't have as much dust in the house. All through the years we've had long haired dogs, we've had cats, so there's no telling what was down there. I would give them an A overall. We would certainly recommend them. We would call them again next time. We keep, everybody who does a good job, we keep their business card and that's who we call back.”

“They did just duct cleaning. I would grade the overall experience with an A.”

“They were on time. They did what they were supposed to do. Really no complaints. They just did residential duct cleaning. They deserve an A overall.”

“They were very nice. They were courteous and they seemed to do a good job. We haven't had any problems with it. They pointed out a few issues that I needed to take care of. We noticed less dust around the home after the service. I'd give them an A overall. They did a good job and I would use them again. I would refer them to others.”

“They were awesome. They were very professional, and they stopped to explain stuff. They cleaned up after themselves and had really good attention to detail—A+.”

“Air Quality Systems treated my home very respectfully, and they cleaned up very well. They were very tidy about their work, and I appreciate that. I'd grade them as an A+.”

“They were really good. I thought they were fantastic. I would highly recommend them—they were excellent.”

“They were great, and they did an excellent job. The house smelled a lot cleaner after they left. I'd highly recommend them.”

“It was exceptional. The thorough explanation of their procedures really stood out. Great customer service. It was A+.”

“AQS was great. It was excellent, and I'd recommend them.”

“I liked them. They were excellent; I had no problems, so I would highly recommend them.”

“I had my ducts cleaned by them. We had an excellent experience. No issues at all. They get a recommendation from me.”

“They were excellent. I have no complaints with the work, and I would recommend them.”

“They were great. I grade it an A+.”

“I used Air Quality Systems to clean my ductwork. They did everything that they promised in the timeframe they gave me, so everything was good. I'd give them an A+.”

“It was a good service.”

“I guess they did a good job, fine.”

“I'd grade them probably an A.”

“I liked that they quickly finished in one day. I thought they did a really good job. I'd give them an A rating.”

“Their work was fine.”

“I'd give them an A. They honored their quote and did it as scheduled.”

“They cleaned the ducts, but it took them a good amount of time to finish. I had a positive experience, but then again I'm still getting dust in my house. They did do what they were supposed to, so they get an A- from me.”

“I was referred by my HVAC guy, and I've referred them to many people who've had no complaints. They came on and time. I'd give them an A rating.”

“No complaints, everything's great.”

“I liked that I was able to get the appointment in very short notice, and they came and did the work. I didn't have to follow up or anything like that. I can tell a difference after they came. I would highly recommend Air Quality Systems.”

“They did everything that I asked in a timely and professional manner, and they had no reason to come back. They completed their project as planned. Their customer service was excellent.”

“Air Quality Systems was just very easy to work with, and they did a good job. I was able to tell a difference after I used them. I would say they were very good. They're A+.”

“They were on time and very professional, and I was able to tell a difference in air quality after using them. Their customer service was great—A+.”

“They were just very quick and very efficient, and they cleaned up all their messes behind them. A friend of mine who works for an HVAC company recommended them. I would give them an A+ because they were really great.”

“They were very professional, they explained what they were doing, and they did what I thought was a very good job. One person cut his hand kind of badly toward the end of the day, but he went ahead and finished up, and I bandaged it for him. It looked like it was going to need stitches, but he didn't quit. When he talked to his boss, I guess they had come to the conclusion to go ahead and finish up the job. I was really pleased with them, especially since this house is 29 years old, and I never really looked that closely into the ducts. I would just get my flashlight and peep in there, and it looked OK, but when I started taking the vents off, I said, 'Whoa, wait a minute.' Air Quality Systems did a good job; I was pleased with it. I think I could tell a difference afterward—I don't think the house was quite as dusty. Once I got the ducts cleaned, it looked pretty good. I would say it's an A+ for them.”

“They showed up on time, they knew why they were here, and they had the tools and the equipment they needed to do the job. They went about it professionally, and when they finished, they cleaned up. They actually did that twice—I have two houses, and they did it in both houses. I would give them an A+. Truthfully, I can't tell a difference in this house, but this is a brand-new house, and I think our ducts are pretty good anyway. But in the other house, there's absolutely a difference. It's an older house, and the ducts in that house needed cleaning.”

“They were good employees, and they did a good job, I would say. Their work is fine. I would say Air Quality Systems gets an A.”

“They came in and cleaned my ducts. They were very thorough and cleaned up everything as they went through. They had to pull the vent covers off every vent and clean them out, so it was a time-consuming process, but they were very thorough and very tidy with the process. I could tell a difference after I used them. I found out about Air Quality Systems through another company. They deserve an A.”

“They were thorough and honest, and they answered my questions. My wife has allergy problems, and she has noticed the change in the air quality over the last couple of years. I found out about them through another company when I asked for a reference.”

“I can tell a difference in my air quality after using Air Quality Systems. I would rate them as an A.”

“I think they were contacted through my HVAC company. They came and did a pretty good job—they were quick and clean. I know that the air ducts were dirty, and they did clean them up. I would tell anyone who asked that they're worth hiring. They get an A.”

“I liked that they didn't get stuff everywhere. They cleaned up. I was able to tell a little difference. They were OK.”

“Air Quality Systems is nice. They put protective covers on their feet, and they did everything they told me they were going to do. They forgot to put a grate back, so I called them, and they mailed me the screws so I could put it together myself. Other than that, everything was just generic customer service. I'd probably rate them as an A.”

“They were fast and courteous, and they did a good job. They were in and out. They were good and reliable. I would give them an A.”

“They were efficient, and they worked very hard. There was a noticeable difference in air quality. I would recommend Air Quality Systems—they're an A.”

“It was great. They just came prepared—they were on time, they had the right equipment, and they did the work and finished on time. I think I could tell a difference; it's kind of hard to determine that, but I can tell by looking at the ducts. I get fewer allergies in the morning and things like that, so it was worth it. Their customer service was great—they were just good people, and they were easy to talk to and explained what they were doing. They didn't mind me looking over their shoulders. I would give them an A grade.”

“They seemed very professional, and as far as I can tell, the systems were cleaned properly, so I think they did a good job. I remember that they were very courteous—they were some nice guys. Air Quality Systems gets an A.”

“Air Quality Systems was really good. They took pictures because the stuff they got out was awfully yucky. I have asthma, and not only were they thorough, but they were very conscious that I was in the house. They told me the biggest clog was in our bedroom area and was mostly from our cats. That helped me make some changes to make it easier to breathe, and whatever they did helped the airflow. It was definitely a positive experience—A+.”

“They were very prompt and very cordial, they made sure they came in with protected shoes, and they finished very quickly and cleaned up. I was very satisfied. They explained the process and about how long it would take, and I can tell a difference. I'd recommend them, and I would give them an A+.”

“AQS was very clean, and they did a very good job. They cleaned the ducts, and I'd definitely recommend them—they're A+.”

“They repaired a mold issue for us, and they did a fantastic job. We particularly liked the job they did—it was excellent. They get an A. It was excellent work.”

“They cleaned my ducts. My air conditioning company recommended AQS, so I trust them. We're very pleased. Everything was done in a timely manner. They came when they were supposed to come, they were nice to have around, and they were very competent. I would give them an excellent grade.”

“They cleaned all the ductwork at our lake house. My air conditioning people recommended AQS, and they were great. They were very good at what they were doing. They cleaned up behind themselves, they were very courteous, and they did a wonderful job. I'd give them an A+.”

“AQS provided duct cleaning services for me. It was great. They showed up on time and were very professional. They did a good technical job, and they took care of the problem. I chose them because they had the best certifications and the best reputation for being able to handle my client's allergies. They get an A.”

“AQS was efficient, and they cleaned up after themselves. They seemed to do a good job. They did the duct cleaning from the crawl space, and then another gentleman came in, took all the vents off, washed them, and put them all back. They cleaned up any debris or anything that fell off the wall where he was screwing them in or out. They did what they're supposed to do, and I liked them. I was impressed. They were recommended by the company that installed my furnace and air conditioner. They were great—A+.”

“AQS cleaned the entire heating and air system, and they did a good job. I am very pleased. They were really thorough with their cleaning of the system and everything, and the house smells better now since we got all the dust out of it. They were referred to us by a friend. I would rate them as excellent.”

“We've had a very positive experience. I would give AQS an A for excellent.”

“They were good. We had moved into a newer house, and we were getting a new furnace, so we thought we should clean out the ducts in the meantime.”

“AQS did a good job. They cleaned all the vents, and they were very thorough in cleaning everything out. I've had duct cleaning done before, and I'm not sure that the other company was careful about making sure they cleaned all the vents. AQS was extremely careful of that. I have cats in my house, so it's important for me to get every bit of cat fur out and everything like that. They did a good job. They get an A.”

“They did a good job. They were very nice, hardworking people. AQS gets an A—they did excellent work.”

“AQS was phenomenal. We had some issues with our dryer vent, so they came out. They were very professional and very kind, and they thought they had fixed it. It didn't seem like they fixed it, so I called back and actually spoke to the owner of the company, and he was so concerned. He said, 'No, no—this has to be done right.' He came back with his two technicians. It was just that when we ran the dryer after they had cleaned the vent the first time, it dislodged something. It was not their fault at all. But they came back and reran everything to make sure that it was absolutely fine. It was quality service, and the customer service was top-notch. I even wrote the owner a thank you card—it was that good. I would give them an A+.”

“They were extremely thorough and went above and beyond what they really needed to do. One of the things they discovered when they were doing the duct cleaning was that paint had been put up in the area where the ducts start. That was important to us because when we moved in here, we had to have all the old paint stripped off and this milk-based paint put on so that there were no toxins coming off the paint. So, they stripped off all that old paint for us so that we could put the proper paint on there. That was really, really nice of them. It took extra time, but they didn't charge us anything extra. I would say they definitely had good customer service. They were recommended by the people who've been servicing A/C and heating for me and my family for about 30 years. They get an A+.”

“I had AQS clean the vents, and they did fine. They did scratch the floor when they moved a desk, but the manager or supervisor took care of it, so it was fine. My air conditioning company recommended them. I'll give them an A.”

“AQS cleaned the ducts. I'll give them an A.”

“They had to come back twice, but they were excellent. The first time, I don't think they got everything out of the ducts, but as soon as I called, they came right back the next day and got everything out. They came in and cleaned all the ducts and vents in the entire house, including the air conditioning coils on all three units. They did a great job. We just moved into this house in May, and the previous owners had a dog. I couldn't even come in and stand for five minutes, so I was really worried about moving in after that dog. Once I got AQS in here to clean everything out, life has been good. We have no problems with allergies. They did work for me one time before, and I would rate them as an A.”

“AQS did a good job. They just did the dryer vent, but it was a very odd-shaped dryer vent that goes from the middle of the house, kinks around, and turns. It is vented to the exterior back part of the house, so it has lots of bends. They looked inside with the camera and found 24 years of lint—enough that it would have been a fire hazard. They didn't make a mess, and they didn't damage anything in my house. I'd give them an A+. I would call them back without any hesitations.”

“AQS cleaned all the ductwork in the house. They were very professional and very thorough, and they explained everything that they were doing. Our heating and air company recommended them to me. I would give them an A+, no doubt.”

“They cleaned our ducts, and I liked their professionalism and the thoroughness of the job. We found AQS through a referral from the people that handle our air conditioning and heating system. I'd give them an A+.”

“I've used AQS in the past, but most recently, they cleaned all the vents in the home that we just purchased. They do what they say they're going to do when they're scheduled to do it. I initially heard about them through another company that uses them. They're A+.”

“They cleaned my dryer vent. They were honest guys. They came out, cleaned my vent, and told me what I needed to do to keep it maintained until the next visit. The employees who came out to do the work were nice. No complaints. They deserve an A.”

“They were very good. I thought they were very efficient and thorough, and they did a great job. It was just a standard, regular cleaning. We had never had it done since the house was built, and a lot of dust came out. It made a big difference. I got their name from our air conditioning people. I would give AQS an A, and I would definitely recommend them.”

“AQS arrived when they said they would, did the job, and didn't make a mess. They cleaned up. They explained what they would be doing. It was a positive experience. I would give them an A.”

“AQS seemed very professional. They did a great job and explained everything they were doing. I was referred to them by a friend. We had just moved into the house, and it appeared that they had not had the ducts cleaned in the past, so I wanted to have that done. I'd give them an A.”

“Everything was good. I would give AQS an A.”

“I had AQS do duct cleaning. I had a lot of stuff to blow out of the air ducts and all that, and they did a real good job. They helped me a lot. I would give them an A.”

“AQS was very efficient. What I really liked about them is they were here on time. They were here exactly when they said they would be, and they didn't stop until they finished the job. I was totally satisfied with what they did. They did my son's house, too, and he was equally as happy. We had new heat and air put in, and the vents and things had not been cleaned in several years. We wanted all of it done at one time. I'd grade them an A. I would use them in a heartbeat, and when I need the work done again, I will.”

“We had a mold issue, so AQS came in and cleaned up. They were professional, and they did fine work. They were recommended by my heating and air company. I'd give them an A.”

“AQS did a good job. We had done a lot of remodeling, and I felt like we had ducts full of stuff. They came in and cleaned it out, and I can tell the difference in the dust level in my house. I would definitely recommend people do it. They were referred to me by my air conditioning company. AQS gets an A.”

“I have my own heating and air conditioning company, and AQS does duct cleaning for me when I need it done for my customers. They do a good job—there is general satisfaction from everyone who uses them. Their work is an A.”

“We had the work done, and they did a good job. Everything was OK. They get an A.”

“AQS cleaned our air ducts, and they did a good job. There was nothing I disliked about them. It was a good experience.”

“They did a great job. I needed my ducts cleaned, and AQS was recommended to me by a contractor that had worked with them. They showed up when they were supposed to, left the place clean, and charged me what they said they were going to charge. All the way around, I was pleased. I'd give them an A.”

“They answered all my questions, they were very efficient, and they cleaned up very well when they finished. My heating and air company had AQS come out to do the duct cleaning, so that's how I found out about them. The employees who came out were great. I would give them an A. They were really good. I can't complain about anything they did.”

“I had some duct cleaning done last October, and I didn't have any issues with it. They came in and did the job they were supposed to do, and everything is good. My HVAC contractor recommended them. I'd give them an A.”

“They were efficient and did the work, and it didn't take that long. They were fine. It had been a few years, and there had been roaches in my attic. I thought there must be a lot of dust up there, so I just had the ducts cleaned out just in case there was residue from that. They said they got a good bit of dust out. They're an A.”

“I have a 30-year-old house that had not had the vents cleaned, and AQS cleaned them all. They seem to be very attentive. They showed me what they were clearing out, so that gave me peace of mind. They did a good cleanup. They would be an A.”

“AQS was efficient. They cleaned out our air ducts. They came when they said they would be there, they did a good job, and they cleaned up. I would say they're an A.”

“They seemed to know what they were doing. They said what they would do, and they seemed to do it as far as getting the ducts cleaned out like that. The equipment they had looked like it would do what they were saying it would do, so I trusted them. I would recommend them. I chose them because another company recommended them. I'd have to give them an A.”

“They came the day they said they would, and they were organized. I had booked them maybe a month before, and they were on top of it. They went from vent to vent and set up the equipment—they knew what they were doing. They took the vents off the ducts, sucked out the dirt from them, and cleaned them. They found a couple of old pieces of clothing, old pieces of wood, and some other debris in the vents, and they cleaned those out. I think they did all of the vents in the house. They charged me what they said they were going to charge me, so I was pleased. When I called to schedule, the person I talked to sounded like he knew what he was doing and had done it before, so it gave me a lot of confidence. I'd give AQS an A. I didn't have any complaints.”

“AQS came and cleaned the air ducts, and it was great. It helped my husband's allergies, and when I sold the condo two months later, it was a great selling point to say I just had the ducts cleaned. I worked at a heating and air company, and they recommended them. They get an A grade.”

“We had AQS do duct cleaning in January, and we were pleased with them. The technicians were great. They were very careful with what they did in the house—they were very polite and very professional. We would rate them an A.”

“They cleaned our air conditioning ducts. They showed up on time, they were professional, and they did a good job. We saw them in Best Pick Reports. I'd give them an A.”

“We were very happy with AQS. We moved into a new house, and it was quite an old house. The guys were able to clean out all the air vents and take out all the smells of the previous owners. It made the air feel a lot healthier, and it made the house feel a lot cleaner, too. AQS was recommended to me by our good friends that own an HVAC company, so we just automatically went with them because we trusted the gentleman's opinion and knew he wouldn't steer us wrong. I would definitely give them an A.”
