“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.”
