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.
