I just had my blower module replaced because my AC coil was frozen over. The underside of my coils had a thick mat of dust because I had never had it cleaned. I cleaned it myself by using a soft brush attachement on a shop vac. The inside of the blower appears to have a white/green growth, and I am sure the ductwork of my 30 year old house can’t be in good condition.
I purchased a Groupon for cleaning of unlimited air ducts and one return vent for $39. I should have checked into their hours first because they only offer services during normal business hours. So, with no evenings or weekends available you have to take time off work. I asked Groupon for a refund when I realized this and they refused because it wasn’t within the three day window. Then they didn’t even show up or call for the appointment. I called them after they were an hour late and they were going to call the local dispatch office and have them call me back within 15 minutes. I did not receive that call. I called again and was told I would get a call back from a manager. That didn’t happen either. So I asked Groupon for a refund again and they gave me Groupon bucks. When the survey came asking if I was satisfied with the Groupon customer service I said no, I want real money. I got my real refund the next day. Seems to me Groupon should stop dealing with these companies.
NADCA and EPA both have good points. Although, organizations are made to make money. Common sense and looking at NADCA and EPA pre-checklist. If you don't see it in the check list, you don't have to do it! But, if you do, look up Diamond certified co.s and the BBB. Beware of bait and switch scams, $60 vents and the like coupons which claim to help all for the measley sum of $79.00 bucks.
Hello, I read your comment and I know it was two years ago but I hope you see my message. I am trying to figure out what to do as I was told that there is some cat odor in the finished basement. I think with the air conditioning running that it may carry odor. The litter boxes are always kept clean. I wonder if odor can be trapped in the ducts, if Air Duct Cleaning could help, but it is quite expensive plus I'm concerned that it may not help. Please elaborate as to why you think it doesn't work that well. Do you have any other advise? Did you work in the field of Air Duct Cleaning? Thanks so much!
Some research suggests that cleaning heating and cooling system components (e.g., cooling coils, fans and heat exchangers) may improve the efficiency of your system, resulting in a longer operating life, as well as some energy and maintenance cost savings. However, little evidence exists that cleaning only the ducts will improve the efficiency of the system.
