I went to your site and I didn't see anything about air duct cleaning. I would definitely consider investing in a decent air duct cleaning system (not rotobrush) Slow times for carpet cleaning are good times for ADC. $8K to 10K will get you a nice system, you could get one for about half of that if you buy it used. It is by far the most profitable service we offer and I don't even charge top dollar for it. It leads to all kinds of referrals and alot of times we end up doing the carpets, t&g, and upholstery as well.
