I'm thinking of doing air ducts

I will suggest you to consult some professionals to get your air duct cleaning done 

This duct fix is a nice one addition to this forum site. Above tips and tricks to manage the duct and ventilation processes are very amazing.

The company I used to work with before spent a lot on I used to spend a lot on cleaning and then we hired in one of those companies which saved us a fortune- would definitely recommend!

This is hard work especially if the furnace is in the attic. You need to spend some time up there if not stick to single story and how do you market that. You really need to know what the hell you are doing. How many people know how to access and or can clean the blower area ?

If one doesn't understand how a duct system runs or installed, or what all is in a system, how can one do it properly. Takes me on the most part 20 minutes to study the system to get my plan of attact together. Show my guys the ruins that come of what trunks, and where in the house all the round pipe runs are connected so they don't hit a screw and think they are all the way there. There is alot more than just sticking a airhose down a vent. If not useing a dedicated duct cleaning system you are best to hire a company that specializes in duct cleaning and add markup to it on your bill. I do it for alot of contractors and I never talk money with the home owner. I do my job and bill contractor and after I leave he bills costomer. Would do same if it were carpet cleaner. Ussually give contractors a little bit of a reduced rate. Like 50 bucks cheaper and I tell them that. Hope this helps a bit. Good luck.

I agree.  I use the spin vax air duct cleaning system and my customers are very satisfied.  Don't forget to change the filters.
