Installing my own duct work for central A/C

[Buckshot]

Apologies is this has been discussed before - I couldn't find a search tool for the forum.

I'm wondering if I could conceivably install my own duct work to save some ca$h. I realize there needs to be a lot of care taken with the sizes of ducts so the air is distributed properly, etc. But, if I knew what size ducts to use and when to slim down closer the end of each line, would I be saving any money? I have a ranch-style home with lots of space in the attic.

It seems that the quotes I've been receiving to have a full system installed are nearly double what they'd be if I already had the ducts in place.

Thanks.

To be honest to you it would be so well worth it if you woas to hire a tech to install your duct, trust me, if you can afford to pay for it then please do yourself a favor and make the call.
But to answer your question yes you could install your on duct if you know how to do it or have done it before.

Sometimes contractors will cut you a break for a little "sweat equity". It all takes time & as we all know, time is money. If you sign a contract to buy the equipment from them, & have them do the final installation, some contractors will give you a duct design for you to follow. You will likely have to check around for someone willing to work with you.
