I'm a newbie in need of quick help re: duct materials. We are in the process of replacing our boiler with a gas-fired furnace in our 1100 sq. ft. bungalow.
We were hoping that the duct work that was installed for our A/C several years ago (by previous owners) would suffice for the furnace. All of the duct work coming off the air handler is the flexible duct material (flexiduct?). We have one contractor saying that we should really replace it with a rigid trunk and only use the flexiduct to get from the main trunk to the registers, and another contractor who says all houses now use flexiduct and that we needn't worry about the lack of a rigid trunk for a house this size.
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />Contractor 1 wants $2200 to replace all the duct work. Contractor 2 wants $150 per length to replace any compromised flexiduct runs (we think there are 2 that need replacing).
Who is right? It's getting chilly and we're without heat, so we want to move fast but not stupidly.
