$2.54 @ Home depot!
Mind you thats for a 5in, you'd need to measure your ducting and buy the appropriate size (normal would be 6in). Installation is dead easy, just need access to a joint or the end of the pipe. As long as you can get into the pipe you just drill a small hole for the bolt part, slip the damper in and tighten the wing nut and you're done. Tons of how to's online.
Adding an inline blower fan (~$150 for a standard 100cfm Broan one) along with wiring that fan in circuit with every fan & vent in house is not really the most cost effective option. Unless that is done @ construction, its damm near impossible to add, and would be pricey even then.
Cheapest would be to ensure all the cold ducting is well insulated an a $3 damper is added on the makeup air.
Even adding an HRV (or inline blower, or a $3 damper) might not solve your issue, remember even if you have the best HRV or an inline fan, any of the ducting running from the outside up to the point of the HRV is still going to be as cold as the outside, so you kinda have the same problem regardless, hence, insulation. |
So upon closer inspection the makeup air duct already has a damper on it (it was hidden in the black insulation), but when I went to adjust it, I noticed that the insulation was pretty wet. I assume it's just residual moisture from over the winter but I hope it isn't indicative of a larger problem. I'm wondering if I should just replace the insulated part running from the outside of my house to the ductwork.
