I live in a hot desert climate. My Trane roof heat pump is probably 30+ years old. My small house I bought has an AC vent in both bathrooms. One is normal size (not huge), and the other you have to get in and sit on the toilet before you can fit to close the door. The tiny bathroom has a diffuser type register that you can't close, with an old Broan exhaust fan 1 foot away from the AC register. Seems asinine as it will be stupidly be exhausting cooled air (along with any moisture) .
The other register vent in the other bathroom has cantilevers, but even when closed, leaks quite a bit of air. I bought two Delta exhaust fans from Costco I want to install. I want to plug both AC vents in both bathrooms. Each bathroom has one outside wall, but I never notice either bathroom getting too warm. I've read tips about using either plastic or cardboard to cover the vent, but fear when switching to heat mode in the winter, the prolonged blowing of heat on those materials could possibly start a fire. (If you know of any proof that say otherwise, please link to them-- I don't want to risk burning my house down, or run into trouble with a home inspection if I ever sell, although those materials could be easily removed.) I also read of sealing them with metal duct tape. I know that won't burn, but could be a real pain to peel off if I ever had to.
Do they make blank cover plates to take the place of the register? Although if they did, the tricky one would be finding one to replace the diffuser since there's no screw holes, it just snaps in.
My reasons for this question are I feel I need exhaust fans more than AC in the bathrooms, and also air flow is piss poor out of the living room and bedroom vents where we really need it. (as well, as I said it seems asinine to be exhausting cooled air) Can't afford a new unit yet.
