Heating/Cooling Duct
The duct/vent in the dining room makes noise when the heat comes on. It started a few weeks ago. We cleaned the vent cover thoroughly and didn't change the filter because it wasn't dirty. (But we have spare.). It may be nothing, but I don't want to take any chances.
I'm available during certain hours, yes. Wednesday morning and later in the afternoon, and Friday morning and up till about 3 p.m.
If interested, please get in touch with me. Thank you!
