Hello all, I'm new to this forum jazz so here I go.
This message is going to seem long-winded, but I want to provide as much info as possible for a accurate analiysis, pardon me on the spelling errors.
I have a 8 year old stick built ranch home in West Michigan,1200 sq.ft. 8ft. ceiling upstairs, 1200 sq.ft. 9ft. ceiling downstairs in the basement. 2*6 exterer walls with blown in fiberglass insulation and caulked from head to toe,(I know, a tight house). I have duct work for my LP furnace and Air Con. and I also have a 8 inch fresh air inlet tied into my cold air return duct work, (thats code in my area).
My basement was finished, (not the ceiling) untill I suspected I had a mold problem, so I ended up ripping all of my 2*4 insulated basement walls out and guess what I found...you got it..Mold. My poured concrete walls were soaked in certain areas and I traced the water to my sweating baseboard joice ends dripping down to the concrete wall below creating a mold breeding ground. And yes my joice ends were insulated. My contractor and I inspected every inch of the house to see if water came from the roof or attic, outside siding leakage, leaky plumbing or what ever. Nothing.Yep, high levels of humidity was the cause. I cleaned up the mess and bought a dehumidifier and the moisture has stopped for now.
I just want to also mention that my upstairs windows have condensation on them quite a bit, I have strange allergies that I never had before and my 2 kids seem to get sick with colds and fevers allot.
So with all this information I have disclosed for you with my geographical area taking in consideration, Which route should I go,,, HRV or a whole house dehumidifier? From what I have read on the internet it seems that the HRV is my best choice but nobody (HVAC Installers) in my area has a clue about HRV's or has much experience with them. I just spoke with a HVAC Pro on the phone and he stated that a whole house dehumidifier is the way to go, but I'm not sure if he is right. Sure it will dehumidifi, but is it fresh air or the lack there of the real issue?
Any and all info would be great, such as what to get,make and model you prefer and if it has worked for you in such a case like mine.
Thanks for your time.
