Spray-foam home — ventilation?
I hope you can help. I’m in a less-than-a-year-old, production-built, spray-foamed, tight, energy-efficient, 2-story home outside Orlando, Florida, 1,758 square feet, which developed “sewer”-type odors on the first floor.
The builders solution so far has been to install an inline “booster” fan to the fresh air intake on the AC system to meet ASHRAE 62.2. But now, understandably here in Florida, indoor humidity has risen dramatically.
Is my correct/best solution to install an ERV? I don’t want to just crank my AC down to remove the humidity, as that defeats the purpose of an energy-wise home. I need the builder to understand what the correct thing to do is.
Thanks for the help.
