What would be an optimal humidity level in my home during the summer? Wouldn't a thermostat with a humidity/dehumidity control on it do the job for a lot less money? I live in central Massachusetts. My house is 2100 sq. ft. and I have a 3.5 ton AC unit/coil on my furnace (with floor registers). Thanks!
What is wrong with this picture? If I put a whole house dehu in your home, I would set the dehumidistat to turn on the dehu at 53%RH and turn off at 47%RH. If your %RH meter is accurate, your home is perfect. During wet cool weather, with 50-75 cfm of fresh air ventilation during occupancy, 50%RH is unlikely. But if you confirm <55%RH with adequate fresh air, document the miracle, relax and enjoy. Regards TB
Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
