School me on whole-house dehumidification … the good, the bad and the ugly?
Looking for some input on whole house dehumidifiers. We are going to be building a 2 story 3,000 sq ft house, the attic space will be conditioned and we’ll be running two HVAC units. Ideally when we are done, we can be at around 900 sq ft per ton on the HVAC equipment. We are in Pensacola, FL which is technically Zone 2. Having lived in South Florida for 20 years which is Zone 1, our area feels pretty much the same. We have extreme levels of humidity.
We hope to build a fairly tight house. On to dehumidifiers. What, if any are the downsides to whole house dehumidifiers? I would “infer” mind you that in theory we may be able to raise the thermostat on the AC up to say 78 vs 72 and with the “drier air”, feel just as if not more comfortable by using a whole house dehumidifier. Ultimately, the HVAC would possibly run less thereby reducing energy consumption. The unknown to me at this point, is what the energy consumption levels are of the dehumidifiers? One model I looked at was the Ultra Air XT155H. As a side note, is adding the fresh air intake a wise option? On the same note as the HVAC equipment since we have TWO HVAC units, would we need TWO whole house dehumidifier systems? As in one for each floor?
As long as we can keep the dew point low and I am sure these units would do that, our comfort level would be greatly increase. Thus, this begs the question “at what cost ?” I know the upsides of these systems after watching several You Tube vids witih Matt Rissinger. However, what goes up, must come down and that’s the unknown for me at this point.
With that in mind, impart your wisdom on me if you’d be so kind and “school me on whole house dehumidifiers”….
