Hi, I am having a new AC & furnace installed soon. I have an 1800 sq ft ranch located in Nebraska. The unfinished basement is an additional 1700 sq ft, we plan to finish about 1300 sq ft of that this year.
I've decided I want a whole house dehumidifier, especially after reading many of teddy bear's posts. My house has humidity problem, the basement smells musty sometimes and I find mold grows easily in our house. I'm getting a basic AC unit (single stage, 13 or 14 SEER) and a 95%+ furnace with variable speed fan.
All of the 4 hvac companies I've talked to do not know much about dehumidifiers. They say they can do it but it sounds like they have never done it. What do I need to do to make sure they install it correctly? Should it simply pull from the return somewhere before the blower? And then output into the main duct after the coil? They want to use a Honeywell DR90. Is this an appropriate size unit for my house?
The installed cost is very high, almost double what I can purchase the unit for online. So I'm thinking about installing it myself. Is this possible for someone who is handy? If I went this route I think I would want the Ultra-Aire XT105H but I don't see where I can purchase online. It is much more efficient than the Honeywell. I'm pretty confident I could handle the mechanical install, but I'm unsure how to hook it into the fancy new thermostat that comes with my new system (either a Honeywell IAQ or Trane comfortlink II).
Thanks a lot for your feedback.
