Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Appears some of the newer systems have add-ons that remove and add humidity. We enjoy extremely dry summers and extremely moist winters, and its not unusual for the humidity to drop to 15% or rise to 75-80%. We offset this with a console dehumidifier and a small humidifier, but if I could have the main system keep us at about 40-45% all the time with no monitoring...that'd be nice.
I have good slope on the pan, and the drain works fine...but the pan stays damp, its dark, and its hot...mine is in the attic too where it hits about 130-140 degrees in the summer. We get a nice coating of red mold, and its persistently showing up in the shower tile and anywhere else that gets moist in the house.
New house has the system in the garage, I have a lot of room, water, electricity, air and water venting all very accessible. The ducting has a problem of not actually being connected very well, so i'm already going to have to secure and tape all the ducts in the house, and the attic venting is exposed to some sunlight from the roof air vents and the insulation is starting to decompose from the UV, so it'll need to be replaced or re-wrapped with some uv reflective insulation.
With all this and an old system, I figured it may just be time to have an HVAC expert come in and do it up right.
I'm a bit of a believer in the UV systems. We've got some air purifiers that we've used that come with the UV lights. Their claim was that they'd kill mold spores along with the bacteria, and after a time...about 30 days...they'd kill enough of the mold spores that the dust mites would starve off as well. Mold spores are a primary food source for mites. We put two of them in my wifes older smaller house, and while she noticed an improvement right away in breathability, after 30 days she all of a sudden reported feeling much better. I hadnt even told her about the reputed time delay and 30+ day benefits, so I dont think it was a placebo effect. However the two units we have are just too small to fully control the air quality in the home we're in now, and definitely not in the new house. Looks like about $600-700 to make the furnace into a whole house purifier, and if you stick with the electrostatic jobs and steer away from filters that have to be replaced, the annual cost is under $20.
Since the unit is pretty accessible, changing the UV bulb once a year or so isnt that big of a deal.
