Anyone work in the hvac industry? Familiar with Mitsubishi ductless heat pumps?
I have had mold problems for three years with mine. The first one, I was told was over powered for my 500 sq ft house, and therefore never shut down, or completed "cycling." They came out, masked and plasticed the full of mold box off, until they could come and exchange it. They put a smaller unit in with a cold plasma air sanitizer unit and it still molded.
This thing pumps out humidity like you wouldn't believe. For the last year and a half since the new one was installed, I have run a dehumidifier 24/7. I still struggle to keep the humidity under 50%.
I have tried:
Lower the temp and lowering the fan, if I do that, I end up with a temp 10 degrees above the temp requested. I can't seem to lower the fan.
Auto doesn't work either for maintaining temperatures.
I don't use a schedule, because if I let it get warmer, it will take hours to get the temp back down. It's set to hold at 70.
I clean the filter once a week minimum with a vacuum and wash it once a month and let it completely dry before installing. I've also brought in an air compressor and blown the dust off it.
The blower and the wire grating is full of mold. Again.
This is a serious issue, as mold is bad for anyone, but the whole reason this was installed was to help my asthma, and needless to say, having a house full of mold spores isn't helping.
I also have two air purifiers, and the dehumidifier has a filter system as well plus the unit itself has the cold plasma air sanitizer and hepa filters. In 500 sq ft! I can't imagine what else to do.
The contractor has no ideas why this is happening and offers no solutions. I'm still working with Mitsubishi, but all I keep hearing is the implication that I'm doing something wrong, that it is somehow my fault. The contractor tried to imply I was DIRTY, and that it's because I have dogs. Um. My house is super clean, cause uh, hello allergies and asthma? Plus, if this thing can't handle me and two dogs, how is it handling FAMILIES?
Help?
Suggestions?
