From what I've read here, I'm beginning to think that my heat pumps are oversized. I live in Central Florida, so it's pretty hot and quite humid here... especially in the summer.
I've been setting the thermostats back to 85 when I leave for the day and when I'm home I keep them at about 78. The house still feels pretty humid and I have a cheap little indoor/outdoor thermometer thing that also shows indoor humidity. I have no idea how accurate that is, but it showed my humidity at around 60 to even 65 percent. I thought maybe that leaving the units off during the day was allowing the humidity to build up too much, so as an experiment I tried to leave them set to 78 for a couple of days and that helped a bit, but the humidity still stayed between 55 and 60 percent.
I only have a single stage system, but I saw from a post here that I might be able to have someone come in and slow the fan speed down which could help keep humidity levels down.
Does that sound like something I should investigate? This is a new house and the system came with it, so I don't have an HVAC company to ask yet, so I'm hoping you guys might have some good advice.
Also, if I do go ahead and have the fan slowed down, would that affect run times significantly? I'm assuming it would cause the compressor to run longer (and have more of a chance to dehumidify the air), but I'm also concerned that if it runs much longer then it would be more expensive to operate. I want to keep the humidity down for comfort, but I don't want to pay a lot more for that... basically... I want it all
