think I average 60%. I keep it at 75 during the day and 72 at night.

I'm pretty sure my HVAC is too big though. 4 ton for an 1850 sqft home. I'll have to look into the blower fan speed.



it sure looks like it. Measure your duty cycle during peak heat times (3-5pm). That will tell you how much of that 4ton you really need.

is this the thread where we brag about 45% humidity year round and a $100/mo electric bill?


AKA bragging about having properly sized and configured systems!

Ok so I looked up “whole home dehumidifier”. Y’all talking about these floor units that cost ~$300 or these industrial looking things that are ~$1500? I got issues with this obviously. I don’t know what kinda % but my AC vents in the living room drip water

That could be your duct work causing that if it’s dripping from registers. We are talking about the $1500+ ones that get built into your unit.

Here’s an article that might help you troubleshoot your sweating AC vent - it’s related humidity but I don’t think a dehumidifier is your solution to the problem Why do AC Vents Sweat

Order one or more of these to measure humidity in your house - they are accurate.

That is more likely outside air getting into your ductwork. That would be something that is highly suggested to fix ASAP. You are getting condensation where you shouldn't and that almost always creates mold in a home.

It’s not terrible and it’s only a drip about once every ten minutes or so. And it’s only in the living room where the ceilings are 12’. But I’m looking into it

I have a house built in 1926, 2300 SF…recently insulated the walls on the first and second floor. Still had to add a dehumidifier on the second floor because it was very muggy, but since we did it has been a great improvement. I got a simply floor model with an automatic pump so I don’t have to keep dumping water out of the tray. It keeps the humidity at 50-55%

It should be an easy fix. Probably need some tape somewhere on the ductwork and maybe some adjusting or adding of insulation on that run.

I've been checking since I saw this thread, and it seems to hover in the low 60's.

I have a single 5 ton covering 2700 sq feet (house was built in 1959).

Measure your duty cycles in high heat.

The most common reasons I see this is either a dirty evaporator coil so the coil is not able to remove the moisture from the air properly or a metal grate next to a doorway or other high humidity area that gets cold with hot warm air. The air in the line does it also. But those are all 3 fairly easy checks.
