Air inside house is supposedly 77% humidity... is that extremely terrible?

I feel like it usually stays around 50-60% for us but I guess all the rain lately has kicked it up. Should I get a dehumidifier?

Seems really high. Not an HVAC guy though.

What kind of A/C do you have? Single,2 stage, or variable?

Is that from an Ecobee thermostat?
77% is high, but I know ecobees are not all that accurate.

Should be between 35 and 45% IIRC
Posted on 8/16/19 at 7:09 pm to thatoneguy
Mine stays at about 50%.

If it’s truly that high something is likely wrong with your HVAC - air flow issue, low refrigerant, clogged primary drain pan, etc. When’s the last time you changed your HVAC filter - is it dirty/clogged? You need to re-check the RH with another humidity meter, but if it’s truly 77% you’ll obviously feel/notice that.
A properly sized and operating HVAC should be keeping RH in the 45-55% range in BR this time of the year.

50% is considered ideal. If you have a smart thermostat make sure you cover up the hole in the drywall with plumbers putty. The thermostat needs to be insulated to accurately read humidity.

Is your AC unit too big for the house?

I live in an old house with several soft spots per weatherization. And I still stay within the 50-60 range at this time of year.
You have an issue. A dehumidifier might help but you need to track the base issue.

Nest thermostat over here.

Cool... imma schedule a visit from a HVAC company soon. Definitely wouldn’t hurt. Thanks everyone!

My nest reads 73% humidity

It’s horrible. Mold city. 60% max. I keep mine at 40-45. Make sure they didn’t oversized your hvac. #1 problem with high humidity levels as unit doesn’t cycle properly. Depending on square footage go get couple dehumidifiers. You need to call an hvac company and have them take a look.

Ours was really bad a few weeks ago and then we realized it was because the fan was set to “on”.
Posted on 8/17/19 at 9:10 am to thatoneguy
How many AC threads are you going to start?
Posted on 8/17/19 at 9:14 am to thatoneguy
I have a dehumidifier in my basement and I like to keep it under 65% or it begins to smell musty. I’ve never seen a reading that high

How often is it running? If you're unit is not running often enough or long enough it may not drop out enough moisture.

I accidentally did that a while back. I guess it just blows all the condensate off the coils back into the air, but you would think at some point it would dry out.

That’s part of the reason but you’re also continually pulling humid air from outside into the house when the AC fan is in the “on” position setting, at least in in S LA. Ones house is not a sealed box and fiberglass insulation in the walls and attic are only thermal barriers, not air and moisture barriers.
