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

Before paying a ton to an HVAC guy just for coming out check all your doors and windows. We had some weather stripping that had been clawed away when we got our dog (puppy at the time). The front door also had a big gap that had probably been there since we bought the house. Eventually enough was enough and our house began having high humidity. We replaced all weather stripping and it went back to normal immediately and stayed that way. Worth a look because it’s a super cheap fix if that’s the issue.

Also, you can get a dehumidifier for $200. Hell it will cost $150 to call an AC guy out. Dehumidifiers are pretty cheap as far as electrical cost goest also.
If your house is cool enough for you but not pulling enough humidity there are other options.

To prevent mold, the EPA recommends temp 75 and below and relative humidity at <60

This is what mine is showing this morning.

I am having this issue as well since the AC guys came and "fixed" my AC 2 weeks ago.
Typically my house is in the mid 50's humidity wise, but since they came it is 65% plus.
The AC issue was some sort of short that caused the AC and heater to run at the same time. Less than 350 for the fix, but may need to get them back out to the house.
I do have a humidifier left over from the 2016 flood that I use regularly, it can usually make a whole day before I need to empty. Lately just a few hours.

Interesting, just watched a HVAC tech YouTube video on most likely causes for AC and Heater running at the same time. LINK
Definitely get the HVAC company to send someone back out to check your system - something is not right, maybe a blower/air flow issue associated with the repair. If it is a larger company with multiple HVAC techs ask them if they can send out one of their more experienced techs to trouble shoot the issue.

If you open your refrigerator and a thunderstorm develops in your kitchen, the humidity is too high in your house.

Supposed issues I have seen ~ blower moving too much air and AC cooling to fast, both preventing proper humidification.

Ask the HVAC tech to check your total static pressure, should be about 0.5 in WC, if it’s to high they’ll likely reduce your air handler blower speed to correct the problem. If you were getting good dehumidification before the repair, it must be something simple like that.

Supposed to be by sometime today.

Tech came yesterday cleaned coils, changed internal filter, checked Freon. I got home from work, temp was 71 humidity was 72%. So I called him back a bit upset, he came back today, blower was running too long, and sucking in air from the attic.
Supposedly fixed now. look forward to not sticking to my sheets tonight.

Well that will do it. Blower running to long or blower speed to fast? By chance did he say where it was sucking in attic air. Seems like the first crew must done something accidentally if you weren’t having this issue before.

I actually spent some time in the attic doing my own troubleshooting, the air was being sucked in around the Freon pipe, drain pipe, and under the compressor. I used a cigarette for a "smoke test" I taped every leak I could get to, but could not get underneath it.
It is back to normal, 48% humidity in the house.
