Yeah. They didn't warn me they were going to cover them so I had no reason to turn them off until it got so hot I complained and they said to turn them off. I'm kinda freaking out at this point.@ChiefDThe roofing video guy's theory does make some sense. With the vents at the top of the house the hot air build up should lesson in the attic space above.
And really, that's the only thing that has changed, since the roof composition itself sounds like about the same.
If the AC tech found that the system is operating normally than to me that explanation makes sense.
Ok...I'm getting pretty worried. Inside humidity has been 70-75% all day. AC guy only checked the upstairs (split) unit since the humidity was noticed upstairs. Now I'm thinking the main downstairs unit might be the issue.
I have a a cheapo hygrometer but it seems fairly accurate (within a few percent of the fancy one the AC guy had). I put the hygrometer on two of the downstairs registers both show 80%. I'm not sure if that's a good/bad way to check it but seemed worth a shot. What could this be? The downstairs unit is keeping the temp we selected on the thermostat. I know nothing about these things and am about to go into the crawlspace to see if the return duct looks ok (not that I know what to look for).
Any ideas?
FWIW the roofers covered the AC units with plastic tarp and the indoor temp reached 95 before I turned off the AC and got them to uncover the units. I don't know if running the units under those conditions could have damaged them, or if the roofers could have done something (falling debris, accidentally kicked a copper tube, etc.). Roofing company's response was "no roofing components on any roofing system affect indoor humidity".
Were the units running while covered?
Humidity that high is very bad if it stays that way for more than a day or two. If it stays like that for a week you’re going to have mold everywhere.
