LOL! My attic beams were trees, with one side flattened for the roof. Bark was still on the rest of it. No plywood, just rough sawn southern pine for under the siding. Old homes are pretty awesome construction wise.
The columns in my barn are cedar tree trunks with the bark still on them. The some floor boards are easily 24” wide 2” thick lumber. Old house and barn construction was amazing.

Been happening since the day I moved in 5 years ago. My house was built in the 40's or 50's.
I have a client friend who does most of my HVAC work and one of the things he suggested for me a while back was using those cheap blue filters during the summer months. He said the 3M filtrete style restrict too much air flow. Most of the reason I asked was because Ive experienced performance declines from both heat and ac when I neglected filter changes in the past.

Yeah my Dad said the same thing, the fancy filters restrict to much air... 3M makes there filter from 100-1500 and I get the medium level ones. Maybe I should bump it down in the summer to a level?

Jesus. That is not normal at all. Mine run for 30 minutes on and 30 off depending on the setting and depending on how hot it is outside. I live just outside of Toronto. I get cheap filters and change monthly or every 2 months. Increase that airflow boys.

My basement has bad insulation.

Yeah basement and attic... What do you insulate?? The basement with no grow lights on it the winter (10 degrees) would be 58 degrees and in the summer (85 degrees) the basement would be 75+ degrees.
I'd insulate the attic over the basement. When the sun hits your roof, it causes tremendous heat.

They typically size a homes AC unit so that on the hotter days it has to run most of the time. This helps pull humidity down and it makes the unit more efficient than one that turns on and off.

I never knew Colman made ac units till I bought my current place, Colman coolermaster, it’s a relic and runs all the time on hot days, thing runs peak but I assume it’s working hard nowadays. I cleaned my evaporator and condensers really good too, I would make sure those are clean for peak heat transfer.

Renfro you damn know it all!!! Yeah I think I have the smallest central air unit they make bc my house is 800 sq feet. I'm thinking its only like or equal to about 1500 watt's is this correct??? It won't fuck it up running it for say 2 hours on, 10 mins off on hot days??

Mine runs all the time on hot days too and at most weather above 85 degrees. The other day it was 93 degrees out and the thermostat didn't get below 76 degrees. God damn hot basement so the air rises.

Mine would be the same, hot days I can’t get it to the setpoint till sundown, there’s some nights it finally shuts off at 2-3am, I just pretend it’s all good hahaha. House is about 1600sq ft. I made a offer on this place 6 years ago and told them they had to knock off the price of a new ac unit, prob spent it on weed and pizza, still running the Colman cooler master. :grin: I had a 1920s house, mud stick insulation, paper, 700sq ft, ac ran all the time there too. This place is like 1986 with half the argon windows leaking ffs. The grow room is getting new ac before the house anyways, priority’s man.

Insulate the attic roof or floors?.. Yeah my attic in the hot summer is prob 120 degrees
Both, if you can, but the floor of the attic is what tends to get insulated during construction, so that's where it's probably most effective.
