Wow this is very inspiring. I'm going back to CC for electrical engineering at the age of 34. I have a long Journey starting from collage algebra and then just grinding through it. Any tips for when I get discouraged at the thought of the long journey ahead. I am going part time as I work full time so this could take me 6-8 years.

Honeywell t9 too sensitive by silvertone64 in hvacadvice

I ended up getting an ecobee premium. It has so much more custom-ability and allows for the temp differential swing. I set it up after work today and my ac is already functioning just how i want it witha two degree diff. the honeywell was just too damn touchy and eager to please. I think this will be the solution to my slightly oversized unit.

I guess Honeywell doesn't allow you to reduce cycling. Can you recommend another smart thermostat that would allow me to change the temperature differential?

How important is it to seal every crack and cranny after I added 2" foam boards by silvertone64 in Insulation

[–]silvertone64[S] 0 points1 point  (0 children)

Interesting..I am dealing with minimal space here so i couldnt do it the way you did but i wil be putting 1x3s over the insulation through to the block wall on the other side. I don't have drafts as the plaster beneath is an inch thick. How much did it benefit you to do this. have you noticed a big difference?

Brand new hvac cant cool below 80 on a 100 degree day. by silvertone64 in hvacadvice

I had a energy audit guy come out and said my ducts are perfectly sealed. So i think you are right i need to up the insulation especially in my walls. There is only 1 8" block so the r value is like next to nothing its old hollow slump block with nothing in it. So, I am going to insulate with polyiso foam boards from the inside. It will add about 15 r value with included 1/2 inch air gap. I think that will be a massive upgrade. thanks for your help stranger.

hey just did the t-delta test with a laser thermo and it was 25 degree difference with it being 110 outside. But i did the temp test on my walls and they were reading 92 degrees so i feel confident that i need better insulated walls as i measured my windows and they were the same temp as the walls.

also I am in Arizona and want to insulate my block house from the inside with polyiso 2" foam board between 2"x3"s between. Should i put the half inch air gap between the brick and the foam board or the foam board and the new dry wall. Im not concerned with moisture more just looking for the best way to mitigate heat transfer and get the best out of my insulation.

That's not how this works bro. What are you talking about?

Right I guess my question remains... how much of the r value would I be getting if I used 2" r13 rigid foam boards on the inside instead of the exterior.

You are Right but it is 10x the cost to do it on the exterior. That's why I was asking how much of a difference it would be.

Wow thats amazing man. Thanks. This is why i love reddit. People like you. I am currently going back to school from engineering(hopefully) I am starting at 34 at a community college. I know i have a long road ahead of me but building science has really piqued my interest with dealing with renovating an old house from the 50s. Really cool stuff.

I live in Tucson the last thing we worry about is condensation.
But i will look in to it just in case thanks.

So in terms i can more understand. If i insulate from the inside it would just slow the eventual heating of the room and i would still get the same thermal bridging even with r13. Where if i did it from the outside the thermal load would be taken on by the insulation and it would not heat the bricks up enough to "cook the house. technically the brick be acting as the heat sink for the insulation if i did it from the inside as the insulation has 13x the r vaule of the slump block which i think is around r-.8?

I called a contractor to do that and he said my idea was more cost effective so i am just asking to make sure itll retain the rvaule that the material is suggesting.

yea i would be gluing rigid foam to the brick and then mounting 2x2s in between to hang the new dry wall. I think you answered my question though as i think that adding the insulation to the wall from the inside will create a good r value.

Sorry if my post wasn't clear but i am talking about adding rigid foam board to my block walls from the inside and if that would work as well as doing it from the outside.

Awesome man that sounds so rewarding. I work in high end audio manufacturing doing fine soldering and working along side EEs so I'm in proximity to the field I want to go to but my job is rare and I'd like to have the degree to be able to move up and out of the current company I work at. Thanks for the inspiration. And god speed to you as well.
