House is very cold!
Just a backstory: we have a home that was built in 1900. However, in 1986, we put on an addition.
We have a furnace and AC system that is about 7-8 years old. But, our house just has always seemed cold. I wouldn't necessarily say drafty, but cold. It is a one story, with an attic and a crawl space. There was no insulation in the old part of the attic, and some batting insulation in the new part. We knew there was some batting insulation in the walls of the new part, and assumed the old part to be hollow.
So, we called an insulation company. They came out, went up in the attic to look around, used some fancy contraption to measure heat, and agreed the older part was likely hollow. They quoted us a price, and we hired them.
So, they arrived, and drilled some holes from the outside around the house. Come to find out, there WAS cellulose in the walls on the old part. So, they pulled out the batting in the new part, and injected some spray foam. The did nothing with the old part's outer walls. I really would have preferred to have something done with the old part. But, according to them, there was already insulation in there, so they didn't need to do anything. So, they went up in the attic and did some cellulose blown in over the entire attic. We do not remember ever having insulation put in, and my husband has lived here his whole life, and I have lived here 35 years. So, the insulation that is currently there is very, very old. So, I cannot imagine it is very effective.
They suggested that we may want to think about insulating the foundation. We have thought about it, but for now, we are waiting to see how much of a credit we will get since they did not have to insulate the whole house.
Well, according to the thermostat and an indoor thermometer we have, it is 70 inside our house, with nothing on (45 outside)However, at 70, it is still very cold. we have to layer on sweats, use blankets, etc. It is just very cold. The walls are cool to the touch.
I just don't know what to do at this point?
