We bought a house 1 year ago started replaced each exterior door one by one since they were all beat up and had zero spray foam and let in a big chunk of air during the winter so I’m sure it lets out a ton of the cold air in the summer.
We saw a big difference after we did 3 doors but it was during the winter our bill was 150 to 98 bucks for 3 months.
We wanted to replaced the last door and actually demo it and make it a sliding door so we called out a company and they are doing the sliding door and gave us a (to us) great deal on windows (one sliding door custom made with the demo of a single door and 7 windows for only 22,500 with full life time warranty and it’s transferable)
Everyone I’ve asked (husband and other family members) say it will definitely help with our electric bill especially during the summer when we were seeing 250-300 dollar bills.
Have anyone actually done the whole house and saw a drop in your bills? Also side question did we actually get a great deal for the windows two are side sliding windows which we were told cost more.
