Moved into the newly bought house and notice someone had not installed the proper vents on the Air Exchange. I had 2 exhaust vents. Went to the local hardware store and swapped the vent. Great...easy.
Since then my heating bills have sky rocketed. Even after filling in 'gaps' with spray insulation and other DIY jobs. I've come to the conclusion that the air to air system is the problem.
We all know the 'X' pattern of air going trough the machine warming up the cold exterior air before exiting and circulating trough the house. Great... Fresh air! But wait! I'm throwing out heat aren't I??? The system is a few years old yes, but the 'X' pattern is the same as my parents' 2 year old house... WTF.
I've talked about this to my father and he's also noticed that new houses now do not hook-up the intake to the wall vent. They just let the 4" hose hang there. I have to double check if it's the intake or exhaust but this is were I'm not certain what should/could be done. Your feedback is much appreciated.
