1980 – 1999
This era of houses was built by the lowest bidder (no offense please) but when houses were manufactured with 1-5 models for a subdivision they made the same mistakes in every house. Also, houses were being built a lot bigger to accommodate for bigger families. It is time to consider how many AC cooling units you have or how many furnaces you have and at what capacity they cool and heat the home. Proper insulation and a cooling or heating subsidies like a whole house fan or a gas insert will greatly reduce higher energy bills and lower energy waste.
