9. Air conditioning and heating
We've already listed HVAC a couple of times in this list, and for a good cause. It is essential for keeping your home warm during the winter and cool during the summer. Heating, Ventilation, and Air Conditioning (HVAC) is an acronym for heating, ventilation, and air conditioning. If you've spent your whole life in a newer home, you might believe that every home should have it.
It would not be available to older families, believe it or not. Building a new one would cost anywhere from $4,000 to $12,000. And if the house has an air conditioner, a lot can go wrong. Minor repairs can cost as little as $50, but more extensive repairs can cost as much as $1,000. If you want to read more, go to HVAC.com's comprehensive list of potential issues.
