I don’t know how long it has been the law that you must have HVAC when you build a home, but I have come to learn that all the codes in the cities of our state require Heating and Cooling when you build a house.
In other words, it is not legal to build a house without some sort of heater and air conditioner.
You can go really old school and have a simple furnace and window air conditioners if you like, but you have to have something. It wasn’t until a few years ago that I discovered that having HVAC is a requirement for houses, but there is no such requirement for nursing homes. Well, I’ll take that back. They have always been required to have Heating and Cooling; they were exempt from having a backup HVAC system. All hospitals must have regular Heating and Cooling plus a backup heating and cooling system in the event that their main system is damaged in a storm or whatever. Of course, that was no help when Hurricane Katrina hit, but admittedly Hurricane Katrina force storms are not all that common.In any event all this time nursing homes have not been required to have dual HVAC systems. And yet, hospitals have been having the two systems for decades now. And rightly so. It was not until we had a terrible storm and several elderly people died because the place had inadequate air conditioning. When the storm came, the air conditioning system died, and there was no backup. The people had to live without cooling for weeks, and a lot of elderly people simply cannot handle living in this state with this beastly heat without having access to good air conditioning. In this past Year’s legislative session, they finally passed the laws egging that all nursing homes and similar structures must have both a regular HVAC system and a backup heating and cooling system
