Our triple-car garage in Ogden, Utah, faces west. Even with ceiling and wall insulation it gets really hot in the summer and really cold in the winter. We'd be happy with around 83 degrees in the summer and 50 degrees in the winter. Would it be more cost-effective to install through-the-wall heating and cooling units or to purchase insulated garage doors?

Bennie, If you want a climate controlled garage then you will need some sort of heating system for the cold winter months, and if you are going to spend the money on heating bills, then it makes sense to have a well-insulated garage. So I would suggest that you need both a heater and insulated garage doors. If your garage does not have insulated doors, then the heat lost during the winter is just going to cost you money. During the summer, you may be able to keep your garage at a reasonable temperature without needing an air conditioner, especially if your garage is well insulated with no windows.
I think the first thing that you should do is make sure that the garage is well insulated and then you can determine what type and size of heating (or cooling) equipment is really necessary. Remember when structures are super-insulated then they require very little energy for heating and cooling, which can help save you a lot of money over the long haul.
