There is a tiny house movement that continues to gain momentum all over the country. You would think that tiny houses would not be built in the northern climes, since the need for a furnace or some kind of efficient heating system is an absolute must. Traditionally, tiny houses resemble mobile homes more than anything else, and mobile homes have been notorious for exorbitant heating and cooling costs. Indeed, some mobile homes have not had adequate heating to keep people from freezing to death in the really cold areas of the country. But the tiny house business has improved tremendously, and so has heating and cooling technology. In my state, it is mostly hot; in the northernmost parts of the state, we do need heating during the winter, but nothing like those in the northern states. In the southern part of the state, they really don’t even have a true need for a furnace at all. When I decided to build a tiny house as a rental unit and vacation spot, I had a lot to think about. HVAC was pretty high up there on my list of concerns. I thought about old fashioned window a/c units, but they are so outdated and inefficient. In the end, the HVAC company recommended a mini-split air conditioner, so that is what I had installed. I want it to offer good indoor air quality, strong climate control, and efficiency that results in lower cooling costs. The tiny house is still being built, but soon I will find out if the mini-split a/c meets all my needs, as the heating and cooling company promised me.
