Just like with food, when something is home made it is usually better than stuff that has been processed in a factory.
However, when it comes to heating and air conditioning, home made can be good or bad.
But when we are dealing with heating, home made heating is not only cost saving, it also can be better in general. A fireplace for instance is a good example of home made heating for your home. When you have an authentic fireplace that is considered home made. You are not using any gas or electric to run the fireplace. It is just natural fire, natural wood and everything is what mother nature made. Cutting wood for a fireplace can eventually end up being a task. Especially if you live in a colder area of the country. Or if you are one of these people who tend to get forgetful to do things. Also if you have issues with your health or are just out of shape in general, having a fireplace may not be the best option. All of the physical labor you will have to go through to be able to have a fireplace can be tiring. I know I had a fireplace in the old house I used to live in many many years ago. And the whole thing that I hated the most was cutting the wood to place in the fireplace. All together though, i personally chose to go with a central heating and air conditioning system for all of my heating and air conditioning needs.
