I have been trying real strenuous to save money on energy use. And that starts with the use of our central heating and a/c method unit… Did you suppose that central heating and a/c systems are the number a single cause of super high electric bills? It’s true! I really did not suppose either until recently. This is why our current goal is to use portable heating and a/c unit to help in our job to use our central heating and cooling unit a lot less. Portable space furnaces and portable a/c systems take up much less energy than a central heating and a/c method unit. And they do a great job at heating and cooling whatever rooms they are in. So this is what I did. I went out and purchased both a portable a/c method plus a portable space heater. It is Winter right now so I am using the portable space furnace in conjunction with our central heating and a/c system’s heater. It is laboring out great. In the first month alone I saved almost half off what I correctly have been paying in daily electric bills this time of the year. The way this is laboring out, I can only imagine how fine the portable a/c method will help myself and others once the legitimately hot Summer weeks roll along and arrive. I really spend a lot of money on our electric bills that time of the year usually!
