I had been hearing all about using portable heating and air conditioning equipment to help reduce energy use for a while. Central heating and air conditioning systems are the main cause of high energy bills as we all know. But I really did not believe that by using a portable air conditioning system and a portable space heater that you could really save money on energy use. I thought it was all internet hype and false information on energy saving tips websites. Well I decided to give it a try just to prove that it was a bunch of lies. I am happy to report that I was very wrong! They were really right. I have been using a portable air conditioning system now for a few months with the worst heat that has been going on in the area and my energy bill has gone down a lot. So much to where if this keeps up I will actually be able to save money toward going on a vacation! That is how much savings I am getting by using this portable air conditioning system mixed with the regular central air conditioning. What you do is use the portable air conditioning system in the day, and when you go to sleep at night turn on the regular central air conditioning system. This really is working out well. And I have no doubt that when winter comes around again and I use the portable space heater that I bought mixed with the regular central heating system that it will produce the same exact results. I am just kicking myself for not trying this sooner.
