I suppose 1 of the best tips I can supply you for saving energy on your cooling and heating costs is to invest in the most efficient heating and A/C system you can find. Get a reputable contractor to install it and get a great maintenance plan from them and you will be set for years. I love to stick with the top name brands when it comes to heating and A/C components because they just run better and last longer than the cheaper no name brands. The efficiency is simply incredible nowadays with the latest component and our power bills are almost as low as our wireless bill each month. I would prefer to switch to a solar heating and A/C system 1 afternoon once I know that it is advanced enough to beat the electric system that I have in our house now. I guess that they are consistently laboring to improve things in the field and can only imagine what they will be loved in another twenty years or so. I may invest in a geothermal heat pump 1 afternoon when our current heat pump is outdated and ready to be replaced, but I am pretty ecstatic with how much, or how little, our power bills are during the winters. I simply also advise having some type of dehumidifier in the house because lowering the humidity in the summers in the house can make you know much cooler for much less. Installing ceiling fans in each room you frequent is another way to trim back on cooling costs. You could also get zoned heating and cooling akin to what I have to avoid heating or cooling the whole house.
