Best Energy Bill Saving Move?

I suppose that the price of oil seems to be falling a lot with all that is happening in the news, then this is making myself and others try & figure out what type of things would be the smart transfer when it comes to saving money; Energy saving tips are entirely a make & break issue when it comes to energy bills of course, and as oil is going to be cheaper for maybe a long time, should I be looking into getting a new Heating, Ventilation as well as A/C unit? Or should I put the money elsewhere, because Heating, Ventilation as well as A/C repair will be the least of my worries with energy bills being so low? With gas being cheaper, the plan of a new Heating, Ventilation as well as A/C plan that is more fuel efficient hastily seems less important, then i suppose that it is wasteful for the environment to have older systems, however at the end of the day, I have to deal with real world concerns of my own, & I am not sure how the economy is going to be in the near future, then but it entirely does seem enjoy oil will be cheap for a great long while. That much does seem lik as close to a sure thing, so maybe I should focus on the things that I do know, or as close to knowing the future as is possible, on that note I am thinking of getting an updated gas gas furnace, so that I am nice & hot in the Wintertide no matter how it frigid it gets, as after all the energy bills are going to be cheap!
