One thing I have managed to find out about having your home’s heating and AC toil best is to use fewer HVAC vents! For instance, if you are not using the air vents in your living room while in the day, then you should close those HVAC vents and only have the 2 in the residing room going, but using only 2 air vents will make that air flow from the central heating and AC device go absolutely quick and absolutely well… The same as if you are not in the living room, close off the air vent.
What happens is the air will easily flow directly out of the 2 air vents that will be in the residing room and it will end up heating or cooling more than just the one area. It will easily spread itself out to almost everywhere on the ground floor near the residing room as well. This was a tip that my local heating and air conditioning device specialist told me to try! And trust me, it works well. It also helps save a little bit of energy use because your central heating and AC does not have to toil as hard to reach the desired temperature set on the control device. Which in turn will also save you a little bit of cash on your monthly energy costs. I have already seen a small decrease in my monthly energy bill ever since I have started to do this with the HVAC vents in my household. My central heating and AC device also works smoother too because of having to toil considerably less.
