If you have vents in your ceiling for an evaporative airconditioner, take one of the vents out to use as a template, trace around vent on white card and cut out enough squares for your entire house. Be mindful sometimes you may have different size vents in some rooms. Once card is cut put the vent back in ceiling and then push card up so it is flush with ceiling.
Not only does it look neater it also prevents the warmth from your heating going out through the vents.
You will be surprised at how much warmer your house will be on a lower setting but also your heating costs should hopefully reduce.
