A lot of people just crank up the dial when they want more heat, or drop it for a blast of cool air. But this method of heating and cooling wastes energy and money. You’re also less likely to get the temperature you need. Most new homes are digital with touch-screen controls that are easy to read and more responsive than standard thermostats. These digital thermostats allow you to pre-set temperatures for every day of the week to match your schedule. You avoid high-energy temperature swings as you enter and leave the house.
Some digital thermostats also allow you to program the heating or ac 24/7 with pre-programmed timings. This allows additional energy costs while your away on vacation or at work.
