In this economical market everyone is trying to save money every way possible.  I find that many home owners try to maneuver their thermostat with double digit movements.

I recently met a couple that hired me to inspect their new home in Wilmette, Illinois.  The home boasted 3 floors with two split heating and cooling systems.  A split system is a heating and cooling system with an exterior cooling system.  This is standard in newer homes.  Generally, the compressor is the part of a cooling system that is on the outside of the home and the “a-coil” is the portion above the furnace in a plenum. To heat and cool a home of the size I was inspecting in Wilmette, you would most definitely need two heating systems and two cooling systems.

I overheard my clients from the Wilmette home inspection explaining to each other how they were going to keep the thermostat very low when they were not home and turn it up when they came home.  I explained to them that their gas and electric bills would be 50% higher due to this vast movement in temperature.

You can adjust your thermostat up to 5 degrees and not see much of a change in your utility bills.  When you increase these temperature spreads the furnace or air conditioner must run longer to catch up to the new desired temperature.  Example- If you keep your thermostat at 70 degrees during the day when you are home and at night when you are sleeping you set the thermostat to 60 degrees your heating/cooling system will need to run for at least 1-2 hours to catch up.  If this is done daily the costs can be compounded.

My clients from the Wilmette home inspection thought the complete opposite, as do most people.  I also advised having your heating /cooling system evaluated by a heating contractor annually.  This generally costs $99.00 depending on where you live.  You can see other repair prices at home inspection repair prices.

As you now can see, maneuvering your thermostat takes some finesse when trying to save some money on your utility bills.  Keep your thermostat movement to no more than 5 degrees and you will save money in the big picture.  If you have further questions, contact me at Wilmette home inspector.
