With low winter temperatures here in Indianapolis typically averaging in the upper 20s, too much heat in your home might not seem like a problem. However, excess heat can be both a comfort issue as well as a needless expense that shows up on your monthly heating bill.

The United States Department of Energy recommends maintaining a winter indoor temperature range of 68 degrees to 72 degrees. Under typical winter conditions, this provides the most comfortable level for most people, as well as the most efficient furnace operation for lower costs. If you find your home temperatures exceeding this optimum range due to too much heat, here are some possible causes to investigate:

Incorrect thermostat setting.

It may seem obvious, but just to be sure, check your programmable thermostat settings to confirm that they are correct. Perhaps someone inadvertently entered a temperature setting that is higher than normal.

Thermostat malfunction.

If the furnace seems to be running nonstop, the thermostat may not be sending the automatic signal to turn it off when too much heat is present. Usually, you can turn the furnace off at the main system’s on/off switch on the thermostat. Then, contact a professional HVAC service to diagnose and resolve the problem.

Obstructed return vent.

If too much heat seems to be occurring in one specific room, make sure the room’s return air vent is not blocked by some object, such as furniture or curtains. An obstructed return cannot remove warm air, thus causing the room to chronically overheat.

Airflow imbalance.

Airflow from the furnace into each individual room is balanced to provide enough warmth to maintain the thermostat setting. Too much heat due to excess airflow into a specific room, however, can cause discomfort for occupants. Airflow imbalance may be caused by closed or obstructed supply air vents in adjacent rooms, a furnace blower that is not properly sized for the system, or internal duct dampers that are out of adjustment.
