MTE EnergyPros answer members’ most-asked questions
If frigid temperatures have you worried about high electric use and, consequently, a high electric bill, you’re not alone. Calls to MTE’s energy service coordinators spike around this time of year as members seek advice. We asked them to share their responses to the most common questions regarding ways to remain comfortable while saving money on electric bills.
What uses the most electricity during the winter?
David Willhite: Heating your home accounts for more than 50% of your electric bill.
What’s an easy way to improve the efficiency of my HVAC system?
Phillip Price: Ensure that all supply registers are open and delivering air to all rooms in the home. Avoid
closing, blocking or covering any floor vent.
Should I close doors and vents in rooms I don’t use?
Katie McKee: Even if the room isn’t in use, it’s more efficient to have the home evenly heated than to create cold pockets. Redirecting airflow from one room to another should be done at the base of the ductwork with a damper, rather than at the end of the duct line with a supply vent cover.
Should I run my HVAC system’s fan in ‘Auto’ or ‘On’ mode?
Phillip Price: The most energy-efficient option is “Auto” mode.
What temperature should I set my upstairs thermostat at, compared to my downstairs thermostat?
Mark Kendrick: Setting the upstairs thermostat 2 to 4 degrees cooler is a good rule of thumb since hot air rises. Never turn the upstairs unit off because it will make the downstairs unit work harder. It was not sized to heat the entire home.
Beyond sealing cracks and gaps, what’s another way to save money on my winter bill?
Katie McKee: Install a smart thermostat to automatically adjust home temperatures. Set it to automatically lower by 2 to 3 degrees when you are sleeping or at work. Lowering your thermostat saves about 3% per degree on your electric bill.
Should I insulate my garage doors?
Mark Kendrick: Insulating garage doors helps to maintain a consistent temperature inside your garage when temperatures go below freezing. This could help the water heater, if located in the garage, from having to turn on and off so much.
Does MTE offer any programs to help me conserve electricity?
David Willhite: Yes, we have many. To have an MTE EnergyPro assess your energy use and identify the programs and/or simple DIY projects to reduce your consumption, schedule a free Home Energy Checkup at mte.com/HomeEnergyCheckups.
