That’s why the contractor you choose can be as important or even moreso than the brand of furnace.
Do furnaces get less efficient as they age?
Yes, furnaces can become less efficient as they age. Wear and tear, lack of maintenance, and outdated technology can lead to reduced efficiency and higher energy consumption over time. However a well-maintained furnace with regular filter changes, should stay quite efficient for most of its lifespan.
Is it more efficient to turn furnace off at night?
Rather than turning the furnace off entirely at night or when the house is unoccupied for an extended period, it’s usually better to simply lower the thermostat setting by several degrees. However, consider using a programmable thermostat to ensure the house is comfortable when you return or the time you usually wake up.
What is the cheapest temperature to keep your house in winter?
The cheapest temperature to keep your house in winter is the lowest temperature that is still comfortable for occupants. For most people, this is around 20-22 degrees Celsius or 68 to 72 degrees Fahrenheit. Lowering the thermostat further can lead to energy savings but may sacrifice comfort. Wear layers and use blankets to stay comfortable at slightly colder temperatures.
Is it cheaper to keep house at constant temperature?
Keeping the house at a constant temperature can be more cost-effective in some cases, as it prevents the furnace from working hard to raise the temperature during colder periods. However, using a programmable thermostat to lower the temperature when you’re away or sleeping can still provide significant energy savings without compromising comfort.
