It is generally not bad for your HVAC system, but turning it completely off and on daily is usually inefficient. Instead of powering the system off, the most cost-effective and system-friendly strategy is to leave it running but adjust the temperature by 7∘F 7∘F to 10∘F 10∘F when you leave for the day.
Manual control can also accelerate wear and tear on your heating system, potentially causing more frequent breakdowns and repair costs. The best approach to save energy and ensure your heating system's longevity is to set a comfortable temperature on a programmable or smart thermostat and leave it alone.
Typically, a furnace should cycle 3 to 8 times per hour, running for about 10 to 15 minutes each time. If it's cycling more frequently (short cycling) or running for 20+ minutes straight regularly, something's not right.
In general, industry experts say you can set your thermostat between 50 and 65 degrees when you're away in winter. But don't go lower than 50 degrees Fahrenheit, or you run the risk of pipes freezing in extreme cold.
The cheapest temperature to keep your house in winter is 68°F (20∘C20 raised to the composed with power C𝟐𝟎∘𝐂) while you are home, and lowering it to 61°F–65°F when you are away or sleeping, according to the Department of Energy. Setting your thermostat back 7°–10°F for 8 hours can save up to 10% a year on heating costs.
No, 72°F is generally considered the ideal, standard room temperature for most homes. However, how it feels depends on the season and personal preference:
Luckily, there are several ways to conserve energy when the temperature drops, including the 15 suggestions below.
No, 68°F is not generally considered cold for a house in winter. In fact, experts at the U.S. Department of Energy recommend 68°F as the ideal, energy-efficient temperature for the winter months while you are awake.
While it may be tempting to save a few bucks on your heating bill at times, a cold snap is not the time to set back the thermostat if you have pipes that are at risk of freezing. Leave the heat on if you plan to be away during cold weather. Set the thermostat to a temperature no lower than 55° F.
Lowering a thermostat by one degree can save you money on your heating or cooling bills. The exact savings depend on factors like climate, insulation, and the efficiency of your HVAC system, but it's estimated to reduce energy costs by around 1-3% per degree for each 8-hour period.
Most homes begin losing heat within a few hours, and depending on outside temperatures, can drop to unsafe levels within 12 to 24 hours. Several factors determine how quickly your home becomes cold, including its insulation, overall size, window quality, and the severity of the outside weather.
It takes time for your home to warm up and cool down. If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it.
For most customers, we recommend turning on your furnace when the weather is consistently below 18° Celsius, which usually happens to be around the end of September, or early October. Some homeowners try to put off turning on their furnace as long as they can to save money, which is okay if you're healthy adults.
While you can actually save about 1% on your energy bill per degree you turn your thermostat down, you should avoid turning your heater completely off. Keeping your home slightly warmed will help keep your pipes from freezing.
How can you tell if a thermostat is bad?
The ideal winter thermostat setting for a house at night is between 𝟔𝟎∘𝐅 and 𝟔𝟕∘𝐅. The U.S. Department of Energy (DOE) recommends dropping your thermostat by 10∘F to 15∘F for 8 hours while sleeping, which can significantly lower heating costs.
While we know that water freezes at 32 degrees Fahrenheit, keep in mind that indoor pipes are somewhat protected from the extreme outdoor weather. Without a heat source, pipes may take as little as 3 hours to freeze at 20 degrees Fahrenheit or lower.
When a cold snap hovers around or below 32 degrees Fahrenheit for a couple days in a row it's time to let at least one faucet drip. Pay close attention to water pipes that are in attics, garages, basements or crawl spaces because temperatures in these unheated interior spaces usually mimic outdoor temperatures.
It is OK to set your thermostat to 74°F if you're happy with that temperature. However, many people find temperatures between 68°F–72°F more comfortable for everyday living. If efficiency is a concern, you might want to consider lowering the temperature by a few degrees to save energy.
Regardless of how long you will be traveling and away from home, keep your thermostat set at 68 degrees Fahrenheit or above. This will help to keep the pipes on the inside of the home from freezing and the ones under the home at a slightly higher temperature as well.
If you're cold even though your thermostat indicates you shouldn't be, your furnace likely isn't the problem. In most cases, it's working just fine. It's your home that needs attention. Lack of insulation, severe air leakage, and/or unbalanced ductwork are frequently to blame.
Never set your thermostat below 55°F (𝟏𝟑°𝑪) in winter. Anything lower puts your plumbing at risk of freezing and bursting. For health and daily comfort, the World Health Organization recommends maintaining a minimum indoor temperature of 64°F (𝟏𝟖°𝑪) to 68°F (𝟐𝟎°𝑪).

This includes both forced-air systems, heat pumps, furnaces, baseboards, window A/C units, and fans. Because they run for long periods and often at high wattage, they dominate the consumption profile.
To save money, aim to have your temperature set around 68-72 degrees Fahrenheit when you're at home and awake. This is a comfortable temperature for most with the help of a light sweater. Overnight and when you're out, around 64 degrees Fahrenheit will keep your home at a good temperature.
