Is It Bad To Run My Heating System 24/7?

The longer you keep your furnace on, the more fuel it will use. If your duct system and home have weak insulation, the furnace will have to use more energy to maintain the indoor temperature. The greater the heat loss, the more energy is expended, resulting in a higher energy bill. If you use the furnace system excessively, you might need to call for an early heating replacement service in Pasadena

Disadvantages of Keeping Your Heating System On 24/7!

Continuously running your furnace system can damage the internal components. Here are a set of disadvantages that you can get by keeping the furnace running continuously:

  • Life Expectancy is Shortened.

The average lifespan of a modern furnace is between 10 and 12 years. The frequency of professional maintenance and the time you use your furnace will determine the replacement time. When the furnace runs 24/7, it puts far more strain on the heat exchanger than you might expect. By doing this, you can shorten the lifespan of your furnace by speeding up its wear and tear.

  • Wasted Energy

There is a common misconception that running a furnace all day will use less energy because it will not need as much power to heat an already warm room. Your furnace will consume energy if the thermostat’s temperature is set at an extreme value. Moreover, the furnace will work harder to reach the desired temperature, but it won’t achieve it if there is leakage in the residence.

Moreover, continuous running can cause the system to break down in the middle of the night. You need to call 24-hour furnace repair company near me to ensure you do not sleep shivering in the cold.

  • Faster Air Filter Clogs

When your furnace warms your home, cold air is pulled in from within, and the furnace system replaces the cold air by blowing warm air indoors. As a result of this process, the constant airflow passes through your furnace’s filter.

You should change your air filters at least once a month if you use your furnace regularly. Air filters on your furnace are prone to getting clogged more quickly than usual as they are used constantly, resulting in lower indoor air quality and more stress on your furnace, leading to more problems.

  • Risk of Furnace Failure

It’s also possible for your furnace to fail if you run it continuously. It is because running your furnace all day can lead to heat exchanger damage. If the heat exchanger develops holes, you might consider heating replacement service in Pasadena because repairing a heat exchanger is expensive. It does not seem cost-efficient to spend tons of money on repairs if your furnace is more than 8-10 years old.


Experts recommend switching off the furnace system for at least an hour or two to ensure your furnace functions smoothly during the entire winter season.
