Furnace Keeps Starting And Stopping-How to fix?

Picture this: it’s a blustery winter day. The wind is howling and the snowflakes are swirling. You’re indoors, cozy and warm. Or at least, you should be. Instead, you’re noticing an annoying trend. Your furnace keeps starting and stopping. You’re not alone in this frustration. Many homeowners face this same issue, commonly referred to as short cycling. How can this problem be diagnosed and, even better, fixed? We have researched and compiled some valuable insights ahead.

Understanding the Issue at Hand

When your furnace keeps starting and stopping, a phenomenon known as ‘short cycling,’ it means there’s an underlying issue that requires immediate attention. Not only is short cycling frustrating due to the inconsistent heat, but it is also inefficient and can cause higher energy costs. Additionally, it leads to excessive wear and tear on your furnace, possibly leading to premature failure of the unit.

The Probable Culprits and Their Solutions

Several factors can cause short cycling, and understanding them can help you address the issue more effectively.

1. Overheating: If your furnace is overheating, it may shut down to protect its internal components. This is often due to a dirty air filter that’s blocking airflow, causing the furnace to work harder than necessary. The solution in this case would be as simple as replacing the air filter regularly.

2. Thermostat Issues: Another common cause is a malfunctioning thermostat. If the thermostat is incorrectly calibrated, it may cause the furnace to start and stop frequently. A professional can help correct this calibration, or, if necessary, replace the thermostat.

3. Oversized Furnace: Based on our research, another often-overlooked cause of short cycling is an oversized furnace for the space it serves. If your furnace heats your home too quickly, it may shut off before correct circulation occurs.

The Importance of Seeking a Professional

While some fixes, like replacing the air filter, are simple DIY jobs, others, such as thermostat calibration or furnace downsizing, require professional intervention. According to the U.S. Department of Energy, in 2019, 13% of US homes’ total energy consumption can be attributed to heating. This statistic emphasizes the impact a well-functioning furnace can have on both comfort and wallet. Therefore, when a furnace keeps starting and stopping, finding and fixing the problem promptly can save a lot of headaches.

The Perks of Regular Furnace Maintenance

One proactive measure to ward off short cycling and other furnace-related issues is regular maintenance. A thorough annual inspection can help identify potential problems that could lead to the furnace starting and stopping more frequently than necessary.

Whether you’re dealing with a furnace that’s short-cycling or looking to prevent the problem from happening, remember the importance of understanding the potential causes. From replacing air filters to recalibrating thermostats, these solutions can help ensure the longevity of your home heating system. And when in doubt, seek professional advice to ensure your furnace works optimally, providing you the comfort you need irrespective of the weather outside.

Summing it up

No one likes the idea of stepping out from a warm blanket into a cold house, only to find the furnace is on an unexpected break. The cold reality of a furnace that keeps starting and stopping is a problem that needs resolution. Recognizing the importance of a correctly functioning furnace, coupled with understanding common short-cycling triggers, can provide the heat of comfort in the chill of uncertainty.
