After a long day of work, it’s always nice to walk into your warm and cozy home in Oakland, Missouri. But what if your furnace stops blowing warm air and the temperature inside drops? There could be a number of issues causing the problem. Keep reading to learn about three common reasons a furnace won’t blow hot air.

The Thermostat Isn’t Set Properly

One of the most common reasons a furnace won’t blow hot air is because the thermostat accidentally got turned off the heat setting. Another culprit could be a temperature that’s set lower than you prefer. If your system isn’t blowing hot air, checking the thermostat and its settings is a smart first move. You may find a simple adjustment will fix your furnace problem.

You Need to Change the Filter

Most homeowners know they should regularly change or clean the filter on their HVAC systems during the cooling seasons. However, many fail to realize they must give the same attention to filters during the heating seasons, too.

A dirty or clogged filter minimizes the furnace’s ability to blow hot air. As a result, it makes the system work harder and negatively impacts indoor air quality. Inspecting and changing the air filter once a month is ideal and may remedy the issue of the furnace not blowing hot air.

The Pilot Light is Out

Another common reason the furnace won’t blow hot air is because the pilot light has gone out. If you notice the pilot light is out, you’ll need to relight it. But because any type of furnace maintenance can present safety issues, you should always leave these tasks to a professional. A heating contractor can inspect the pilot light and will know the easiest and safest way to relight it.
