3 Things to Check When Your Furnace is Not Heating

It’s the middle of winter, and your furnace isn’t working! What do you do? Well, before you call the repairman, there are a few things you can check on your own. This article will discuss three things to check when your furnace is not heating properly. We will also talk about when it’s time to call in the pros!

1. Check the Thermostat

The first thing to check when your furnace is not heating is the thermostat. Make sure it is set to a temperature that is higher than the temperature in your home, and also make sure that it is on “heat” or “auto” mode. If you are using a programmable model, make sure all the settings are correct. This is usually an easy fix and could save you a service call! However, if you are unsure how to adjust your thermostat, it’s best to call a professional in  heating in Atlanta service. They’ll have the necessary tools and knowledge to adjust the thermostat properly.

2. Check the Furnace Filter

The next thing to check is your furnace filter. A dirty or clogged filter can cause your furnace to work harder and not heat properly. Change the filter as often as recommended by the manufacturer (usually every couple of months). If you haven’t changed it in a while, that could be the cause of your heating issues. It is recommended that you replace your filter once a year for optimal performance. This will not only help your furnace to heat more efficiently, but it will also help your furnace and air conditioner last longer.

3. Check the Pilot Light or Ignition System

If you have an older model furnace, you may have a pilot light that needs to be lit in order for the furnace to work properly. If the pilot light is out, try relighting it. If you have an electric furnace, check the ignition system to ensure it is working properly. Again, if you are not confident in your ability to do this, it may be best to call a professional furnace repair company. In addition, it will also benefit from knowing what is the ideal schedule for servicing a furnace, as this will ensure it runs safely and efficiently. This will also benefit you in terms of the extended lifespan of the system.


Knowing how to troubleshoot common furnace problems will save you both time and money. But when it comes down to your furnace performance, it’s better to be safe than sorry. Even if you are handy around the house, some problems require special tools or knowledge that only experienced HVAC professionals have.
