5 of the Most Common Furnace Problems

Some of the most common furnace problems happen more frequently than others and, in some instances, are relatively easy to fix. Take a look at some of the most common furnace problems below.

1. Your Furnace Is Not Producing Enough Heat

Your furnace’s primary job is to circulate warm air throughout your home. While a furnace that is failing to generate heat is a cause for concern, the problem could actually be with your thermostat. In addition, dirty filters can prevent the flow of heat in your home. Check the thermostat or air filter to see if either one of them is the problem.

2. Your Furnace Is Repeatedly Turning On and Off

As your furnace heats your home, it typically cycles on and off to keep the temperature at the desired level. If you find that your furnace is repeatedly switching on and off or it is only working for a few minutes at a time, your problem may be a clogged filter.

3. Your Furnace Is Not Turning on Automatically

If all is well and good, your furnace will turn on and generate heat as soon as it receives a signal from the thermostat. However, if you’ve found that it doesn’t promptly turn on, try checking your breaker box. Flipping the furnace safety switch may solve the problem.

4. Your Furnace Just Plain Stopped Working

If your furnace isn’t heating your home at all, it could be a problem with your boiler or thermostat. If you can’t determine the issue, then you should call a professional to come repair or replace your furnace. Nobody wants to be stuck in the middle of winter with a faulty furnace!

5. Odd Noises Are Coming From Your Furnace

Any instances of squeaking, rumbling, scratching, or rattling noises coming from your furnace are all indicators of a mechanical problem. Most furnaces will create some slight noise, as they run continuously. However, if you notice anything that sounds blatantly noticeable, you should call an emergency furnace repair service to schedule an inspection.

Tips for Maintaining Your Furnace

While there are times when a furnace problem needs the attention of an experienced technician, in other situations, the problem might be something that could be prevented in the future. If you start to notice problems, run through these basic furnace troubleshooting measures to see if it’s a problem you can fix on your own.

Replace the Air Filters Every Three Months

A clogged filter can have a drastic impact on your furnace’s ability to do its job. Luckily, changing the filter is one of the easiest, albeit most important, maintenance tasks you can perform. Replacing the filter every three months can increase indoor air quality and extend the life of the furnace. If it’s been a while since you inspected the air filter, it may be a good idea to replace it with a new one.

Regularly Check Your Unit When It’s Not in Use

Even when not in use, power up your furnace at least once every season to ensure that it is working properly. Switching on the furnace will help you detect any underlying issues, such as excessive dust in the filters, which can restrict airflow. If you notice anything serious, then you should contact a professional.

Clean the Vents and Ducts

Ensure that all vents and registers are open and that nothing is obstructing the vents to ensure proper airflow and circulation in your home. Additionally, cleaning the ductwork will help keep the furnace running correctly and avoid potential damage.

Schedule Routine Maintenance With an HVAC Professional

Lastly, you should have an HVAC specialist inspect, test, and perform maintenance on your home heating system every year. Regular maintenance will help increase your furnace’s performance and prolong its lifespan.
