Reasons Your Furnace is Still Running After Reaching the Set Temperature


During the cold winter months, we rely on our furnaces to keep our homes warm and comfortable. However, there may be times when we notice that our furnace continues to run even after it has reached the set temperature. This can be a cause for concern, as it may indicate that there is an underlying issue with your heating system. In this blog post, we will explore some common reasons why your furnace may still be running after reaching the set temperature.

1. Incorrect Thermostat Settings:

One of the most common reasons why your furnace is still running could be due to incorrect thermostat settings. Ensure that your thermostat is set to the desired temperature and that it is not set to the “continuous” or “fan” mode. In these modes, the fan or heating system will continue to run regardless of the actual temperature in your home. Double-checking your thermostat settings can help resolve this issue.

2. Dirty Air Filters:

Another common culprit for a furnace that keeps running is dirty air filters. Over time, air filters can become clogged with dust, debris, and other particles, inhibiting proper airflow. When the airflow is restricted, it can take longer for your furnace to reach the set temperature, causing it to continue running. Regularly changing or cleaning your air filters can help prevent this from happening and also improve the overall efficiency of your furnace.

3. Thermostat Placement:

The placement of your thermostat can also contribute to your furnace running longer than necessary. If your thermostat is located near a window, vent, or any other source of drafts, it may receive inaccurate temperature readings. This can trick your furnace into thinking that the temperature has not yet reached the desired level, causing it to keep running. Consider relocating your thermostat to a more central area in your home to avoid such issues.

4. Leaky Ductwork:

Leaky ductwork can lead to warm air escaping before it reaches the desired areas of your home. When this happens, your furnace will continue to run in an attempt to compensate for the lost heat. Sealing any leaks in your ductwork can help resolve this issue and improve the efficiency of your furnace.

5. Malfunctioning Thermostat:

If you have ruled out the other common causes and your furnace still runs continuously, it is possible that your thermostat is malfunctioning. A faulty thermostat may not accurately measure the temperature or send the correct signals to your heating system, causing it to run longer than necessary. If you suspect a malfunctioning thermostat, it is advisable to contact a professional HVAC technician to diagnose and replace the thermostat if needed.

6. Oversized Furnace:

An improperly sized furnace can also be a reason why it continues to run after reaching the set temperature. A furnace that is too large for your home will heat it quickly, but it may shut off before the whole space reaches the desired temperature. As a result, the furnace will turn back on soon after, leading to constant cycling. If you suspect that your furnace is oversized, consult a professional to evaluate your heating needs and recommend the appropriate furnace size.


There can be various reasons why your furnace is still running after reaching the set temperature. Checking your thermostat settings, regularly changing air filters, ensuring the proper placement of the thermostat, sealing leaky ductwork, and addressing any thermostat malfunctions are all important steps in troubleshooting this issue. It is also worth considering the size of your furnace to ensure it is appropriate for your home’s heating needs. If you are unsure or unable to identify and address the problem, it is always best to contact a professional HVAC technician to diagnose and resolve the issue to ensure the optimal performance of your furnace.

A dirty exchanger can reduce your energy efficiency and raise your heating costs. It can also be dangerous, as it can release fumes that are harmful to your family and home environment. The best way to clean your furnace is to call in a professional HVAC technician. This is especially true if your exchanger isn’t working properly or needs repair. To clean your furnace heat exchanger, start by removing it from the front of the unit and disconnecting it from electricity. You will need a pipe brush and a cleaning solution to complete the job.

Clean The Combustion Chamber

Your furnace’s combustion chamber contains the flames and burners that heat your home. Over time, soot can build up in this area. If left untreated, the soot can corrode the walls of the chamber and cause carbon monoxide to leak into your home. To avoid this, the combustion chamber needs to be carefully cleaned on a regular basis. Contact us today to learn more!

Follow These Tips To Prepare Your Furnace and AC for the Winter

When it’s that time of year again — when the leaves change color and the days get shorter — you know winter is just around the corner. This means it’s time to start thinking about preparations for the cold weather ahead. One of the most important things to take care of is your home heating and cooling system. In this blog post, we’ll provide you with some tips on how to maintain your furnace and prepare AC unit for winter.

1. Change the Filter

One of the most important things you can do to prepare your furnace for winter is to change the filter. A dirty filter will not only make your furnace work harder, but it can also lead to health problems for you and your family. Be sure to check and change the filter according to the manufacturer’s instructions. If you have a reusable filter, simply rinse it off with water and let it dry completely before putting it back in the furnace. If you have a disposable filter, replace it with a new one of the same size and type.

Most filters should be changed every three months, but if you live in an area with a lot of dust or pet hair, you may need to change it more often. Another important tip is to make sure a professional properly services your furnace before winter starts. This will help ensure that your furnace is running efficiently and safely. When the cold weather hits, you’ll be glad you took the time.

2. Inspect the Furnace

If you have a gas furnace, it’s important to get it inspected by a professional every year. This is because there is the potential for carbon monoxide poisoning if there are any leaks in the system. If you have an electric furnace, you don’t need to get it professionally inspected, but you should still take a look at it yourself to make sure everything looks clean and in good working order.

Dust around the furnace, as this can be a fire hazard. Also, check the pilot light to make sure it’s still lit. If you have any doubts about anything, it’s always better to call a professional for an inspection.

3. Schedule a Tune-Up

Just like your car, your furnace or AC unit benefits from a tune-up before the winter season. All the moving parts need to be lubricated and checked for any potential issues. A professional HVAC technician will also clean out any dirt and debris that may have accumulated over the summer months. This tune-up will help your system run more efficiently and prevent any breakdowns during the winter.

4. Check the Thermostat

Your thermostat controls the temperature in your home, so it’s important to ensure it’s working properly. Test it by setting the temperature lower than the current room temperature and see if the furnace turns on. If not, there may be an issue with the thermostat that needs to be addressed.

5. Clear the Area Around the Outdoor Unit

If you have a central air conditioner, the outdoor unit must be clear of debris or obstructions. This includes things like leaves, branches, and other yard waste. If the unit is obstructed, it won’t be able to work properly and could overheat. Furthermore, if snow or ice accumulates on the unit, it’s important to remove it so the unit can function properly.

How To Prepare Furnace for Winter
