Furnace Service FAQs

Why Does My Furnace Turn Off and On?

The most common reason furnaces “short cycle,” or turn on and off frequently, is due to a dirty air filter. Dirty furnace air filters can restrict and clog air from reaching your heat exchanger, which causes your furnace to overheat and shut down. 

The culprit could also be a faulty or improperly placed thermostat. It may be that your thermostat is placed near a heat source like sunlight, a heat register, or fireplace. This causes the thermostat to think your home is warmer than it is, triggering the furnace to turn off early and often.

Another possible cause of short cycling is that your furnace hasn’t been sized correctly for your home. A furnace that is too large for your home heats the area too quickly and shuts off. Then, once your home cools off the cycle repeats.

It’s best to let a Levco technician diagnose the issue. We can provide the best advice and service to make sure your furnace is working at top efficiency.

Regular inspection can prevent frequent cycling issues by ensuring filters and components are clean and functioning correctly. An investment in a smart thermostat can also help maintain desired temperatures effectively, allowing seamless communication with your furnace.

Why Does My Furnace Keep Running?

More often than not, furnaces run constantly because the thermostat fan setting is turned to “on.” To correct this, change the setting to “auto” and turn the thermostat to a temperature that’s lower than the current room temperature. You should start to hear the furnace cycling after a few minutes.

Continuous running might also indicate the need for system recalibration or that there may be an issue with the thermostat itself, such as improper settings or wiring problems. Routine maintenance can usually catch these errors early, ensuring your furnace doesn’t operate excessively, which can lead to higher energy consumption and costs.

Why Is My Furnace Blowing Cold Air?

You should first investigate  your furnace’s fan setting. If your fan is set to “on” it means  your furnace blower is running even when the furnace isn’t producing warm air. Change the fan setting to “auto.” This ensures that the blower only runs when the furnace is actively heating the air.

Another common cause could be a dirty air filter which we mentioned in the question above. Dirty air filters restrict airflow to the furnace’s heat exchanger, causing your furnace to shut down and cold air to build up. Replace your air filter and you should start to feel warm air again..

Finally, check your pilot light. If the pilot goes out, your furnace is trying to run without a heat source. To get the light lit again, follow the manufacturer’s instructions on the unit, or call Levco for advice.

Regular tune-ups can identify potential ignition issues before they result in cold air emissions. Ensuring the furnace has the right fuel levels, especially in oil or propane systems, is also key to preventing this problem from recurring.

What Should I Do if My Furnace Thermostat is Not Responding?

Furnace thermostats that appear unresponsive typically indicate a problem with the power supply or internal components. Start by checking whether the thermostat’s batteries need replacement or whether the unit is properly connected to the home's power system. Incorrect settings can also be a cause, so ensure the thermostat is set to the desired function, whether heating or cooling. If the thermostat is programmable, ensure it is correctly adjusted to your daily schedule to avoid disruptions in operation. If these measures do not resolve the issue, then the problem might involve wiring or a software glitch. This is where calling a professional technician becomes essential.

Our team can evaluate and repair or replace a faulty thermostat, restoring full control over your furnace's operation. Keep in mind that older models feel less responsive due to wear and age and a new, smart thermostat could be a worthy upgrade offering improved control, energy savings, and seamless integration with your home’s heating system.

How Can I Ensure Furnace Operation During Power Outages?

With Connecticut experiencing its share of severe weather conditions, power outages are not uncommon. Ensuring your furnace operates during such times is critical for maintaining home comfort. One solution is investing in a whole-house generator that automatically supplies power for essential appliances, including the furnace, during outages. Not only does this ensure continuous heating but also protects other systems like sump pumps or refrigeration. It is important to regularly maintain and test your generator to ensure it activates when needed.

Alternatively, you may consider furnishing your home with a battery backup system, which acts similarly to generators but tends to be less labor-intensive and require fewer resources to maintain.

We recommend consulting with experts who understand local laws and regulations concerning generator installations to ensure compliance and safety. These precautions enhance the reliability of your heating system in Connecticut’s unpredictable climate.
