Common Types of Furnace Problems

If your furnace is older or outdated — if it’s been in use for more than 10 years — there are certain types of problems you might encounter when it’s on the decline. Below are a few of the more common types of problems concerning an older home heating unit:

Blower Runs Continuously

If your heating unit’s blower is constantly running, It could be the fan limit control switch needing replaced or it might need to be reset. With that said, however, it could also be the thermostat “FAN” setting, which would need to be switched over to its AUTO setting, which will enable the fan to only run when the system is heating or cooling.

Thermostat Is Faulty

After ruling out other common culprits with the furnace system itself, like the air filter and such, check your thermostat. Problems with an HVAC system’s thermostat can result in wild temperature swings, a furnace that produces no heat, or the unit cycling on and off too often. First make sure your thermostat has power and that there is no dust or debris in its components. If that doesn’t help, give us a call.

Lack of Heat

Once Ohio’s frigid weather starts setting in, it’s essential to make sure your home heating equipment is working properly and providing sufficient heat to keep your whole home warm throughout the winter. If your furnace stops producing heat or if it begins blowing only cool air, there are several possible culprits:


  • Verifying that the furnace has power
  • Making sure all heat registers are open
  • Checking settings on thermostat

Furnace Cycles On and Off Frequently

You can reduce energy costs and prevent damage to your expensive furnace by addressing issues of “short cycling.” This is important because in very cold weather, this constant turning off and on might be normal and necessary to keep your home at a comfortable temperature. However, it could also be a sign of a bigger underlying problem with your furnace. Possible causes include a dirty air filter, or a faulty thermostat, or a blocked exhaust vent.

Noisy Furnace

Noisey heating equipment usually indicates a problem developing that can turn into an expensive repair if not addressed early on. It could sound like a high-pitched squealing, a loud banging or just a low-pitched humming noise that’s distinct from the furnace’s normal hum. Often, it’ll save you money in the long run if you call a professional to have a look. It could be solved by replacing the filter, if air blockage is causing the noise, and oiling the blower motor.

Pilot Light Is Out

With older gas furnaces, the standing pilot light can go out if there’s a strong draft or if the equipment gets dirty. Additionally, the thermocouple could have gone bad, causing the gas supply to shut off. The pilot light going out is a fairly common reason for a gas furnace to fail to produce heat. Fortunately, in most cases relighting the pilot light is fairly straightforward and simple. If the thermocouple is faulty, replacement is easy, fast and affordable.

Mismatched Furnace and Thermostat

Furnaces and thermostats need to be properly paired with one another by a professional in order to function properly. Matching up the wrong type of thermostat with a heating unit will cause problems. One example would be the furnace might underheat or overheat the home despite how you set your thermostat. Because of this, it’s important to make sure you have installed the correct type of thermostat for your type of furnace.

Electronic Ignition Is Failing

Newer furnaces don’t rely on a standing pilot to ignite the gas burners. Nowadays, they usually use electronic components. Electronic ignition typically occurs in one of two ways: hot-surface ignition or intermittent pilot. A hot-surface ignition system utilizes an electronically controlled resistance heating element, not unlike a light bulb filament, to ignite the gas burner. ​​The intermittent pilot system uses an electronically controlled high-voltage electrical spark to ignite the gas pilot. It then lights the main burners when the thermostat relays the message for heat. If the electronic ignition has a problem, your furnace might produce little or no heat, it might cycle frequently, or you might have an overactive blower.

Troubleshooting a Furnace Not Heating

If your home heating system isn’t working like it should, or not working at all, we at Circleville Heating & Cooling present the following Furnace Troubleshooting Tips:

Start by making sure the thermostat is working properly:

  • Set the temperature a few degrees higher than the current room temperature.
  • Check device’s power source and batteries to ensure the thermostat has power.
  • Make sure the thermostat is in heat mode.

If the furnace doesn’t have power, it will not turn on, preventing heating.

  • Check the furnace’s power source at the breaker or fuse box.
  • Change fuses or reset breakers if needed.
  • Check the on/off switch near the furnace or air handler to make sure it is set to on.

If the furnace does not have fuel, it can’t produce the heat you need.

  • If you have a propane or oil furnace, make sure you have fuel in the tank available for heating.
  • Make sure the gas supply valve to the furnace is on.

The furnace may not be heating because the motor has been overloaded, requiring reset.

  • Use the reset button, located on the side or front of the furnace.

Issues Causing Furnace Not to Heat

If your furnace is older and it uses gas, a faulty pilot light can be the reason your system isn’t heating. There are several reasons the pilot light might not want to stay lit. We would be happy to diagnose the source of the problem and make the repairs necessary, which could be replacing the safety cutoff valve, replacing the thermocouple, cleaning the pilot light’s orifice, or adjusting the flame. If you have a dirty flame sensor, the furnace won’t function properly because this safety feature is in place to prevent unsafe burning. Because of this, the flame sensor may require adjustment or cleaning.

Should I Repair Or Replace My Furnace?

Anytime a furnace breaks down, repairing it can be quite expensive depending on the problem. Having said that, if you find yourself having to repair your home heating system more and more often, you may wonder whether it’s better to repair your furnace or replace it. Below we list seven essential questions and answers that will help you decide whether to repair or replace your furnace:

1. How Old Is My Furnace Now?

Furnaces usually last around 15 years at least, and often even longer if they’re properly serviced and maintained over the years by a professional. Nevertheless, as a furnace gets older, shelling out for expensive repairs makes less and less sense.

2. What Condition is the Furnace In?

Investing in repair parts and labor on a system that’s been running beautifully is usually well worth the money. However, if the furnace is loud, rusty, sooty, blowing cold air and running up your heating bill, it might be time to say goodbye, especially if there’s any safety issues.

3. What’s the Projected Cost Of Repairs?

This question also ties back to the previous two questions. The age and condition of your furnace will help you determine how much you should spend for repairs.
For example, spending a few hundred dollars on a furnace that’s middle-aged isn’t unreasonable. However, if the repair estimate comes to more than a thousand, your money is probably much better spent investing in a new model.

4. Will A New Furnace Save Me?

Advances in HVAC technology are shocking to some customers. Today’s furnaces are far more energy-efficient than those of even a few years ago. If you install a new unit, you can confidently expect your fuel bills and your carbon footprint to drop.

5. Questions About Air Quality & Temperature Control

A new furnace can provide superior home comfort in a variety of ways. For example, you can add on an air purifier or whole-house humidifier in your furnace to improve indoor air quality. You can also set up your new furnace so that you can set your heating at different temperatures in different zones of your home.

6. Are There Any Rebates Or Special Offers For A New Furnace?

Take advantage of special offers and deals that will make the purchase of a new home heating system more affordable. You could qualify for a program such as the Home Efficiency Rebate, which is offered to incentivize upgrading your home’s energy efficiency.

7. What Will My Budget Cover?

To make this determination, you will have to crunch the numbers and see what you can afford. When you balance the cost to repair or replace a furnace, usually the repair has a lower upfront price tag. However, rebates and special offers (as outlined above), combined with your potential savings on fuel bills, can turn furnace replacement into a much more budget-friendly option.
