Furnace Repair: Tips and Tricks for a Quick Fix

When warm air stops flowing in through your vents, often the first instinctive reaction is to panic. Furnaces are complex systems that require a certain level of skill and knowledge to properly diagnose and repair. However, certain small repairs can be easily handled by homeowners who are equipped with the right tools and tips. Before calling a professional to send over a technician, here are some furnace repair tips and tricks that might help get your furnace up and running in no time.

Pre-Troubleshooting Tips

When your furnace is not working as it should, there are some steps you can take before trying to pick apart the system to fix it. It is important to remember that, despite the fear that you might have caused more damage, most furnace issues can be easily solved.

Check the Blower Motor. Begin by disconnecting the power from the unit, then remove the inside panel to reach the blower motor, if accessible. First, make sure that the motor is securely connected to the blower wheel and that there are no signs of damage to the wheel. Use your hand to spin the wheel and make sure that it is spinning freely. If you think there is an issue, spin it and then replace the paneling.

Inspect the Furnace Filters. It is important to regularly remove, inspect and replace your furnace filters to keep your system in working order. If the filters are severely clogged, they can restrict the air flow, causing stress to the blower and numerous other potential problems.

Ensure Proper Voltage. When dealing with the electricity of a furnace, it is important to always follow safety protocols. Make sure the switch is off, and then set a multimeter to voltage in the AC range. Connect the meter to each of the furnace wires and measure the volts. The voltage should be close to 24 volts when the thermostat call for heat. Anything higher could potentially cause significant damage.

Finding The Problem

Once you have gone through the initial pre-troubleshooting steps, it is time to assess the actual furnace for the source of the issue.

Check the Gas Pilot Light. Inside of the gas furnace, you should find a gas pilot light. If the light has gone out, the furnace will never ignite. Check your owner's manual to learn how to relight the pilot light. Be sure that the thermocouple is sensitive enough to detect the flame.

Inspect the Heat Exchanger. The exchanger is responsible for transferring heat inside the chamber. If cracked, the exchanger can leak deadly carbon monoxide. In addition, it can also emit an unpleasant odor into the room.

Inspect the Thermostat. If the pilot light is on and the problem persists, the thermostat might be failing to work. Check the wiring to the thermostat and ensure that it is properly connected and set.

Troubleshooting Tips

When attempting to diagnose the furnace, there are some troubleshooting tips that can help you better understand the issue.

Check for Strange Sounds. Strange sounds coming from the furnace can indicate a major issue. Rattling, squealing and banging noises should be looked at and inspected immediately.

Double Check Your Pilot Light. Many furnace issues can be attributed to an unlit or partially lit pilot light. Double check the light and make sure that it is lit.

Monitor Your Thermostat. If you can see a flame, check the thermostat for changes in temperature. If the temperature does not change and the furnace does not respond, a part may be failing.


Furnaces are complicated systems and require certain levels of skill and knowledge to properly diagnose and repair. Before calling a professional, it is important to take note of the pre-troubleshooting and troubleshooting tips listed above. Especially if you have done your research and understand the basics of DIY furnace repairs, you can save yourself time and energy by avoiding expensive fees and waiting for a technician to show up. By taking these simple steps, you have a higher chance of quickly solving the furnace issue yourself, or at least identify the problem more accurately for a technician to solve it.

Furnace Repair: Tips for Avoiding Issues

PLEASE adhere to the following recommendations to help reduce the likelihood of needing furnace repair.

$$ Yearly Maintenance

PLEASE ensure that you have an annual maintenance executed on your system, as this helps to ensure potential issues are caught early. An HVAC contractor can assess if any parts need to be replaced, cleaned, and/or adjusted to keep your system working properly.

$$ Filter Change

PLEASE be diligent in replacing the filters regularly in order to keep your system running efficiently and safely. To maintain efficiency, the filter should be changed at least every three months, or more frequently if pets are present in the home.

$$ Proper Ventilation

PLEASE make certain that any unvented combustion appliances such as space heaters have the proper vents installed according to the manufacturer's instructions. This will help to reduce the risk of exhaust gases being released into the living space and also reduce any potential system failures.

$$ Seal Leaks and Gaps

PLEASE check for and seal any air leaks in the ductwork, around windows and doors, and other areas where air may be escaping. This can help to reduce the load on the furnace, as the unit will not need to continually cycle on and off. Additionally, any gaps between the base of the unit and the floor should be sealed with insulation to prevent conditioned air from escaping.

$$ Thermostat Settings

PLEASE make sure that the thermostat is set correctly, to avoid unnecessary strain on the system. The temperature should be kept at a consistent level during both the heating and cooling seasons. Additionally, check to see if the fan setting is working correctly and adjust the setting if necessary.
