Your furnace works hard to keep you comfortable throughout the year. Like any machine, it needs regular maintenance to keep it running in peak condition. With proper maintenance from a qualified professional, you can enjoy optimal performance and energy efficiency as well as peace of mind knowing your system is safe and reliable. Here’s an overview of the essential furnace maintenance that’s generally included in a yearly tune-up.

Air Filter Changes

All furnaces have some type of filter that captures dust and particles. This filter helps maintain the air quality in your home and protects important components of the system, such as the blower motor. To keep these parts working optimally, it’s essential to change or clean the filter regularly. This typically happens every one to three months.

Vent System Inspection

During a furnace tune-up, your technician will check the main vent system and exhaust ducts. This is to make sure there are no clogs or blockages that could prevent carbon monoxide from escaping safely.

Heat Exchanger Inspection

The heat exchanger is a key component of any furnace. It’s what generates the hot air that circulates throughout your home. When operating correctly, it helps ensure energy efficiency and limit emissions of carbon monoxide. During routine maintenance, your technician should inspect the heat exchanger for cracks or signs of corrosion so they can take action before it becomes an issue.

Blower and Motor Inspection and Cleaning

Your furnace’s blower fan and motor are responsible for pushing air throughout your home. During a tune-up, your technician will check the bearings, belts, and other components of the motor to ensure they’re in good working order. They may also clean around the motor and remove any dust that has built up over time.

Electrical Connection Testing

Your technician will also check the electrical wiring and connections to make sure they’re up-to-date. This is important for safety since any faulty components or improper wiring can be a fire hazard.

Burner and Flame Sensor Check

The burner and flame sensor are what generate heat within your furnace. Your technician will check that the burners are clean and free from dirt, dust, and debris, which can create a fire hazard if left unchecked. They’ll also make sure the flame sensor is working properly so it can detect any issues with the ignition system as soon as possible.

Thermostat Calibration

Thermostats regulate the temperature in your home, so it’s important to make sure they’re calibrated correctly. During a tune-up, the technician will check and adjust the thermostat to make sure it’s able to accurately detect changes in temperature and respond accordingly.


The moving parts of your furnace should be lubricated to keep them running smoothly and reduce wear and tear. Your technician will apply the appropriate type of lubricant to any components that need it, such as blower motors and fan belts.

Fuel Line Inspection

If your furnace uses natural gas, propane, or oil for fuel, your technician will check the fuel line for any signs of corrosion, leaks, or blockages. This is an important safety measure to make sure the fuel is delivered properly and without any interruptions.

Thermocouple Inspection

Gas furnaces also have a component called a thermocouple, which is responsible for detecting the pilot light. Issues with the thermocouple can cause the pilot light to become extinguished, which can prevent your furnace from heating your home. Your technician will check this part of the system to ensure it’s doing its job correctly.

Gas Pressure, Burner, and Pilot Light Check

For gas furnaces, your technician will check the amount of gas pressure in the system and verify that the burner is producing a clean flame. They’ll also make sure that the pilot light is correctly adjusted and burning a blue flame rather than a yellow one, which can be a sign of carbon monoxide leakage.

By the end of the furnace tune-up, your technician will provide you with a detailed report that outlines any issues they found and any recommendations for repairs or further maintenance.
