Performing an annual furnace tune-up is a great way to make sure your heating system is ready for the frigid winter months. It’s best to do heating system tune-ups proactively in the fall so you can be sure that you can keep your furnace running smoothly when you need it most.

Using our regular HVAC maintenance checklist for facilities managers throughout the year will make your furnace tune-ups faster and easier. That’s because regular maintenance will prevent breakdowns that may cause additional wear on your furnace system. There will be less to tune up later if your maintenance schedule keeps everything in good shape.

Understanding Furnace Maintenance

A furnace is a device that heats homes and buildings. It works by drawing in cold air, cleaning it through a filter, heating it with a gas or electric burner, and then distributing the warm air throughout the space via ducts and vents. Furnaces are important because they keep indoor spaces warm and comfortable during cold winter weather.

A functional furnace can also help solve air conditioning challenges. It may sound strange that a heating system can help solve issues with your cooling system. However, the reason for this unexpected benefit is that efficiently heating your building helps maintain a consistent, stable temperature. Doing so makes your air conditioning unit more effective.

Still, no HVAC system can function well if it’s miscalibrated. If you notice any of these signs during a furnace inspection, it may be time to call a professional to check and adjust your furnace’s settings. Here is what you should look out for:

Temperature Variations

If the actual room temperature differs significantly from the set temperature on the thermostat, it may indicate a miscalibration. Another sign may be uneven heating in different rooms.

Frequent Cycling

Miscalibration can cause the HVAC system to turn on and off more frequently than necessary. Take note if your furnace seems to turn on and off at unexpected or seemingly random intervals.

Increased Energy Bills

A miscalibration may lead to higher energy consumption and, therefore, increased utility bills. If your energy bills are much higher than anticipated, make sure your furnace is running efficiently.

Dust Accumulation

Dust and debris on the thermostat can affect its accuracy, potentially leading to furnace miscalibration. Thermostat cleaning should be part of any HVAC maintenance checklist for facility managers.

Furnace Maintenance Tasks

Check Thermostat Calibration

Verify that the thermostat accurately reflects the desired temperature. If it’s too low during your heating season, your building’s occupants will be uncomfortable. Too high, and you’ll needlessly increase your bills and your furnace’s wear.

Ensure System Operation

Test the furnace to ensure it starts, operates, and shuts down correctly. You should perform this task even if you have a new furnace.

Inspect the Heat Exchanger

Examine the heat exchanger for cracks, corrosion, or any signs of wear. Proactively schedule repairs if needed.

Examine Venting

Inspect the venting system to ensure proper exhaust of combustion byproducts. Make sure any buildup or debris doesn’t block the vent.

Check Electrical Connections

Inspect all electrical connections, including wires and terminals. Due to the wiring’s increased wear and potential lack of modern design standards, this inspection is especially crucial for older HVAC systems.

Inspect Gas Lines

Ensure that gas lines are properly connected and free from any signs of damage or corrosion. Potential gas leaks require immediate repair for safety reasons.

Check Air Filters

Examine and replace air filters if needed to maintain optimal airflow. This task will ensure your furnace’s efficiency.

Examine the Quality of the Installation

Verify that the furnace complies with safety standards and manufacturer specifications. An older furnace is at higher risk of violations, but newer furnaces need to be checked, too.

Inspect the Area Around the System

Ensure that the area around the furnace is clear of any combustible materials. Dust buildup is especially a risk inside the furnace cabinet.

Document Equipment Information

Record essential information, such as the model and serial numbers of the furnace. Logging this information will help an HVAC technician perform the correct procedures when needed.

Regular Maintenance of Thermostat

Regular maintenance of a thermostat is essential to ensure accurate temperature regulation and extend the device’s lifespan. Prevent deferred maintenance as much as possible to uphold consistent furnace performance.

Clean Thermostat

Remove dust and debris from the thermostat’s exterior to ensure accurate readings. Use a soft brush or compressed air for delicate components.

Check All Electrical Connections

Check for any loose or damaged wiring connections and seek a replacement for damaged wires as soon as possible.

Examine the Physical Damage

Visually examine the thermostat for cracks or breakage. Assess if the damage warrants repair or replacement and act accordingly.

Replace Batteries

Replace the batteries promptly to prevent interruptions in service. Be sure to replace the batteries before they die. Replace them when they are running low.

Check Calibration

Compare a thermostat reading with an accurate thermometer. Adjust temperature settings if a variance is detected.

Ensure Proper Location

Confirm that the thermostat is not exposed to direct sunlight or drafts. Otherwise, it may pick up on these temperatures and produce an inaccurate reading.

Furnace Tune-Up Strategies

Schedule Professional Maintenance

Regular professional maintenance by a certified HVAC technician is crucial for identifying and addressing potential issues. Such proactive maintenance will extend the furnace’s life and decrease TCO in facilities management.

Clean The Heat Exchanger

Cleaning the heat exchanger ensures optimal heat exchange efficiency and reduces the risk of carbon monoxide leaks. It can also extend the lifespan of the furnace by preventing corrosion and damage.

Lubricate Moving Parts

Moving components, such as the furnace’s blower motor, need proper lubrication to minimize friction and reduce wear and tear. Regular furnace cleaning ensures that dust and debris don’t get stuck in your lubrication.

Replace Air Filters

Air filters trap dust and debris, preventing them from entering the furnace. Clean filters contribute to optimal airflow and system efficiency.

Perform a Carbon Monoxide Test

Carbon monoxide (CO) is a colorless, odorless gas that is dangerous if inhaled. Testing ensures there are no leaks and the furnace is venting properly.

Find a Reliable Furnace Service Provider

Check the technicians’ qualifications, such as certifications and training in the latest furnace technology. Evaluate the range of services offered to ensure they can meet your specific furnace needs. Finally, you’ll need to confirm their availability for routine maintenance and emergency repairs.
