Easy Furnace Maintenance Tips to Stay Ahead of Furnace Repairs

1. Clean or Replace Your Air Filter

The air filter in your furnace plays a vital role in maintaining indoor air quality and your unit’s efficiency. Over time, dust and debris accumulate, clogging the filter. Regularly inspect and clean or replace it to keep the air flowing smoothly and help your furnace run efficiently. 

Common Issue: You can identify your need for an air filter replacement based on a harder running unit, less efficiency, and higher energy bills 

2. Check and Clean the Blower

A clean blower ensures that the warm air is distributed evenly throughout your home. Dust and debris can accumulate on the blower wheel, affecting its performance. Make it a habit to clean the blower and its components regularly. This will ensure a smooth-running furnace and cut back on HVAC repairs. 

Common Issue: Your blower will need to be checked and cleaned when you notice uneven heating, less heating, and a harder working unit. A visual inspection is the fastest way to avoid these issues. 

3. Inspect the Thermostat

The thermostat is the brain of your heating system. Every year, check to make sure it’s in good working order by checking the accuracy of the temperature readings. If your thermostat begins to have issues, you want to update it quickly so the proper directions are being sent to your furnace, avoiding unexpected malfunctions.

Common Issue: Thermostats are prone to dying out or having their batteries need to be replaced with frequent use. Always check the thermostat before assuming an issue with your HVAC unit. 

4. Lubricate Moving Parts

Proper lubrication of your furnace’s moving parts, such as the motor, can significantly extend your system’s lifespan and reduce overall wear and tear. Consult your manufacturer’s manual to determine the type of lubricant required and how often it should be applied. If you’re unsure, your local HVAC company can assist by putting you on an annual maintenance plan to help with upkeep. 

Common Issue: If your furnace makes loud abnormal noises or exhibits a rocking motion, lubrication may be your fastest solution. 

5. Examine Electrical Connections

Loose or corroded electrical connections can be a fire hazard and lead to furnace malfunctions. Carefully inspect all electrical connections and wires, checking to see if they are secure and undamaged. If you find any issues, it’s essential to have a professional technician address them promptly. Damaged electrical connections will cause a quick issue, one that is easily avoidable by a quick glance over. 

Common Issue: Electrical problems may be your issue if you note a change of light brightness when your furnace kicks on or other issues with your energy pull. Always consult a professional to diagnose and repair. 

6. Clean Your Air Ducts

Clean air ducts are vital for efficient air circulation and indoor air quality. Over time, dust and debris accumulate in the ducts, making your furnace work harder to maintain the desired temperature. Consider professional duct cleaning to keep the air in your home clean and your furnace running smoothly. This will also help reduce energy bills and reduce allergens circulating in your home.

Common Issue: Increase in allergens, dirt, or poor air quality will be your first indicator that you need air duct cleaning to improve your furnace. 

7. Schedule Annual Professional Maintenance

While most of these recommended furnace maintenance tips can be performed by homeowners, it’s crucial to schedule an annual professional inspection and maintenance service. Certified technicians can identify and address potential issues before they become major problems, ensuring the longevity and efficiency of your furnace. We recommend doing so once before Winter and once before Summer to ensure optimal performance before the harsher seasons.
