Having a working furnace is essential for keeping your home warm and comfortable during the winter months. However, like any appliance, furnaces can break down or develop problems over time. 

Performing regular maintenance and being aware of common furnace issues can help you avoid unexpected repairs or replacements. This guide will provide tips for keeping your furnace in top condition.

Schedule Annual Tune-Ups

One of the best ways to prevent furnace problems is to have a professional perform a tune-up at the start of every heating season. During a tune-up, the technician will inspect components like burners, heat exchangers, blower motors, filters, belts, and more. 

They can clean parts, make adjustments, and spot potential problems before they lead to bigger issues. Annual tune-ups help improve efficiency and may extend the life of your furnace.

Change Filters Regularly

Furnace filters play a crucial role in trapping dust, dirt, and allergens. When filters become clogged with debris, less air can circulate through your furnace. This forces the system to work harder, leading to potential breakdowns. 

Check your filters every 1-3 months during the heating season. Disposable filters should be changed, while reusable filters can be cleaned.

Look Out for Warning Signs

Pay attention to any odd sounds, smells, or problems coming from your furnace. Unusual noises like banging, screeching, or vibrating could indicate an issue like a loose part or a motor problem. 

Smelling gas, burning smells, or seeing smoke are emergency situations requiring immediate attention. Other signs of trouble include frequent cycling, not reaching the desired temperature, or rooms feeling drafty and cold.

Maintain Proper Temperature Settings

Running your furnace at the recommended settings can help it operate most efficiently. Setting your thermostat too high can overwork the furnace while allowing the temperature to dip too low leading to more frequent cycling and reheating. 

Keep daytime home temperatures between 68-72°F and around 60-65°F at night or when away. Also, be sure to change filters when switching from cooling to heating modes.

Address Small Problems Quickly

The Minor heating repair done early on can prevent more extensive breakdowns. For example, replacing a faulty pilot light ignitor or realigning a contactor switch may be simple fixes that restore normal operation. 

Loose belts or clogged drain lines can also cause furnace problems when left unchecked. Diagnose issues early and address small repairs right away before they become big problems.

Consider Replacing Older Units

Older furnaces tend to have more frequent breakdowns, higher operating costs, and safety risks. If your furnace is near or past this age range, it may be time to consider replacement, especially if repairs are becoming complicated or expensive. Newer models are much more energy efficient and have advanced safety mechanisms.

Hire Professional Repair Experts
