Common Furnace Problems And How To Address Them

Posted on: 30 January 2024

It’s winter season again, and you’re looking forward to cozy evenings at home. But what if your furnace stops working? It is not uncommon for homeowners to encounter furnace issues during the cold months, and if not addressed on time, these problems can escalate into bigger and costlier repairs. Here are some common furnace problems you might face and what you can do to fix them.

No Heat

Nothing is more frustrating than turning on the thermostat and the furnace failing to heat your home. Before calling in a professional, there are a few things to check. First, ensure the thermostat settings are correct and the furnace has power. If your ductwork is dirty or clogged, it can also reduce airflow, resulting in less heat production. Change the air filter if it appears dirty, and open all the vents to allow maximum airflow. If these measures don’t solve the problem, you need to call in a qualified technician to diagnose and correct the issue.

Uneven Heat Distribution

This is a common problem in large homes, where some rooms are colder than others. The cause could be blocked vents, faulty ductwork, or an overstretched or undersized furnace. Check for blocked air vents, clean or repair clogged or broken ductwork, and, if necessary, upgrade to a properly sized furnace.

Ignition Problems

If the furnace doesn’t start at all, it could be an ignition problem. Check the pilot light or the electronic igniter system to see if it is starting the furnace as required. If the pilot light is out, use the user manual to light it. For an electronic ignition system, check to ensure that all wires and connections are intact.

Clogged Filter

The air filter in your furnace helps catch debris, dust, and other air particles. Over time, the filter will become clogged, leading to less efficient heating and poor indoor air quality. Change your filter regularly to keep it clean and extend the life of your furnace. If you have pets, children, or high-traffic areas, you may need to change it monthly.

Strange Noises

If you hear strange sounds coming from your furnace, you need to investigate the cause immediately. Loud clanging, banging, or popping noises could indicate a mechanical issue, such as a loose fan belt, cracked heat exchanger, or dirty burners. Schedule a tune-up appointment with a professional to ensure that your furnace is operating safely and reliably.
