According to the BLS, the average US household spends $2,335 on home maintenance per year.

When it comes to maintaining a comfortable and safe home, understanding the signs of a broken furnace is crucial. A malfunctioning furnace not only compromises your comfort but can also pose serious safety risks.

This guide highlights four key indicators that your furnace may need attention or repair.

Read on to learn more about how to deal with a broken furnace.

1. Unusual Noises

Banging noises might suggest that parts within your furnace are loose or breaking. Whistling sounds could indicate a problem with your furnace’s filters or a leak in the duct system. Grinding noises are often a sign of a more serious issue, like a problem with the furnace’s motor or blower.

If the noise is coming from the furnace itself, it could be a sign that a component needs repair or furnace replacement. If the noise is coming from the ductwork, it might be an issue with the airflow or a blockage. In either case, getting a professional to inspect your furnace as soon as possible is crucial to prevent further damage.

2. High Energy Bills

If you’ve noticed a sudden increase in your heating bills, it could be a sign that your furnace is not operating as efficiently as it should be. Regular maintenance, such as replacing or cleaning air filters and checking the thermostat settings, can help improve your furnace’s efficiency.

However, if these simple fixes don’t resolve the issue, it might be time to call in a professional. A technician can conduct a thorough inspection to identify any underlying problems that are causing your furnace to be less efficient and recommend the appropriate repairs or adjustments.

3. Inconsistent Heating

Inconsistent heating in your home, where some rooms are warmer than others, can be a frustrating experience. This issue often indicates that your furnace is not distributing air properly throughout your house.

To address this problem, start by checking for any obvious blockages in your vents and ensuring they are all open. If this doesn’t resolve the issue, the problem might be more complex, such as a malfunction in the duct system or a failing part in the furnace. 

4. Yellow Pilot Light

A healthy furnace pilot light should always burn blue. If you notice that the flame has turned yellow, it’s a serious warning sign that should not be ignored. A yellow flame can indicate the presence of carbon monoxide, a colorless, odorless, and potentially lethal gas. This situation usually arises when the furnace isn’t burning fuel completely.

If you see a yellow pilot light, it’s critical to act immediately. Turn off your furnace, open windows to ventilate your home, and call a professional to inspect your furnace.
