Signs a Furnace isn't Working Properly

Homeowners should always know how old their furnace is, as older furnaces require close attention.

Furnaces are complex machines, so when they experience issues, not all homeowners are aware. However, malfunctioning furnaces often cause the heating bill to increase significantly, so homeowners should be familiar with the most common signs of furnace issues to have them repaired or replaced as soon as possible. Consider the following signs, as well as tips to maintain a furnace to avoid problems entirely.

Strange noises and odors

Sometimes, strange noises are nothing more than the house expanding and contracting as it heats and cools; however, odd noises can also result from an underlying problem. Contacting a professional to assess the problem if odd noises arise is best. Similarly, unusual odors can be a sign an animal has gained access to the furnace or that a flammable material is nearby. Do not wait until it's too late; contact a professional as soon as possible.

An old furnace

Homeowners should always know how old their furnace is, as older furnaces require close attention. Generally, furnaces older than ten years are more susceptible to problems. While some furnaces last more than twenty years and others only eight, the older the furnace, the more critical it is to watch for warning signs, as older furnaces are more susceptible to repairs and eventual replacement.

Broken thermostat

If a furnace clicks on and off frequently, or if the house is never warm, no matter how high the thermostat is set, there is likely an issue with the thermostat. For best results, contact a professional to examine and diagnose the thermostat, as there could be many causes of this issue.

A yellow flame

The flame on the furnace should be stable, clean, blue, and pure. A yellow or orange flame is a furnace warning sign of dirt in the burner and the furnace isn't creating the appropriate mix of gas and oxygen. This is a severe furnace warning sign. Call a professional before the yellow flame turns into a gas leak or something worse.

There are ways to help avoid these problems entirely. Homeowners should take several steps to ensure their furnaces are well-maintained and in working order.

Schedule a furnace inspection every winter

Before the winter season hits, schedule an inspection. This way, any repairs or replacements can be done before the cold months arrive. When it comes to winter furnace maintenance, it's always better to be prepared. Scheduling an inspection at the start of fall can help prevent unexpected repairs and breakdowns when the furnace is most needed. Furthermore, regular inspections keep the furnace running smoother and lasting longer.

Replace furnace filters regularly

A clogged furnace filter can lead to undesirable effects—the furnace might not work optimally. A clogged filter also makes the furnace work harder, causing it to overheat and need repairs. Ensure the furnace filters are fresh and clean before the winter season starts, as replacing a filter is significantly less expensive than completing a more intricate furnace repair.

Check for obstructions

Be sure nothing is obstructing the ducts or vents. Something as simple as a sofa blocking a vent can impede the furnace system, causing it to work less effectively or even break down. An HVAC system is more efficient when airflow is not blocked, and air can circulate back freely. This is an easy and effective way to ensure the furnace system operates efficiently.
