5 Signs Your Furnace Needs Repair


When your furnace needs repair, it’s time to schedule repair services. However, it can take a lot of work to spot problems in the early stages.

To help you out, we’ve compiled a list of 5 common signs that your furnace needs to be repaired. If you spot any of them, it’s best to call a professional immediately!

Your Furnace is Making Strange Noises

You should contact a professional immediately when your furnace makes a clicking noise. It is a sign that furnace repair near me is necessary to fix the heat exchanger.

Problems with your furnace’s fan motor or electrical components can also cause clicking sounds. It could signal that the fan motor or the faulty electrical part is about to die.

Furnaces are designed to be quiet, so they shouldn’t make much noise.

If your furnace makes a popping sound during its cycle, it usually means the ducts are expanding and contracting because of the changing temperatures in your home.

Popping sounds can indicate that your gas burners are dirty, which can cause an accumulation of gas in your system and result in a crack in your heat exchanger. You should immediately turn off your unit and get a technician to inspect it.

Your Furnace is Short-Cycling

Your furnace is designed to work tirelessly during the winter, generating heated air to keep your home cozy. But running on and off too often can strain the system unnecessarily and lead to problems.

An air filter soiled or blocked up is one of the most frequent reasons for short cycling. Replace it as soon as you see the problem to stop your furnace from starting and stopping.

Another common cause of short cycling is a heating system that’s too big for the space in your home. Oversized methods have too much power to heat your entire home, which can result in premature shutdowns.

Your Furnace is Burning Blue Flames

If your furnace is burning blue flames, this is a sign that it is operating safely and efficiently. The flame color indicates the amount of oxygen your furnace receives and how effective it is in burning fuel.

If the flame is yellow or orange, this could indicate that your furnace isn’t getting enough air to burn its fuel correctly. Inefficient combustion can lead to wasting energy, increasing utility bills, and releasing poisonous carbon monoxide into the home.

Keeping your furnace in good working condition can save you money, help ensure the safety of your home and keep your family healthy year-round. It’s also essential to recognize when your system needs repair and find reliable service near you.

Your Furnace is Using More Fuel

When your furnace uses more fuel than it should, it can lead to higher energy bills. While rising fuel prices can cause this, it’s also a sign that your furnace is starting to age and lose efficiency.

It’s best to get your furnace inspected by an HVAC expert to determine whether it needs repair or a replacement.

The size of your furnace isn’t the only factor in fuel consumption; it’s also how well-maintained and clean it is. Older oil-burning furnaces use much more fuel than newer models.

A well-oiled furnace is more likely to run smoothly and efficiently, so occasionally, apply a light coat of machine oil on the gas nozzles. It will help the burners to operate as intended and cut down on potential problems in the future.

Your Furnace is Taking Longer to Heat Up

If your furnace takes a long time to heat your home, you may need to repair it. Poor airflow or ductwork issues are only two potential causes of this frequent furnace issue.

Generally, your furnace should be ready to warm up your home within a few minutes of turning it on. However, if it takes more than that, there could be an issue with the fan switch.

Another common culprit is a worn or frayed blower belt, which is the component that helps the system run smoothly. These belts can make a high-pitched, loud squeal when they become frayed or slip, and it’s best to have them replaced by a professional.
