During the winter months, your furnace is a piece of important equipment that keeps you warm and comfortable in your house. When it has trouble providing heat, your house might become unpleasant, if not unlivable. But how can you tell if your furnace is having problems preventing it from working properly? We examine some of the symptoms of a faulty furnace to help you determine whether your furnace needs to be fixed.

1. The Furnace Isn't Turning On

As your furnace ages, you may have greater difficulty turning it on and keeping it running. If you've attempted to start it several times and it keeps resuming during the day, the device should be serviced. Replacing or repairing the problematic parts of your equipment should assist in resolving the issue. You may be tempted to solve the problem yourself, but doing so might be risky, especially if you have a natural gas or electric furnace. As a result, you should consult with a specialist.

2. Your Unit Is Blowing Cold Air

If your furnace isn't blowing warm air, you should have it inspected. Although you can wait a while to see if the problem resolves, it's good to get your furnace checked as soon as possible. This allows you to have the problem repaired before your unit requires repairs or replacement.

3. Your Unit Is Making Noises

Your furnace may make various noises, including clicking or clunking or loud beeping. These noises can be caused by various things, such as a fan belt being loose or bad motor bearings. When your unit is making noises, it could be a sign of a problem. In most cases, noises can be fixed by your furnace service technician.

4. You Are Experiencing Frequent Breakdowns

If your unit is experiencing frequent breakdowns and you're having to replace multiple parts every month, it could be time to replace your furnace. Instead of trying to replace parts or deal with the constant breakdowns, it's time to get a new furnace.

5. Your Home Heats Up or Cools Down Slowly

When your furnace isn't functioning correctly, it might not be able to warm or cool your home as quickly as it should. If your home is cooling down or heating up slowly, you might be experiencing a problem with your unit.

6. Your Unit is Too Old

A furnace has an average lifespan of roughly 15 years. Before moving into a new house, you should find out how old the furnace is. You should also inquire about any recent repairs to the unit. This will help you understand your HVAC system better. Sometimes your furnace is beyond repair, and you must replace it.


Furnaces come with a variety of issues that can cause them to malfunction. This can lead to your unit not producing the right amount of heat or to your unit making noises and having frequent breakdowns. If you notice any of these signs of a malfunctioning furnace, have a professional examine your unit. Local furnace repair companies can quickly diagnose any problems and help you resolve them quickly and affordably.
