Regular maintenance can keep your furnace running longer, but how often should you have your furnace serviced?

Many homeowners wonder if yearly maintenance is really necessary, and the answer might surprise you.

If you want to keep your furnace running for years to come and avoid major issues down the line, read on. We’ll teach you all about furnace maintenance in this guide.

Common Furnace Problems

Before we dive into when to have a furnace serviced, let’s first go over the importance of maintenance.

Is yearly furnace maintenance necessary? It’s recommended, as annual furnace maintenance can spot potentially dangerous issues early on.

For example, a gas furnace inspection could reveal a cracked heat exchanger. In a gas furnace, a cracked heat exchanger can release toxins such as:

  • Carbon dioxide
  • Nitrogen oxides
  • Carbon monoxide
  • Soot

Breathing in these toxins can lead to health problems for you and your family.

Inspections can also uncover problems like a faulty or clogged pilot light. This isn’t an issue you should try to fix yourself, which is why scheduling furnace maintenance is so important.

How Often Should You Have Your Furnace Serviced?

We often hear the question, “Should I get my gas furnace serviced every year?” In short, the answer is yes. Ideally, you would have your furnace serviced at least once a year.

To elaborate on that point, you should have your furnace serviced at least once a year to catch any problems early on and to keep your furnace in top condition.

Professional maintenance and cleaning provide many benefits, which we’ll cover next.

Other Benefits of Furnace Maintenance

An annual furnace cleaning can clean out any blockages, ensure all the parts are in working order and keep your filter clean to keep your air quality safer.
One benefit of keeping the furnace clean is that the unit won’t work as hard, and you won’t have to worry about sky-high energy bills. Yet another advantage is that regular maintenance can extend the life of your furnace.

How to Clean a Furnace

There are certain tasks homeowners can do on their own, and some are best left to the professionals.
You can use a vacuum attachment to clean off dust and look for any signs of soot. Soot can be a sign of a bigger problem requiring maintenance.
Another fairly easy task is to check the filter. Make sure it’s clean.
Parts of your system, such as the blower, need to remain balanced. Take care not to disturb the counterweights or wires, or leave this job to the pros.
Here are some parts you should inspect or parts the technician will look at during maintenance:

  • Heat exchanger
  • Venting
  • Flame sensor and ignition
  • Safety switches
  • Burners
  • Combustion blower
  • Main blower
  • Filter
  • Wiring
  • Drainage

Any parts showing damage, such as a cracked drive belt, will need replacing. This can impact how much furnace maintenance costs, but it keeps you and your family safe.

Keep Your Furnace in Top Shape

To sum it up, how often should you have your furnace serviced? It’s highly recommended that you have your furnace serviced and cleaned at least once per year for the reasons we mentioned above.
