Importance of regular furnace inspection

Regular furnace inspections ensure your heating system operates safely, efficiently, and reliably. Here are some key reasons why regular furnace inspections are important:


Furnaces can pose serious safety risks if they are not properly maintained. Carbon monoxide leaks, electrical issues, gas leaks, and other hazards can risk your family’s health and safety. Regular inspections can identify and address these issues before they become dangerous.

Energy efficiency

A well-maintained furnace operates more efficiently, saving you money on your energy bills. Inspections can help identify problems with your furnace’s components, such as dirty filters or clogged ducts, which can reduce its efficiency.

Longer lifespan

Regular maintenance can do wonders for your furnace’s longevity. Identifying and repairing minor problems early can prevent larger, more expensive issues from developing down the road.

Improved indoor air quality

A dirty or poorly maintained furnace can negatively affect indoor air quality, which can cause respiratory problems, allergies, and other health issues. Regular inspections ensure that your furnace is clean and functioning properly, which can help improve your indoor air quality.

Step-by-step guide on how to inspect your furnace

Inspecting your furnace can seem challenging, but it can be done quickly and efficiently with the right guidance. Here is a detailed step-by-step guide to help you inspect your furnace.

Turn off the power

Before beginning any inspection or maintenance, turn off the power supply to your furnace. It can be done by turning off the switch on the furnace itself or by turning off the breaker in your electrical panel that controls the furnace.

Check the air filter

Your furnace’s air filter should be checked and replaced on a regular basis. Locate the air filter and remove it from its housing. Inspect the filter to see if it is dirty or clogged with dust and debris. If it is, replace it with a new one.

Inspect the blower motor

The circulation of air throughout your home is the responsibility of the blower motor. Check the blower motor and fan blades for any damage signs, such as cracks or damage. If it is necessary to replace the blower motor, it is best to hire an HVAC professional to get the job done.

Check the burner

The burner is where the fuel is ignited to heat the indoor air. Inspect the burner and look for signs of corrosion, rust, or other damage. If you notice any issues, contact a professional.

Look for leaks

Inspect the furnace and its connections for signs of gas leaks, such as hissing sounds, smells of gas, or visible cracks or damage to the connections. If you suspect a gas leak, immediately turn off the furnace and contact a licensed professional.

Check the exhaust vent

The exhaust vent removes the byproducts of combustion from your furnace. Inspect the exhaust vent and look for signs of damage or blockages, such as debris or bird nests. If you detect any problem, it is best to contact a professional technician.

Turn the power back on

After completing your inspection, turn the power supply back on to the furnace. If you notice any issues during the inspection, contact a licensed HVAC professional to address them.

Signs that you need a professional furnace inspection

Following are the signs that indicate that you need a professional furnace inspection:

Unusual noises

If you hear any strange noises, such as banging, rattling, or squeaking, it may be an indication of a problem with your furnace. These noises could indicate issues such as loose components or a malfunctioning blower.

Frequent cycling 

Frequent cycling is a common issue with furnaces, caused by factors such as a dirty air filter, malfunctioning thermostat, or faulty flame sensor. Frequent cycling can lead to increased energy consumption, decreased efficiency, and shortened lifespan of the furnace. It is essential to have a professional technician diagnose and fix the issue to ensure the proper functioning of the furnace.

Other causes

Here are some other signs that you need to call in an expert as soon as possible.

  • If your electricity bills have increased significantly and you haven’t changed your heating habits, it could indicate that your furnace is not working correctly.
  • If you observe that the air in your home is dusty or has a strange smell, it could be a sign of an issue with your furnace.
  • If some zones in your home are colder than others, it could be a clear sign that your furnace is not distributing heat evenly.

You shouldn’t take these indications for granted and call in an HVAC specialist at the earliest.
