Should You Clean a Furnace?

Regular furnace cleaning is an essential aspect of maintaining a comfortable and energy-efficient home in Arizona.

Dust and debris buildup can impede your furnace’s performance, leading to increased energy consumption and a shortened lifespan for the appliance.

Fortunately, routine cleaning helps prevent these issues. By removing contaminants, you can promote optimal efficiency and potentially lower your energy bills. Furthermore, a clean furnace contributes to better indoor air quality, benefiting the health of your entire household.

How Often Should Furnace Be Cleaned?

The cleaning schedule for your furnace depends on a few factors, but here’s a general guideline.

  • Air Filter: This is the most crucial component. Replace your air filter every 1-3 months, depending on how often you use your furnace and if you have pets. Pets can shed more fur and dander, which clogs filters faster.
  • Basic Cleaning: You can attempt a basic cleaning yourself every year This involves removing dust from accessible areas around the furnace and burner compartment. If you’re not comfortable with this task, you can always call a professional.
  • Professional Cleaning: It’s recommended to have a professional cleaning done every 1-2 years. Professionals have the expertise and tools to thoroughly clean your furnace, including the internal components and ductwork (if needed). This ensures optimal performance, efficiency, and safety.

Let’s explore the steps involved in keeping your furnace functioning at its best.

How to Clean a Furnace in 5 Steps

While attempting a DIY furnace cleaning is possible for some, professional cleaning offers a more comprehensive and safe approach for most Arizona homeowners.

Here’s a detailed look at what a professional technician typically does during a furnace cleaning service.

Step 1: System Shutdown and Safety Check

  • The technician will begin by shutting down your furnace’s electrical supply at the breaker box and the gas supply using the gas shut-off valve. This ensures complete safety during the cleaning process.

Step 2: Visual Inspection and Access Panel Removal

  • Next step involves thoroughly inspecting the furnace for any visible signs of damage, corrosion, or leaks.
  • The technician will also identify the access panels for the burner compartment, heat exchanger, and blower compartment.

Step 3: Cleaning the Burner Assembly

  • Once the access panels are removed, the technician will carefully detach the burners. Using specialized tools and a high-powered vacuum, they will meticulously clean the burners, removing dust, debris, and any built-up cobwebs.
  • The flame sensor and igniter assembly will also be inspected and cleaned if necessary.

Step 4: Heat Exchanger and Blower Cleaning

  • Next, the technician will access the heat exchanger, the heart of the furnace. Using specialized brushes and vacuums, they will thoroughly clean the internal components to remove soot, dust, and any other contaminants that may impede heat transfer.
  • The blower compartment will also be cleaned, removing dust and debris from the fan blades and housing.
  • At this stage, the technician will also inspect the blower motor for any signs of wear and tear. If necessary, they will lubricate the motor following the manufacturer’s recommendations.

Step 5: Air Filter Replacement and System Reassembly

  • An old air filter will be replaced with a new one before reassembling the furnace.
  • After meticulously cleaning all the components, the technician will carefully reassemble the furnace, ensuring all connections are secure.
  • Finally, they will perform a safety check to ensure there are no gas leaks and that the furnace ignites properly.
  • The technician will also test the airflow and overall performance of the furnace to ensure it’s operating efficiently.

Additional Services

Depending on the condition of your furnace and your specific needs, we may recommend additional services such as:

  • Flue pipe cleaning: This involves cleaning the exhaust pipe that vents combustion gases outside your home.

What happens if you don’t clean your furnace?

Here’s what can happen if you neglect to clean your furnace:

  • Costs more to run: A dirty furnace works harder, leading to higher energy bills.
  • Shorter lifespan: Dirt and grime wear down the furnace, requiring replacement sooner.
  • Poor air quality: Dust and allergens circulate throughout your home.
  • Safety risk: Built-up combustibles can increase fire risk.
  • Unpleasant odors: Dust mites and mold can cause musty smells.

Safe to say, these are all problems that can be easily avoidable with regular cleaning and furnace maintenance.

How do you know if your furnace is dirty?

Ignoring your furnace’s cleaning needs can lead to a domino effect of problems. A dirty furnace struggles to maintain consistent temperatures, resulting in higher energy bills and uneven heating throughout your home.

Reduced airflow due to clogged filters or dirty components can also be a culprit. Furthermore, strange odors, frequent on-and-off cycling, and noisy operation are all signs that your furnace might be harboring dust, debris, or even mold growth.
