Why Routine Furnace Maintenance is Essential 

Before we dive into the specific tasks involved in maintaining your furnace, it’s important to understand why regular maintenance is crucial. Here are some of the key reasons: 

  • Energy Efficiency: A well-maintained furnace runs more efficiently, meaning it uses less energy to heat your home. This can lower your utility bills and reduce your carbon footprint. 
  • Safety: Furnaces, especially those that burn gas or oil, can pose safety risks if they’re not properly maintained. Issues like gas leaks, carbon monoxide buildup, and fire hazards can be prevented with regular checks. 
  • Consistent Heating: A furnace that’s running smoothly provides even, consistent heating throughout your home. Regular maintenance helps ensure you’re not left in the cold during winter. 

Key Components of Furnace Maintenance 

Routine maintenance typically involves a combination of professional inspections and simple tasks you can do yourself. Here’s a comprehensive look at what should be done to keep your furnace in top shape.

1. Replace or Clean the Air Filter

One of the easiest yet most important tasks in furnace maintenance is regularly replacing or cleaning the air filter. The filter keeps dust, dirt, and debris from entering the furnace and circulating through your home. Over time, a dirty filter can restrict airflow, making your furnace work harder than it should. This not only decreases efficiency but also increases wear and tear on the system. 

How often: It’s recommended to check your filter once a month and replace it every 1-3 months, depending on the type of filter and how often your furnace is running. 

Why it matters: A clean filter improves airflow, reduces energy consumption, and helps prevent breakdowns.

2. Inspect and Clean the Blower Assembly 

The blower assembly is responsible for moving the heated air from the furnace into your home. Over time, dust and debris can accumulate on the blower blades, which can reduce its efficiency and put strain on the motor. 

What to do: Inspect the blower assembly regularly and, if you notice dust buildup, clean it using a vacuum or soft brush. Be sure to turn off the power to the furnace before performing any maintenance. 

Why it matters: A clean blower assembly helps maintain consistent airflow and prevents overheating, which can lead to costly repairs.

3. Check the Thermostat Settings

Your thermostat is the control center of your heating system. Ensuring it’s functioning properly can help maintain consistent temperatures and reduce energy waste. 

What to do: If your thermostat is programmable, check that it’s set to the appropriate heating schedule for your home. If your furnace isn’t responding to the thermostat, it may need recalibration or replacement. 

Why it matters: Proper thermostat settings ensure your furnace isn’t working harder than necessary, which can save energy and extend the life of the system.

4. Inspect the Heat Exchanger

The heat exchanger is a vital component of your furnace that separates the combustion process from the air that circulates through your home. Over time, the heat exchanger can develop cracks or leaks, which can lead to dangerous carbon monoxide emissions. 

What to do: A professional should inspect the heat exchanger annually to check for cracks or signs of wear. 

Why it matters: A damaged heat exchanger can be a serious safety hazard, as it can leak carbon monoxide into your home.

5. Lubricate Moving Parts

Furnaces have several moving parts, such as the blower motor and fan, which can wear down over time if they aren’t properly lubricated. Without proper lubrication, friction can increase, causing the parts to overheat or fail prematurely. 

What to do: Check the owner’s manual for your furnace to see which parts need lubrication and what type of lubricant to use. This task is typically done during professional maintenance visits. 

Why it matters: Lubrication reduces friction and helps prevent damage to moving parts, extending the life of your furnace.

6. Test Safety Controls

Furnaces have built-in safety controls that prevent dangerous situations, such as overheating. These controls need to be tested regularly to ensure they’re functioning properly. 

What to do: During a professional maintenance visit, your technician will test these safety controls, including the high-limit switch, which prevents the furnace from overheating. 

Why it matters: Properly functioning safety controls help protect your home from fire hazards and gas leaks.

7. Check and Clean the Burners

Over time, the burners in a gas furnace can become clogged with dirt and debris, which can affect combustion and reduce efficiency. Poor combustion can also lead to an increase in carbon monoxide production. 

What to do: Have a professional inspect and clean the burners annually to ensure they’re operating efficiently. 

Why it matters: Clean burners help ensure efficient combustion and reduce the risk of dangerous emissions.

8. Inspect the Flame Sensor

The flame sensor is a safety device that ensures the furnace only runs when there is a flame to ignite the gas. If the flame sensor becomes dirty or malfunctions, it can cause the furnace to shut down. 

What to do: A professional should inspect and clean the flame sensor during an annual maintenance visit. 

Why it matters: A properly functioning flame sensor helps prevent dangerous gas buildup and ensures your furnace operates safely.

9. Inspect and Clean the Vents and Ducts

Your furnace works in conjunction with your home’s ventilation system to distribute warm air throughout your living spaces. Dust, debris, or even mold can accumulate in your ductwork and vents, reducing airflow and affecting the quality of air in your home. 

What to do: Regularly check your vents to ensure they aren’t blocked by furniture or dust buildup. Have your ducts professionally cleaned every few years, or more frequently if you notice dust or airflow issues. 

Why it matters: Clean vents and ducts improve air quality and ensure your furnace isn’t working harder than it needs to in order to heat your home.

10. Check for Leaks or Blockages in the Flue Pipe

The flue pipe is responsible for venting the gases produced during combustion out of your home. If the flue becomes blocked or leaks, dangerous gases can accumulate in your living space. 

What to do: Have a professional inspect the flue pipe during an annual maintenance visit to check for leaks, corrosion, or blockages. 

Why it matters: Ensuring the flue pipe is functioning properly is critical for safely venting combustion gases and preventing carbon monoxide poisoning. 

Professional vs. DIY Furnace Maintenance 

While there are some maintenance tasks you can easily do yourself, such as changing the air filter or checking the thermostat, many of the more involved tasks—like inspecting the heat exchanger or cleaning the burners—should be handled by a professional.  

Most furnace manufacturers recommend an annual inspection and tune-up by a licensed HVAC technician to ensure the system is operating safely and efficiently.  

When to Schedule Professional Furnace Maintenance 

The best time to schedule professional furnace maintenance is in the fall, before you start using your furnace regularly. This allows your technician to catch any issues early, ensuring your furnace is ready for the colder months ahead.

Is It Worth It to Repair a 20-Year-Old Furnace?

ongoing Furnace Repair in Seattle

A furnace that’s been working for two decades might still provide warmth on cold days, but is it truly living up to its potential? Homeowners often face this dilemma: Should they go for furnace repair in Seattle or invest in a newer one?  

With rising energy costs and innovations in heating technology, it’s worth taking a closer look at how an aging furnace compares to modern alternatives.

Deciding Whether to Repair or Replace Your Furnace? Consider These Key Factors 

Performance Over Time 

Furnaces, like most household appliances, have a finite lifespan. Most furnaces are built to last 15 to 20 years with regular maintenance. So, if your furnace has hit the 20-year mark, it may still be operational, but the question is, how well is it functioning? Over time, furnaces lose efficiency.  

A 20-year-old furnace likely doesn’t heat as evenly or efficiently as a newer model. You may have noticed rooms that aren’t as warm as they used to be or have higher energy bills than in previous winters. While repairs might get the unit working for another season, the declining efficiency may make those repairs less cost-effective. 

Repair Costs: Worth It or Not? 

At this age, repairs are often more frequent and expensive. Older furnaces tend to need parts that may not be readily available or are costly due to the system’s age. A furnace that needs constant fixing might just be showing that it’s ready to retire.  

It’s important to weigh the cost of each repair. Costs can quickly add up if you’re paying for repairs every few months. A general rule is that if the repair costs 50% or more of the price of a new furnace, replacement may be the better option. 

Energy Efficiency Matters 

Energy efficiency is one of the main reasons why homeowners decide to replace rather than repair an old furnace. Furnaces from 20 years ago were typically less efficient than the modern systems available today.  

A modern furnace can have an Annual Fuel Utilization Efficiency (AFUE) rating of up to 98%, which means nearly all the fuel it consumes is converted into heat. By comparison, a 20-year-old furnace might have an AFUE rating as low as 60% to 70%. This means you’re paying for heat that’s simply escaping rather than warming your home.  

If your furnace has you paying high energy bills even though it’s technically working, you may be better off investing in a newer, more efficient model. 

Modern Technology and Features 

Modern furnaces come with advanced features that enhance both performance and comfort, including: 

  • Variable-speed Blowers: Automatically adjust airflow to maintain consistent temperature throughout the home. 
  • Smart Home Compatibility: Control your furnace remotely using your phone or other smart devices. 
  • Enhanced Comfort: Newer models provide more even heating and better control over temperature variations. 
  • Energy Efficiency Upgrades: Modern units are designed to use less fuel while delivering more heat, leading to lower energy bills. 

A 20-year-old furnace won’t have these modern conveniences, and repairs can’t upgrade it to current standards. If comfort, convenience, and control are important to you, replacing the furnace may be a better long-term investment. 

Environmental Impact 

If reducing your carbon footprint is a priority, then a 20-year-old furnace is probably not doing you any favors. Older systems typically use more energy, contributing to higher emissions and a larger environmental impact.  

Newer furnaces offer better efficiency and have features designed to minimize their impact on the environment. A newer furnace can use less fuel to provide the same level of comfort, which means fewer greenhouse gases are emitted. Replacing an old furnace with a more environmentally friendly model will reduce energy consumption and the associated environmental impact.

Compliance with Local Regulations 

Along with energy savings, modern furnaces often meet stricter environmental regulations. Many cities, including Seattle, are adopting greener building standards, encouraging the use of energy-efficient systems that reduce carbon emissions.  

Upgrading your furnace might lower your environmental impact and ensure your home meets current or future regulations. This can add value to your home, as more buyers seek energy-efficient properties. 

Potential Safety Concerns 

Safety should be a top priority when deciding whether to repair or replace a 20-year-old furnace. Over time, furnaces can develop serious issues, such as: 

  • Worn or Damaged Components: Internal parts can degrade, increasing the risk of failure. 
  • Cracks in the Heat Exchanger: This issue can lead to dangerous carbon monoxide leaks. 
  • Ventilation Problems: Faulty ventilation can result in poor air quality and increased safety hazards. 
  • Signs of Trouble: Rust, strange smells, or unexplained illnesses may indicate serious issues that a simple repair might not fully resolve. 

If any of these warning signs are present, contacting a reliable technician to replace your furnace could be the safer option. 

Warranties and Manufacturer Support 

A furnace that’s 20 years old is long out of warranty, meaning any repairs or replacements of parts come out of pocket. New furnaces, on the other hand, come with warranties that can last up to 10 years or more, providing peace of mind and saving you money on future repairs.  

Additionally, manufacturer support for older models can be limited, as companies phase out parts for older systems. Without warranty coverage or easy access to parts, repairs become costly and more difficult. 

Comfort and Peace of Mind 

Think about the overall comfort and peace of mind that come with a furnace you can rely on. A 20-year-old system might keep you warm, but it likely won’t offer the consistent heat, quiet operation, or ease of control that modern systems provide.  

There’s also the stress of never knowing when it might fail, especially during the colder months when reliable heat is essential. While furnace repairs can keep it running, they won’t restore it to its former glory or bring it up to the standards of a new system.  

Replacing your furnace can offer long-term comfort and the security of knowing your home will stay warm through the winter without surprise breakdowns. 

Financial Considerations 

One of the biggest concerns homeowners have when faced with replacing their furnace is the upfront cost. While a new furnace is a significant investment, there are financial incentives that can make the transition easier.  

Many utility companies offer rebates or incentives for upgrading to energy-efficient systems, and newer models can save you money on energy bills each month. Additionally, financing options are often available, allowing you to spread out the cost of a new furnace over time. 

Final Thoughts: Repair or Replace? 

Ultimately, whether you should repair or replace your 20-year-old furnace depends on your specific situation. If it’s still relatively efficient, only requires minor repairs, and you’re happy with its performance, it may be worth repairing for a few more years.  

However, replacement is likely the smarter choice if you’re facing frequent breakdowns, high energy bills, and increasing repair costs. Modern furnaces offer significant advantages in terms of efficiency, comfort, and safety. While the initial cost may be higher, the long-term savings and peace of mind can more than make up for it.
