As the vibrant colors of the Willamette Valley start to fade and the crisp autumn air signals the inevitable arrival of winter, the last thing any Salem homeowner wants to worry about is a furnace breakdown. Yet, every year, we receive emergency calls when the first true cold snap hits, wanting urgent service for systems that haven’t been maintained.

At CJ Hansen, your local HVAC experts, we want to help you avoid that mid-winter crisis. Scheduling a professional furnace tune-up this fall isn’t just about convenience; it’s a preventative measure you can take to protect your family’s comfort, safety and substantial home investment before the first sustained freeze forces your heating system into heavy-duty operation.

Why Fall is Non-Negotiable

Why should you book your maintenance in the fall? It’s simple: preparedness and availability.

When December hits and temperatures drop consistently, every HVAC company’s calendar fills instantly with emergency repairs, often for systems that failed due to a lack of maintenance. By scheduling your tune-up in the fall, you ensure that:

• Any Issues Are Fixed Before They Are Critical: If our technician finds a failing component, like a weak igniter or a cracked heat exchanger, you have time to schedule a repair or replacement without the pressure of an immediate crisis.
• You Get Priority Scheduling: You won’t be waiting days in the cold for an emergency appointment. You choose a time that works for you.
• The System is Ready to Go: You flip the switch with confidence, knowing your furnace is optimized for efficiency and safety.

Safety is the Number One Priority

Many Salem homes rely on high-efficiency gas-fueled furnaces. While they are designed for safety, they involve a combustion process. A professional tune-up includes vital safety checks that are arguably one of the most essential services we provide.

Understanding the High-Efficiency Difference: Exhaust and Sensor Safety

Inside a High-efficiency furnace, with air switches

High-efficiency furnaces operate differently from standard models, particularly in terms of exhaust. Their exhaust or vent temperatures are significantly lower, often around 90 degrees Fahrenheit. This low temperature, while not a fire hazard, can lead to unique operational problems:

• Critter and Insect Blockages: The comfortably warm exhaust pipes can attract critters and birds looking for a warm nesting spot. Any blockage will negatively impact the pressure in the exhaust pipe, which is crucial for proper, safe combustion. This can lead to improper combustion or a failure to ignite, leaving you in the cold.
• Sensor Interference: These advanced furnaces use a complex array of sensors, such as air switches, to manage safe operation. A warm environment can also attract nesting insects that may place their home or egg cocoon directly inside one of these sensors, blocking or otherwise interfering with its proper function and leading to unexpected system shutdowns.

Our technicians are specifically trained to inspect these unique high-efficiency components and vent systems to prevent these very subtle, but critical, issues.

• Heat Exchanger Inspection: This is the heart of the safety check. The heat exchanger separates the combustion gases from the air that flows into your home. Over time, extreme heat fluctuations can cause tiny, microscopic cracks. A failing heat exchanger can allow harmful combustion byproducts, including the deadly gas, Carbon Monoxide (CO), to leak into your breathable air. Our technicians use specialized tools to meticulously inspect this component for any signs of corrosion or damage, ensuring the integrity of your home’s air barrier.
• Gas and Electrical Connections: We test the gas pressure, inspect the fuel lines for leaks, and check all electrical connections and wiring. Faulty wiring can lead to potential fire hazards, while incorrect gas pressure compromises efficiency and safety. We ensure that the burner assembly is igniting and combusting fuel cleanly and safely.

Preventing the Breakdown & Inspecting Key Components

Think of your furnace as a complex machine that sits idle for half the year. When you ask it to fire up for heavy use, tiny issues can become catastrophic problems. Many HVAC professionals estimate that consistent, routine maintenance can prevent the need for costly repairs in up to 80% of cases. A tune-up allows our experienced technicians to perform a deep inspection and correction of mechanical and operational issues:

• Burner Cleaning and Adjustment: Dirt and dust can accumulate on the burners over the summer. Dirty burners lead to incomplete combustion, which wastes fuel and creates harmful soot. We clean and adjust the burners to ensure a perfect, clean flame.
• Lubricating Moving Parts: Components like the blower motor bearings require lubrication. Lack of lubrication causes friction, which increases energy consumption and leads to premature motor failure, a common and costly repair.
• Checking the Blower Assembly: The blower fan is responsible for moving heated air throughout your ductwork. We ensure the fan and its housing are clean and balanced. A dirty blower wheel can reduce airflow by up to 15%, forcing the motor to overwork.
• Testing the Flame Sensor and Pilot Light: These components ensure that gas is only flowing when it can be safely ignited. If the flame sensor is dirty, it will often cause the furnace to shut off unexpectedly (short cycling), leading to no heat.

Boosting Efficiency and Securing Financial Benefits

After we clean and calibrate your system, it will run much closer to its factory efficiency rating. Experts estimate that deferred maintenance can cost you 5-10% of your operational efficiency each year. By eliminating dirt buildup and adjusting settings, a tune-up can reduce your energy consumption by up to 30% compared to a neglected system.

Maintaining your manufacturer’s warranty is a crucial, yet often overlooked, financial safeguard. Most manufacturers require documented proof of annual professional maintenance to keep the equipment warranty valid. Skipping a tune-up could therefore void your warranty, leaving you financially responsible for the full cost of a major repair or even a complete replacement down the line.

The Importance of the Air Filter

While changing your filter is a basic homeowner task, the professional tune-up ensures you’re using the right filter and that the filter area itself is clean. A technician will check:

• The Correct MERV Rating: Is your filter too restrictive (which can harm the blower motor) or not restrictive enough (which allows debris into the system)? We ensure the filter matches your system and your indoor air quality needs.
• Overall Airflow: We check the system’s static pressure to ensure air is moving freely throughout the return and supply ducts. Poor airflow not only compromises comfort but can lead to overheating and damage to the heat exchanger.

Don’t wait until the furnace is running 24/7 to find out there’s a problem. The ideal time for maintenance is early fall, before the first freeze and before our schedule fills up with emergency calls. Trust CJ Hansen’s certified team to provide the thorough, meticulous service that guarantees your family’s safety and comfort all winter long.
