Furnace Not Heating Properly? Here’s What We Do

When a furnace acts up, it is often due to a lack of routine care rather than a catastrophic failure of a major component. Dirt accumulation, electrical loose connections, and wear on moving parts can all contribute to a system that cycles on and off too frequently or fails to ignite altogether. In Smiths Grove, where winter nights can be unforgiving, you need a system that operates at peak efficiency.

We approach furnace maintenance as a preventative science. Rather than simply changing a filter and leaving, we perform a deep dive into the mechanical and electrical integrity of your unit. This approach ensures that we are not just fixing a symptom, but addressing the root cause of inefficiency. Whether you have a gas furnace, an electric unit, or a heat pump system, the objective remains the same: safe, consistent, and affordable heat.

We focus on safety first. Gas furnaces, in particular, carry the risk of carbon monoxide leaks if heat exchangers crack or venting systems become obstructed. Our technicians use calibrated tools to test for gas leaks and verify that combustion byproducts are venting correctly outside your home. We also inspect the electrical draw of your blower motor to ensure it isn't overheating, which is a common cause of premature system failure.

Our Furnace Maintenance Services – Scope and Immediate Benefits

A professional tune-up is far more extensive than a standard visual inspection. When you book a service with us, you are investing in a rigorous checklist of tasks designed to restore your heating unit to factory specifications. This comprehensive scope of work ensures that every component, from the thermostat to the burner assembly, functions in harmony.

• Heat Exchanger Inspection: We examine the heat exchanger for cracks, corrosion, or separation. This is the most critical safety step, as a compromised exchanger can leak dangerous exhaust gases into your living space.
• Burner Cleaning and Adjustment: Dirty burners result in improper combustion, which wastes fuel and creates soot. We clean the burner assembly to ensure a clean, blue flame for maximum heat transfer.
• Blower Motor and Belt Check: We check the amperage and voltage of the blower motor for proper operation. If your system uses a belt, we inspect it for cracks and adjust the tension to prevent slippage.
• Safety Switch Testing: Modern furnaces have multiple safety interlocks, such as the limit switch and flame sensor. We test these to ensure the furnace shuts down automatically if an unsafe condition is detected.
• Electrical Connection Tightening: Vibrations can loosen electrical wires over time. We tighten all connections to prevent arcing, shorts, and component failure.
• Thermostat Calibration: We verify that your thermostat is reading the room temperature accurately and communicating correctly with the furnace control board.
• Airflow and Filter Analysis: We inspect the ductwork connections at the unit for leaks and replace or clean standard filters to ensure unrestricted airflow, which is vital for preventing overheating.

The immediate benefits of this detailed service are noticeable. You will likely experience more even temperatures throughout your home, eliminating cold spots. Furthermore, a clean system runs quieter and cycles less frequently, reducing the daily wear on the equipment.

Step-by-Step Furnace Maintenance Process

Understanding what happens during a maintenance visit helps homeowners see the value in professional service. We follow a logical, step-by-step protocol to ensure nothing is missed. This systematic approach allows us to provide a consistent high standard of service for every home in the region — read our HVAC FAQs.

System Start-Up and Assessment:

The technician begins by operating the furnace to listen for unusual noises like banging, rattling, or squealing. We monitor the startup cycle to see if the ignition is smooth or delayed. This initial assessment gives us clues about where to focus our attention.

Shut Down and Deep Cleaning:

Once the initial test is done, we shut off power and gas to the unit. We proceed to remove debris from the cabinet and clean the blower wheel. Dust buildup on the blower wheel acts as insulation, causing the motor to run hotter and reducing air volume. We also gently clean the flame sensor, as oxidation here can cause the furnace to shut down explicitly as a false safety measure.

Component Inspection and Lubrication:

We examine the flue pipe for rust or blockage. We lubricate all moving parts that are not permanently sealed, such as older fan motor bearings and induced draft motor bearings. Reducing friction is key to extending the life of these motors.

Ignition and Combustion Analysis:

We restart the system and measure the gas pressure at the manifold. Incorrect gas pressure can lead to overheating or insufficient heat. We adjust this to the manufacturer's specified water column inches. We then perform a combustion analysis to measure the efficiency of the burn and the composition of the exhaust gases.

Final Operation Test:

Finally, we let the system run for a sustained period to measure the "temperature rise"—the difference in temperature between the air entering the furnace and the air leaving it. This number must fall within the range specified on the unit’s rating plate to prevent damage to the heat exchanger.

Deciding Between Furnace Repair and Replacement: What You Need to Know

There comes a point in the lifespan of every heating system where maintenance and minor repairs are no longer cost-effective. Determining when to stop repairing and invest in a new unit is a major decision. We help homeowners navigate this choice using data and clear metrics rather than guesswork.

• The Age of the System: The average lifespan of a well-maintained furnace is between 15 and 20 years. If your unit is approaching or exceeding 15 years and requires a significant repair, replacement is often the smarter financial move. New units offer higher efficiency ratings (AFUE), which can lower monthly utility bills immediately.
• The Cost of Repair vs. Value: We often recommend the "50% Rule." If the cost of the repair is 50% or more of the cost of a new system, you should replace it. Similarly, if the repair cost multiplied by the age of the unit exceeds $5,000, replacement is usually justified.
• Frequency of Breakdowns: If you have required repairs more than twice in the last two years, your system is becoming unreliable. The cumulative cost of service calls and parts often outweighs the monthly payments on a new, warranted system.
• Safety Concerns: If a heat exchanger is cracked, repair is rarely a viable option due to the severe safety risk of carbon monoxide. In almost all cases involving a cracked heat exchanger, full system replacement is the only responsible recommendation.
• Rising Energy Bills: If your heating costs have increased significantly despite usage remaining the same, your furnace’s efficiency has degraded. Older furnaces may operate at 60-70% efficiency, while modern units can reach up to 98%. The savings in fuel can offset the cost of installation over time.

Carter Heating and Cooling technicians provide transparent assessments. If your system still has life left, we will tell you. If it is a money pit, we will show you the numbers so you can make an educated choice.

Understanding Smiths Grove Climate Impact on Your Furnace

The climate in Smiths Grove presents specific challenges that dictate how we approach furnace maintenance. While we enjoy four distinct seasons, the winter months can bring sustained temperatures below freezing, coupled with significant precipitation. This environment impacts HVAC equipment in unique ways that generic maintenance checklists might miss.

• Temperature Fluctuations: We often see swings from 50 degrees to 20 degrees within 24 hours. This rapid change forces the furnace to work hard intermittently. This thermal expansion and contraction can loosen fittings and stress the heat exchanger metal. Our inspections pay close attention to stress fractures caused by these cycles.
• High Humidity and Precipitation: Kentucky is known for its humidity, even in cooler months, and annual precipitation around 50 inches. High moisture levels in basements or crawl spaces where furnaces are often located can lead to premature rusting of the cabinet and corrosion of electrical contacts. We inspect for signs of moisture damage and check condensate drains on high-efficiency condensing furnaces to ensure they are not blocked or frozen.
• The "Shoulder Season" Strain: In the transition from autumn to winter, homeowners often switch between heating and cooling or turn the system on and off frequently. This short-cycling can wear out the igniter and the capacitor. We check these startup components specifically because they take the brunt of the workload during variable weather.

Local utility infrastructure also plays a role. We ensure your equipment is compatible with local gas pressure delivery and electrical voltage stability. Furthermore, if you are considering an upgrade, we are familiar with local code requirements for venting and gas piping in Smiths Grove, ensuring that any work performed meets all regulatory standards for safety and insurance compliance.
