What Our Comprehensive Furnace Maintenance Service Includes

Effective furnace maintenance goes beyond a simple filter change. It requires a deep technical analysis of your heating unit’s internal components to ensure they are operating within manufacturer specifications. Our service is designed to cover every critical aspect of your system, ensuring that safety mechanisms are functional and that the unit is burning fuel efficiently.

Critical Component Inspection and Cleaning

The core of our maintenance visit involves the inspection of the heat exchanger. This component is responsible for separating combustion gases from the air circulating in your home. A cracked heat exchanger can leak carbon monoxide, posing a severe safety risk. We use specialized cameras and sensors to detect hairline cracks that are invisible to the naked eye. Additionally, we clean the burners to ensure proper ignition. Dirty burners can cause delayed ignition or "rollout," which damages the furnace and wastes fuel.

Electrical and Safety Control Testing

Modern furnaces rely heavily on complex electrical systems. We examine the wiring for signs of corrosion or loose connections that could lead to intermittent failures. We also test the flame sensor, a safety device that shuts off the gas if a flame is not detected. If this sensor is dirty or oxidized, your furnace will shut down repeatedly as a safety precaution. Our technicians clean and calibrate this sensor to prevent nuisance tripping. Furthermore, we test the high-limit switch, which prevents the furnace from overheating and causing fire hazards.

Airflow and Blower Motor Optimization

Proper airflow is essential for the longevity of your system. Restricted airflow causes the heat exchanger to overheat, shortening the lifespan of the unit. We inspect the blower motor and wheel for dust buildup, which can reduce efficiency by up to 20%. We check the capacitor, which provides the torque needed to start the motor. A weak capacitor is a common cause of blower motor failure. We also inspect the belt tension (on older units) and lubricate moving parts to reduce friction and noise.

Thermostat and System Calibration

Your thermostat acts as the brain of your HVAC system. If it is calibrated incorrectly, your furnace may run longer than necessary or cycle too frequently (short-cycling), leading to excessive wear and tear. We verify that the thermostat reads the room temperature accurately and communicates effectively with the furnace control board. This ensures that your home remains at the desired temperature without wasting energy.

The Steps of Our Furnace Maintenance Process

We utilize a structured, repeatable process to ensure no detail is overlooked during your service appointment. This systematic approach allows us to provide consistent, high-quality results for every homeowner in Franklin.

• Upon arrival, the technician performs an initial operational assessment. We turn the thermostat up to call for heat and observe the startup sequence. This allows us to listen for abnormal sounds such as rattling, banging, or squealing, which often indicate loose parts or bearing failure.
• Next, we shut off power to the unit and begin the internal cleaning process. We remove the blower assembly to clean the fan blades and the housing. Dust accumulation here acts as an insulator on the motor and creates drag on the fan, forcing the system to work harder.
• Following the cleaning, we focus on the ignition system. For gas furnaces, we remove and clean the flame sensor and inspect the hot surface ignitor for cracks or white spots, which indicate imminent failure. We then check the gas pressure at the manifold to ensure the fuel-to-air ratio is correct. Incorrect pressure can lead to soot buildup or inefficient combustion.
• After the mechanical work is complete, we check the flue pipe and ventilation. We ensure there are no blockages (such as bird nests or debris) and that the drafting is working correctly to vent dangerous gases outside the home.
• Finally, we restart the system and perform a combustion analysis. This test measures the efficiency of the burn and checks for carbon monoxide presence in the supply air. We document all findings and provide you with a clear report on the current health of your system.

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

At a certain point, continuing to repair an aging furnace becomes less economical than investing in a modern, high-efficiency unit. Understanding when to pivot from maintenance to replacement is key to managing your long-term home operational costs. Carter Heating and Cooling helps you navigate this decision with data, not pressure.

The Age and Reliability Factor

The average lifespan of a well-maintained furnace is between 15 and 20 years. If your unit is approaching or has exceeded the 15-year mark, major components like the heat exchanger or blower motor are statistically more likely to fail. Even if the unit is running, it may have lost significant efficiency. If you find yourself calling for repairs more than once a heating season, the cumulative cost of these service calls often outweighs the monthly financing cost of a new system.

The 50% Investment Rule

A general guideline used in the HVAC industry is the 50% rule. If the cost of a necessary repair approaches 50% of the value of a new system, replacement is the financially sound choice. For example, replacing a cracked heat exchanger or a failed compressor in an old unit is a major expense. Putting that money toward a new unit with a 10-year warranty protects your investment, whereas repairing an old unit offers no guarantee that another part won't fail next month.

Efficiency Ratings and Energy Savings

Older furnaces often operate at 60% to 70% AFUE (Annual Fuel Utilization Efficiency). This means that for every dollar you spend on gas, 30 to 40 cents is wasted up the chimney. Modern high-efficiency furnaces operate at 95% AFUE or higher. In the Franklin climate, where winters are moderately cold but heating is required for several months, upgrading from a 70% unit to a 95% unit can result in substantial savings on your monthly energy bills. These savings can effectively offset a portion of the installation cost over time.

Comfort and Noise Considerations

As furnaces age, they often struggle to distribute air evenly. You may notice cold spots in certain rooms or significant temperature fluctuations between cycles. Older units also tend to be louder, with rattling sheet metal or noisy startup cycles. New variable-speed furnaces operate more quietly and run for longer, lower-intensity cycles, providing consistent heat distribution and better humidity control throughout the home.

Understanding Franklin's HVAC Requirements and Seasonal Considerations

Operating a furnace in Franklin, KY requires attention to specific regional factors that impact system performance and longevity. The local climate is classified as humid subtropical, meaning moisture control is an issue year-round, not just in summer. During the winter, maintaining proper humidity levels is essential for comfort and protecting the home’s structure.

Addressing Winter Humidity Levels

While summers are humid, Franklin winters can be dry. However, a furnace that is not venting properly can introduce excess moisture into the home, leading to condensation on windows and potential mold growth. Conversely, older furnaces can dry out the air excessively, causing respiratory issues and static electricity. Our maintenance checks include an assessment of your humidifier (if installed) or recommendations on how to balance indoor humidity levels for the specific climate conditions in Simpson County.

Freeze Protection and Pipe Safety

With average winter lows dropping into the 20s, and occasional extreme cold snaps, a furnace failure is more than an inconvenience; it is a property risk. If a furnace fails during a freezing night, the temperature inside the home can drop rapidly, leading to frozen and burst plumbing pipes. Regular maintenance ensures that your system is prepared to handle the heaviest workloads during January and February, preventing costly water damage associated with heating failure.

Venting and Utility Safety

Local building codes and utility safety standards regarding gas lines and venting must be strictly adhered to. Blocked vents or improper drafting can be fatal due to carbon monoxide buildup. Our technicians are well-versed in the local requirements for safe venting, particularly for homes with older masonry chimneys that may require liners for modern furnace compatibility. We ensure that your system meets all safety standards required for operation in the region.
