What Our AC Maintenance Service Entails

Effective air conditioning maintenance goes far beyond a simple filter change. It involves a deep, technical inspection of the system's mechanical and electrical components to ensure everything functions in unison. When a system operates with worn-out parts or dirty components, the thermodynamic process of heat exchange is hindered, forcing the compressor to draw more amperage. Our comprehensive tune-up covers the critical areas that dictate the health of your cooling infrastructure.

Condenser and Evaporator Coil Cleaning

The coils are where heat transfer occurs. Over time, the outdoor condenser coil acts as a magnet for dirt, grass clippings, and pollen, while the indoor evaporator coil can accumulate dust that bypasses the filter.

• We chemically clean the condenser coils to remove baked-on debris that insulates the coil and traps heat.
• We inspect the evaporator coil for biological growth or dust impaction that restricts airflow.
• Clean coils ensure the refrigerant can effectively absorb and release heat, preventing the system from overheating.

Refrigerant Level and Pressure Checks

An air conditioner requires a precise charge of refrigerant to cool your home efficiently. Too little refrigerant suggests a leak, while too much can damage the compressor.

• Technicians measure superheat and subcooling levels to verify the charge is exact according to manufacturer specifications.
• We inspect refrigerant lines for physical damage or insulation rot that could lead to energy loss.
• Proper refrigerant levels prevent the evaporator coil from freezing up during humid days.

Electrical Component Inspection

Vibration during operation can loosen electrical connections, creating resistance and heat that can melt wires or destroy motors.

• We tighten all electrical connections and measure voltage and amperage on motors.
• We inspect the capacitor, a common failure point, to ensure it holds the correct charge to start the compressor and fan motors.
• We check the contactor for pitting or burning, which can cause the AC to stick "on" or fail to start altogether.

Drainage and Condensate System

In a humid climate, your AC pulls gallons of water out of the air daily. This moisture must be drained away effectively.

• We flush the condensate drain line to prevent algae buildup and clogs that cause water damage to your home.
• We test the safety float switch to ensure it will shut the unit down if the drain backs up, preventing overflow.
• We inspect the drain pan for rust or cracks.

Thermostat and Airflow Calibration

Even a perfect mechanical system fails if the controls are off or airflow is restricted.

• We calibrate the thermostat to ensure it reads the indoor temperature accurately.
• We inspect the blower motor and wheel for dust buildup that reduces air movement.
• We assess the ductwork for visible leaks or collapsed sections that waste conditioned air.

Your Path to Cooler Days: Our Maintenance Process

We have refined our maintenance protocol to be thorough yet non-intrusive. Our goal is to provide a complete assessment of your system’s health without disrupting your daily routine. We follow a strict sequence of steps to ensure no component is overlooked and that your system is returned to you in better condition than we found it.

• Arrival and System Assessment: The process begins with a certified technician arriving at your property fully equipped with diagnostic tools. We start by discussing any specific concerns you have noticed, such as hot spots in certain rooms or unusual sounds. We then perform a test run of the system to establish a baseline of current performance.
• Safety and Shutdown: To safely access the internal components, we disconnect power to the unit. This allows us to open the cabinet panels and access high-voltage areas without risk. During this stage, we also inspect the area surrounding the outdoor unit to ensure there is adequate clearance for airflow.
• Deep Clean and Tune-Up: This is the core of the service. We proceed through our technical checklist, cleaning coils, lubricating moving parts like fan bearings, and tightening electrical contacts. We replace the air filter if a replacement is available and needed. We focus heavily on the outdoor unit, removing debris that has accumulated inside the chassis over the fall and winter months.
• System Reactivation and Testing: Once the mechanical and cleaning work is done, we restore power and run the system through a full cooling cycle. We monitor the temperature drop (the difference in temperature between the air going in and the air coming out) to verify the system is cooling effectively. This is when we take our final pressure readings.
• Reporting and Recommendations: Finally, we walk you through our findings. We provide a clear, written report of what was done and highlight any parts that are showing signs of wear. If a component is on the verge of failure, we present the options for proactive repair so you are not caught off guard by a breakdown later in the summer.

Deciding Between AC Repair and Replacement

During a maintenance visit, or when facing a sudden breakdown, homeowners often face the difficult choice of whether to invest in repairs or replace the system entirely. Making this decision requires a logical evaluation of the unit’s age, the cost of repairs, and its current efficiency levels. Carter Heating and Cooling helps you navigate this financial decision with transparent data.

The Age of the System

Most air conditioning systems have a lifespan of 10 to 15 years.

• If your unit is under 10 years old and has been well-maintained, repair is usually the best option.
• If the unit is over 15 years old, parts may be obsolete, and the technology is likely inefficient compared to modern standards.
• Systems in the 10-15 year "gray zone" require a closer look at repair frequency.

The 50% Rule

A general guideline in the HVAC industry is the 50% rule.

• If the cost of the necessary repair is 50% or more of the cost of a new system, replacement is the smarter financial move.
• Even if the repair is less than 50%, you must consider if this repair will be the last one, or if it is just the start of a series of failures.

Frequency of Breakdowns

A reliable system should not require repairs every season.

• If you find yourself calling for service multiple times a year, the cumulative cost of these visits often outweighs the monthly payment on a new, warranted system.
• Frequent breakdowns also indicate that the compressor or other major components are nearing the end of their life.

Efficiency and Refrigerant Type

Older units often use R-22 Freon, which has been phased out and is exponentially expensive to replenish.

• If your system leaks R-22, replacement is almost always the only viable option due to the cost of the refrigerant.
• Newer systems with higher SEER2 ratings can lower energy bills by 20% to 40%, providing a return on investment that offsets the installation cost over time.

Local Climate Considerations for Optimal AC Performance

The climate in Lewisburg, KY, falls into the humid subtropical category, which presents unique challenges for air conditioning equipment. Our weather patterns dictate that an AC unit must do more than just lower the temperature; it must also act as a powerful dehumidifier.

Combating High Humidity

In our region, the "latent load" (humidity) is often as high as the "sensible load" (heat).

• If an AC is short-cycling (turning on and off too quickly), it cools the air but fails to remove moisture. This leaves your home feeling clammy and can promote mold growth.
• Proper maintenance ensures the blower speed and refrigerant charge are calibrated to maximize moisture removal, keeping indoor humidity levels between 40% and 50%.
• We check condensate drains rigorously because the high volume of water removal in our climate leads to faster algae growth in the lines.

Seasonal Temperature Swings

We experience distinct seasons, meaning your AC sits idle for months before being thrust into maximum capacity operation.

• During the dormant winter months, outdoor units can become homes for rodents or accumulate heavy layers of wet leaves and debris.
• Spring pollen is particularly heavy in this area. Pollen that gets past the filter can coat the evaporator coil, creating a layer of insulation that destroys efficiency before summer even begins.
• Our maintenance schedule is designed to address these seasonal transitions, clearing out winter debris and preparing the system for the extreme heat of July and August.

Local Utility and Infrastructure

The electrical grid and local regulations also play a role in how we maintain systems.

1. We ensure all electrical components are within tolerance to handle minor voltage fluctuations from the grid during peak usage times.
2. We verify that your system complies with local codes regarding disconnect boxes and service clearance, ensuring your home remains safe and compliant.
