What Does AC Maintenance Include?

As homeowners, our to-do lists often overflow with tasks and responsibilities, each vying for our attention. Amidst this juggling act, the faithful air conditioner quietly performs its duty, bringing relief from sweltering temperatures. Yet, behind the scenes, there’s a crucial task that often goes unnoticed—air conditioner maintenance.

In this comprehensive guide, Advantage Heating & Air Conditioning explains the key components of AC maintenance, shedding light on the tasks that can enhance the performance and longevity of your AC unit.

Professional AC Maintenance Check: A Step-by-Step Guide

Homeowners should schedule AC maintenance at least once a year with a professional technician, ideally in the spring, to ensure optimal performance and longevity of your cooling system. While there are DIY tasks that homeowners can handle more frequently, routine maintenance is essential for the health and performance of your air conditioning unit.

1. Comprehensive System Inspection

Professional AC maintenance begins with a thorough inspection of the entire air conditioning system. This includes the indoor and outdoor units, as well as associated components such as ductwork. The goal is to identify any visible signs of wear, tear, or damage. If concerns are found, your HVAC maintenance technician will discuss these findings with you so that a plan can be made to address any repairs needed.

2. Air Filter Examination and Replacement

The AC unit’s air filter is the first line of defense against airborne particles. Without this defense mechanism, contaminants could infiltrate the system, leading to the accumulation of dirt and debris on critical components such as the evaporator coil and condenser coil. Over time, this buildup can strain the entire system and potentially lead to malfunctions or breakdowns.

During a maintenance check, technicians examine and replace air filters if necessary. Clean air filters contribute to improved indoor air quality and prevent strain on the system.

3. Checking Electrical Connections

Electrical connections within your air conditioning system are the lifelines that ensure smooth communication and operation of various components. Any faults in these connections can not only lead to system failures but also pose significant safety hazards.

Technicians inspect each electrical connection point, from wiring to terminals and contact points to identify any signs of corrosion, wear, fraying, or loose connections that might compromise the system’s electrical integrity. Loose connections are tightened so they are secure and stable.

4. Evaluation of Evaporator Coils

Responsible for absorbing heat and facilitating the exchange of warm air for cooler temperatures, the efficiency of the evaporator coil directly influences the overall performance of your AC unit. During routine HVAC maintenance checks, skilled technicians perform a careful examination to identify any accumulated dirt or debris that might hinder the coil’s ability to absorb heat effectively. Once identified, technicians remove the buildup, ensuring the coils are pristine and unobstructed.

5. Condenser Coil Maintenance

The condenser coils, located in the outdoor AC unit, are susceptible to dirt buildup that can restrict performance and efficiency. Through a careful and thorough cleaning process, technicians remove any buildup that could impede the coil’s ability to release heat effectively. This safeguards against potential malfunctions and ensures that your entire air conditioning unit operates at its peak efficiency,

6. Refrigerant Level Check

Refrigerant serves as the lifeblood of the cooling process, absorbing and releasing heat to regulate the temperature inside your home. Detecting refrigerant leaks is crucial because low refrigerant levels can severely impact the efficiency of your heating and cooling system, leading to compromised cooling performance.

Technicians perform pressure testing and visual inspections to identify the source and extent of any leaks. Once detected, they proceed with necessary AC repairs, sealing the leaks to prevent further refrigerant loss.

7. Inspection of the Drain Line

Clogged drain lines can lead to water leaks and moisture-related issues. The inspection begins with a visual examination of the drain line for any signs of blockages or debris. This may include algae growth, mold, or accumulated dirt that can impede the flow of water. Special attention is given to potential bends or curves in the drain line where clogs are more likely to occur.

Once any visual issues are identified, the technician proceeds to clear the drain line using a wet-dry vacuum, a special cleaning solution, or compressed air to dislodge and remove any obstructions. The goal is to ensure that the drain line is free from any impediments, allowing the condensed water to flow unobstructed from your air conditioning equipment.

8. Assessment of the Thermostat

The thermostat is the control center of your cooling system. Technicians meticulously check the thermostat’s calibration, addressing any discrepancies that may have developed over time. This attention to detail guarantees that the air conditioning system responds precisely to your temperature adjustments, providing a comfortable and consistent climate within your home.

9. Lubrication of Moving Parts

Friction in moving parts can lead to increased energy consumption and system wear. Lubrication of fan motors and other moving components ensures they operate with minimal resistance to reduce strain. The result is not only enhanced energy efficiency, which translates to lower utility bills but also a prolonged lifespan for critical components and a reduced need for air conditioning repair.

10. Checking and Tightening Belts

Certain air conditioner models utilize belt drives to power the blower fans. Over time, these belts can experience wear and loosening, which can compromise the system’s performance and efficiency.

During the maintenance check, technicians inspect the condition of the belts, checking for signs of fraying, wear, or slack. If any issues are identified, they promptly tighten or replace the belts as needed.

11. Air Flow Assessment

Measuring airflow is a crucial aspect of AC maintenance. Technicians use specialized tools to assess the volume and velocity of air moving through the system. This step helps identify any restrictions or blockages that may impede proper airflow.

Once the assessment is complete, technicians may adjust airflow settings as needed. This involves calibrating dampers or other components to ensure a balanced and efficient distribution of air throughout the system.

12. Assessment of System Controls

Accurate system controls are crucial for proper operation. Air Conditioner maintenance involves a comprehensive check and calibration process, ensuring that the controls are precisely aligned with the desired settings. Any discrepancies or inaccuracies are promptly addressed, guaranteeing that the air conditioner reacts effectively to changes in temperature settings.

13. Examination of Safety Controls

Air conditioners are equipped with safety controls to mitigate potential hazards and ensure the secure operation of the system. Whether it’s a high-pressure switch preventing potential damage to the compressor or a limit switch ensuring safe operating temperatures, these safety controls are a critical aspect of the air conditioning system.

During a thorough maintenance check, technicians prioritize the inspection and testing of these safety controls. This involves a meticulous examination to verify that each safety device is functioning correctly. Technicians may simulate various scenarios or malfunctions to ensure the safety controls respond appropriately.

DIY Maintenance Tips for Homeowners

In addition to scheduling professional AC maintenance services, homeowners should take these steps to supplement the care of their air conditioning systems throughout the cooling season:

1. Regularly Cleaning Around the Outdoor Unit

Clearing debris, leaves, and vegetation around the outdoor unit helps maintain proper airflow and prevents overheating.

2. Changing Air Filters

Regularly changing air filters is a simple yet effective DIY maintenance task that improves indoor air quality and extends the life of your AC unit.

3. Monitoring System Performance

Pay attention to any unusual noises, fluctuations in cooling performance, or changes in energy bills. Promptly addressing these issues can prevent more significant problems.

4. Utilizing a Vacuum Cleaner on Air Vents

Keeping air vents clean by using a vacuum cleaner ensures unobstructed airflow, promoting efficient cooling throughout the home.
