Air Conditioner Service Vs. Repair: Knowing The Difference

August 10, 2023


When the scorching heat of summer arrives, your air conditioner becomes your best friend, providing a cool and comfortable indoor environment. However, like any other appliance, air conditioners can encounter issues and may require attention.

Hiring a professional HVAC contractor can help ensure that your home stays cool this summer. But how do you know if your AC needs regular servicing or if it’s time for repair? Understanding the difference between air conditioner service and repair is crucial to ensure the optimal functioning and longevity of your cooling system.

Let’s explore this difference so you can make an informed decision about maintaining your HVAC system.

Air Conditioner Service: Preserving Peak Performance

Air conditioner service plays a pivotal role in preserving the peak performance of your cooling system. Regular servicing involves comprehensive maintenance tasks performed by professionals. Let’s delve into the key components of air conditioner service:

1. Cleaning And Inspecting Air Filters

Air filters are an underrated but important component of your air conditioning unit. They trap dust, allergens, and debris, preventing them from circulating through your home. During a service, technicians clean and inspect these filters, ensuring they function optimally. Clean filters not only improve indoor air quality but also enhance energy efficiency.

2. Checking Refrigerant Levels

Refrigerant is the lifeblood of your air conditioner. It absorbs heat from indoor air and transfers it outside, cooling your home. Technicians measure refrigerant levels during service visits to ensure there are no leaks or imbalances. Adequate refrigerant levels are essential for optimal cooling performance.

3. Lubricating Moving Parts

Air conditioners have numerous moving parts that require proper lubrication to reduce friction and wear. During servicing, technicians lubricate these components, minimizing the risk of breakdowns and extending the lifespan of the unit.

4. Cleaning Condenser And Evaporator Coils

Condenser and evaporator coils are responsible for heat exchange in your air conditioner. Over time, these coils accumulate dirt and grime, hindering heat transfer. Cleaning them during service improves energy efficiency and helps prevent system failures.

5. Calibrating Thermostat

A well-calibrated thermostat ensures your AC operates at the desired temperature, providing comfort and energy savings. During service, technicians calibrate the thermostat to guarantee accurate temperature readings.

6. Inspecting Ductwork

Leaky or clogged ductwork can reduce cooling efficiency and waste energy. As part of this service, professionals will inspect your ducts for any issues and recommend repairs if necessary.

Air Conditioner Repair: Addressing Malfunctions

While regular service helps prevent breakdowns, air conditioner repair becomes necessary when malfunctions occur. Repairs are specific interventions to address issues and restore the unit’s functionality. Let’s explore some common scenarios that may require AC repair:

1. No Cool Air Blowing

If your air conditioner is running, but no cool air is coming out, it’s a sign of a problem. This issue could be caused by a faulty compressor, refrigerant leak, or a malfunctioning fan motor. A repair expert can diagnose the exact issue and provide a solution.

2. Inadequate Cooling

Inadequate cooling might occur if your AC is struggling to reach the desired temperature or takes longer to cool the space. This could be due to dirty coils, a failing compressor, or restricted airflow. A repair expert can address the root cause and restore efficient cooling.

3. Strange Noises

Unusual sounds like grinding, banging, or screeching may indicate loose parts, worn-out belts, or motor issues. Ignoring these noises can lead to more significant problems. Timely repairs can resolve the source of the noise and prevent further damage.

4. Constant Cycling On And Off

Frequent cycling on and off, known as short cycling, can strain your air conditioner and increase energy consumption. This may be caused by an oversized unit, faulty thermostat, or refrigerant imbalances. A repair service can identify the cause and prevent unnecessary wear on the system.

5. Water Leaks

Water leaks around your AC unit are a sign of trouble. They may result from a clogged condensate drain or a refrigerant leak. Repairing the leak and fixing the drainage issue is crucial to prevent water damage and mould growth.

6. Foul Odours

Foul odours emanating from your air conditioner can be unpleasant and indicate mould or bacterial growth within the unit. A professional can clean the system and eliminate these odours, improving indoor air quality.

7. Electrical Issues

Electrical problems can pose safety hazards and cause your AC to malfunction. If you notice sparking or unusual electrical behaviour, it’s essential to call a repair technician promptly to address the issue.

Air Conditioner Service Vs. Repair: When To Choose What

Now that we’ve explored the differences between air conditioner service and repair let’s understand when to opt for each:

Air Conditioner Service Frequency

Regular air conditioner service is recommended to keep your cooling system in top condition. For most residential units, a yearly service is sufficient. However, in regions with heavy AC usage or harsh climates, bi-annual servicing may be more appropriate.

Signs That Indicate An Immediate Repair Is Needed

If you encounter any previously mentioned AC malfunctions, it’s time for a repair. Additionally, if you notice a sudden spike in your energy bills or a decline in your system’s cooling performance, it’s wise to call a professional for inspection and repair.
