Sweltering Melbourne summer days can be really unforgiving. In the middle of the blistering heat, the comforting breeze of an air conditioner is essential to staying cool. However, when we most need relief, some of us are instead met with warm air or, even worse, no airflow at all. The culprit? An improperly maintained air conditioning unit.

This brings us to today’s topic. Servicing your air conditioner regularly is by far the best way to maintain the cooling efficiency of your unit. In this article, we explore some of the warning signs your air conditioner needs some TLC, and measures you can take to get it back on track.

1. No Cold Air

There’s nothing quite as disappointing as a failing air conditioner on a hot summer day. If you’ve noticed that your air conditioner isn’t blowing cold air, it’s time to examine the possible reasons and the necessary solutions.

One of the common culprits for an underperforming air conditioner is low refrigerant levels. The refrigerant, also known as coolant, is the substance that your air conditioner uses to remove heat from the air. When the refrigerant levels are low, the air conditioner can’t adequately cool the air circulating in your home, resulting in warm air coming out of your vents.

So, what are the likely causes? This issue is generally the result of a refrigerant leak or insufficient refrigerant during installation. Regardless of the root cause, both scenarios require professional assistance. An HVAC technician has the technology and know-how to identify and fix any leaks, then recharge your system with the correct amount of refrigerant. Unlike a quick clean of your filter, this is a job that should always be left to the professionals.

Another potential issue is a broken compressor. The compressor is responsible for compressing the low-pressure, low-temperature refrigerant from your indoor unit’s evaporator coil. When the compressor fails, the entire cooling process is disrupted, and your air conditioner may either blow warm air or no air at all.

Compressor issues can be due to various factors, including age, electrical problems, or overheating. A broken compressor might need to be replaced, which can be quite costly. However, regular maintenance can help prevent severe compressor issues by ensuring the electrical components are in good shape, and the system isn’t overheating.

While these are two of the most common issues, other problems could cause your air conditioner to blow warm air. These include a dirty air filter or a malfunctioning thermostat.

2. Inconsistent Temperatures

It’s not unheard of to experience uneven cooling in different parts of their home. You might find your living room is nice and cool while the bedroom feels more like a sauna.

The key question here is – why does this happen? Inconsistent temperatures can be a telltale sign that your air conditioner needs servicing, specifically of your vents or thermostat.

Blocked vents are a common cause of uneven cooling. Dust, debris, and other obstructions can accumulate over time, blocking the free flow of cool air to various parts of your home. This scenario can lead to a cooler environment in some rooms and warmer in others.

A faulty thermostat may also be the cause. If the thermostat is unable to accurately gauge and control the temperature, it can lead to certain rooms not receiving the desired amount of cooling. This can be due to a multitude of reasons, from a simple battery issue to complex wiring problems.

Regular air conditioner servicing is highly recommended to clean and clear these vents and check the accuracy of your thermostat, ensuring your home benefits from uniform cooling.

3. Strange Smells or Noises

The quiet hum of an air conditioner is a familiar sound to most homeowners, but when you start to hear abnormal sounds from your air conditioner, such as clanking, buzzing, or whistling, this can be worrying. These noises often indicate underlying issues. 

A malfunctioning fan, for instance, might emit a rattling or buzzing noise, which could signal loose parts or a failing motor. An HVAC technician will be able to assess the noise, find the source and correct it before there is any serious damage.

Similarly, a distinct, unpleasant smell wafting from your air conditioner is a clear sign that your unit requires immediate attention. An air conditioner not only cools your home but also dehumidifies the air, creating an environment inhospitable to mould growth. 

However, if mould does take root in the unit, it will produce a musty smell that can permeate throughout your entire home. This could pose potential health risks to you and your family, including allergy symptoms and respiratory issues. Also, keep a nose out for burning smells, which might indicate dust buildup or something more serious, like a sparking wire igniting insulation.

4. Unusually High Energy Bills

Has there been a recent and unexplained surge in your energy bills? While numerous factors could be at play, your air conditioner might very well be the culprit. When blockages, faults, or inefficiencies within the system force your AC unit to work harder to cool your home, it consumes more electricity. This increased power usage can result in a noticeable rise in your energy costs.

Understanding why your air conditioner is using excess power requires delving into the intricacies of its operation. Blockages, for example, can occur in the air filter, ductwork, or even the outdoor unit, restricting airflow and forcing the system to work overtime. Faulty components – such as a malfunctioning thermostat or a broken fan motor – can also cause the unit to run inefficiently, wasting energy in the process.

Regular AC servicing can uncover these issues, ensuring your air conditioner operates at peak efficiency. A thorough service typically includes cleaning or replacing filters, checking for and repairing leaks, and ensuring all components are in good working order. Professionals will also inspect the thermostat settings and refrigerant levels, two factors crucial for efficient operation.

5. Frequent Repairs and Breakdowns

Is your air conditioner breaking down often? Are you frequently calling in repairs? These are signs of an ageing or malfunctioning air conditioner. Regular servicing can help identify if it’s time to repair or replace the unit, saving you money in the long run.

Let’s delve deeper into this. It’s a common misconception that the more a product is used, the quicker it will degrade. However, with air conditioning units, it’s not so much the usage but rather the lack of proper and regular maintenance that leads to frequent breakdowns.

Like any piece of machinery, an air conditioner has many components, each with its own lifespan. Over time, these parts can wear out, leading to performance issues and breakdowns. Regular servicing can identify potential problems early on, enabling you to replace parts before they completely fail and cause further damage to the unit.

What’s more, regular air conditioner servicing can also improve the efficiency of your unit. A well-maintained air conditioner doesn’t have to work as hard to cool your home, which can result in lower energy bills.

Frequently Asked Questions

What happens if I don’t get my air conditioning unit serviced?

Neglecting your air conditioner’s service can lead to a multitude of problems. The most immediate impact is decreased efficiency. Your system may have to work harder to maintain cool temperatures, resulting in higher energy costs. Over time, dust and debris build-up can cause blockages, further straining the system and potentially leading to breakdowns. In more severe cases, lack of maintenance can lead to a complete system failure, requiring costly replacements. Furthermore, mould and bacteria can grow in unattended air conditioners, affecting your indoor air quality and potentially causing health issues.

How often should I have my air conditioner serviced?

The frequency of air conditioner servicing depends on several factors, including the age of the unit, its usage, and the environment it operates in. As a general rule, it’s recommended to have your air conditioner serviced at least once a year. This should ideally be before summer to ensure optimal performance during the hot months. However, servicing every 6 months may be beneficial for older units or air conditioners in high-usage or dusty environments.

What does a service include?

An air conditioner service is a thorough process aimed at maintaining efficient operation and prolonging the lifespan of the indoor and outdoor units. It typically includes cleaning the air filters, coils, and fins to remove dust and debris that can hinder airflow. The service provider will also check for refrigerant levels and look for leaks. If necessary, they will recharge the refrigerant. The thermostat will be inspected and calibrated for accuracy. Electrical connections will be tightened, and motor parts will be lubricated to ensure smooth operation. Additionally, the service provider will inspect the condensate drain for blockages and the overall system controls to ensure proper start, operation, and shut-off.
