Why do I need my air conditioning unit serviced?

Before we explore what an air conditioning unit service includes, it’s important to understand why regular maintenance is important. Failing to properly maintain your AC system can lead to a myriad of problems. Fortunately, regularly servicing your AC unit can safeguard against such issues from occurring. Here’s why servicing your air conditioning unit is so important for its function and lifespan.

  • Improved Efficiency

A regular AC unit service can ensure optimal performance for your system. With improved efficiency, you can rest assured that your air conditioning unit is working at peak performance, improving efficiency and lowering the cost of your energy bills.

  • Extended Lifespan

Regularly servicing your air conditioning unit facilitates a longer lifespan for your system. Air conditioning systems are manufactured to be long-lasting, but only if regular maintenance is undertaken to safeguard against issues.

  • Prevents Breakdowns

Our engineers will complete thorough inspections and tests on your air conditioning unit. These tests will identify any potential issues before they become major – and more expensive, problems in the future.

  • Better Air Quality

When it has been serviced and is fully functioning, your AC system is great at improving air quality. By filtering out ‘dirty’ air your air conditioning system works hard to replace it with clean, fresh air. This means that you’ll be cooler and able to breathe more easily.

  • Reduces Health Issues

A fully functioning air conditioning unit provides better quality air, therefore lowering the risk of triggering health problems. With toxins, dust and debris removed from your property, this is a great benefit for those with health problems and allergy sufferers alike.

  • Increased Productivity

Commercial areas can benefit from AC servicing by creating a comfortable working environment for your employees. When employees are comfortable, they will likely be more productive, whether in an office, warehouse or factory.

  • Environmental Benefits

When air conditioning is functioning as it should, it can contribute to lower energy consumption. This lower energy consumption will reduce your carbon footprint – a great benefit to the environment.

  • Consistent Comfortable Temperatures

Servicing your air conditioning unit ensures that you enjoy consistently comfortable temperatures in your home or commercial space. See inconsistent cooling and heating become things of the past with regular AC servicing.

  • Maintain Your Warranty

Your air conditioning unit likely comes with a warranty, and servicing it is often a warranty requirement. Ensure that you preserve your warranty coverage and protect your investment with AC system servicing.

  • Peace of Mind

Regularly servicing your air conditioning unit provides you with peace of mind that your system is functioning as it should. What’s more, you can enjoy hassle-free cooling and heating throughout the year.

For your air conditioning unit to work properly and to ensure its lifespan, an annual air conditioning service is recommended. Get in touch with us for a FREE survey and quote today!

How do I know if my air conditioning unit needs servicing?

If you’re not sure if your air conditioning system needs servicing, here are some warning signs to look out for…

  • Low refrigerant: Is your air conditioning unit struggling to cool or heat your property? If so, this could be a sign of low refrigerant levels, indicating the need for servicing.
  • Frozen evaporator coils: Frozen evaporator coils are a sign that your air conditioning unit isn’t functioning properly and requires immediate attention.
  • Dirty condenser coils: When dust or debris collects on the condenser coils, this can impact heat transfer, leading to poor cooling performance.
  • Fan problems: Have you heard unusual noises or spotted weak airflow? If so, then your air conditioning unit may have an issue that a service can identify and repair.
  • Leaking ducts: Moisture or water stains around your ductwork suggest leaks, which can compromise system efficiency and indoor air quality, requiring prompt servicing.
  • Thermostat problems: Is your thermostat exhibiting problems such as inaccurate temperature readings or unresponsive controls? A service could quickly rectify the problem.
  • Clogged drains: Clogged drains are identified by water around your unit or overflowing from the drain. Servicing your unit will prevent water damage and mould growth.

If you’ve noticed that your air conditioning unit is showing signs of any of the above problems, please don’t hesitate to get in touch with us today.

What does an air conditioning service include?

With regular servicing, we have seen air conditioning units last for up to 20 years. However, to achieve this, an annual air conditioning service is recommended. By investing in regular servicing, homeowners can stop problems and breakdowns in their tracks while enjoying a consistently comfortable indoor environment. Here’s everything that’s included in an AC unit service…

  • Visual Inspection

We will visually inspect your whole air conditioning unit. This visual inspection includes any indoor and outdoor units, ductwork, and any other components.

  • Cleaning

With regular use, dirt, dust and debris can collect in your AC unit, impacting its performance. We will clean the condenser coils, evaporator coils, filters, and other components.

  • Filter Replacement

We will inspect the filters to assess their condition and, if necessary, will replace them to ensure good air quality and effective airflow.

  • Checking Refrigerant Levels

We will assess the refrigerant levels to ensure they are at the appropriate level. If the levels are low, we may need to add refrigerant to the system.

  • Inspecting Electrical Connections

Loose or damaged electrical connections can cause problems with your AC system. Therefore, we will inspect all electrical connections and tighten them if needed.

  • Checking Thermostat

Your air conditioning system’s thermostat is responsible for temperature control. We will inspect the thermostat to ensure it is functioning properly and calibrate it if necessary.

  • Inspecting Ductwork

If we’re able to access it, we will inspect the AC system’s ductwork for any leaks or damage that could be impacting the performance of the system.

  • Testing System Performance

Once we have cleaned and inspected your air conditioning unit, we will test the system to ensure it is operating properly and efficiently.

  • Providing Recommendations

Based on our inspection, we may provide recommendations for any repairs or improvements that could enhance the performance of the air conditioning unit.
