June 26, 2023 Haysadmin No Comments

Experiencing these split system problems? Here’s what you need to know

Living in Brisbane, we’re lucky to enjoy pleasant year-round temperatures. We’re also familiar with the often uncomfortable humidity, particularly during summer.

As such, a reliable air conditioning system is essential to our daily comfort!

However, like any other appliance, split systems can encounter issues that require troubleshooting as well as the assistance of a reliable technician. 

In this blog post, our air conditioning expert will guide homeowners through some of the most common problems they may encounter with their split system, signs to look out for, as well as troubleshooting tips to resolve the issue.

If you’re looking for help for your air conditioning service in Redcliffe, rely on Hays Airconditioning. Enjoy good old-fashioned customer service and get the right solutions to your problems – call Paul today on 0404 614 814 or get in touch online.

Problem #1: Your split system is not cooling!

A split system that fails to keep you cool is hugely frustrating. 

Several factors can contribute to this issue, such as improper thermostat settings, dirty filters, or refrigerant leaks.

Signs to look out for include warm air blowing from the vents, inconsistent temperature regulation, or the system struggling to reach the desired temperature. 

Troubleshooting:

  • Check the thermostat settings and ensure they are set to the desired temperature
  • Clean or replace dirty air filters to improve airflow and efficiency

If the issue persists, contact a professional HVAC expert like Hays Airconditioning. We can inspect the system, identify refrigerant leaks, and perform the necessary repairs to restore cool, clean air to your home once more.

Problem #2: Your split system is constantly turning on and off

If your split system frequently turns on and off, it can indicate an underlying issue.

Signs to look out for include the system repeatedly starting and stopping within short intervals, inadequate cooling or heating, or unusual noises coming from the unit.

This problem, known as short cycling, can be caused by a number of issues. Three of the most common are:

  1. A malfunctioning thermostat that is not properly communicating with the system, causing it to cycle on and off unnecessarily
  2. A dirty evaporator coil, which can disrupt the cooling process and trigger frequent cycling
  3. An outdoor unit obstructed by leaves and debris which is causing the system to overheat and shut off intermittently

Troubleshooting:

In most cases, it’s advisable that you rely on a skilled technician for air conditioning repair in Redcliffe. We will:

  • Ensure the thermostat is functioning correctly and set to the appropriate mode
  • Clean the evaporator coil to remove any dust or debris that may be affecting its performance
  • Check the outdoor unit for any obstructions, such as leaves or debris, and clear them away

Problem #3: Condensation

Excessive condensation around the indoor unit is a common split system problem. It can occur due to poor insulation, clogged condensate drain lines, or inadequate ventilation.

Signs to look out for include water dripping or pooling around the indoor unit, visible condensation on the unit or surrounding surfaces, or a persistent dampness in the air. 

This is an incredibly common problem here in Brisbane, where we can often experience high humidity, particularly during our long hot summers.

Troubleshooting:

Again, we strongly recommend enlisting the help of a qualified professional to troubleshoot the issue, investigate the cause, and provide you with the right solution. As part of your air conditioning service in Redcliffe, Hays can: 

  • Inspect the insulation around the refrigerant lines
  • Clear clogged condensate drain lines and filters
  • Perform in-depth air conditioning cleaning to keep your unit in optimal running condition

Problem #4: Visible mould

Mould growth in and around the split system can pose health risks and affect indoor air quality. It can be caused by excessive moisture, poor maintenance, or inadequate ventilation.

In many cases the mould is visible within the systems vents, however in some cases, it can be hidden deeper within your system. In either case, it’s important to entrust a skilled professional for deep and effective air conditioning cleaning and mould removal. 

Signs to look out for include the presence of visible mould growth on the unit or surrounding areas, musty odour coming from your unit, or any difficulty breathing. If you notice these signs, it’s time to take immediate action!

Troubleshooting:

  • Regularly clean and maintain the split system, including the filters, coils, and drain lines
  • Use a mould-killing solution to clean any visible mould growth
  • Improve ventilation in the room by opening windows or using a dehumidifier, particularly during periods of high humidity

However, if the mould problem persists or is extensive, call Hays Airconditioning immediately. We have the experience, knowledge, and equipment to properly assess the issue and perform in-depth cleaning.

Enjoy clean, cool air all year round with ongoing air conditioning cleaning.

Problem #5: High energy consumption

Excessive energy consumption can lead to higher utility bills and inefficient operation. It can be caused by dirty filters, improper thermostat settings, or a malfunctioning compressor.

Troubleshooting:

  • Clean or replace dirty air filters to improve airflow which in turn will improve energy efficiency
  • Adjust the way in which you use your aircon: optimise thermostat settings to enjoy a more comfortable and consistent temperature in your home, without putting additional strain on your system

If the issue persists, call Hays. We can assess the system’s overall performance and condition (including its age), uncover any hidden issues, and provide the right solution – whether that be repairs, cleaning, or replacement.
