Troubleshooting your ducted air-conditioning

by | Jun 8, 2023

Ducted air conditioning systems are an investment for homeowners in Melbourne and surrounding suburbs looking to beat the heat during summer months. These systems provide effective cooling for homes of all sizes but can pose problems for homeowners when they malfunction. Some of the most common problems faced by ducted air conditioning system owners include a malfunctioning blower, leaking ducts, and an unusually noisy system. In this article, we will cover the most common issues and provide practical tips on how to troubleshoot and fix these problems.

  1. Malfunctioning indoor fan coil
    One of the most common issues faced by homeowners with ducted air conditioning systems in Melbourne is a malfunctioning fan coil. A damaged or faulty blower can reduce the system’s cooling efficiency, making the room hotter than usual. To troubleshoot a malfunction blower, check the thermostat and ensure that it’s set at the right temperature. If the blower still doesn’t function, check for dirty air filters as this often causes the blower to malfunction. Regularly clean or replace air filters for optimal performance.
    If the blower still doesn’t work, check for a tripped circuit breaker or a blown fuse. If you aren’t sure how to check, this is a good time to contact a licensed professional to prevent damaging the system further.
  2. Leaking Ducts
    Leaking ducts are a common issue faced by households using ducted air conditioning. Leaky ducts can reduce the cooling efficiency of the system, which can lead to higher energy costs. To troubleshoot this problem, inspect the ducts for holes or gaps and seal any gaps found with mastic sealant. If you aren’t comfortable doing this yourself, contact a professional. A professional can diagnose the issue and seal any gaps or holes to prevent further leaking. Regular inspection of the ducts can prevent this problem from worsening.
  3. Unusually Noisy System
    Ducted air conditioning systems can be noisy if there are loose parts or faulty components. A noisy system can also occur when the bearings of the blower fan wear out and need replacement. To troubleshoot this issue, inspect the system for any loose parts or faulty components, such as the blower or motor bearings. Tighten any loose parts or replace any faulty components. Replacement parts are available through licensed HVAC service providers.
    If your system continues to be noisy, it may be time to schedule a maintenance check. Licensed professionals can provide cleaning services and offer tips on regular maintenance to keep your system running smoothly.
    In conclusion, ducted air conditioning systems can perform well if maintained and serviced regularly. When experiencing problems, it’s essential to troubleshoot and resolve them promptly to prevent further damage. Do not hesitate to contact a licensed professional when in doubt, as they can diagnose and fix problems better. Remember to keep the system well-maintained to ensure optimal performance and comfort!
