Whether it’s a residential or commercial air conditioning system, if it’s not running at peak performance, it may be time to call in the professionals for a comprehensive cleaning. Several common signs indicate your AC needs some TLC, including:
✔️Reduced Cooling Efficiency:
If you notice that your air conditioner is not cooling your space as effectively as it used to, it may be a sign that the coils or filters are dirty and restricting airflow.
✔️Increased Energy Bills:
A dirty air conditioner has to work harder to cool your space, leading to increased energy consumption. If you see a sudden spike in your energy bills without a corresponding change in usage, it might be time to clean your AC unit.
✔️Poor Airflow:
Insufficient airflow from the vents is a common sign of a dirty or clogged air filter. Reduced airflow can also lead to uneven cooling in different parts of your home.
✔️Unpleasant Odours:
Foul or musty odours can indicate the presence of mould or bacteria in the system. Cleaning the unit and replacing filters can help eliminate these odours.
✔️Visible Dirt and Dust:
If you notice a buildup of dust, dirt, or debris on the vents, around the indoor unit, or on the cooling coils, it's a clear sign that your air conditioner needs cleaning.
✔️Strange Noises:
Unusual sounds like rattling, hissing, or banging can indicate various issues, including loose components or debris in the system. Cleaning the unit and checking for any loose parts can resolve these problems.
✔️Allergies or Respiratory Issues:
If you or your family members experience an increase in allergy symptoms or respiratory issues when the AC is running, it could be a sign of mould or dust circulating in the air. Cleaning the unit and replacing filters can improve indoor air quality.
✔️Water Leaks:
Moisture or water leaks around the indoor unit can be a sign of a clogged condensate drain. This can happen when dust and debris accumulate, hindering the drainage process.
✔️Visible Mould or Mildew:
If you see visible mould or mildew on any part of the air conditioner, including the coils, vents, or ductwork, it's crucial to clean and disinfect the affected areas to prevent further growth.

At Dunn & Williams, we understand how important it is to have a clean air conditioning system. You may wonder how an enclosed unit becomes dirty, and the main reason is that they constantly draw in air from their surroundings, carrying dust, pollen, pet fur, and other airborne particles. Over time, these contaminants accumulate on filters, coils, and fans, reducing airflow and allowing particles to bypass the filter and settle inside. Other culprits are smoke and cooking fumes. Aside from routine cleaning, your AC will benefit from regular maintenance and servicing from an HVAC specialist. If your AC is performing at its best, schedule a professional clean with our skilled team today!
