Signs Your Commercial Air Conditioning Unit Needs Repair
It’s not always obvious when your commercial air conditioning system is due for repair. We have seen a range of issues in the region’s commercial buildings, from minor annoyances to serious faults. Here’s what to watch for if you want to protect your investment and keep your environment comfortable.
Unusual Noises During Operation
Commercial air conditioners are designed to run quietly, especially in office or hospitality settings. If you hear grinding, rattling, or banging, something isn’t right. These noises can point to worn bearings, loose parts, or issues with the compressor or fan assembly.
Early repair can prevent a simple fix from turning into an expensive breakdown.
Reduced Airflow or Lack of Cooling
If you notice weaker airflow or some areas not cooling properly, there may be a blockage, an air handler problem, or an issue with the fan or ductwork. Reduced airflow doesn’t just impact comfort; it forces the system to work harder and consume more power.
Our technicians diagnose the root cause fast and restore reliable performance across your commercial space.
Increased Energy Consumption or Bills
A sudden rise in energy usage is often a sign of system inefficiency. It could be down to dirty coils, refrigerant leaks, or a failing thermostat. Leaving these issues unchecked leads to wear on the system and much bigger repair costs.
We can quickly identify why your commercial air conditioning system is using more energy and carry out the repairs commercial properties need to get it running efficiently again.
Water Leaks or Excess Moisture
Moisture or pooling water near any part of the unit signals drainage problems, a blocked condensate line, or, in some cases, a refrigerant leak. This is more than a nuisance, as unaddressed leaks can cause slip hazards, damp, mould, or corrosion.
We check all drainage and cooling lines, ensuring your system stays safe and reliable for everyone on site.
If you’re noticing any of these signs in your commercial building, We are ready to help our customers with prompt, thorough repair and honest advice. Reach out for a tailored assessment and keep your business running smoothly.
