When the heat sets in, a properly functioning air conditioning system becomes more than a luxury – it’s essential for your comfort, energy efficiency, and even your health. Below are 7 common signs your residential or commercial air conditioner may need professional servicing.
Why act early?
- Catching and fixing small issues now can:
- Reduce repair costs by up to 30%
- Prolong the lifespan of your AC system
- Ensure full compliance with UK F-Gas regulations
1. Warm Air Instead of Cool Comfort
If your air conditioner is blowing warm air despite a low thermostat setting, it could be a sign of low refrigerant, compressor failure, or a faulty check valve.
What to do: Turn off the system and contact our F-Gas certified engineers for a same-day pressure check.
Uneven cooling or barely-there airflow usually points to clogged filters, fan issues, or a ductwork leak. These issues not only reduce comfort but also force the system to work harder-raising your energy bills.
3. Unusual or Louder Noises
Grinding, buzzing, or clicking noises from your unit may signal a mechanical fault or electrical issue. Left unchecked, a minor component failure can lead to major AC damage.
Switch off the unit and schedule an inspection before further damage occurs.
4. Unpleasant Odours Near the Unit
A musty smell could mean mold inside the ducts or drip tray. A burning smell might point to an overheating component, while a sweet, chemical scent could indicate a refrigerant leak-which is hazardous and must be addressed immediately.
5. Sudden Spike in Your Energy Bills
If your energy usage hasn’t changed but your monthly utility bill has jumped by 10–20%, your AC could be operating inefficiently. Common causes include dirty coils, low refrigerant, or a faulty thermostat.
A simple service visit often pays for itself within the season.
6. Short Cycling or Constant Running
If your unit turns on and off too frequently – or runs continuously, it could mean the system is oversized, the coils are dirty, or the thermostat is malfunctioning. Either way, your AC will wear out prematurely.
7. Leaks, Moisture, or Water Drips
Water around the indoor unit usually means a blocked condensate drain. Oily stains around the unit may indicate a refrigerant leak, which is both dangerous and a compliance issue under F-Gas regulations.
Immediate attention is essential in either case.
