Why Reliable Air Conditioning Matters in London
London’s unpredictable weather means your air conditioning system needs to be ready for anything—from muggy summer afternoons to stuffy office spaces. Regular maintenance and prompt attention to small issues can save you money, improve air quality, and extend the life of your system.
1. Air Conditioner Not Cooling Properly
What’s going on?
If your aircon isn’t cooling as it should, the culprit is often a dirty air filter, a blocked condenser, or an incorrect thermostat setting.
What you can do:
- Check and clean or replace the air filter.
- Make sure the outdoor condenser unit is free from leaves and debris.
- Double-check that your thermostat is set to ‘cool’ and at the right temperature.
When to call a professional:
If these steps don’t help, you may have a refrigerant issue or a more complex fault. For expert air conditioning service in London, our team is always ready to help.
2. Unusual Noises
What’s going on?
Banging, rattling, or squealing noises can mean loose parts, debris inside the unit, or worn-out bearings.
What you can do:
- Turn off the unit and check for obvious loose screws or debris.
- If the noise continues, it’s best to contact a qualified engineer.
3. Water Leaking from the Unit
What’s going on?
Leaks are usually caused by a blocked drain pipe or a frozen evaporator coil.
What you can do:
- Clear the drain pipe if you can access it safely.
- Check for ice build-up on the unit.
When to call a professional:
Persistent leaks or water damage should be dealt with by a specialist to prevent further issues.
4. Air Conditioner Not Turning On
What’s going on?
This could be a power supply issue, a tripped circuit breaker, or a faulty thermostat.
What you can do:
- Check your power supply and reset the circuit breaker if needed.
- Replace the batteries in your thermostat.
When to call a professional:
If your aircon still won’t start, it’s time to book a service.
5. Foul Smells from the Aircon
What’s going on?
Musty or unpleasant smells are often caused by mould or bacteria in the system.
What you can do:
- Clean or replace the filters.
- If the smell persists, arrange for a professional clean.
6. Weak Airflow
What’s going on?
Weak airflow can be due to clogged filters, blocked vents, or a failing fan motor.
What you can do:
- Clean or replace the filters.
- Make sure all vents are open and unobstructed.
When to call a professional:
If airflow remains poor, a technician can check for deeper issues.
