Air Conditioning Servicing and Repairs in London
Keep your air conditioning operating reliably with professional servicing, maintenance and repairs from ATP Air Solutions.
Our experienced engineers work on domestic and commercial air conditioning systems throughout London. From routine maintenance to investigating an unexpected breakdown, we provide practical advice, clear quotations and professional workmanship.
We service and repair equipment from most leading air conditioning manufacturers.
Professional Air Conditioning Servicing
Regular servicing helps your air conditioning system operate efficiently and reliably. Without suitable maintenance, dust and debris can build up inside the equipment, airflow can become restricted and developing faults may go unnoticed.
During an air conditioning service, our engineer will inspect the system, assess its operation and clean the relevant components. If we identify a fault or recommend additional work, we will explain what is required before carrying out repairs outside the agreed service.
We service air conditioning in:
- Houses and apartments
- Offices and meeting rooms
- Shops and showrooms
- Restaurants and hospitality venues
- Schools and educational buildings
- Server and communications rooms
- Commercial and managed properties
- Multi-tenanted buildings
- Warehouses and industrial premises
Why Air Conditioning Maintenance Matters
A well-maintained air conditioning system is more likely to provide consistent temperatures, effective airflow and dependable performance.
Routine maintenance can help:
The appropriate service frequency will depend on the type of equipment, its operating hours and the environment in which it is installed. A lightly used home system may require less frequent attention than equipment operating daily in a busy commercial property.
Routine maintenance can help:
- Maintain heating and cooling performance
- Improve airflow through the indoor unit
- Keep filters and internal components clean
- Reduce unnecessary energy consumption
- Identify developing problems earlier
- Lower the risk of unexpected breakdowns
- Extend the useful life of the equipment
- Support manufacturer warranty requirements
- Maintain a cleaner and more comfortable indoor environment

Warning Signs Your Air Conditioning Needs Attention
Water Leaking from the Unit
Water dripping from an indoor air conditioning unit may be caused by a blocked condensate drain, damaged pump, incorrect drainage or a problem with the installation.
Continuing to use a leaking system can damage walls, ceilings, flooring and nearby equipment. Switch the unit off if necessary and arrange an inspection.
Unusual or Excessive Noise
Rattling, buzzing, grinding or clicking can indicate a loose component, fan problem, worn motor or debris inside the equipment. Some operational noise is normal, but a new or worsening sound should not be ignored. An early inspection may prevent the affected component from causing further damage.

Not Heating or Cooling Properly
If the air from your unit is no longer reaching the expected temperature, the cause could be restricted airflow, dirty components, incorrect settings, a sensor fault or a refrigerant-related issue. Our engineers can test the system and identify why its performance has reduced.

Rising Electricity Consumption
A poorly maintained air conditioning system may need to work harder to reach the selected temperature. Blocked filters, dirty heat exchangers and mechanical faults can all contribute to unnecessary energy use. If your usage has not changed but electricity consumption has increased, the system may need servicing or further investigation.

If your usage has not changed but electricity consumption has increased, the system may need servicing or further investigation.
Weak or Uneven Airflow
Restricted airflow may be caused by blocked filters, contamination inside the indoor unit, a fan problem or an obstruction elsewhere in the system. Weak airflow can reduce comfort and increase the time needed to heat or cool the room.

Unpleasant Smells
Musty or unusual smells can develop when moisture, dust or contamination accumulates inside an air conditioning unit.
Professional cleaning and inspection can identify the source and help restore cleaner airflow. A burning smell should be treated more urgently, and the system should be switched off until it has been checked.
Error Codes or Flashing Lights
Modern air conditioning systems display error codes or flashing indicator lights when they detect a fault.
Please make a note or take a photograph of the code before contacting us. This information can help our engineer prepare for the visit, although full testing may still be needed to confirm the cause.

System Switching Off Unexpectedly
Repeated stopping, tripping or restarting can be caused by an electrical fault, overheating, blocked airflow, a faulty sensor or a problem elsewhere in the system. Avoid repeatedly resetting equipment that continues to trip. Arrange professional fault diagnosis instead.

Planned Air Conditioning Maintenance
Annual and biannual maintenance options
Planned maintenance makes it easier to keep your equipment in good condition and reduces the chance of important servicing being overlooked.
ATP Air Solutions provides planned maintenance for residential and commercial systems across London. Depending on the equipment and how heavily it is used, servicing can be arranged annually, twice yearly or at another suitable interval.
For commercial clients with several systems, we can create an equipment schedule and plan visits around business operations.
Planned maintenance is suitable for:
- Offices and commercial buildings
- Retail and hospitality premises
- Landlords and managing agents
- Schools and healthcare environments
- Server and communications rooms
- Multi-split air conditioning systems
- VRV and VRF installations
- Heat pump systems
- Residential properties with several units
Air Conditioning Repairs

Server Room Air Conditioning Repairs
Server and communications rooms often require continuous cooling. Even a short interruption can allow temperatures to rise quickly and place valuable equipment at risk.
If your server room air conditioning develops a fault, provide us with the system details, current room temperature and any displayed error code. Where necessary, temporary measures should be taken to protect the equipment until the cooling system is restored.

- Checking filters and cleaning where appropriate
- Inspection and cleaning of accessible heat exchangers
- Checking airflow and temperature performance
- Inspecting condensate drainage
- Checking pumps where fitted
- Listening for unusual operational noise
- Reviewing controller settings and error history
- Inspecting accessible electrical connections
- Examining pipework and insulation
- Checking the condition of the outdoor unit
- Recording identified defects or recommended repairs
