What Our Air Conditioning Maintenance Covers
1
Preventative System Checks
Our trained engineers examine every part of your air conditioning system to catch small issues before they become costly problems. We check airflow, thermostat operation, and refrigerant levels to keep your system working efficiently all year.
2
Filter Cleaning & Replacement
Clogged or dirty filters restrict airflow, reduce system performance, and compromise air quality. We clean or replace filters as needed to ensure your air remains fresh, clean, and cool.
3
Coil & Condenser Cleaning
Over time, dust and debris build up on your AC coils, affecting heat exchange and energy efficiency. We thoroughly clean the evaporator and condenser coils to keep your AC in London working like new.
4
Drainage Maintenance
Blocked or dirty drain lines can lead to leaks and water damage. We flush and inspect all drainage components to ensure proper moisture removal.
5
Electrical & Component Testing
From wiring to sensors, we test your system’s core components to prevent breakdowns and safety risks. Any wear or damage is noted and discussed with you before further action is taken.
6
Maintenance for All System Types
Whether you’ve got a wall-mounted unit, a ducted system, or a multi-split setup, we’ve got you covered. Our team is trained to service all AC types — and all major brands including Daikin, Mitsubishi, Samsung, Panasonic, Toshiba, and Fujitsu.
