FAQs
Why is annual air-conditioning servicing important?
Having your air-conditioning system serviced once a year keeps it running safely, efficiently and reliably. During a Lancing summer, dust, pollen and salt-laden coastal air build up on indoor and outdoor coils, forcing the unit to work harder and consume more electricity. A professional service removes these contaminants, checks refrigerant levels and looks for small faults before they damage compressors or circuit boards. Regular maintenance also helps preserve healthy indoor air quality, reduces the risk of breakdowns at the height of the cooling season and is often required to keep the manufacturer warranty valid.
What is included in your annual AC service visit in Lancing?
Our F-Gas certified engineer carries out a comprehensive 12-point inspection: 1) visual examination of indoor and outdoor units, 2) cleaning of evaporator and condenser coils, 3) removal and sanitising of filters, 4) clearing and flushing of condensate drains, 5) tightening of electrical connections, 6) refrigerant pressure and temperature checks, 7) leak detection using approved methods, 8) fan-motor and compressor amperage test, 9) thermostat calibration, 10) inspection of insulation and pipework, 11) verification of overall system performance, and 12) issue of a written service report with any recommendations. All standard consumables and minor adjustments are included in the fixed service price.
How long will a routine domestic AC service take?
For a single split or multi-split system in a typical Lancing home, a standard annual service usually takes between 60 and 90 minutes. Larger properties with several indoor heads or light-commercial premises with VRF/VRV equipment can take 2–3 hours. We schedule appointments in two-hour windows and call ahead so you know when the engineer is on the way, minimising disruption to your day.
Will servicing my air conditioner lower my energy bills?
Yes. Studies by the Carbon Trust show that a heat-pump or air-conditioning system can lose 5–10 % efficiency each year if filters and coils are not cleaned. A tuned, properly charged system requires less electricity to reach the set temperature, which directly reduces your monthly bills. Our service also checks the controls so the unit does not short-cycle or run at an unnecessarily low temperature—both common causes of wasted energy.
Are there warning signs that my AC needs attention before the annual service is due?
Watch for reduced airflow, rooms that take longer to cool, sudden increases in electricity use, musty odours, water dripping from the indoor unit, ice forming on pipework, or unusual rattling or hissing sounds. These symptoms often point to blocked filters, low refrigerant, a failing fan motor or a drain line problem. Contact us as soon as you notice any of these issues; prompt repairs prevent more costly damage and keep your home comfortable.
Do I need yearly servicing to keep my warranty and stay compliant with regulations?
Most leading manufacturers—including Daikin, Mitsubishi Electric and Fujitsu—require proof of annual maintenance by a qualified engineer to maintain their 3–5 year parts warranties. In addition, UK F-Gas regulations obligate owners of systems containing more than 5 tonnes CO₂-equivalent of refrigerant to have documented leak checks at least once a year. Our service visit meets these requirements, and we provide a stamped service log and F-Gas certificate for your records.
