FAQs
What does it mean to be F-Gas certified and why is it important?
F-Gas certification proves that our engineers are formally trained and registered to handle fluorinated greenhouse gases safely and legally. Under UK law (retained EU Regulation 517/2014), anyone who installs, services or decommissions air-conditioning or heat-pump equipment containing F-gases must hold this qualification. Certification protects you by ensuring work is completed to strict environmental and safety standards, minimises the risk of refrigerant leaks, and keeps your manufacturer warranty and building insurance valid.
Which air-conditioning services do you provide in Lancing?
We offer a complete suite of services for homes, shops, offices and light-industrial premises in and around Lancing: • System design and load calculations • Supply and installation of single-split, multi-split and VRF/VRV systems • R32 and low-GWP refrigerant upgrades • Planned preventative maintenance (PPM) • 24/7 emergency breakdown response • Refrigerant leak detection and repair • Pressure testing and F-Gas logbook management • Decommissioning and environmentally compliant refrigerant recovery.
How quickly can your engineers respond to breakdowns or call-outs in Lancing?
Because our main depot is only 10 minutes from the centre of Lancing, we can usually attend urgent call-outs within 2 hours during working days. For customers on maintenance contracts, we guarantee a same-day response and keep common spare parts in our vans to resolve over 80 % of faults during the first visit. Out-of-hours emergencies are covered by our 24/7 duty engineer service line.
Do you offer regular maintenance contracts for domestic and commercial systems?
Yes. Planned Preventative Maintenance (PPM) contracts are tailored to your equipment type, usage and warranty requirements. Domestic splits typically need one visit per year, while commercial or high-duty systems may need quarterly visits. Each service includes filter cleaning or replacement, coil disinfecting, electrical safety checks, refrigerant pressure and leak checks, condensate drain cleansing, and a full written report for your F-Gas records. Well-maintained units run up to 30 % more efficiently and experience fewer breakdowns.
How energy-efficient are modern air-conditioning units and can you help me choose the right size?
Current inverter-driven heat-pump air-conditioners can deliver Seasonal Energy Efficiency Ratios (SEER) of 6.0–8.5, meaning they provide 6–8.5 kW of cooling for every 1 kW of electricity consumed under seasonal conditions. Selecting the right capacity is vital: an undersized unit will run continuously, while an oversized one will cycle on/off and waste energy. Our engineers perform a free, no-obligation heat-gain and heat-loss calculation that factors in room volume, orientation, insulation and occupancy to specify the most efficient model for your needs.
What warranties and guarantees come with your installations and repairs?
All new installations come with up to 5 years manufacturer parts warranty (subject to annual maintenance) and 12 months labour warranty from us. Repairs carry a 12-month parts and labour guarantee unless stated otherwise. We are fully insured with £10 million public liability cover and provide F-Gas certificates and commissioning sheets for your records. If any workmanship issue arises within the guarantee period, we will return promptly and rectify it free of charge.
