Our work
A selection of installations we've completed around St Albans and the surrounding areas — from single-room home systems to full commercial projects.
Domestic installations
Air conditioning for homes
Examples of systems we've installed in homes around St Albans, with the details of each unit.
Mitsubishi Electric 2.5kW wall-mounted indoor unit
Around 9,000 BTU — well suited to a bedroom, study or small living room. R32 inverter heat pump, so it both cools in summer and heats efficiently in winter, with sound levels down to roughly 19–21 dB(A) on low fan and A+++ rated seasonal efficiency.
Daikin 2.5kW outdoor condenser
The matching outdoor half of a single-room (pair) system. R32 refrigerant, inverter-driven compressor for lower running costs, blue-fin anti-corrosion coated heat exchanger for weather resistance, and heating operation down to around -15°C outdoors.
Mitsubishi Electric 6kW wall-mounted indoor unit
Around 21,000 BTU — sized for larger living rooms, open-plan spaces and offices. R32 inverter heat pump with multi-stage filtration, wireless controller and quiet operation, delivering full heating capability as well as cooling.
Budget-friendly option
From £1,300Haier air conditioning, installed properly
Alongside our Mitsubishi, Daikin and Toshiba installations, we also fit Haier’s wall-mounted air conditioning range — a budget-friendly option that keeps the quality high while keeping the price down. It’s ideal if you want reliable heating and cooling in a single room, without the premium price tag.

Commercial installation
Air conditioning for commercial properties
Youth Talk is a St Albans charity providing free counselling for young people. We designed and installed a complete air conditioning system across their offices and counselling rooms — 12 wall-mounted indoor units in total, giving each room its own independent temperature control for year-round heating and cooling.
- 12 Mitsubishi Electric wall-mounted indoor units across offices and counselling rooms
- Individual room control so every space can be set to its own temperature
- Quiet-running units chosen specifically for confidential counselling sessions
- Neat external pipework routed to keep the building's appearance intact
- Installed with minimal disruption to the charity's day-to-day work
“After a competitive tender process we used Andy for the installation of air conditioning across our office spaces and counselling rooms — and we have been absolutely delighted we selected AF Clark Ltd! The customer service from day one, the quality of workmanship, the general advice and the after sales service we have received from Andy has been second to none. Highly recommend.”
