Air conditioning questions, answered clearly.

Installation price depends on the room heat loads, equipment, pipe and condensate routes, electrics, access and making good. We survey the project and provide a written quote with its assumptions, inclusions and exclusions.

The programme depends on the number of rooms, equipment, routes, access and any enabling work. We confirm the proposed schedule after the survey and before work starts.

Permission and consent depend on the property, location, lease or freeholder rules, proposed siting and current planning requirements. Check with the relevant authority and property decision-maker before work; a survey can identify questions but cannot grant permission.

The maintenance scope depends on the equipment, condition and reason for the visit. Before booking, we identify the system and confirm the included inspection, cleaning and functional checks, reporting and exclusions.

Tell us the symptoms, model and any error code. If there is water near electrics, a burning smell or another immediate safety concern, stop using the system if it is safe to do so and follow the manufacturer's safety guidance. We confirm the diagnostic scope, charge and available appointment before booking.

Some air-to-air systems are reversible and can heat as well as cool. The proposal should identify the selected system's functions; actual performance depends on the equipment, outdoor conditions, room and use.

Running cost depends on the system, room, setpoint, weather, electricity tariff and how long it runs. We explain the expected efficiency and assumptions for the proposed system in the written quote.
