Seven stages, most of them fairly ordinary on their own. Together they explain why the equipment fitted at the end tends to match what the building actually needs.
Most projects start with a short conversation, either by phone or through the contact form, about what is prompting the enquiry. A noisy old air conditioning unit, a boiler nearing the end of its life, a cold room that never quite warms up. This conversation decides whether a site visit makes sense and roughly when.
An engineer visits the property, measures the relevant rooms, checks existing insulation and glazing, and looks at any equipment already installed. This is where questions about daily use come in too: which rooms run cold, which stay too warm, how many people are usually home during the day. The visit is free and does not commit you to anything.
The measurements from the visit become a heat loss calculation for heating projects, or a heat gain calculation for cooling projects, worked out room by room rather than as a single figure for the whole property. Construction type, glazing, orientation and typical air changes all factor into this. It usually takes a few working days, depending on the size of the property.
With the calculation complete, specific equipment gets selected against it, along with pipe or duct routing and a control strategy. The written proposal sets out what is being installed, why that capacity was chosen, and what the commissioning figures should look like once it is running. Nothing in the proposal should read as a surprise if you followed the site visit.
Installation is carried out by Rogeho's own F-Gas qualified engineers. Refrigerant handling, pressure testing, electrical connections and pipe insulation are recorded as the work progresses. For light commercial sites, installation scheduling is usually arranged around opening hours where that matters.
Before handover, the system is run and its readings checked against the figures set out in the design: refrigerant pressures, airflow rates, flow temperatures, whichever applies to the equipment installed. A written commissioning report is provided, along with a walkthrough of the controls for whoever will be using them day to day.
Where a service contract is in place, the first annual visit is scheduled at handover rather than left to be remembered later. Contract holders get priority scheduling ahead of non-contract callouts, which tends to matter most during the first hot week of summer or the first cold snap of winter, when demand for callouts rises across the board.
