Office, shop or industrial site? Commercial air conditioning Something's wrong? Try the fault finder
That's an installation.
A 2.0 to 2.5 kW wall unit usually covers a bedroom. On its lowest fan a good one runs at around 20 dB, and with the vane set to blow along the ceiling it won't pour cold air onto the bed. In a loft the pipes run down the outside wall in white trunking, or inside through a cupboard.
Bedrooms and loftsThat's an office job.
Meeting rooms fill and empty fast, so they need their own unit and controls, separate from the open-plan floor. Each person adds around 100 W of heat, and computers and screens add to that - we size from the total, not from the floor area.
Commercial air conditioningThat's a repair.
Water from an indoor unit is most often the drain - blocked with dust and slime, or a condensate pump that's given up. Send the code with the make and model from the label, and the visit starts with a good idea of what's wrong.
Try the fault finderThat's a service.
Then there's probably a grey felt of dust on the filters and black specks of mould on the fan barrel. A service clears both, flushes the drain, checks the refrigerant, and gets it running as close to new as its age allows.
What a service covers Planned maintenance and F-Gas records for business sitesA rough guide to start with. The survey measures properly, because glass, sun, insulation and how you use the room all move the number.
Most modern split units are heat pumps. In heating mode they pull warmth out of the outside air - even when it's close to freezing - and move it indoors. A plug-in fan heater turns 1 kW of electricity into exactly 1 kW of heat.
So the unit you fit for July can sensibly heat a garden room, loft or conservatory from October to April as well.
Typical figures. Output drops in a hard frost, but stays above the heater's.
Based in Waterlooville. The shaded area is where we work most; if you're just outside it, ask anyway.
Near the sea? Salt air corrodes outdoor units faster. In Southsea, Hayling and Emsworth we'll talk about coated coils and siting the unit out of the wind and spray.

Cooling pulls moisture out of the air - several litres on a humid day. It runs through a small pipe to an outside drain or gully, or to a quiet pump where gravity can't do the job.
Not if it's placed well. The vane can sweep or be set to send the air along the ceiling, and we position units so beds, sofas and desks aren't in the stream.
Typically 45 to 55 dB at a metre - about a quiet conversation. We site it away from bedroom windows, yours and the neighbours'.
It depends on the property and where the outdoor unit goes. Listed buildings, conservation areas, flats and front-facing walls can all be different. We'll talk it through at the survey and point you to your council where it's needed.
Usually, yes. Send us the make and model from the label on the side or underneath of the indoor unit, plus any error code it's showing.
Once a year in most homes; every six months in busy offices, salons, kitchens and dusty spaces. The servicing page has the detail.
Tell us what it's for, roughly where it is and the best way to reach you. That's enough to start.
