It is not a case of bolting a box to a wall. The difference between a system that runs quietly at low cost for fifteen years and one that is noisy, expensive and unreliable is almost entirely down to how it was designed and installed. We install air conditioning for homeowners across Basingstoke and Hampshire, and for offices, shops, salons, server rooms, restaurants and light industrial units throughout Berkshire, Surrey and Wiltshire. Every installation starts with a site survey and ends with a full commissioning report, warranty registration and a demonstration of the controls. Modern air conditioning is reverse-cycle heat pump technology. That means the same system that cools your home in July heats it efficiently in October and March, typically delivering three to four units of heat for every unit of electricity consumed. For many of our customers, the heating capability is what justifies the investment rather than the cooling alone. We are an independent installer, which means we specify the equipment that suits your building rather than the equipment a single manufacturer requires us to sell. We regularly install Mitsubishi Electric, Daikin, Panasonic, Samsung, LG and Toshiba systems, and we will explain honestly why we are recommending a particular unit for your property. Air conditioning fully installed starts from £1,100 for a straightforward single-room system. Every quotation we issue is a fixed price. Once we have surveyed and quoted, that figure stands unless you change the scope of the job. ## What Happens If You Wait? The UK's housing and commercial stock was never built for the summers we now get. South-facing bedrooms, loft conversions, extensions with large glazed elevations, and open-plan kitchen-diners regularly climb past 28°C and stay there overnight. Sleep suffers, concentration suffers, and in commercial premises, so does staff productivity and customer dwell time. The usual stopgaps make things worse. Portable units dump heat back into the room through a poorly sealed window hose, draw far more electricity than a fixed inverter system, and produce noise levels that make them useless in a bedroom or an office. Fans move hot air rather than removing it. The single most common installation fault we are called out to correct is incorrect sizing. An undersized system runs flat out and never reaches setpoint, and its compressor wears prematurely. An oversized system short-cycles, switching on and off repeatedly, which leaves the room clammy because the unit never runs long enough to dehumidify properly, and burns through electricity doing it. Both come from guessing the load instead of calculating it. The second most common fault is bad installation practice: refrigerant pipework that has not been properly vacuum-dried before charging, flare joints made without a torque wrench, condensate drainage run without adequate fall, and outdoor units bolted straight to a wall without anti-vibration mounts. Each of these produces a failure that appears six months to three years later, long after the installer has moved on. Correcting them costs considerably more than doing the work properly the first time. There is also a timing problem. Demand for air conditioning installation in Hampshire spikes the moment the first heatwave is forecast, and lead times stretch from days to several weeks. Booking a survey in spring or autumn means faster installation, better equipment availability and a system that is commissioned and working before you need it. ## How We Work 1 ### Free Site Survey We visit your property, measure each room, and assess insulation, glazing area and orientation, ceiling heights, occupancy and any heat-generating equipment. We look at outdoor unit positions, pipe routes, drainage options and your electrical supply. 2 ### Heat Load Calculation & Design We calculate the sensible and latent cooling load room by room, then specify indoor unit types, capacities and the outdoor unit or units to match. You get a written design, not a guess. 3 ### Fixed-Price Quotation You receive an itemised fixed-price quotation covering equipment, materials, labour, commissioning, warranty registration and making good. No day rates, no provisional sums, no surprises on the final invoice. 4 ### Installation Indoor units mounted level and secure, copper pipework flared and torqued, fully insulated and neatly routed, outdoor unit on anti-vibration mounts, condensate drainage run with correct fall, and a dedicated electrical circuit installed to BS 7671. 5 ### Commissioning & Leak Testing The system is pressure-tested with nitrogen, vacuum-dried to remove all moisture, charged to the manufacturer's specification and leak-tested to F-Gas requirements. We record superheat, subcooling and delivered air temperatures in every zone. 6 ### Handover & Aftercare We demonstrate the controls, configure any smart or Wi-Fi features, register the manufacturer warranty in your name, and hand over the commissioning certificate and F-Gas documentation. We then remind you when the first annual service is due. ## Why It Matters ### Fixed Prices from £1,100 Fully installed single-room systems start at £1,100. Your quoted price is the price you pay — surveyed properly so nothing is missed. ### Correctly Sized Every Time Room-by-room heat load calculations mean your system reaches setpoint, dehumidifies properly and does not short-cycle. ### Heating As Well As Cooling Reverse-cycle operation delivers efficient heating through spring and autumn at roughly a third of the running cost of electric heaters. ### F-Gas Certified Work All refrigerant handling, leak testing and record-keeping is carried out by F-Gas certified engineers, keeping you legally compliant and your warranty valid. ### Genuinely Quiet Systems Correctly specified indoor units run from around 19dB on night mode, with anti-vibration mounting and insulated pipework keeping outdoor noise down for you and your neighbours. ### Local Aftercare We are based in Basingstoke, not a national call centre. Servicing, warranty support and emergency callouts come from the same engineers who installed the system. ## Technical Detail & Expertise Indoor unit selection is driven by the room. Wall-mounted high-wall units are the default for bedrooms, living rooms and home offices — they are the most efficient per pound and the quietest. Ceiling cassettes suit open-plan spaces, retail floors and offices with suspended ceilings, distributing air in four directions rather than one. Ducted units hide entirely within a ceiling void or loft and deliver air through discreet grilles, which is the right answer for period properties and anywhere the equipment must not be seen. Floor-standing consoles work well under windows in rooms where there is no suitable wall. Single-split systems pair one indoor unit with one outdoor unit and are the most efficient configuration per room. Multi-split systems run up to five indoor units from a single outdoor condenser, which matters when outdoor space is limited or when planning or aesthetic considerations restrict how many external units you can site. For larger commercial premises we specify VRF and VRV systems, which give simultaneous heating and cooling to different zones from one refrigerant circuit. Refrigerant pipework is run in refrigeration-grade copper with flared connections made to the manufacturer's torque figures, then fully insulated along its entire length to prevent condensation forming inside walls and ceiling voids. Wherever possible we route pipework internally through voids, cupboards and floor structures. Where an external run is unavoidable, we use white or brown Slimduct trunking cut and mitred neatly rather than leaving lagged pipe exposed to UV. Condensate drainage is designed before the units go up. Gravity drainage to an external gully or soakaway is always preferred, with a minimum fall maintained across the whole run and a trap fitted to prevent odour. Where gravity is impossible — typically first-floor and loft installations — we fit a mini condensate pump with an integral high-level safety switch that shuts the system down before any overflow can reach a ceiling. Electrical supply is taken from a dedicated way in the consumer unit, with the correct cable size for the run length, RCBO protection and a local isolator adjacent to the outdoor unit. All electrical work is completed and certified to BS 7671 18th Edition. Where the existing consumer unit has no spare capacity we will identify that at survey stage and price the necessary works rather than discovering it on installation day. Outdoor unit siting is a design decision, not an afterthought. We look for a position with free airflow across the coil, adequate clearance for future servicing, no discharge directed at a neighbour's window or seating area, and a mounting arrangement — ground plinth, wall brackets or floor-standing feet — appropriate to the wall construction and the unit weight. Anti-vibration mounts are fitted as standard on every installation. Most domestic air conditioning installations in England fall within permitted development, subject to conditions on unit size, siting relative to boundaries and noise. Listed buildings, conservation areas and properties with restrictive covenants need checking before we proceed, and commercial installations may require planning consent or acoustic assessment. We flag any of this at the survey stage so it is dealt with early rather than mid-project. Efficiency is worth understanding before you buy. SEER measures seasonal cooling efficiency and SCOP measures seasonal heating efficiency. A well-specified modern inverter system will achieve an SEER above 7.0 and an SCOP above 4.0, meaning it produces four kilowatt-hours of heat for every kilowatt-hour of electricity it draws. Cheaper fixed-speed equipment performs considerably worse, and the difference shows up on your electricity bill every month for the next decade. Once installed, an air conditioning system needs an annual service to hold its efficiency, keep the filters and coils clean for air quality, and maintain the manufacturer's warranty. Systems containing 5 tonnes of CO2 equivalent or more of refrigerant also carry a statutory F-Gas leak checking obligation, which applies to most commercial installations. We cover all of this under our annual maintenance contracts. ### Related Services - [Domestic Air Conditioning](/services/domestic-air-conditioning) - [Commercial Air Conditioning](/services/commercial-air-conditioning) - [F-Gas Air Conditioning Servicing](/services/fgas-air-conditioning-servicing) - [Annual Maintenance Contracts](/services/annual-maintenance-contracts) - [← Back to Homepage](/) ### Service Areas - [Basingstoke](/areas/basingstoke) - [Hampshire](/areas/hampshire) - [Reading](/areas/reading) - [Guildford](/areas/guildford) ## Frequently Asked Questions ### How much does air conditioning installation cost? ### How long does installation take? ### Do I need planning permission for air conditioning? ### Can air conditioning heat my home as well as cool it? ### How noisy is an air conditioning installation? ### Which brands do you install? ### Will installation make a mess of my walls and décor? ### Do you install air conditioning for businesses? ### What warranty comes with the installation? ### How soon can you install? ### Which areas do you cover for air conditioning installation? ## Get a Fixed Price for Your Air Conditioning Installation Free survey, honest sizing advice, and a quotation that does not move.
