We talk about facts you can verify before we set foot on your driveway. [Request a Weymouth quote](/contact) [01202 144008](tel:+441202144008) Bournemouth-based — 50 minutes from Weymouth 17 years' specialist air conditioning experience F-Gas registered engineers Daikin, Mitsubishi Electric, Panasonic, Fujitsu accredited Rapid response across Dorset & Hampshire Fully insured · Company No. 15463021 Local issues we see in Weymouth ## What goes wrong in DT3–DT4, and how we fix it. Climate, salt air, building age and infrastructure all leave fingerprints on air conditioning systems. These are the patterns we see week in, week out. ### Extreme salt-air exposure along the Esplanade and Portland Harbour Weymouth's south-facing seafront and the exposure to Portland Harbour create some of the harshest marine conditions on the Dorset coast. Standard aluminium condenser fins can pit and lose efficiency within two winters here. Every DT4 install we quote includes a Blygold or equivalent protective coating on the outdoor coil, and annual services along the Esplanade include a fresh-water rinse, fin straightening and electrical-terminal treatment. ### Listed and conservation-area constraints in the old town and Melcombe Regis Large parts of DT4 around the Esplanade, St Mary Street and Melcombe Regis sit inside conservation areas, and many townhouses are listed. Visible front-elevation condensers won't pass Dorset Council planning. We survey for screened side-return, rear-courtyard or flat-roof positions, use colour-matched trunking and, where useful, submit the pre-application enquiry so the install goes ahead without an enforcement risk. ### Holiday-let downtime through the summer season Weymouth's DT3 and DT4 holiday-let market runs at full occupancy from May through September. A cooling failure in July costs a landlord more in refunded nights than the repair itself. We prioritise Weymouth holiday-let no-cool calls, stock the common Daikin and Mitsubishi parts on our Bournemouth shelves, and hold every letting agent's job records on file so callouts don't start from scratch. ### Long pipe runs in tall Georgian townhouses along the Esplanade Three- and four-storey Esplanade townhouses often need the outdoor unit at the rear ground floor and the indoor head on the top floor. Manufacturers cap total refrigerant pipe length and vertical lift; oversizing without adjusting the charge is one of the commonest reasons Weymouth systems fail early. We size the system specifically to the run, add the correct extra refrigerant charge and fit line-driers where the length warrants it. Our process ## Same system every job. No improvising on your floor. 1. 01 ### Free site survey We look at the actual property, the layout and the existing services before we quote. 2. 02 ### Fixed written quote Itemised — no vague allowances, no commission upsells.

Adapt HQ Lower Flat, 7 Windermere Road Bournemouth BH3 7LF [01202 144008](tel:+441202144008) ### Why Weymouth customers use a Bournemouth-based specialist Fifty minutes on the A35 sounds long, but the alternative for most Weymouth customers is a Southampton or Poole firm without any Weymouth stock, a Yeovil firm without any coastal experience, or a general handyman without F-Gas certification. Our Bournemouth workshop holds Daikin, Mitsubishi Electric and Panasonic parts on the shelf — capacitors, PCBs, sensors, fan motors and R32 refrigerant — so most Weymouth repair calls are fixed on the first visit rather than ordered and rebooked. For DT3 and DT4 holiday lets running full through July and August, that difference is the entire justification for the postcode. ### Air conditioning installation across DT3 and DT4 We install Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries, Panasonic, Fujitsu and LG split, multi-split and small VRF systems across Weymouth. Every install starts with a free property survey — actual heat-load calculation against glazing, orientation, occupancy and the specific microclimate of the Esplanade, harbour or Portland-side positions. For any DT4 property within a kilometre of the sea we specify a coated condenser as standard. The written quote itemises the unit, bracketing, trunking colour, F-Gas commissioning and warranty registration. Fixed price — no day-rate surprises on the invoice. ### Servicing and F-Gas compliance for Weymouth homes, lets and commercial sites Domestic split systems need a full annual service to stay within manufacturer warranty: filter, coil and condensate clean, electrical readings and refrigerant pressure check. Commercial systems and any unit holding more than 5 tonnes of CO₂-equivalent refrigerant need a logged F-Gas leak inspection under EC 517/2014 and the GB F-Gas Regulations. We hold every Weymouth customer's job sheets, refrigerant logs and warranty paperwork on file, send a reminder ahead of each service and email certificates the rapid response. ### Rapid-response air conditioning repair across Weymouth Common DT3 and DT4 faults: salt-corroded condenser coils along the Esplanade and Portland Harbour, blocked condensate pumps in attic-mounted units, capacitor failures on five-to-eight-year-old outdoor units, and refrigerant leaks at flare joints where original pipework was cut too short. We diagnose the root cause, repair it, then prove it with a pressure test and electrical readings. Never a refrigerant top-up without finding the leak — a recharge without the repair is a £400 plaster that fails again inside the season. ### Commercial air conditioning across Weymouth harbour and Granby Industrial Estate We maintain VRF, ceiling cassette and ducted systems for hospitality along the old harbour and Hope Square, seafront hotels and guesthouses, and offices, workshops and food-prep units across Granby Industrial Estate in Chickerell. Maintenance contracts are priced per indoor unit per year and include scheduled F-Gas inspections, a written job sheet every visit and a single point of contact for breakdowns. ### Coverage from Weymouth into neighbouring areas From Weymouth we also serve Dorchester, Portland, Wyke Regis, Chickerell, Preston, Osmington, Portesham and the wider south Dorset coast under the same response standards.
