What Marlborough Homeowners Say About Our Air Conditioning Installation Specialists
Replaced a noisy old portable with a proper wall-mounted split in Marlborough. F-Gas registered engineer, refrigerant pipe run boxed in neatly to match the skirting, and they vacuum-tested before commissioning. £3209 all in including the condenser bracket and a 5-year warranty. Cools the room in minutes and the heat-pump mode took the chill off in winter too.
Got a same-week survey for a living-room install in Marlborough. The engineer was REFCOM certified and explained the F-Gas rules clearly with no hard sell. Came in at £2386 fitted, cheaper than the national chain quote. Tidy work, dust sheets down, and they took the old unit away.
Two indoor units off one outdoor condenser at our property in Marlborough. One neat outdoor condenser instead of boxes everywhere, independent control in each room, and the pipework was run through the loft so nothing is on show. £8224 including commissioning and the F-Gas certificate. The whole upstairs stayed comfortable through the heatwave and it heats in winter as well.
