What Horsham Homeowners Say About Our Air Conditioning Installation Specialists
Fitted a single-room split system in our south-facing lounge in Horsham. F-Gas registered engineer, refrigerant pipe run boxed in neatly to match the skirting, and they vacuum-tested before commissioning. £2933 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.
Used the form to get quotes for a bedroom unit in Horsham. The engineer was REFCOM certified and explained the F-Gas rules clearly with no hard sell. Came in at £2202 fitted, cheaper than the national chain quote. Tidy work, dust sheets down, and they took the old unit away.
Had a 4-zone multi-split installed at the house in Horsham. 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. £7488 including commissioning and the F-Gas certificate. The whole upstairs stayed comfortable through the heatwave and it heats in winter as well.
