What Letchworth Homeowners Say About Our Air Conditioning Installation Specialists
Had air conditioning put into the loft-conversion bedroom in Letchworth. F-Gas registered engineer, refrigerant pipe run boxed in neatly to match the skirting, and they vacuum-tested before commissioning. £2150 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.
Needed a small office split sorting in Letchworth. The engineer was REFCOM certified and explained the F-Gas rules clearly with no hard sell. Came in at £1680 fitted, cheaper than the national chain quote. Tidy work, dust sheets down, and they took the old unit away.
Ducted system zoned for the open-plan extension in Letchworth. 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. £5400 including commissioning and the F-Gas certificate. The whole upstairs stayed comfortable through the heatwave and it heats in winter as well.
