What Hemel Hempstead Homeowners Say About Our Air Conditioning Installation Specialists
Got a 2.6kW unit installed in the home office in Hemel Hempstead. F-Gas registered engineer, refrigerant pipe run boxed in neatly to match the skirting, and they vacuum-tested before commissioning. £2126 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.
Booked a service and re-gas for an existing split in Hemel Hempstead. The engineer was REFCOM certified and explained the F-Gas rules clearly with no hard sell. Came in at £1664 fitted, cheaper than the national chain quote. Tidy work, dust sheets down, and they took the old unit away.
Whole-upstairs cooling off a single condenser at our place in Hemel Hempstead. 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. £5336 including commissioning and the F-Gas certificate. The whole upstairs stayed comfortable through the heatwave and it heats in winter as well.
