Air conditioning for extensions and kitchen-diners in Bath
For a kitchen-diner in Bath, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.
In Bath, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Bath is about 41 miles from Taunton and falls within our Somerset coverage. That includes the BA1 postcode district.
