Air conditioning for extensions and kitchen-diners in Horncastle
In Horncastle, a side wall of a single-storey extension is usually the neatest place for the indoor unit. In the East Midlands, one system that cools in summer and heats efficiently in winter makes good use of the investment.
An extension in Horncastle with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Our Lincolnshire coverage takes in Horncastle, about 17 miles from Lincoln. Coverage includes LN9.
