Restored 2013 information

Air conditioning

Historic air-conditioning equipment photograph from the 2013 website
Archive provenance: based on airconditioning.html (31 August 2013) and airconditioners.html (31 August 2013). It is historic editorial material, not a current offer.

The original pages explained that air-conditioning systems could provide heating as well as cooling, and treated ventilation as an important part of climate control in domestic and commercial settings.

They listed one-room and whole-house systems, air-to-water heat pumps, heat-recovery ventilation, humidifiers, dehumidifiers and mobile units. These categories remain useful context, but current suitability and standards require advice from a qualified professional.
