Air conditioning and heat pumps

Air conditioning and heat pumps

Air conditioning, or cooling with heat pumps uses significant amounts of electricity and requires the home to be closed off from the outside environment to work best.

It dries the internal air and can harbour and spread bacteria if not maintained.

If passive design principles are followed and some supplementary cooling is still required, other options such as fans are much more cost effective than air-conditioning. Even if you  heat pump is very energy efficient, you will find your power bills going up if you use it for summer cooling.
