A heating and cooling air conditioning system includes serially arranged conductive and evaporative pad heat exchangers through which circulating air to be heated or cooled is moved by a blower. The conductive heat exchanger contains a liquid heat exchange medium that is selectively solar heated or cooled by an evaporative heat exchanger, for example, a cooling tower. A single tank reservoir is provided for the heat exchange medium. A singular air valve controls flow of air into the heat exchangers as well as flow of return air to exhaust. A domestic hot water heating tank is disclosed with a heat exchange loop provided in the solar heated heat exchange medium reservoir tank for heating the service hot water supply.
