Can I Have Central Air Installed With Radiators?

Unit Size

• This consideration is the same as for a house with ducts already in place. A unit that is too small does not provide adequate cooling and costs more to operate than one that is properly sized. An oversized compressor costs more to operate because of the additional amount of electricity required to operate it. Systems with higher SEER (seasonal energy-efficiency rating) operate more efficiently.

Placement

• Most systems locate the condenser outside of the dwelling, with the fan-and-coil system located inside. For houses without a forced air system, the fan-and-coil system is usually placed in the attic. Condensers should be placed outside in areas where the airflow will not be restricted.

Installing Ducts

• Duct installation probably is the single most expensive component of the air-conditioning system. The challenge is getting ducts to properly feed second- and third-floor rooms. Contractors experienced with retrofitting older homes typically draw a floor plan to determine proper placement within a dwelling to deliver the best air flow.
