4 Ton Air Handlers

Airflow and heat kits for larger homes

A larger air handler must move more air, so the ductwork has to carry the CFM a 4 ton system needs. If you're adding electric heat, a bigger heat kit draws more power — confirm the air handler supports it and that the electrical panel can feed the combined load.

• Airflow — ducts sized for 4 ton CFM.
• Larger heat kit — more kW means more electrical draw.
• Electrical — panel must feed air handler plus strip.
• Match the condenser — 4 ton pairing.
