Air Coils are devices for transferring heat from the agent inside the coil to the surrounding air, or vice versa. They are composed of thin tubes of metal with sheets of metal bonded to them (fins) and are filled with steam, water or refrigerant. Air coils may be installed in air handlers, furnaces, ducts or plenums.
Air Coils can be used in forced air HVAC systems, variable volume or constant volume HVAC systems or in any HVAC system which requires air to be re-conditioned before reaching any grilles, registers or diffusers.
Tips on Estimating Air Coil Costs from RSMeans
 | Review all construction documentation before proceeding with the estimate for HVAC. It is not unusual to find items on the plans, but not in the specifications; or they may be in the specifications but not on the drawings. Also check any and all communications; the owner may have requested a change or expressed a concern or a specific need, and not have had it included in your drawings or specifications. |
