What’s in this rate
This unit is installing one electric reheat coil in a duct or terminal coil section. The HVAC technician sets the coil, connects the duct and local electrical leads as furnished, and leaves it ready for controls and checkout. The rate is per each electric reheat coil. Hot-water reheat coils, VAV reheat coils, and power wiring beyond the coil lead are separate units.
Includes
- electric reheat coil (class mid)
- duct / terminal connect allowance
- local lead connection share
- set and leave controls-ready
- small tools
Excludes
- hot-water reheat coil (see hot-water-reheat-coil)
- VAV reheat coil (see vav-reheat-coil)
- power wiring beyond coil lead
- BAS beyond coil lead
- TAB
What is an electric reheat coil?
An electric reheat coil is a set of resistance heating elements mounted in a duct or on a terminal unit. It warms supply air that the central system has already cooled, so each zone can hold its own temperature, and it helps control humidity when air is overcooled to dry it out. Unlike a hot-water reheat coil, it needs no piping, boiler or valve, only power and controls. A VAV reheat coil is the same idea built onto a variable air volume box.

Questions
What does a reheat coil do in an HVAC system?
A reheat coil adds heat back to cooled supply air just before it reaches a room. Central air handlers often cool all air to one temperature, which can leave lightly loaded zones too cold. The reheat coil trims each zone back up to its setpoint and lets the system dehumidify without overcooling the occupied space.
When is an electric reheat coil chosen over a hot-water coil?
Electric coils make sense where there is no heating hot water nearby, where zones are few or spread out, or where running piping would be costly or disruptive. Hot-water coils are common in buildings with a central boiler plant. Electric coils need an airflow proving device and a power circuit, which the electrical trade usually carries separately.
