Comfort-Aire AHG24-0A

30,000 BTU, 1.5 to 2 Ton Cooling, Hydronic Air Handler


The AHG Series Air Handler for R-410A is equipped with a wide range of most-wanted features for dependable operation. Capacities range from 1-1/2 to 5 tons, and units are matched to 13 and 14 SEER condensers.

Units are multi-positional: they can be installed vertically or horizontal left or right. Speeding installation are a line voltage terminal block for fast wiring and a low voltage terminal strip for thermostat connections.

The cabinet is galvanized steel for durability and nylon drain pans resist corrosion. Freeze protection in both the heating and cooling modes protects the entire system year 'round.

Standard Features

  • Power: 115V-1-60 
  • Blower Time Delay—Warms the coil before the blower is energized to prevent cold air release
  • Slide-Out Blower Assembly—Makes service and maintenance fast and easy
  • 3/4" Water Connections—Assures correct water supply lines
  • Evaporator Coil—Aluminum fin/copper tube construction
  • Hydronic Coil—aluminum fin/copper tub construction with manual air vent and drain valves, compatible with water heaters and boilers
  • Factory Installed Air Filter—Disposable filters are available in standard sizes
  • TXV for R-410A included

Does Not Include Circulating Pump


Configuration is the direction the conditioned air will pass through the unit.

Upflow units will have the air come in from the bottom and blow out the top.

Horizontal units will have the air go through the unit left to right, or right to left.

Downflow units will have the air come in from the top of the unit, and blow out the bottom.

Horizontal / Upflow
Blower Cooling Capacity

The tonnage of air conditioning that can be moved effectively by the blower. You want to make sure that the blower is appropriately sized for the air conditioner. If it is too small the coil could ice up. If it is too large than the air coming out of the ducts won't be cold enough.

Maximum Heating Output BTU

The amount of heat, rated in British Thermal Units (BTUs), that the unit can deliver into the space. Not sure how many BTUs you need? Try our easy Equipment Sizing Estimator.

Maximum Heating Output BTU
30000 BTU
Nominal CFM

The amount of air that can be moved by the fan, measured in cubic feet per minute (cfm).

Nominal CFM

Inside air conditioning systems are liquid/gas refrigerant. There are two types of this refrigerant available for use, R-22 (more commonly known as Freon), and a newer alternative R-410A.

An air conditioning system does not consume refrigerant, but reuses it. As long as there are no leaks in the refrigerant circuit, there is no need to ever add more refrigerant to an air conditioning system.

Although R-22 is an effective refrigerant, if it is released into the atmosphere it can contribute to the depletion of the Earth’s ozone layer. The EPA has mandated the phasing out the use of R-22. It is being replaced by R-410A.

As of 2010, manufacturers are required to make all new air conditioners with R-410A. However, R-22 is still available for sale in existing pre-2010-manufactured equipment, and for use in servicing existing R-22 equipment. By 2020, R-22 will no longer be manufactured, but will still be recycled and available for sale.

Blower Type

There are three main type of blowers: Multi-Speed, High-Efficiency Multi-Speed, and Variable Speed.

Standard Multi-Speed blowers have different speed options and you select the speed that the blower will operate at depending on the function it is performing (ex. different speeds for fan, AC, and heating functions).

High-Efficiency Multi-Speed blowers are designed to maintain a constant torque and in doing so will maintain air-flow and use less electricity.

Variable Speed blowers will adjust their speed during operation. The result is a blower that will run at lower speeds for longer periods of time (this improves the air flow and increases electrical efficiency).
