Coverage Area

Please refer to this coverage chart to determine the required BTUs for the area you wish to cool or heat.

  • Square Feet: Up to 400 | BTU = 9K

Note about condenser sizes versus total air handler capacity: The total capacity of the combined air handlers may exceed the capacity of the condenser in certain configurations. While this provides more flexibility in your setup, you will need to either shut off one of your air handlers (zones) or reduce the output of all zones.

FAQs

What is an AC with heat pump and why is it ideal for grow setups?

An AC with a heat pump provides both cooling and heating, allowing growers to maintain a stable environment year-round. It’s especially useful for handling seasonal shifts without switching equipment, ensuring consistent growth conditions from veg to bloom.

How do I size an AC with heat pump for my grow room?

You’ll need to factor in grow room size (cubic feet), lighting wattage, equipment heat output, and insulation. A rough rule is 3,500–5,000 BTUs per 1000W of lighting, but high-performance grows may require more. Proper sizing avoids overcooling or inefficiency.
