Product Lines

All Miller products are designed to heat and cool efficiently with or without a matched system. Split-system air conditioners and heat pumps range from 13 to 16 SEER and feature a small, compact size for installation on a slab or snow stand. Copeland compressors are standard components.

The company’s packaged units are also designed for outdoor installation. These systems consist of a heat pump or air conditioner or a gas/electric package unit in a corrosion-resistant, galvanized steel casing. These units offer performance up to 15 SEER.

Miller also manufactures oil, gas and electric furnaces. While AFUE ratings vary, all units are equipped with a heavy-gauge aluminized steel heat exchanger and insulated cabinets to reduce operation noise and heat loss.


Miller provides a 1-year limited warranty on parts, labor and mileage for the technician for all heating and cooling units. Packaged units are equipped with an additional 10-year warranty on compressors, while split systems have a 5-year warranty on the compressor. Furnaces have an extra 10-year warranty on heat exchangers, with a lifetime warranty available for select models.
