Energy Efficiency

Allied Commercial knows the value of energy efficiency.

Lower long-term energy costs mean lower cost of ownership.

When selecting commercial heating and cooling equipment, efficiency is one of the most important points to consider. Using more energy-efficient equipment will not only help buildings stay within code and earn possible incentives for smart energy use—it will also reduce daily operating costs without sacrificing the quality and comfort of the work environment.

In heating and air conditioning, there are three main terms used to rate and compare energy use between pieces of equipment.

Seasonal Energy Efficiency Ratio (SEER)

Used to rate the energy efficiency of air conditioners, SEER is the ratio between the amount of cooling output a unit produces during a typical cooling season divided by the total amount of electricity it consumes while doing so. The higher the SEER, the more cooling is produced per watt hour of electricity, and the lower HVAC costs become during the summer. For example, our most efficient rooftop unit, the K-Series has SEER ratings up to 14.0.

Heating Season Performance Factor (HSPF)

Typically used to measure the efficiency of heat pumps, HSPF is the ratio between heat energy supplied to a building during a typical heating season compared to the amount of electricity consumed. The higher the HSPF, the less electricity is needed to deliver a set amount of heat.

Annual Fuel Utilization Efficiency (AFUE)

The efficiency of combustion-based heating equipment is measured in AFUE, which is a measure of the usable heat put off by a furnace compared to the amount of energy consumed in the process. The higher the AFUE, the less heat and fuel a furnace will waste during daily operation, and the less it will cost per season to use. Learn more about our most energy-efficient products.
