Buyer's Guide

Energy Efficiency

Keeping your home at a consistently comfortable temperature uses a lot of energy. In fact, home heating and cooling typically accounts for more than half of your monthly utility bill.* So, if you want to save money on energy costs, choose the most energy-efficient HVAC system that suits your home and budget.

Efficiency ratings

High-efficiency units use less energy to deliver the same amount of heating or cooling as standard-efficiency equipment. Different terms are used to describe the energy efficiency of different types of units, but the idea is basically the same: The higher the efficiency rating, the more energy—and money—you’ll save.

Air Conditioner Efficiency

The efficiency of an air conditioner is measured in Seasonal Energy Efficiency Ratio (SEER). The U.S. government sets minimum levels at 13.0 SEER, but for energy efficiency and significant utility savings, Allied offers air conditioners with up to 16.0 SEER.

Furnace Efficiency

AFUE, or Annualized Fuel Utilization Efficiency, is a measure of a furnace’s efficiency. AFUE ratings can vary from 80% all the way up to 98%. Some states and provinces have their own local rules about minimum efficiency requirements, and US and Canadian guidelines differ.

Heat Pump Efficiency

Heat pumps are an ideal source of heating and cooling for homes in milder climates. For that reason, heat pumps have both a SEER rating (for cooling efficiency) and a Heating Seasonal Performance Factor (HSPF) rating (for heating efficiency). Allied™ heat pumps range from 13.0 SEER and 8.0 HSPF, all the way up to an extremely efficient 16.0 SEER and 9.5 HSPF.
