How Important Are Energy Efficiency Ratings in Your Decision?
Energy efficiency ratings are crucial when selecting the best brand of furnace and air conditioner, as they directly influence operational costs and environmental impact.
- Seasonal Energy Efficiency Ratio (SEER): This rating measures the cooling output of an air conditioner during a typical cooling season divided by the total electric energy input during the same period.
- Annual Fuel Utilization Efficiency (AFUE): This rating indicates how efficiently a furnace converts fuel into heat over the course of a year, expressed as a percentage.
- Energy Star Certification: Products bearing this label meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency, indicating superior performance compared to non-certified models.
