HVAC energy efficiency is an important topic to understand as you make decisions regarding your home’s heating and cooling system. There are a multitude of factors and ratings that go into determining and describing energy efficiency. As always, our goal is to help reduce confusion so that you, the customer, have the knowledge necessary to make important decisions. First we’ll focus on describing the various energy efficiency ratings. Then we’ll dive into the parts of your system that most affect efficiency. Finally, we’ll reference our main units and how they rate within energy efficiency.
Energy Efficiency Ratings
When considering a new system, you want to look at its energy ratings. The higher the rating with each of these, the better the system will run. In other words, a higher number means a system will use less energy to heat and cool your home.
SEER– this stands for Seasonal Energy Efficiency Ratio and is for air conditioners. Again, the higher the SEER number, the more efficient the unit. The current highest SEER in the Daikin line is 23, with other units coming in at 12 or above.
AFUE– this stands for Annual Fuel Utilization Efficiency and is relevant to gas furnaces. AFUE is a percentage that shows how much the furnace’s energy source is converted to heating, with the rest being lost to exhaust. So then, a higher percentage means less energy lost. Side note: an electric…
