EER stands for Energy Efficiency Rating. It is a rating system to determining how efficient an air conditioner or heat pump is. It simply uses a formula to determine how much power (electricity) it takes to product a certain amount of cooling (BTUs) at a specified set of conditions. (Technically you can’t produce cooling, [...]
The difference between SEER and EER is the “S”. The “S” stands for Seasonal. The EER is determined at a specific set o conditions. The SEER takes into account the different conditions that occur throughout the cooling season. EER was one of the original efficiency rating system used. Now, SEER is the more commonly [...]
HSPF stands for Heating Seasonal Performance Factor. Simply put, it rates how efficient a heat pump is during the heating season. How much heat is generated divided by how much electricity is used. The higher the rating the more efficient the system.
AFUE stands for Annual Fuel Utilization Efficiency. It is a way of determining how efficient a furnace is. When a furnace burns fuel, most of the heat is captured and distributed through the home or building. However, some of the heat also escapes through the vent pipe. Most furnaces installed in the south have [...]
Any furnace with an AFUE rating of 90% or higher is considered a condensing furnace. That is because so much of the heat is removed that the exhaust gases actually cool and condense in the vent pipe. That means that the air going up the vent cools down to the point where it meets [...]
