Knowing what a good SEER rating of an air conditioner is essential. You can use this calculator below to calculate the yearly electricity cost for every air conditioner. We predispose the 1,000h/year operation use and 13,19 cent per kWh to calculate the electricity bill based on BTU and ...
Furnace AFUE:This represents the percentage of heat that is transferred into the ducts. Boiler AFUE:Ina boiler, most of the heat is passed into water circulating through the equipment. Some heat is lost out the exhaust vent. The hot water carries the heat through pipes to radiators where th...
A higher EER2 rating means your air conditioner is more energy efficient — and that’s a good thing! An energy-efficient AC will save you money on your utility bills and leave a small carbon footprint in the process. What is EER2?
HVAC stands for heating, ventilation, and air conditioning – the systems that work together to keep your home a comfortable temperature and improve air quality.

The Energy Star program also provides a performance rating factor for heat pumps since those units, unlike straight air conditioning systems, operate through both heating and cooling seasons:Heating Seasonal Performance Factor (HSPF): This is a measure of a heat pump's energy efficiency over one ...
The thermostat device is a part of the AC system that helps to control the degree of temperature in the room. Heat Seasonal Performance Factor (HSPF) Heat Seasonal Performance Factor is a rating that is based on the efficiency of a heating system. It compares the amount of heat produced dur...
Starting Jan. 1, 2023, the Department of Energy will require all split system heat pumps to have an HSPF2 rating of 7.5 or higher, and all single-packaged heat pumps to have an HSPF2 of 6.7 or higher. The best HSPF2 rating for your heat pump depends on a number of different factors...
