Calculating a furnace’s energy costs requires considering both the gas it burns and the electricity it consumes to run its blowers and controls.
How efficiently a furnace convert’s gas into heating energy is reflected in its (AFUE) annual fuel utilization efficiency rating, which is measured as a percentage. The higher that percentage, the more heat the furnace can provide.
Today, the most efficient models have an AFUE of about 96% and the lowest efficiency allowed by law for new gas furnaces is 78%.
Central air conditioning is a system that cools one or more rooms in a house or building. An air-conditioning system blows cooled air through duct to deliver it throughout the interior rooms. This differs from a portable room or window air conditioner, which is meant to cool only a single room. Air conditioners use refrigeration principles to cool the air. To do this job, a condenser, compressor and evaporator work together. Air conditioners may look alike, but check the SEER ratings (Seasonal Energy Efficiency Ratio). A 13 SEER rated air conditioner uses 20-23% less energy then a 10 SEER unit. 13 SEER will be the minimum efficiency standard by 2006. R-22 is the most common refrigerant used in air conditioning systems. Starting in January of 2010 manufactures will no longer be able to use R-22 in any newly manufactured Air Conditioning units. The new refrigerant, ozone friendly R-410, will replace the R-22.
Today's commercial air conditioning units have come a long way from older models both in technology and design. Modern HVAC systems built to handle the heavy requirements of commercial buildings are typically installed outside on the roof. To keep the outdoor elements from hampering the system's efficiency, heavy layers of insulation are added to the ducts and interior walls. This insulation makes today's high-tech systems better able to operate when the condenser is located outside.

Heating water typically consumes from 10% to 15% of a home’s total monthly energy budget. There are three common types of water heaters used in homes: storage water heaters, tank less on-demand water heaters, and instant hot-water dispensers. Storage water heaters heat water with natural gas or electricity and hold the heated water until it’s needed. Tank less on-demand water heaters very popular alternative, because they save energy by heating water as it passes through, eliminating the need for storing water at a high temperature. The third category, instant hot-water dispensers are point-of-use water heaters typically used at the kitchen sink.
