Heating, Ventilation and Air Conditioning TerminologyThe HVAC LingoQuick Links [AFUE] [BTU] [CFM] [Energy Star] [Heat Pumps] [SEER] [Single Stage / Single Speed] [Temperature Zoning] [Ton] [Two-Speed / Two-Stage] [UV Treatment] [Variable-Speed]AFUE - Stands for Annual Fuel Utilization Efficiency. Think of it at miles per gallon in the furnace industry. Our furnaces range from 80% AFUE to as high as 96.6%. This means that only 4 to 20 cents goes out your exhaust opposed to 40 to 50 cents with older heating systems. BTU - Stands for British Thermal Unit. For heating, it is the measure of heat given off when fuel is combusted. For cooling, it is a measure of heat extracted from your home. One BTU is equal to the amount of heat given of by a single wooden match. CFM - Stands for cubic feet per minute. This is the amount of airflow that flows through your system. When using air conditioning the rule of thumb is 400 CFM per ton of air conditioning. For example a 4 ton system has to have a duct system capable of delivering 1600 CFM of airflow. Energy Star - Is a program of the U.S. Department of Energy and Environmental Protection Agency. It is designed with the purpose of helping consumers identify energy efficient products. We are proud to be part of the energy star program and offer many products that meet their standards. Heat Pumps - If you only use electricity to heat your home and have to gas then a heat pump is what you need. Heat pumps provide up to three times more heat than the energy they consume! They also double up as an air conditioner too. A heat pump is capable of reducing the amount of electricity you use to heat your home by up to 40%. SEER - Stands for Seasonal Energy Efficiency Ratio. The minimum SEER rating today is 13 SEER and we offer products upwards of 19 SEER. Older cooling systems can be as low as 5 SEER. In this case you can save 30%-70% on your cooling bill by replacing it with a more efficient system. Single Stage / Single Speed - This means that the unit is designed to perform at its highest heat mode. Furnaces are always designed to be able to heat your home on the coldest day. The problem with this is that you only need this heating capability a few days of the year. Single speed furnaces do not have the capability to adjust to milder conditions, this causing high temperature swings, a less comfortable living environment and increased energy usage. Temperature Zoning - Ton - It is a measurement used to determine heating and cooling capacity. In cooling, one ton equals 12,00 BTU. This meaning a 3 ton system would be capable of delivering 36,00 BTU per hour. Two-Speed / Two-Stage - The unit is capable of performing at two heating stages. This greatly improves on indoor air circulation, overall comfort and also reduces operating noise. It operates on the lower speed over 90% of the time, which saves the consumer money on fuel and electricity. It only performs at high heat mode when there is a big demand for heat. This creates an overall more comfortable home with less temperature swings that are often associated with single speed furnaces. UV Treatment - Variable-Speed - Variable speed furnaces offer the quietest most efficient technology on the market today. The blower motor uses only 1/8 of the power of a standard furnace and has the ability to ramp airflow up and down based on temperature demand resulting in maximized home comfort. This furnace is especially effective for those who suffer from high-energy bills or for those with air filtration needs; such as allergy sufferers, pet owners, and those with dust problems. Using this furnace also increases air conditioning efficiency 10%. | |
