Advanced Reciprocating Compressor – Type of compressor that uses a more efficient process for compressing refrigerant for better cooling efficiency.
AFUE – Annual Fuel Utilization Efficiency. Your furnace’s AFUE tells you how much energy it is converting to heat. For example, an AFUE of 90 means that 90% of your fuel is warming your home while the other 10% escapes with combustion.
BTU – British Thermal Unit is a measurement used for both heating and cooling. BTU’s are the heat given off while consuming fuel. One BTU equals the heat given off by one wooden kitchen match.
Capacity – The ability of a heating or cooling system to heat or cool a given amount of space. For heating, it is usually expressed in BTU’s. For cooling, it is usually given in tons.
CFM(Cubic Feet per Minute) – A measurement of cubic feet of air passing by a stationary point in one minute. The higher the number, the more air the system is moving through the ductwork .
Downflow – A type of furnace that takes cool air from the top and blows warm air to the bottom: common when the furnace is located in a second-floor closet or utility area.
Electronic Air Cleaner (EAC) – An electronic device that filters out large particles and indoor air contaminants. It also electronically pulls out tiny particles that are magnetized, such as viruses and bacteria, drawing them to a collector plate.
Energy Star® – A designation of the U.S. Environmental Protection Agency(EPA). Attached to HVAC products that meet or exceed federal guidelines for energy-efficient performance.
Evaporator Coil – Part of a split-system such as air conditioning or heat pump. Located indoors, the evaporator coil cools and dehumidifies the air by converting liquid refrigerant into a gas, absorbing the heat from the air. The warmest refrigerant is then carried through a tube to the outdoor unit(condenser coil).
Fan Coil – An indoor component of a heat pump system, used in place of a furnace; providing additional heating on cold days when the heat pump does not provide adequate heating.
Grid-Tied System – The most common of all residential solar systems. Homeowners use their own solar-generated electricity to save energy and reduce costs. The utility company’s grid, or network of power stations, serves as the backup power source.
HSPF – The Heating Seasonal Performance Factor is a measure of the heating efficiency of a heat pump. The higher the HSPF number, the more efficiently the heat pump heats your home or business.
Humidifier – A piece of equipment that adds water vapor to heated air as it moves out of the furnace, adding many advantages including providing adequate moisture to protect furnishings and reduce static electricity.
HVAC – Heating, Ventilation and Air Conditioning.
Load Estimate – A series of studies performed to determine the heating or cooling requirements of your home. An energy load analysis uses information such as the square footage of your home, window and door areas, insulation quality and local climate to determine the heating and cooling capacity needed by your furnace, heat pump or air conditioner.
Matched System – A heating and cooling system composed of compatible products certified to guarantee a high-level of comfort and efficiency when used together and in accordance with design and engineering specifications.
MERV Rating – The Minimum Efficiency Reporting Value is the standard comparison of the efficiency of an air filter. The MERV scale ranges from 1(least efficient) to 16(most efficient), and measures a filter’s ability to remove particles from 3 to 10 microns in size.
Micron – A unit of measure equal to one millionth of a meter, or one thousandth of a millimeter.
Operating Cost – The day-to-day cost of running your home comfort equipment, based on energy use.
Payback Analysis – Overall measure of the efficiency and value of your home comfort system. By combining your purchase price and ongoing operating costs, a payback analysis determines the amount of years required before monthly energy savings offset the purchase price.
Reclaiming – Returning used refrigerant to the manufacturer for disposal or reuse.
Reciprocating Compressor – A type of compressor used in air conditioners that compress refrigerants by using a type of “piston” action.
Recycling – Removing, cleaning and reusing refrigerant.
Scroll Compressor – A specially designed compressor that works in a circular motion, versus up and down “piston” action.
Setback Thermostat – A once state-of-the-art(now standard) electronic thermostat with a built-in memory programmed for different temperature settings at different times of the day.
Split System – Refers to an air conditioner or heat pump that has components in two locations. Usually, one part of the system constitutes the evaporator coil(inside) and the condenser coil(outside).
Thermostat – Device that monitors and controls HVAC system products. Once only available in analog, new, optional wireless thermostats are accessed directly from your smart phone or computer from anyplace at anytime.
Ton – A unit of measure for cooling capacity. One ton=12,000 BTUs per hour.
Total Home Comfort System – The ultimate solution to providing you with consistent, customized home comfort, despite the ever-changing weather.
Two-Stage Operation – Provides two levels of heating or cooling output for enhanced temperature control, energy efficiency and indoor air quality.
Upflow – A type of furnace that draws cool air from the bottom and blows the warmed air out of the top into the duct work. This type of furnace is usually installed in a basement or a utility closet.
Variable Speed Motor – A motor that operates at a wide range of speeds to precisely control heated and cooled air distribution throughout the home.
Ventilator – A ventilator captures heating or cooling energy from stale indoor air and transfers it to fresh incoming air.
Zoning – A way to increase your home comfort and energy efficiency by controlling when and where heating and cooling occurs in a home. Programmable thermostats control operating times of equipment while dampers direct airflow to certain areas, or “zones” of the home.
