FAQ's ENVIRONMENTAL RESPONSIBILITY What should I know about changes in refrigerants? The Environmental Protection Agency (EPA), through the Clean Air Act, is regulating the production and use of refrigerants. These changes will eventually eliminate air conditioning and heat pump refrigerants containing chlorine, due to growing concern about ozone depletion. In response, Lennox has developed cooling products that use the new, chlorine-free R410A refrigerant, instead of the standard R22 refrigerant (Freon) currently in use. Because R410A contains no chlorine, it's ozone- and climate-responsible. Plus, R410 allows higher efficiencies than R22, so it not only makes sense environmentally — it also makes sense from an economic standpoint. The introduction of air conditioners with the latest in refrigerant technology reflects Lennox' proactive approach to protecting the environment. ENERGY EFFICIENCY What is two-stage heating? How can I control energy costs? Heating and cooling your home can represent as much as 44% of your utility bill. With high efficiency ratings and innovative, industry-leading technology, Lennox' home comfort systems can go a long way toward reducing these costs. When selecting a new system, pay close attention to the SEER rating of the air conditioner and AFUE of the furnace. The higher the SEER or AFUE, the higher the savings. Beyond efficiency ratings, other factors to consider are: Maintenance You can ensure your system operates at peak performance by scheduling annual maintenance checks. Call now and ask about our spring and fall check or maintenance agreement options. Zoning A zoning system can drastically lower your heating and cooling costs. With zoning, you no longer have to pay to heat or cool areas of your home that are rarely used. Programmable Thermostats According to the Department of Energy, a programmable thermostat can reduce your heating costs by up to 35% and cooling costs by up to 25%.

CENTRAL AIR AND CONDITIONING SYSTEM System in which air is treated at a central location and distributed to and from rooms by one or more fans and a series of ducts. CFM Stands for Cubic Feet per Minute. This measurement indicates how many cubic feet of air pass by a stationary point in one minute. The higher the number, the more air is being moved through the ductwork by the system. COMPRESSOR The part of the outdoor air conditioner or heat pump that compresses and pumps refrigerant to meet household cooling requirements. CONDENSER COIL The outdoor portion of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year. DAMPER A movable plate, located in the ductwork, that regulates airflow. Dampers are used to direct air to the areas that need it most. Typically used in a zoning application. DB A decibel is a unit used to measure the relative intensity of sound. DOE The Department of Energy is a federal agency responsible for setting industry efficiency standards and monitoring the consumption of energy sources. DUEL FUEL A comfort system that pairs an electric heat pump with a gas furnace, providing an energy-efficient alternative to the conventional furnace/air conditioner combination. DUCTWORK The method by which air is channeled from the furnace or the blower coil throughout your home. ELECTRONIC AIR CLEANER An electronic device that filters out large particles and bioaerosols in indoor air. ENERGY STAR An EPA (Environmental Protection Agency) designation attached to HVAC products that meet or exceed EPA guidelines for high-efficiency performance above the standard government minimums. EPA The Environmental Protection Agency develops and enforces federal environmental regulations. The EPA oversees the nationwide ENERGY STAR® program. EVAPORATOR COIL The part of the air conditioner or heat pump that is located inside the air handler or attached to the furnace. Its primary function is to absorb the heat from the air in your house. FAQ Stands for "frequently asked questions." GARAGE HEATERS Garage heaters are an excellent product for combating cold garages and workshops during the winter months. Heating capacities provide warmth for a 1 car garage up to a 4+ car garage application. Separated combustion models provide heating for hard-to-heat applications. Available in natural or propane gas, units should be installed by a Lennox dealer/installer. HEAT EXCHANGER Located in the furnace, the heat exchanger transfers heat to the surrounding air, which is then pumped throughout the home. HEAT PUMP A heat pump is an HVAC unit that heats or cools by moving heat. During the winter, a heat pump draws heat from outdoor air and circulates it through your home's air ducts. In the summer, it reverses the process and removes heat from your house and releases it outdoors. HORIZONTAL FLOW When an air handler or furnace is positioned on its side and circulates air in one end and out the other. Ideal for attic or crawl space installations. HSFP The Heating Seasonal Performance Factor is the heating efficiency rating for heat pumps. The higher the rating, the more efficient the heat pump. HSPF will be regulated in 2006 at 7.7. HUMIDIFIER An indoor air quality device that introduces moisture to heated air as it passes from the furnace into the ductwork for distribution throughout the home. HUMIDISTAT An automatic device used to maintain humidity at a fixed or adjustable set point. HVAC Heating, Ventilation and Air Conditioning. INDOOR COIL See Evaporator Coil. ISO 9000 A family of international standards for quality management and assurance. MERV RATING The MERV (Minimum Efficiency Reporting Value) rating of a filter describes the size of the holes in the filter that allow air to pass through.
