1. How does an air conditioner work?
An air conditioner seems as if it cools your home's air, but it actually makes your home less warm by removing heat from the indoor air and transferring that heat to the outdoor air. Heat is extracted from the home by passing indoor air across a refrigerant coil in the indoor unit. Refrigerant lines then carry the heat to the outdoor unit, where it is released into the outside air. The cooling cycle continues until the indoor temperature reaches the thermostat setting.
2. What is a heat pump?
A heat pump is an all-in-one heating and air conditioning system that works year-round to keep you comfortable. During warmer months, a heat pump works as a normal air conditioner. It extracts heat from inside the home and transfers it to the outdoor air. In colder weather, however, the process reverses - the unit collects heat from the outdoor air and transferring it inside your home. Even when the air outside feels extremely cold, the air still contains some heat. The heat pump pulls the heat
3. How should I zone my house?
A zoning system is designed for the many ways you use your home. Maybe you're caught up in family "thermostat wars"? Or perhaps you have unoccupied areas that do not need conditioning? A Lennox¨ zoning system allows you to divide your home into separate areas, giving you the comfort and control you've always wanted.
4. What is two-stage cooling?
Two-stage cooling means the air conditioner or heat pump has a compressor with two levels of operation: high for hot summer days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures. Longer cooling cycles also translate to quieter, more efficient operation and enhanced humidity control. Compared to a single-stage unit, a two-stage air conditioner or heat pump can
5. What is variable speed technology and how does it apply to air conditioners?
"Variable speed" refers to the fan motor inside the air handler - the indoor part of an air conditioner that moves cooled or heated air throughout the ductwork of your home. An air handler is usually a furnace or a blower coil. Unlike conventional single-speed motors, a variable speed motor runs at a wide range of speeds to precisely control of heated and cooled air throughout the home.
6. What do all those air conditioner and heat pump ratings mean?
SEER (Seasonal Energy Efficiency Ratio) is a system for rating the efficiency of cooling equipment. The higher the SEER rating, the less your unit will cost to operate. HSPF (Heating Seasonal Performance Factor) is a measurement similar to SEER, but it measures the efficiency of the heating portion of a heat pump.
