Resources

  • Air Handler
    An air handler, or air handling unit, is the indoor part of an air conditioner or heat pump that moves cooled or heated air throughout the ductwork of your home. It is usually a large metal box containing important elements of an HVAC system that controls airflow and filtration. Lennox® air handlers are among the most efficient and quietest you can buy.

  • Central Air-Conditioning

    Developed in the 1960s, central air conditioning or central AC is the most common type of whole-home HVAC system used in the United States today. A central AC system’s job is to cool air in a central location and distribute it evenly throughout a home or other multi-room space. This centralization eliminates the complications of cooling each space separately while maximizing efficiency and comfort.

  • Compressor
    An AC or heat pump compressor is the part of an outdoor air conditioner or heat pump that compresses and pumps refrigerant to meet household cooling requirements.
    Learn More
  • Condenser
    A condenser (or AC condenser) is the outdoor portion of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year.
    Learn More
  • Decibel (dB)
    A decibel (dB) is a unit used to measure the relative intensity of sound. For example, sound levels in a library are normally about 40 dB, normal conversations range from about 50 to 60 dB, and an operating motorcycle or garbage truck can be as high as 100 dB.
    Learn More
  • Dry-Charged Unit
    An air conditioner or heat pump that is shipped dry and charged with refrigerant at the place of installation. Dry-charged units are appropriate for homeowners who need a replacement unit compatible with R-22 refrigerant.
    Learn More
  • Dual-Fuel
    A comfort system that pairs an electric heat pump with a gas furnace and alternates between the two fuel sources to maximize comfort and efficiency.

  • Energy Star®
    ENERGY STAR® is a program of the U.S. Environmental Protection Agency (EPA) designed to help consumers and businesses save money by choosing energy-efficient products and technologies. Heating, ventilation and air-conditioning (HVAC) equipment with the ENERGY STAR® label meets or exceeds federal guidelines for energy-efficient performance.

  • Grid-Tie Inverter Solar System
    A grid-tie inverter solar system is the most common and least expensive of all residential solar systems. It allows homeowners to 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.
    Learn More
  • Heat Pump
    A heat pump is an HVAC unit that heats and cools by extracting and transferring heat. Unlike traditional air-conditioners, heat pump systems have the ability to both cool a home during the summer months and heat it during winter. They do this through a reversible refrigerant cycle within the system. During cold weather, a heat pump extracts from outdoor air and transfers it inside to warm the home. This same process is reversed during warm weather for cooling, with the heat pump extracting heat from inside and transferring it outside.
    Learn More
  • Heating Seasonal Performance Factor (HSPF)
    The heating efficiency rating for heat pumps. The higher the rating, the more efficient the heat pump.
    Learn More
  • Net Metering
    A service available from many utility providers in which homeowners get full retail value for most, if not all, of the electricity produced by their own generating system. A utility meter keeps track of the “net” difference between the electricity used from the utility provider and the electricity produced by the homeowner’s system.
    Learn More
  • Off-Grid Or Off-The-Grid
    An off-grid or off-the-grid system is an electricity-generating system that operates independently from the utility grid, providing all of the electricity needed in the home, and is generally more expensive than grid-tied system ideal for homes located in remote areas without utility service, or where installing power lines would be extremely costly.

  • R-22 Refrigerant
    The old standard for residential air conditioners, now being phased out by the U.S. EPA. Lennox offers dry-charged units for those who still have R-22 compatible systems.

  • R-410A Refrigerant

    R-410A, is a chlorine-free, hydrofluorocarbon (HFC) refrigerant originally developed as a more environmentally friendly replacement for R-22. R-410A was developed and patented in 1991 by Honeywell.

  • Refrigerant

    Refrigerant is the working fluid used in air conditioners, refrigeration, and heat pump systems. It is a chemical compound that changes temperature as it transitions between liquid and gas form – cooling as it vaporizes, and heating up as it condenses. It is this property that facilitated a system’s ability to heat and cool.

  • Refrigerant Lines
    Two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil.

  • Scroll Compressor
    A specially designed compressor that works in a circular motion, as opposed to up-and-down piston action.

  • SEER

    Simply put, this rating measures how much energy a heating and cooling system uses to operate. Learn how you can use SEER and SEER2 ratings to increase efficiency – and savings – in your home.

  • SilentComfort™ Outdoor Fan Motor
    Describes a motor with electronic sensor technology that helps optimize overall system performance while keeping sound levels low. Used in select Lennox® outdoor air conditioners or heat pump units.

  • Variable Speed Motor
    A motor that operates at a wide range of speeds to precisely control the distribution of heated and cooled air throughout the home.

  • * Efficiency claim based on comparison of air conditioning and heat pump products' SEER as published in AHRI (January 2015). Actual system combination efficiency may vary; consult AHRI for exact system efficiencies. Precision claim based on the cooling capacity range of the XC/XP25-036 units as compared to equivalent-sized competitive variable capacity compressor units.
Energy Star

Proper sizing and installation of equipment is critical to achieve optimal performance. Split system air conditioners and heat pumps (excluding ductless systems) must be matched with appropriate coil components to meet ENERGY STAR criteria.
