"Indoor air quality," or IAQ, is a relatively new topic in environmental safety. While a lot of attention has been placed on outdoor pollution over the past few decades, the focus on indoor air quality is just beginning. The quality of a home's air mainly has to do with the amount of pollutants inside, but it's also determined by humidity and ventilation levels. The U.S. Environmental Protection Agency has found that concentrations of pollutants can be up to 100 times higher indoors than outdoors.
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:
Refrigerants are what make air conditioning possible. Contained within the coils of an air conditioner, these liquid agents cool and dehumidify indoor air. For years, the most common refrigerant used in air-conditioning systems was R-22. In response to growing environmental concerns, production of systems using R-22 refrigerant is being phased out. Lennox has led the way in the manufacture of cooling systems that use chlorine-free R-410A refrigerant. Because R-410A contains no chlorine, it is considered ozone-friendly.
What's worse than freezing your keister off on when Old Man Winter blows through town? Freezing in your own home. The trouble is, those pesky heating costs can really pile up. The largest expense in the average U.S. home is space heating, which accounts for about 45 percent of annual energy bills. Households that use natural gasspend about $700 a year on heating costs, while the price tag for those who rely on oil to keep their houses and apartments cozy is a whopping $1,700 annually.
The thermostat, a heat-sensitive switch, is the basic control that regulates the temperature of your home.
It responds to changes in the temperature of the air where it is located and turns the furnace or air conditioner on or off as needed to maintain the temperature at a set level, called the set point. The key component of the thermostat is a bimetallic element that expands or contracts as the temperature increases or decreases in a house.
