The stratospheric ozone layer shields the Earth from the sun’s harmful ultraviolet radiation. Emissions of certain synthetic chemicals—including CFCs, halons, and HCFCs—destroy the ozone layer, and have created an “ozone hole” over the South Pole.
If your old air-conditioning system seems to be costing more to operate than it did past summers, yet your home still isn’t quite comfortably cool, it may be time to think about investing in a newer system. The question is what is the right size to buy?
The SEER measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame.
Knowing how to troubleshoot an air conditioner often starts with the main control – its thermostat. Thermostats come in a variety of options, starting with very basic models that simply control heating and cooling temperatures and fan operation.
Running your air conditioning system can account for a significant cost during the summer. Nearly half of your average electric bill is spent on cooling your space.
