With proper maintenance, most systems have a lifetime of 10 to 20 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier, air delivery diminishes, and it needs repairs more often. When a unit begins to show its age, you have two choices—you can overhaul the system or replace it.

Every time your system starts up, it will use a lot of electricity and not produce much cooling. Usually a system that is too small to cool the home is more economical to run but delivers less comfort. Even though a smaller unit runs nonstop, it will usually consume less power than a larger system that cycles on and off. As a rule of thumb, a unit that runs a minimum amount of time and provides adequate amounts of cooling and humidity reduction is the ideal choice.

Yes. Check to be sure that the air handler, furnace, or condenser power is on. To do this, you will need to check that the breakers and the disconnects are turned on. Also, check that the thermostat has fully charged batteries.

According to the Environmental Protection Agency (EPA), your exposure to air pollutants can be up to 100 times higher indoors than outdoors. Trane indoor air quality products handle pollutants, humidity, and other issues to improve your health.

The S.E.E.R. (Seasonal Energy Efficiency Ratio) is the amount of cooling your system will deliver per dollar spent on electricity. For example, a 3-ton unit may have a S.E.E.R. efficiency rating of 13, 14, or 15. The higher the S.E.E.R., the more efficient the system will be. The S.E.E.R. rating of any given unit can range anywhere from 10 to 25 depending on the type of system.
