You may notice that your home is suddenly too hot or too cold. Perhaps the fan runs constantly, but the temperature gauge does not register a change. This could be a sign of aging equipment or could simply be the fault of the thermostat.
If your heating and air conditioning unit is more than fifteen years old, you may certainly be looking at replacement. First, though you should look at the options. Before troubleshooting your thermostat, check to see if all filters are clean and all hoses to and from the units themselves are free of wear.
If these are not causing problems, then it is time to look at specific issues and possible solutions. Your thermostat could have aging wiring that is faulty or the transformer may require replacing.
Always check the owner's manual for the system first, if it is available.
For a wireless system, make sure you are using the correct batteries: AA Lithium. If the system is running at inconsistent times, then you may have inadvertently installed alkaline batteries. Regular batteries will run out of juice quickly in a wireless system, especially if the backlight is on or used frequently to check the readings.
