Signs It’s Time for Thermostat Replacement

If it’s time for thermostat replacement, will you recognize the warning signs? Thermostat malfunctions may be very conspicuous or they may be quite subtle, like simply poor efficiency and diminished indoor comfort. While a few DIY fixes may remedy simple problems, thermostat replacement is usually the more cost-effective way to deal with major malfunctions. In many cases, it’s also an opportunity to upgrade to a more advanced, digital thermostat, as well.

Here are some common issues that may warrant thermostat replacement:

  • Thermostat actuates at wrong temperature. If your thermostat activates the A/C or furnace at some temperature other than the one it’s set for, the thermostat sensor is out of calibration or defective. Some units have an adjustment that allows you to adjust thermostat calibration by plus or minus 5 degrees. However, if the difference between the thermostat setting and the temperature where it actuates is more than 5 degrees, replacing the thermostat is the only option.
  • Rapid on/off cycling. Temperature changes caused by a nearby exterior door opening and closing, or exposure to direct sunlight, may turn the HVAC system on and off too frequently. Relocating the thermostat may help. An over-sized furnace or A/C may cycle frequently, as well. If neither of these explanations applies, the issue is almost certainly thermostat-related and replacement is indicated.
  • Functions run nonstop. If the Heat or Cool functions stay on continuously without cycling off, first make sure the thermostat is set to Auto and the desired thermostat temperature setting is correct. If those check out, replacing the thermostat is probably the right call.
  • Thermostat is obsolete. An outmoded manual thermostat is a throwback to a bygone era of cheap energy and less convenience. The price of a new digital programmable thermostat will be compensated by lower monthly heating/cooling costs in the first year of operation. The user-friendly features offered by a digital model are also a vast improvement over the old-school manual model.
