Thermostats don’t generally have a lifespan, but will usually last about 10 years, on average. If your thermostat is at least a decade old, it can start to malfunction because of the wiring or because of dust accumulation. Here are some other signs that your thermostat might not be working properly.
#1: Your thermostat isn’t showing any signs of life.
This one is obvious, but if your thermostat doesn’t have any power or is totally unresponsive when you try to turn it on or off, there is probably something wrong with it. If there is no change in the temperature of your home when you adjust the temperature on the thermostat, or if the display unit is not lighting up, check to see if batteries need to be replaced. If that isn’t the issue, it may be broken entirely and may need to be replaced.
#2: Your heater doesn’t turn on or it won’t turn off.
If your heater isn’t turning on, there could be a defect in the thermostat’s wiring that is causing an interruption in the electrical signals that are being sent to your heating system. In the same way, if your heater is running continually and won’t turn off when you want it to, this could mean there is an issue with the wiring. This should be checked out by one of our heating and cooling specialists at Hybrid Heating and Air Conditioning. If it’s not your thermostat causing the problem, it could be a problem with the heating unit itself and that requires a professional look as well.
#3: Temperature of the room and thermostat temperature do not match.
When you designate your thermostat to be 70 degrees, the temperature of the room should be 70 degrees as well. If the temps do not match, it could be a sign that your thermostat isn’t doing its job. Fluctuating temperatures throughout the house can cause your heating system to work harder than it should and could increase your energy bill. If you’re noticing that the room temperatures are colder or hotter than what your thermostat says it is, be sure to get it checked out to make sure that it isn’t faulty.
If your thermostat is old and defective, replacing it with a new programmable thermostat can be a great option. Programmable thermostats are well made and allow you to control the temperature to be exactly how you want it, even allowing you to set a time to have the heat turn back on. For example, turn down the thermostat during the hours you’re away, then program it to turn up 20 minutes before you plan on getting home. This will allow for some time for the house to warm up before you get home, so you don’t have to walk into a cold space. These thermostats are affordably priced and in the long run, they can save you money because of the energy savings associated with them.
