Most homeowners know when it’s time to replace and upgrade their heating and AC systems—about every 15 to 20 years, depending on the system and maintenance care over the years. But do you know when you need to replace your thermostat? Generally speaking, the thermostat should be replaced each time the heating/cooling system is replaced. The thermostat is the primary system responsible for controlling the HVAC system—which means that the efficiency rating and size of the unit won’t matter much if its thermostat is unreliable or faulty.
As the technology for heating and cooling systems advances, so does the technology for thermostats. This means that if you’ve installed a new AC system your old thermostat might not be able to operate it as well as a newer thermostat would. Also, depending on your needs and budget, there are a variety of thermostats to choose from, including manual, digital non-programmable, programmable, wireless, learning, and communicating.
Just like the heating and cooling systems they control, as thermostats age they begin to show wear and tear and become less effective. Their efficiency decreases as it is not able to accurately detect temperature in your home, meaning the system does not heat or cool your home properly. Replacing and/or upgrading your thermostat before the AC system starts to short cycle or otherwise malfunction is the best way to prevent more serious issues from occurring and requiring an emergency service visit.
