When Should I Replace My Thermostat?

Your thermostat is the brain of your HVAC system, regulating the temperature inside a single room or your entire living space. It works by sensing the ambient temperature and sending an electrical signal to your air conditioning system, furnace, or both, causing it to cycle. Thermostats are fairly reliable devices, but they occasionally run into problems just like any other component of your system. But how do you know when it’s time to replace your thermostat?

You Have an Older Thermostat

Thermostats were once only mechanical, and relied on a glass tube filled with mercury to operate. These devices are not as reliable as today’s digital units and over time these thermostats wear down and the glass can break, spilling mercury. Today’s digital thermostats hold room temperatures within a comfortable range more accurately. If you do choose to replace your mercury thermostat, be sure to inquire about proper disposal.

You Experience Temperature Swings

When a thermostat malfunctions, you’ll likely notice uncomfortable swings in room temperature. Your living space can be too cold one minute, but way too hot the next. This means your thermostat is unable to correctly sense the room’s temperature, or it is feeding incorrect information to the furnace or air conditioner regarding cycling times.

You Have the Incorrect Thermostat

Are you using the right thermostat for your HVAC system? Homes with heat pumps might not benefit as much from having a programmable thermostat due to the energy required to fluctuate home temperatures after the system has been turned off for a period. Your thermostat should be designed specifically for your type of HVAC system.

Having the correct thermostat installed is one of the most cost-effective ways to increase your home’s efficiency. Thermostats on the market today use advanced technology to help you maintain consistent and reliable temperatures in your home.
