Some preliminary things to check

Earlier trying to diagnose anything related to air conditioning in your home, don't forget to bank check the simple stuff. It may seem obvious, simply information technology'due south likewise easy to overlook something simple and inexpensive and immediately fixate on one, big catastrophic failure that volition force yous to have out a second mortgage to fix.

Change air filters. Yous should do this every few months to begin with. Simply if you accept pets that shed and a common cold air return in a highly trafficked expanse of your home, yous might need to go on a closer centre on the filter. A clogged air filter will seriously affect your AC's ability to heat and absurd your dwelling.
Check the batteries. It may seem similar a no-brainer, only information technology's too easy to set and forget a thermostat, especially if y'all've gone through the trouble of programming it with a schedule.
Check the settings. This one is even more obvious, simply even I have been guilty of setting a temperature and not paying attention to whether the thermostat was set to heat or cool, specially in a transitional season similar leap and autumn.

The thermostat might not exist level

While virtually newer thermostats utilise some course of an electrical temperature sensor, older thermostats used mechanical switches, typically a bimetallic strip with a mercury or magnetic switch. With a mercury switch, as the temperature in the room changes, the coil expands or contracts, tilting a glass bulb with mercury within. Depending on where the mercury is inside the tube, it volition either close or open the circuit past connecting the positive and negative leads in i cease of the tube.

For this to work as intended, the thermostat needs to exist level. So break out the level and check how shut it really is. If the thermostat is circular, you may need to remove the cover and await for leveling lines or posts to ensure it'southward actually level. With a newer thermostat, beingness level is mainly for aesthetic purposes and won't affect the thermostat'southward functioning.

If y'all happen to have a thermostat onetime enough to still have a mercury seedling, information technology's probably time to consider replacing it with a newer one anyway. (Refer to our buying guide if you do!) Not only have thermostats go rather smart and more hands-off than ever earlier, the long-term savings on your energy neb will get in worth the switch.

You might need to motion the thermostat

Thermostat placement is actually very of import. It should be located in a part of the house that is most representative of the overall ambient temperature of the house and kept away from parts that face drastic temperature swings, such as doors that let in a typhoon or on a wall that gets direct sunlight in the afternoon.

A bad temperature sensor

Another cause for a thermostat to be reading the incorrect temperature in your home is a faulty temperature sensor. However, this i can be difficult to troubleshoot bated from eliminating other possible bug or only swapping out the thermostat with a new one.

When possible, try recalibrating the thermostat. This is done differently depending on what type of thermostat you have, such as a mercury or magnetic switch. Some thermostats with mechanical switches accept a calibration screw that y'all must plow until the contacts of the bimetallic strip close. Wait for a moment and turn the screw until the contacts are opened.

Also, try cleaning whatever dust inside the encompass of the thermostat with pressurized air or a pocket-size castor. If none of this works, the temperature sensor may be malfunctioning and the thermostat itself may demand to be replaced.

Get additional sensors (when possible)

Some other possibility is that the thermostat is merely too far from a room you use often, or that some rooms of your home are more sensitive to temperature shifts than others. If this is the case and your thermostat is newer (or uniform), consider either getting multiple thermostats that work in unison or satellite temperature sensors.

If you're non slap-up on wiring up multiple thermostats, you can purchase wireless thermostats that report to the main unit of measurement. Or, like with many newer smart thermostats, you tin can purchase additional temperature sensors that y'all place around the house to give the thermostat a better idea of the average temperature around the entire business firm and not simply where the main thermostat is located.
