As a Lake Bluff, IL, homeowner, you probably take HVAC system maintenance seriously. You may know how to replace your air filters and check the condensate line, but what do you do when your thermostat stops working? Let’s take a look at some troubleshooting tips to help you decide when to call in the pros to fix a malfunctioning thermostat.

Check for Power

For digital thermostats, replace the batteries to ensure the proper voltage supply to it, unless it’s hardwired. Check for loose or frayed wires, and look over your breaker box to ensure a breaker isn’t tripped. An HVAC maintenance plan may catch issues like loose wiring and poor electrical connections before they develop into big problems.

Check the Settings

If your heater or air conditioner isn’t starting, check to make sure you have yit set correctly. It’s a good idea to set the thermostat to room temperature plus or minus 5 degrees, so there’s enough of a temperature differential for it to engage the system.

Clean the Thermostat

Periodic cleaning of mechanical thermostats aids in proper operation. When it get dirty, the interior parts don’t react like they should. When these parts hang up, it stops working.

Mismatched Thermostat

A thermostat mismatch most often occurs when a homeowner attempts a do-it-yourself replacement. For correct and efficient operation, thermostats must match the system they are managing. A poor match can lead to increasing utility costs, short cycling and potential system failure.

Improperly Located Thermostat

The location of your home’s thermostat is critical to system performance. If it’s placed in direct sunlight or in rooms with lower ventilation may not provide an accurate temperature reading, causing your system to run too much or too little.

If it has stopped working or if you worry about it impacting the performance of your HVAC system, you owe it to yourself to call in a professional technician. Call us at Ireland Heating & Air Conditioning Co. to install a high-quality Carrier programmable thermostat.
