4 Easy Tips for Thermostat Maintenance

4 Easy Tips for Thermostat Maintenance

A well-functioning thermostat is just as crucial for your HVAC system as a well-performing CPU is for your desktop computer. A thermostat is the control system behind the climatic comfort of your living space. It is a sensitive device that responds even to the slightest temperature changes. Although it contains lesser parts than the rest of your HVAC system, it can become problematic if left unchecked.


Here are some easy maintenance tips for your thermostat.

1. Get the Thermostat Tested

The only way to adjust the temperature of your house is to get your thermostat tested every fall. Here is what you need to do.

  • Place your everyday thermometer on the wall beside the thermostat. To hold it firmly against the wall, tape it. To adjust to the temperature, allow the thermometer ten to fifteen minutes. After some time, compare the reading on the thermometer with that on the thermostat.
  • If the difference between the two readings exceeds 5 degrees, make sure to have your thermostat recalibrated.

2. Anticipator Adjustment

The anticipator in your thermostat asks you to shut down the boiler or the furnace a little early. Shutting down the boiler allows the existing heat in the room to stay, thus keeping the temperature in the room at a stable level. In case, your heating system turns on and off too frequently, you may want to adjust the anticipator. If the cycles are more frequent than necessary, access the inside of your thermostat. Once you are in, reach out for the anticipator and poke the pointers high on the scale. If the cycling continues, try adjusting in another direction.

3. Thermostat Tuning

When it comes to tuning a thermostat, start by removing the cover. If the need arises, unscrew the base plate to remove it. The base plate is the one that contains all the working components of the thermostat. The thermometer inside the thermostat is a bi-metallic coil. Every time the coil heats up or cools down, it tends to expand or contract. The thermometer’s flexing strikes a switch that turns the system on or off. To recalibrate the thermometer, you will have to adjust the coil’s screws with a small screwdriver. Before fine-tuning your thermostat, make sure to go through the manufacturer’s instructions.

4. Thermostat Replacement

If the thermostat has become entirely dysfunctional and replacing it is inevitable, the below-mentioned tips will help you on the way.

  • Turn the boiler, the heater, and the AC off.
  • Remove the cover of the existing thermostat and unscrew the assembly, followed by disconnecting the wires. Remove the assembly and unscrew the plate that we discussed in the previous paragraphs. If the cables aren’t coded, code them according to the terminals they are attached to. To keep the wires from sinking back in, secure them using a pin, or tie them to a pencil.
  • Slip the wires through the new plate in the same way as they were in the previous unit. Adjust the plate on the wall and marks the holes. Secure the plate to the wall using screws and anchors.
  • If the manufacturer’s manual allows it, install backup batteries. Restore the new system and program it before using it.
