Signs I Need to Replace My Air Conditioner’s Thermostat

My Father’s Mechanical can replace the thermostat in your home when it needs it. We are going to list the signs of a faulty thermostat below so you know what to look for in your house. The sooner you replace the thermostat the better for the air conditioning unit. You don’t want the unit overworking or underworking. This puts undue strain on the air conditioner and could cause it to malfunction.

The HVAC Unit Short Cycles

One sign that the thermostat has gone bad is if your air conditioner or heater short cycles. What we mean by this is that the unit turns on and off constantly. There should be a break between the time that the air conditioner turns off and turns on the next time. If the unit is continually running or turns on quickly after it has shut down, the thermostat could be the problem.

Incorrect Thermostat Readings

Another sign that you need to replace your thermostat is if the thermostat is producing incorrect temperature readings. For example, your home may be warm but the thermostat may say it’s 50 degrees inside. This is definitely a sign that the thermostat is malfunctioning. In fact, your house may get too hot because the air conditioner may never turn on due to the faulty reading.

Excessively High Energy Bills

If you have opened your electric bill and been shocked by how high it is, this, too, can be a sign that the thermostat is not working correctly. Your energy bill is going to increase if the air conditioner is short cycling. The more the air conditioner runs the more energy it uses. Consequently, a malfunctioning thermostat can increase your energy bill significantly until you have it replaced.

Constant Temperature Changes

You may also notice that the temperature in your home changes constantly. This is an indication that the thermostat is malfunctioning and failing to turn on the air conditioner at the right time. Your home’s interior should remain at the set temperature on the thermostat consistently.

Failure to Respond to Changes

Finally, a malfunctioning thermostat will not respond to temperature changes. For example, if you suspect that your thermostat has gone bad, turn it up or down to see if the air conditioner turns off or on, respectively. If nothing happens, the thermostat is not responding to your temperature change.
