The AC thermostat is the basic interface between you and your HVAC unit.
This component monitors indoors temperature and controls the output of your system to maintain the desired levels, so any issue affecting your thermostat will have a direct impact on your comfort. Therefore it’s very important to keep in mind the most common issues affecting this essential part of your AC system.
The AC Thermostat Is Exposed to Sunlight or Placed Near a Heat Source
If your thermostat is placed under direct sunlight, it will detect a warmer temperature. As a result, when you want to heat your home the system will turn off prematurely and when you want to cool it, it will run longer than needed, reducing the efficiency of your unit and increasing your energy bill.
The same principle applies when the thermostat is placed near a heat source. So, make sure to avoid the kitchen and plumbing and supply ducts when deciding where to place your thermostat.
The AC Thermostat is Old
Thermostats can be durable, but as any other part of your AC system, they must be replaced at some point. Old thermostats work with basic mechanical principles and may become inaccurate over time, with a negative impact on your comfort and your unit’s performance. If your thermostat is old, replacing it with a new, programmable one can take care of must thermostat issues you may be experiencing.
Dead Batteries
Some thermostats work with batteries, so it’s important to replace them periodically to ensure optimal performance. The most obvious sign that your thermostat needs new batteries is a blank screen. However, try to act preemptively and don’t wait until the batteries are dead to change them. Your thermostat display should include an indicator that shows the battery charge level. Use it as a reference to determine when to change the batteries.
The AC Thermostat is Dirty or Broken
Dirt accumulates on thermostats affecting the accuracy of the readings. This issue affects particularly old, mechanical thermostats. A technician can solve this problem by carefully removing the plastic cover and using a soft brush to clean the inside.
On the other hand, If your thermostat is broken, then it’s time to call the experts and get a replacement.
