Imagine arriving home from a long day only to find your home unusually hot or cold and your HVAC system’s thermostat blank. So you attempt to diagnose the problem - you move a few controls, double-check the circuit breakers and...nothing. When this happens, the problem isn’t with your HVAC system – it’s usually as simple as a dead battery.Dead thermostat batteries are actually a common enough problem that elicits service calls to an HVAC technician. However, you don’t need a technician to take care of this issue. Here’s what you need to know when your thermostat batteries need replacing:
Your thermostat will actually let you know days or even weeks in advance when your batteries need replacing, usually with a “dead battery” warning or symbol flashing on the thermostat display.
Before changing your batteries, find out what size cells your thermostat uses. Most thermostats use AA or AAA alkaline batteries, while others rely on CR2032 3-volt lithium batteries.
Read up on how to properly change the batteries without damaging the thermostat itself. Your operator’s manual should offer some instructional help, including a pictorial diagram of the thermostat and its battery location.
Be careful when removing and replacing batteries, not just to reduce shock but also to avoid handling battery acid.
Knowing when your thermostat batteries need replacing and how to change them will save you a diagnostic fee and the embarrassment of an unnecessary technician visit.Don’t hesitate to contact Air Assurance for expert advice on your home’s heating and cooling needs.
