Roger the Plumber, a local air conditioning, plumbing, and heating company, is urging homeowners to check thermostat batteries as most HVAC units are running nearly nonstop during summer months. Properly functioning thermostat batteries are key to maintaining cool indoor temperatures and controlling the HVAC unit.
A flashing or displayed battery symbol, flashing light, or any other type of uncommon alerts displayed by the thermostat may be signs that batteries are running low. Once the thermostat display has gone blank, batteries have most likely died out and the thermostat can no longer control the HVAC system. This could result in uncomfortable temperatures in the home.
Roger the Plumber General Manager Ian Williams says, “Procedures to replace thermostat batteries vary by model and manufacturer and homeowners should consult the owner’s manual for detailed instructions. Some models require AA or AAA alkaline batteries, while others may require lithium batteries. Rechargeable batteries are not recommended as they don’t provide proper voltage. We recommend homeowners reach out to the 4 Eco Services team with questions about checking and replacing thermostat batteries.”
