4 Reasons Your Thermostat in Mount Juliet, TN, Has Called It Quits

February 18, 2021

Winters can get chilly in Mount Juliet, TN. A failed thermostat could cause your furnace to quit working properly, causing a number of issues impacting the comfort of your home and costing you money. Read on to learn about four reasons why your thermostat might fail.

No Power

Thermostats require power to engage the HVAC system to heat and cool your home. Dead batteries are an easy fix, but wiring and other issues can also cause a tripped breaker or a blown fuse. A professional HVAC technician can check out these and other issues during a service call.

A Dirty Thermostat

Dust, cobwebs and pet hair can collect inside your thermostat, leading to internal connectivity issues. If you delay cleaning long enough, the terminals inside may corrode.

Mechanical Thermostat Issues

If you have a mechanical thermostat, the internal parts may fail, causing heating and cooling issues. Additionally, these thermostats need to sit level to work properly. A bump from a passerby may knock them off level, causing improper operation.

Mechanical thermostats have other limitations, too. If your home still has an older type, you can’t take advantage of programming your HVAC system to heat and cool your home when appropriate. If you upgrade to a programmable thermostat, you can turn back the furnace at night when the family is asleep and during the day when everyone is at work or school.

It’s Just Time

Thermostats aren’t meant to last forever. Eventually, they will need replacement. An HVAC technician can help you choose the right upgrade for your system and your budget. If you’re concerned about the performance of your thermostat, call the professionals at Derryberry’s Heat & Air for inspections and repairs. Our team will answer any questions you have about our services and your heating and cooling system.
