Thermostat replacement. Whether you want the many advantages of today’s smart thermostats or just want a more modern-looking appearance for your home, we can help you choose the right model.

Thermostat installation. Thermostats generally use thin wires for their connections, and it’s all too easy to have one come lose or get tangled. Our team does the job correctly and tests it to make sure.

Is Your Home’s Thermostat Ready For Replacement?

The thermostat in your Charlotte-area home may be small, but it plays a very big role in ensuring you and your family stay comfortable all year ‘round. 24 hours a day, 365 days a year, your home’s thermostat manages the temperature of your home. During the winter, when it detects that your home is getting chilly, it kicks on the heat. In summer months, it senses when your home is becoming uncomfortable, so it starts the AC.

Because thermostats don’t draw attention to themselves, it might not be obvious that something is wrong with yours. Common signs of a potential thermostat problem include:

Higher bills. If you’ve noticed that your energy bills are climbing because you’re using more energy, your thermostat may no longer be operating efficiently. Those extra costs can add up quickly!

Short cycles. Your Charlotte home’s heating and cooling turn on as needed, usually run for several minutes, then stop running when the thermostat says the temperature is correct. If they kick on every couple minutes and run for a short time, something may be wrong with the thermostat.

Intermittent operation. Sometimes, a failing thermostat may work okay for part of the time, and then stop working altogether for a while.

Wrong temperature. If your thermostat says it’s 74° indoors, but another thermometer says your Charlotte-area home is much warmer than that, the thermostat may need repair or replacement.

Old age. Like all home devices, thermostats don’t last forever. If your thermostat is older than 10 years, it may not be performing as well as you need and should be replaced.

Limited options. Charlotte homes were often built with the most basic analog thermostats, which can’t offer the many features available with today’s digital and smart thermostat models.

If your home’s thermostat is giving you problems or you just want to upgrade to a newer model, contact our team for fast, affordable replacement today!
