FAQs
Why should I consider upgrading my current thermostat?
Older mechanical or basic digital thermostats can only turn your HVAC system on and off at a set temperature. Modern programmable and smart thermostats give you precise scheduling, remote control from your phone, and learning algorithms that automatically adjust settings for comfort and efficiency. All of this can lower heating and cooling costs by 8-20 %, reduce wear on your equipment, and provide better temperature consistency throughout your Allardt home.
What types of thermostat upgrades do your licensed technicians install?
We carry and install a full line of programmable, Wi-Fi, and smart thermostats from trusted brands such as ecobee, Honeywell, and Google Nest. Options range from simple 7-day programmable units to voice-controlled models that integrate with Amazon Alexa, Google Home, or Apple HomeKit. During our on-site visit we evaluate your HVAC system (gas furnace, heat pump, dual-fuel, or mini-split) and recommend the model that delivers the best combination of features, energy savings, and budget.
How long does professional thermostat installation take, and what’s included?
A standard replacement typically takes 45–90 minutes. Our licensed technician will: 1) shut down power to the furnace/air handler, 2) verify and label existing low-voltage wires, 3) mount the new thermostat base and level it, 4) connect the wiring to the correct terminals (including a C-wire adapter if needed), 5) power up and program the device, and 6) walk you through basic operation and app setup. We also dispose of your old thermostat in an environmentally responsible manner.
Will a smart thermostat work with my existing HVAC equipment?
In most cases, yes. Nearly all modern forced-air furnaces, air conditioners, and heat pumps installed in Allardt over the past 20 years use the industry-standard 24-volt (low-voltage) control wiring that smart thermostats require. If your system lacks a dedicated C-wire for continuous power, we can usually add one or install a compatible power extender kit. For specialty systems—such as geothermal, multi-stage, or ductless mini-splits—our technicians check manufacturer specifications to ensure full compatibility before installation.
Will upgrading my thermostat actually save me money on utility bills?
The U.S. Department of Energy estimates homeowners can save up to 10 % per year on heating and cooling by simply turning thermostats back 7–10 °F for 8 hours a day. A programmable or smart thermostat automates this process, so you never forget. Customers in Fentress County who switch from a non-programmable model typically report seeing their electric or gas bills drop within the first one to two billing cycles. Over the life of the thermostat (10–15 years), the energy savings usually exceed the cost of the device and installation several times over.
Are there any rebates or incentives for thermostat upgrades in Allardt or Tennessee?
Yes. Many local utilities, including Plateau Electric Cooperative, periodically offer bill credits or rebates—often $50–$100—for installing ENERGY STAR® certified smart thermostats. In addition, Tennessee customers may qualify for federal tax credits under the Inflation Reduction Act when the thermostat is installed as part of a qualifying HVAC upgrade. Our office keeps track of current programs and will supply the necessary documentation to help you claim any available incentives.
