FAQs
Why should I consider upgrading my thermostat in Sewanee?
Older mercury or slider-style thermostats can be off by several degrees, forcing your HVAC equipment to run longer than necessary. A modern programmable or smart thermostat provides precise temperature control, learns your schedule, and can be managed from your smartphone. In Sewanee’s four-season climate—where mornings may be chilly even in spring—these features translate into 5–15% lower annual energy costs, greater comfort, and less wear on expensive heating and cooling components.
Which thermostat brands do your certified technicians install and service?
Our NATE-certified technicians are factory-trained to install and support leading products such as ecobee, Nest, Honeywell Home (T-series and VisionPRO), Emerson Sensi, and Carrier Infinity thermostats. We stock models specifically rated for heat-pump applications that are common in Sewanee and the surrounding Cumberland Plateau area, ensuring full compatibility with dual-fuel and variable-speed systems.
Will a smart thermostat work with my existing HVAC system?
In most cases, yes. During a free onsite assessment, we verify low-voltage (24 V) wiring, confirm the presence of a "C" (common) wire, and test your furnace or heat pump’s control board. For older systems lacking a C-wire, we can often add a Power Extender Kit or run new wiring without major wall repairs. Our technicians also check for zoning panels, humidifiers, and dehumidifiers to make sure all accessories integrate seamlessly with the new thermostat.
How long does a professional thermostat upgrade take and what does it involve?
A straightforward swap takes about one hour. We begin by safely shutting down power, labeling existing wires, and removing the old control. After mounting the new backplate and leveling it for a clean look, we connect and verify each wire, power up the system, program your preferred schedules, and walk you through the mobile app setup. If additional wiring is needed, the visit may extend to 2–3 hours, but most homeowners in Sewanee have full control of their new thermostat the same day.
Are there rebates or incentives available for thermostat upgrades in Sewanee?
Yes. The Tennessee Valley Authority (TVA) EnergyRight program often offers $50–$100 bill credits for qualifying smart thermostats, and some electric co-ops on the Plateau run seasonal promotions as well. We handle all paperwork, provide proof of ENERGY STAR® certification, and submit your rebate application online, so you receive your incentive without hassle.
What warranty and support do you provide after installation?
Every thermostat we install comes with the manufacturer’s 3–5 year parts warranty, and our labor is guaranteed for one year. If your device malfunctions, simply call us—our technicians will return at no charge to diagnose and replace the thermostat if needed. We also offer low-cost remote monitoring plans that alert us to temperature spikes or connectivity issues, keeping your Sewanee home comfortable year-round.
