FAQs
How can a programmable smart thermostat lower my energy bills in Greenback’s climate?
Greenback experiences warm, humid summers and fairly mild winters, which means your HVAC system runs much of the year. A smart thermostat learns your comfort preferences and automatically adjusts temperatures when you are asleep or away, reducing unnecessary heating and cooling. It also tracks local weather data to fine-tune run times, so the system doesn’t work harder than needed. According to the U.S. DOE, homeowners save 8-15 % on utility costs after upgrading to a smart, properly programmed thermostat—often more in a mixed climate like ours where both AC and heat are used.
Are your smart thermostats compatible with my existing heating and air-conditioning equipment?
Most likely, yes. Our models support single-stage and multi-stage gas furnaces, heat pumps, electric strip heat, dual-fuel, and conventional AC systems commonly installed in Greenback. During our free home survey, a technician checks the control board, wiring (including the presence of a C-wire), and voltage to confirm compatibility. If an additional common wire or adapter is needed, we install it at the same visit.
Can I control the thermostat remotely and create custom schedules?
Absolutely. Once the thermostat is connected to your home Wi-Fi, you can use our iOS and Android app or any web browser to change temperature settings, create 7-day schedules, set vacation modes, and receive energy-use reports from anywhere. The device also integrates with Alexa, Google Assistant, and Apple HomeKit so you can make hands-free adjustments with voice commands.
What is the installation process and do I need a professional?
Most homeowners prefer professional installation to ensure wiring is correct and the thermostat is configured for their exact HVAC equipment. We schedule a 60-minute visit, remove the old thermostat, label and transfer wires, mount the new unit, connect it to Wi-Fi, perform a system test, and walk you through the app. DIY installation is possible if you’re comfortable turning off breaker power, matching wires to labeled terminals, and following on-screen prompts—just keep in mind that improper wiring can void HVAC warranties.
Will the thermostat still work during an internet or power outage?
If your Wi-Fi goes down, the thermostat continues to follow the most recently saved schedule and you can adjust settings manually at the wall unit. Cloud-based features such as remote control and weather-responsive routines pause until the connection is restored. During a power outage, the thermostat’s internal battery preserves the clock and settings for several hours, but the HVAC equipment itself will not operate until mains power returns.
Are there rebates or incentives for smart thermostats in Greenback?
Yes. Knoxville Utilities Board (KUB) and some surrounding co-ops offer bill credits—typically $30–$50—when you install an ENERGY STAR® certified smart thermostat. Tennessee Valley Authority (TVA) programs occasionally add seasonal incentives. We handle all paperwork, including proof of purchase and serial numbers, so you receive the rebate or credit automatically after installation.
