FAQs
Why should I upgrade my current thermostat?
Modern thermostats—especially smart and programmable models—offer tighter temperature control, automatic scheduling, remote access from your phone, and energy-use reporting. In Gruetli-Laager’s variable mountain climate, these features help reduce temperature swings, lower utility bills, and extend HVAC equipment life by preventing short-cycling and over-heating/cooling.
What types of thermostats do you install?
We install basic digital, 5-2/7-day programmable, Wi-Fi enabled, and fully smart learning thermostats from leading brands such as Ecobee, Honeywell, Nest, and Emerson. During our on-site visit we recommend the best model for your specific furnace, heat pump, or dual-fuel system and your home’s Wi-Fi strength.
How long does the upgrade take and will my HVAC be down?
Most thermostat replacements in Gruetli-Laager take 45-90 minutes, including wiring checks, mounting, and system calibration. Your HVAC system is powered down only during the wiring phase—usually 10–15 minutes—so comfort disruption is minimal.
Will a new thermostat be compatible with my existing heating and cooling equipment?
Yes. Before installation we verify control voltage (24 V, millivolt, or line-voltage), check the number of stage terminals (Y1, Y2, W1, W2, O/B, AUX, etc.), and confirm common-wire availability. If your older system lacks a C-wire, we can add an adapter or run a new conductor so the smart thermostat works reliably.
Can a smart thermostat really lower my energy bills in the Sequatchie Valley climate?
Studies by the EPA’s ENERGY STAR program show average savings of 8–15 % when switching from a non-programmable thermostat. In Gruetli-Laager, where humidity and temperature fluctuate sharply, features like geofencing, weather-adaptive algorithms, and humidity optimization often push savings closer to the upper end of that range.
What does the service cost and what warranties are included?
Typical installation ranges from $225 for a basic programmable unit to $475 for a premium smart thermostat, including the device, professional installation, and system calibration. Labor is warrantied for 12 months, and most thermostats carry a 3- to 5-year manufacturer’s warranty. We also offer extended maintenance plans that cover future firmware updates and seasonal HVAC inspections.
