FAQs
Why should I upgrade my thermostat instead of keeping my current model?
Newer thermostats—especially programmable and smart models—offer tighter temperature control, energy-saving schedules, and remote access from your phone. In Charleston’s humid subtropical climate, precise control helps reduce excessive run-times that drive up utility bills and wear out HVAC equipment faster. Many customers report 10–20 % savings on annual heating and cooling costs after switching to an upgraded thermostat.
Which thermostat features are best suited for Charleston’s climate?
Look for models with humidity sensors, adaptive recovery, and geofencing. Humidity sensing lets the thermostat run your AC’s dehumidification cycle automatically, preventing that sticky indoor feel common in Charleston summers. Adaptive recovery learns how long your system needs to reach a setpoint, so your home is comfortable right when you wake up without running the unit longer than necessary. Geofencing uses your phone’s location to set the system back when you leave Folly Beach or commute downtown, then restores comfort as you head home.
Can my existing HVAC system handle a smart thermostat?
Most modern gas furnaces, heat pumps, and dual-fuel systems in the Lowcountry are compatible, but the key factor is having a C-wire (common wire) for continuous power. If your system lacks one, our technicians can usually add a C-wire at the air handler or install a power extender kit during the same visit. Before scheduling, we offer a free compatibility check to avoid surprises.
How long does professional installation take, and will my HVAC be offline?
A standard thermostat replacement takes about 60–90 minutes. We shut off power, remove the old unit, label and test existing wires, mount the new thermostat, program initial settings, and verify cooling and heating operation. Your HVAC will be off only during the wiring step—typically 15–20 minutes—so indoor comfort is minimally affected.
What is the average cost for a thermostat upgrade in Charleston?
Prices vary with feature sets: • Basic 7-day programmable units: $175–$250 installed. • Wi-Fi enabled, app-controlled models: $295–$425 installed. • Premium smart thermostats with learning algorithms and humidity control: $450–$650 installed. All prices include hardware, labor, and a 1-year workmanship warranty. Additional wiring or zoning interface modules can add $50–$150.
Will upgrading void my HVAC warranty or affect my energy rebates?
No—using a thermostat approved by your equipment manufacturer keeps your warranty intact, and many smart models are listed as qualified accessories by major brands. In fact, Dominion Energy South Carolina currently offers up to a $75 rebate for installing an ENERGY STAR® certified smart thermostat. We handle the paperwork and provide the documentation you need to claim the rebate.
