FAQs
Why should I upgrade my thermostat when installing a new heating and air conditioning system in Charleston?
A modern smart or programmable thermostat maximizes the efficiency of a new HVAC system by precisely regulating temperature based on your schedule and Charleston’s humid subtropical climate. Upgrading can cut energy use by 10–20 %, extend equipment life by reducing short-cycling, and give you convenient remote control via smartphone apps.
Are smart thermostats compatible with all types of HVAC systems you install?
Most smart thermostats are compatible with single-stage, multi-stage, and variable-speed heat pumps and gas furnaces. During our seamless installation process, our technicians verify the control board voltage (24 V vs. line-voltage), the number of required control wires, and any auxiliary heat strips common in Lowcountry homes. If your system is older or uses proprietary controls, we’ll recommend an adapter or an alternative model that ensures full functionality.
How long does a thermostat upgrade and HVAC installation typically take?
A standard full system replacement with thermostat upgrade is usually completed in one day. The timeline breaks down to 4–6 hours for removing the old equipment, placing the new indoor and outdoor units, pressure testing and charging the refrigerant lines, plus 30–60 minutes for mounting, wiring, and programming the new thermostat. Larger homes or ductwork modifications can extend the job to a second day, but you’ll have cooling or heating before we leave each evening.
Will a new thermostat help me qualify for energy rebates in Charleston or South Carolina?
Yes. Dominion Energy South Carolina and Santee Cooper frequently offer rebates of $50–$75 for ENERGY STAR-certified smart thermostats when installed by a licensed contractor. In many cases, pairing the thermostat with a high-efficiency heat pump raises your total incentive. We handle the paperwork, provide proof of installation, and submit serial numbers so you can receive your rebate check in 4–8 weeks.
Can I control my upgraded thermostat remotely and integrate it with voice assistants?
All of the smart thermostats we offer—Nest, ecobee, Honeywell Home, and Trane ComfortLink II—include Wi-Fi capability. Once connected to your home network, you can adjust temperature, humidity setpoints, and schedules from iOS or Android apps, a web dashboard, or voice commands using Amazon Alexa, Google Assistant, or Apple HomeKit. We walk you through account setup and pair your devices before we finish the installation.
What if I have uneven temperatures in different rooms after the upgrade?
Uneven temperatures can stem from ductwork issues rather than the thermostat itself. However, many smart thermostats support remote sensors that detect temperature and occupancy in individual rooms. We can place these sensors in problem areas, and the thermostat will automatically balance run times to improve comfort. If airflow problems persist, our technician will inspect dampers, insulation, and duct sizing during your installation visit and suggest targeted fixes.
