FAQs
Why should I consider upgrading my thermostat instead of keeping my current model?
Modern programmable and smart thermostats give you finer temperature control, automatic scheduling, and remote access through a phone or tablet. In Sweetwater’s hot summers and cool winters, that translates to fewer temperature swings, lower energy bills, and longer HVAC equipment life because the system doesn’t cycle as often. Many smart units also provide energy-use reports and maintenance alerts, helping you spot problems before they become costly repairs.
What kinds of thermostats do Certified HVAC Pros install in the Sweetwater area?
We carry and install three main categories: (1) Digital non-programmable thermostats—basic push-button control and an easy-to-read display; (2) Programmable thermostats—allow you to set different temperatures for weekday/weekend or up to seven individual days; and (3) Wi-Fi/Smart thermostats—feature app control, voice-assistant integration, geofencing, learning algorithms, and utility-provider demand-response capability. During a free on-site assessment we match the thermostat type to your HVAC system (single-stage, multi-stage, or heat pump) and to your lifestyle and budget.
How much can I expect to save on energy costs with a programmable or smart thermostat?
Savings vary by household, but nationally the EPA’s ENERGY STAR program reports average reductions of about 8% on heating and cooling when people actively program their thermostats. Wi-Fi smart models that use learning schedules and occupancy sensors often deliver 10–12% savings on heating and up to 15% on cooling. In Sweetwater, where cooling loads dominate, that can mean $120–$200 in annual utility savings for a typical 1,800-sq-ft home.
Will a new thermostat work with my existing HVAC equipment, or will I need additional upgrades?
In most cases your current heating and air conditioning system—whether it’s a gas furnace, electric air handler, or heat pump—will accept a new thermostat without changes. During our inspection we check voltage (24 V vs. line-voltage), staging (single, dual, variable), and whether a common (C) wire is present. If a C-wire is missing, we can often add a wire, install a power-extender kit, or recommend a battery-powered model that avoids rewiring. We make sure every installation preserves manufacturer warranties.
How long does a thermostat upgrade take, and will it disrupt my day?
A standard replacement typically takes 60–90 minutes: 15 minutes to shut off power and remove the old unit, 30–40 minutes for wiring and mounting the new thermostat, and 15–30 minutes to program schedules, connect to Wi-Fi, and verify system operation. We always protect floors and walls, and power to the HVAC equipment is off only during the swap, so your home comfort is interrupted for a very short time.
Are there any rebates or incentives for installing a smart thermostat in Sweetwater?
Yes. Oncor’s Home Energy Efficiency Program frequently offers $50–$100 bill credits or instant rebates on qualifying ENERGY STAR smart thermostats. Many utility companies in Texas also run demand-response programs that provide up-front incentives or annual bill credits when you allow slight temperature adjustments during peak demand. In addition, the federal Inflation Reduction Act (2022) offers a 30% tax credit, up to $600, for smart thermostat installations that meet ENERGY STAR criteria when combined with a qualifying HVAC upgrade. We help you identify and file for every incentive available.
