FAQs
Why should I consider upgrading my thermostat in Winfield?
Older manual or programmable thermostats can be inaccurate, hard to use, and limited in features. A modern smart thermostat learns your schedule, provides remote control via phone, automates temperature setbacks, and generates energy-use reports. Customers in Winfield typically see 8–15 % savings on annual heating and cooling costs, more consistent comfort, and the convenience of voice or app control.
What kinds of thermostats do you install?
We install a full range of Wi-Fi and smart thermostats, including Nest, ecobee, Honeywell T Series, and Emerson Sensi. We also offer advanced communicating thermostats that pair with high-efficiency furnaces and air conditioners. During our free on-site assessment we match you with models that fit your HVAC equipment, budget, and desired features—whether that’s geofencing, humidity control, energy-use dashboards, or multi-stage support.
How much does a thermostat upgrade cost in Winfield?
Pricing depends on the model and your existing wiring. Basic Wi-Fi units start around $249 installed, mid-range smart models average $375–$450, and premium communicating thermostats range from $550–$750. Your quote includes the thermostat, professional installation, system calibration, Wi-Fi setup, and a one-year labor warranty. We’ll also tell you about utility rebates (currently up to $100 from Ameren Illinois) that can lower your out-of-pocket cost.
Will a new thermostat work with my current heating and air-conditioning system?
In most cases, yes. Our licensed technicians verify compatibility with single-stage, multi-stage, heat pump, dual-fuel, and even boiler systems. If your existing wiring lacks a C-wire (common wire) we can usually add one or install a power extender module. For older or proprietary systems we’ll recommend a compatible model or discuss other upgrade options before any work is done.
What is the installation process and how long will it take?
On the scheduled day we arrive within a one-hour window, shut off power to your HVAC equipment, remove the old thermostat, label and test wiring, and mount the new unit. We then power up the system, walk through on-screen configuration, connect the thermostat to your Wi-Fi, and show you how to use the mobile app. Most installations take 45–90 minutes, with minimal disruption to your home.
Do smart thermostats really save energy, and how can I track those savings?
Yes. Smart thermostats use occupancy sensors, learning algorithms, and local weather data to optimize run times automatically. Studies by the EPA’s ENERGY STAR program show average savings of 8 % on cooling and 10 % on heating. The thermostats’ dashboards display daily runtime, temperature history, and estimated dollars saved, so you can see the impact in real time and on your monthly utility bill.
