Thermostats & Zoning

Heil Observer Thermostat

Maximum Comfort Control

Wi-Fi enabled thermostats and zoning systems offer the highest degree of options to allow you to control the temperature, humidity, airflow, and air quality of your home from any device that is connected to the internet.

Wi-Fi enabled thermostats can also offer quality of life features like touch screens, filter replacement reminders, energy usage reports, weather forecasting, and even system diagnostics.

Zoning systems allow you to control the temperature and humidity in specific areas or zones in your home. If you’ve ever thought to yourself that it was too hot upstairs while it was freezing downstairs, a zoning system could be perfect for your home!
