Comfort Sync® A3 Thermostat

Pro Series™ Systems

A system that’s built to deliver everything you want, just how you want it

Imagine what it would feel like to step through your front door and have your home feel just the way you want it to, every single day. That’s the power of the Pro Series, which is offered exclusively by the most experienced, professional AirEase dealers.

App Controlled

Every Pro Series system is created around the Comfort Sync® A3 thermostat, which allows you to control your home’s temperature from your smartphone or other mobile devices. Comfort Sync zoning allows even more personalization by dividing your home into up to four different areas, or zones, each with its own temperature control.

Voice Activated

Compatible with Amazon Alexa* and Google Assistant†, the thermostat enables you to fine-tune your comfort with a simple voice command.

Allergy Sync™

Monitors the air quality and pollen levels in your local ZIP/postal code and automatically turns the fan on to clean your home’s air when outdoor levels are high.

Away Sync™

Uses the GPS in your smartphone to detect when you are leaving and automatically changes the temperature to be more energy efficient. It also detects when you are returning and resets the temperature to its normal set point.

Schedule Sync™

Allows you to only program your thermostat once. Whenever there’s a change in your routine, the thermostat adapts heating and cooling to match.

A system built around you.

The Pro Series is about putting you in control. It’s about creating your environment, your way, every day. To make sure you get the exact system you need, the Pro Series includes a variety of equipment options that will let your Armstrong Air dealer design and build the ideal solution for your home.
