Residential Thermostat Installation in Rialto, CA

Engineered Comfort, Installed Right the First Time

Your thermostat is the brain of your home’s comfort system. When it’s installed and configured by engineers, your HVAC runs smoother, lasts longer, and delivers cleaner, healthier air. At #1 AC Guys, our fourth‑generation family of engineers brings 80+ years of engineering expertise to Rialto homes—pairing real craftsmanship with modern smart controls.

Our mission is healthy air at home for healthy living. Accurate temperature, proper ventilation, and balanced humidity begin with a properly selected and calibrated thermostat. We make sure your control matches your equipment and your lifestyle, from simple programmable models to advanced smart thermostats that optimize comfort and efficiency.

What We Install

• Smart Wi‑Fi and app‑enabled thermostats
• Programmable and non‑programmable digital thermostats
• Heat pump and dual‑fuel compatible controls
• Multi‑stage and communicating system thermostats
• Zoning thermostats and panels for multi‑zone homes
• Humidity and ventilation‑integrated controls

Before installation, we complete a compatibility audit and wiring map to protect your equipment and ensure full feature support.

What’s Included in a Professional Installation

• Site evaluation, compatibility check, and safety power‑off
• Clean removal of the old thermostat and wall surface prep
• Level mounting with anchors; seal wall cavity to block drafts
• Correct wiring termination, labeling, and C‑wire solutions
• Heat pump settings, outdoor sensor mapping, and staging
• Firmware updates, schedule programming, geofencing setup (as applicable)
• Full system test: heat, cool, fan, defrost, and emergency modes
• User training so your new control is intuitive from day one

Every step is documented and verified. If we find risks—like back‑fed power, incorrect jumper settings, or undersized wiring—we fix them before commissioning.

5) Walkthrough and support: We show you how to use your thermostat, then stand behind the work.
