What We Install and Support

• Smart and Wi‑Fi thermostats with app control, voice assistants, and geo‑fencing
• Programmable and non‑programmable digital thermostats for straightforward schedules
• Heat pump, dual‑fuel, and multi‑stage compatible thermostats
• Zoned system controls and remote room sensors for balanced comfort
• Humidity and IAQ integrations to support cleaner, healthier indoor air
• Upgrades from mercury/mechanical models to modern, code‑compliant devices

We work with most major thermostat brands and ensure compatibility with your furnace, air conditioner, or heat pump before any wiring changes are made.

Our 5‑Step Installation Process

• Assessment and compatibility check: We evaluate your HVAC equipment, staging, heat pump configuration, and confirm C‑wire power or provide safe alternatives.
• Clean removal and prep: We protect walls, label conductors, and verify low‑voltage integrity and polarity before installation.
• Precision mounting and wiring: We mount the base level, manage wiring per OEM specifications, and secure connections for long‑term reliability.
• System testing and calibration: We test heating/cooling changeover, staging, fan controls, heat pump modes, and calibrate temperature offsets and sensors.
• Setup, app pairing, and training: We connect Wi‑Fi, customize schedules, enable energy‑saving features, and show you exactly how to use it.

The result: a thermostat that communicates correctly with your HVAC system, delivers even temps, and helps lower energy use without sacrificing comfort.

Pricing Clarity, Warranties, and Safety

Expect upfront pricing with no surprises. Our workmanship is backed by a written labor warranty, and we follow manufacturer best practices to help protect equipment warranties. We follow local codes for Santa Monica and Los Angeles County, use proper low‑voltage techniques, and pull permits when required.

Energy Savings Without the Guesswork

Frequently Asked Questions

• Do I need a C‑wire? Many smart thermostats require constant power. If your system lacks a C‑wire, we can add one or use an approved solution that maintains equipment safety and performance.
• Will this work with my heat pump or multi‑stage system? Yes—our engineers verify staging, reversing valve logic (O/B), and auxiliary heat to ensure correct operation.
• How long does installation take? Most installs take about 60–120 minutes, including testing and walkthrough. Complex zoning or wiring corrections may take longer.
• Can you replace my old mercury thermostat? Absolutely. We remove and dispose of it responsibly, then install a modern, code‑compliant model with accurate control.
• Do you set up the app and teach me? Yes. We connect Wi‑Fi, pair the app, customize schedules, and give you a clear, step‑by‑step lesson.
