Thermostat Installation and Repair

Why your thermostat matters

A correctly matched and calibrated thermostat improves comfort, reduces energy waste, and extends the life of your HVAC system. Poor wiring, incorrect settings, bad placement, or a failing sensor can cause short cycling, uneven temperatures, or constant system run time. Our trained technicians diagnose the root cause and resolve it properly the first time.

What we install and repair

We work with all major thermostat types:

• Manual and digital non-programmable thermostats
• 5-2 and 7-day programmable thermostats
• Smart Wi‑Fi thermostats with app control
• Wireless and battery-powered models
• Low-voltage and line-voltage thermostats where applicable

Common HVAC connections we handle include R, RC, RH, Y, W, G, C, O/B terminals. If your system lacks a C‑wire, we can often add one, fit a power extender kit, or recommend a compatible solution.

Signs you may need thermostat service

• Rooms feel too hot or too cold compared to the set point
• System turns on and off rapidly or runs non-stop
• Display is blank, flickering, or buttons are unresponsive
• Unexpected spikes in energy bills
• The fan runs but no cooling or heating starts
• Wi‑Fi thermostat keeps dropping connection or will not pair

If you notice any of the above, it is wise to book a quick inspection to prevent larger HVAC issues.

Our process

1) Diagnose

We start with a careful check of wiring, voltage, fuse and breaker status, sensor accuracy, and control signals. We also assess placement to avoid drafts, direct sunlight, or nearby heat sources that skew readings.

2) Recommend

You get clear options that fit your system and lifestyle. We explain the pros and cons of programmable versus smart models, compatibility, and expected savings.

3) Install or repair

We use proper wiring practices, secure connections, and manufacturer-approved mounting. For smart thermostats, we complete pairing, firmware updates, and app setup.

4) Test and calibrate

We run functional tests for cooling, heating, fan, and auxiliary stages. We calibrate temperature and fine-tune settings for comfort and efficiency.

5) Guide and support

We walk you through features, build schedules together, and share tips for best performance. After service, you can reach us if you have questions.

Smart thermostat advantages

• Remote control via phone and voice assistant
• Energy reports and usage insights
• Geofencing to auto-adjust when you leave or return
• Adaptive learning that fine-tunes schedules
• Alerts for maintenance or unusual temperature changes

A smart thermostat can help lower energy costs when paired with realistic schedules and occupied setpoints. We configure features to match your routine so you actually benefit from the tech.

Choosing the right thermostat

• System type: AC only, heat pump with or without auxiliary heat, furnace, or mixed systems
• Stages: Single-stage or multi-stage heating and cooling
• Power: Availability of a C‑wire or need for an adapter
• Features: Scheduling, remote access, learning, sensor add-ons, lockouts for commercial spaces
• Display and controls: Touchscreen visibility, child lock, and accessibility preferences

Not sure what fits your setup? We evaluate your air handler, condenser or heat pump, and existing controls before recommending the ideal model.

• Skilled technicians with hands-on HVAC experience
• Genuine parts and code-compliant workmanship
• Careful protection of your walls and finishes
• Transparent, upfront pricing
• Warranty on labor and manufacturer-backed parts
