Why Upgrade Your Thermostat
Many Tucson homes still use basic mechanical thermostats with simple on/off controls. These older units waste energy by maintaining constant temperatures even when you’re away or asleep, lack the precision of digital controls, and can’t adapt to Tucson’s dramatic temperature swings between day and night.
Modern thermostats offer capabilities that directly address Tucson’s climate challenges. They learn your schedule and adjust automatically, allow remote control from your phone when plans change, provide detailed energy usage reports, and integrate with your HVAC system for maximum efficiency.
Smart thermostats can save homeowners 10-12 percent on heating bills and 15 percent on cooling bills on average. In Tucson where AC runs from April through October, these savings add up quickly, often $200-400 annually depending on your home size and usage patterns.
Types of Thermostats We Install
Smart Thermostats
Smart thermostats connect to your home Wi-Fi, allowing control from smartphones, tablets, or computers. They learn your preferences over time and adjust temperatures automatically based on occupancy, weather conditions, and your patterns.
Popular brands include Nest Learning Thermostat (learns your schedule automatically, away mode detects when you leave), Ecobee SmartThermostat (includes room sensors for multi-zone temperature monitoring), Honeywell Home T9 (focuses on rooms you’re using rather than hallway location), and Carrier Cor (designed for Carrier equipment with advanced integration).
Smart thermostats work particularly well for Tucson’s climate because they can pre-cool your home during off-peak hours when electricity rates are lower, adjust automatically when outdoor temperatures drop during evening hours, and send alerts if your system isn’t cooling properly during extreme heat.
Many integrate with voice assistants like Alexa or Google Home, letting you adjust temperatures hands-free. This convenience matters when you’re working from home and need to cool your office quickly without leaving your desk.
Programmable Thermostats
Programmable thermostats allow you to create daily or weekly schedules without requiring Wi-Fi connectivity. You set specific temperatures for different times, and the thermostat follows that schedule automatically.
These work well if you maintain consistent routines, leaving for work at the same time daily, returning home at predictable hours. You program comfortable temperatures when you’re home and energy-saving settings when you’re away.
Most programmable models offer 7-day programming (different schedule each day), 5-2 programming (weekdays vs. weekends), or 5-1-1 programming (weekdays, Saturday, Sunday). For Tucson homeowners with varying schedules, 7-day programming provides maximum flexibility.
Programmable thermostats cost less than smart models ($80-150 vs. $150-300) while still delivering significant energy savings. They’re a practical choice if you don’t need remote access or smart features.
Digital Non-Programmable Thermostats
Digital thermostats provide accurate temperature control and easy-to-read displays without programming capabilities. They’re simple to operate, just set your desired temperature and the system maintains it.
These suit situations where simple control is preferred, like rental properties, guest houses, or for homeowners who prefer manual temperature adjustments. They cost $40-80 installed and provide more accurate temperature control than old mechanical thermostats.
Our Installation Process
1. Compatibility Check
Not all thermostats work with every HVAC system. During your consultation, we verify compatibility by examining your current thermostat wiring, identifying your HVAC system type (heat pump, gas furnace, AC only, etc.), checking if you have a C-wire for power (required by most smart thermostats), and confirming your Wi-Fi signal strength reaches the thermostat location for smart models.
If your system lacks a C-wire, we can often add one or use wireless power adapters that some thermostat manufacturers provide.
2. Thermostat Selection
Based on your system, budget, and preferences, we recommend specific models. We explain the differences between options, focusing on features that actually benefit Tucson homeowners rather than gimmicks you won’t use.
We consider factors like how much you travel (geofencing becomes more valuable), whether you have consistent schedules (programming is sufficient) or variable routines (smart learning helps), if you want detailed energy tracking, and whether voice control integration matters to you.
3. Professional Installation
Thermostat installation typically takes 30-60 minutes for straightforward replacements. We shut off power at the breaker for safety, remove your old thermostat and document existing wiring, mount the new thermostat base level on the wall, connect wires according to your HVAC system requirements, restore power and test all functions, and program basic settings and connect to Wi-Fi for smart models.
For installations requiring a new C-wire, we run the wire from your air handler to the thermostat location. This additional work extends installation time to 1-2 hours but ensures reliable operation.
4. Programming and Setup
After installation, we program your thermostat based on your schedule and preferences. For smart thermostats, this includes connecting to your Wi-Fi network, linking to your smartphone app, setting up geofencing if desired, creating initial schedules, and configuring alerts and notifications.
We ensure you understand how to use all features before leaving. You’ll be comfortable adjusting settings, creating schedules, and using the smartphone app if applicable.
Optimizing Settings for Tucson Climate
Proper thermostat settings balance comfort and efficiency. For Tucson’s climate, we recommend these guidelines:
Summer cooling: Set to 78°F when home, 82-85°F when away during the day. Each degree below 78°F increases cooling costs by approximately 3-5%. While 78°F might seem warm initially, ceiling fans and proper humidity control make it comfortable.
Evening adjustments: Take advantage of cooler evenings. If outdoor temperature drops below 80°F after sunset, you might reduce AC usage or rely on evaporative cooling. Smart thermostats handle this automatically.
Pre-cooling strategies: On time-of-use rate plans, pre-cool your home to 76°F during off-peak hours (before 3 PM), then let temperature drift to 80°F during expensive peak periods (3-8 PM). Your home’s thermal mass maintains comfort while reducing costs during expensive hours.
Winter heating: Set to 68-70°F when home, 62-65°F overnight or when away. Tucson’s mild winters mean heating runs intermittently, making the savings from nighttime setbacks less dramatic than in colder climates.
Fan settings: Use “auto” rather than “on” for most situations. Running the fan continuously wastes energy and doesn’t improve comfort significantly in Tucson’s dry climate. However, during monsoon humidity, running the fan on “auto” helps remove moisture.
TEP Rebate for Smart Thermostats

Common Thermostat Installation Issues We Solve
Missing C-Wire
Many older Tucson homes lack a common wire (C-wire) that provides continuous power to smart thermostats. Without it, batteries drain quickly or the thermostat won’t function reliably.
We solve this by running a new C-wire from your air handler, using a power adapter provided by some manufacturers, or upgrading your thermostat wiring entirely if needed.
Incompatible Wiring
Some HVAC systems use non-standard wiring that doesn’t match typical thermostat configurations. Heat pumps with auxiliary heat, dual-fuel systems, or older equipment may require special consideration.
Our technicians have experience with all system types and ensure proper wiring that maintains all your HVAC functions.
Wi-Fi Connectivity Problems
Smart thermostats require reliable Wi-Fi at their installation location, often hallways or entryways where signal strength can be weak. We verify connectivity before installation and recommend solutions if signal strength is inadequate.
Incorrect HVAC System Configuration
Smart thermostats need to know your specific HVAC system type to operate correctly. Configuring the wrong system type can cause short-cycling, inefficient operation, or equipment damage.
We properly configure thermostats based on your actual equipment, ensuring compatibility with heat pumps, multi-stage systems, or other specialized equipment.

Beyond Basic Thermostat Installation
Whole-Home Integration
Smart thermostats integrate with other smart home devices. You can create automation routines like “leaving home” that adjusts your thermostat, turns off lights, and arms your security system simultaneously.
Voice control through Alexa or Google Assistant lets you adjust temperatures hands-free. This convenience matters when cooking, working, or your hands are full.
Multiple Thermostats for Zoning
Homes with multiple HVAC systems benefit from installing smart thermostats on each system. The thermostats coordinate through your smartphone app, giving you complete control over different zones from a single interface.
For example, you might cool your main living area during the day while keeping bedroom zones at energy-saving temperatures, then reverse this pattern in the evening.
When to Upgrade Your Thermostat
Your current thermostat is mechanical or old digital: If you’re using a round dial thermostat or an early digital model from the 1990s-2000s, upgrading delivers immediate benefits in accuracy and efficiency.
You’re installing new HVAC equipment: When installing a new AC or heat pump, upgrade your thermostat simultaneously. New equipment often includes enhanced features that older thermostats can’t utilize.
Your energy bills are higher than expected: If cooling costs seem excessive, an upgraded thermostat with better scheduling and features can reduce consumption significantly.
Your schedule varies or you travel frequently: Smart thermostats with geofencing and remote control adapt to changing schedules better than basic programmable models.
You want better comfort control: If some rooms feel uncomfortable while others are fine, thermostats with room sensors provide better whole-home comfort.
