Your thermostat is the control center of your entire HVAC system. It determines when your air conditioner runs, when your furnace ignites, and how much energy your home consumes every month. In Las Vegas — where cooling accounts for 40-60% of summer energy bills — the right thermostat with a proper installation can reduce monthly costs by $15 to $50 or more.
But installation is not as simple as removing the old unit and snapping a new one in place. Las Vegas homes have diverse HVAC configurations — single-stage, two-stage, variable-speed, heat pump, dual fuel, and multi-zone systems — and each requires specific wiring and thermostat compatibility. An improperly installed thermostat can cause short cycling, uneven temperatures, system lockouts, and even premature equipment damage.
The Cooling Company handles thermostat installation correctly from the start. Our licensed technicians verify compatibility with your existing system, handle all wiring (including running a common wire if needed), configure the thermostat for your specific equipment, and test every operating mode before leaving.
Thermostat Types We Install
Smart Thermostats
Smart thermostats connect to your home's Wi-Fi and offer remote control through smartphone apps, learning algorithms that adapt to your schedule, energy usage reports, and integration with voice assistants like Alexa and Google Assistant. They represent the most advanced option and deliver the greatest energy savings for most Las Vegas homeowners.
Popular smart thermostat models we install:
- Google Nest Learning Thermostat — learns your schedule and preferences automatically, adjusts when you leave, and provides monthly energy reports. The latest model includes a temperature sensor for remote rooms.
- Ecobee Smart Thermostat Premium — includes a built-in air quality monitor, room sensor for temperature balancing, Alexa voice control, and SmartSensor technology that prioritizes occupied rooms.
- Honeywell Home T9/T10 Pro — robust smart features with multi-room sensor support, geofencing, and compatibility with virtually every HVAC system type including complex multi-stage and dual-fuel setups.
- Lennox S40 — designed specifically for Lennox iComfort systems, providing the deepest integration with Lennox equipment for maximum efficiency and diagnostics.
- Carrier Cor — ideal for homes with Carrier or Bryant equipment, offering native system integration and energy tracking.
Programmable Thermostats
Programmable thermostats allow you to set a daily and weekly schedule so your system automatically adjusts temperatures when you are away, asleep, or home. They do not require Wi-Fi or a smartphone and are an excellent upgrade from basic non-programmable models.
- 7-day programmable — different schedule every day of the week, ideal for varied routines
- 5-1-1 programmable — one schedule for weekdays, separate schedules for Saturday and Sunday
- 5-2 programmable — one weekday schedule, one weekend schedule
Basic/Standard Thermostats
Non-programmable thermostats provide simple temperature control with a manual set point. While they lack scheduling and remote features, they are reliable, affordable, and straightforward. We install these when homeowners prefer simplicity or when budget is the primary concern.

Why Proper Installation Matters
A thermostat is only as good as its installation. Here is why professional installation is worth the investment — especially in Las Vegas:
- System compatibility verification — not every thermostat works with every HVAC system. Two-stage systems, variable-speed blowers, heat pumps, and dual-fuel setups require specific thermostat capabilities and wiring. Our technician verifies compatibility before purchasing and installing.
- Proper wiring — most smart thermostats require a "C-wire" (common wire) for continuous 24V power. Many older Las Vegas homes have only 4-wire thermostat cables. We can run a new C-wire or install a power adapter to ensure reliable operation without battery drain or power-stealing issues.
- Correct configuration — your thermostat must be programmed to match your equipment type (conventional vs. heat pump), staging (single, two-stage, variable), fan control mode, and auxiliary/emergency heat settings. Incorrect configuration causes short cycling, temperature swings, and unnecessary wear.
- Optimal placement — if your existing thermostat is in a poor location (near a window, in direct sunlight, in a hallway with no return air), we can relocate it to a position that provides accurate temperature readings.
- Sensor setup — smart thermostats with remote sensors need proper placement and configuration to balance temperatures across rooms, a feature that is particularly valuable in two-story Las Vegas homes where the upstairs is significantly hotter than the main level.
How Smart Thermostats Save on Las Vegas Energy Bills
Las Vegas homeowners pay some of the highest cooling costs in the country. NV Energy rates combined with 4-5 months of intense cooling demand mean that even small efficiency improvements produce meaningful savings. For detailed data on real-world savings, read our deep dive on smart thermostat energy savings. Here is how smart thermostats reduce those costs:
- Automatic away detection — geofencing and occupancy sensing let the system set back temperatures when nobody is home, avoiding cooling an empty house to 72 degrees on a 115-degree day
- Optimized scheduling — learning algorithms adjust pre-cooling and recovery times based on outdoor temperature and your home's thermal characteristics, preventing unnecessary early starts
- Demand response programs — many smart thermostats participate in NV Energy's demand response program, earning rebates or credits for allowing minor temperature adjustments during peak grid demand
- Energy usage reports — monthly reports show exactly how many hours your system ran, helping you identify unusual patterns that indicate maintenance needs or setting changes
- Multi-room balancing — remote sensors focus cooling on occupied rooms rather than the hallway where the thermostat lives, reducing overall runtime while improving comfort where you actually spend time
The Department of Energy estimates that proper thermostat programming can save 10% per year on heating and cooling. In Las Vegas, where annual HVAC costs often exceed $2,500, that translates to $250 or more in annual savings — meaning most smart thermostats pay for themselves within 1 to 2 years.

Frequently Asked Questions
Can I install a smart thermostat myself?
Some homeowners successfully install smart thermostats themselves, but there are risks. If your system requires a C-wire and you do not have one, if you have a heat pump or multi-stage system, or if your wiring does not match the new thermostat's requirements, incorrect installation can damage your HVAC equipment or void warranties. Professional installation costs $125 to $225 and ensures everything is done correctly, including configuration for your specific system.
What is a C-wire and do I need one?
A C-wire (common wire) provides continuous 24V power from your HVAC system to your thermostat. Most smart thermostats need a C-wire to power their Wi-Fi radios, displays, and sensors without draining batteries or stealing power from the control circuit. Many older Las Vegas homes have only 4-wire thermostat cables and lack a C-wire. We can run a new C-wire or install a compatible power adapter during your thermostat installation.
Which smart thermostat is best for Las Vegas?
The best thermostat depends on your HVAC system and priorities. The Google Nest Learning Thermostat is excellent for most homes with its intuitive learning algorithm. The Ecobee Premium is ideal if you want built-in air quality monitoring and Alexa. The Honeywell T9 is the most compatible option for complex systems (multi-stage, dual-fuel). If you have Lennox equipment, the Lennox S40 offers the deepest system integration. We evaluate your specific setup and recommend the best match.
How much can a smart thermostat save on energy bills in Las Vegas?
The Department of Energy estimates properly programmed thermostats save about 10% on annual heating and cooling costs. In Las Vegas, where typical annual HVAC costs range from $2,000 to $3,500, that translates to $200 to $350 in savings per year. Homeowners who previously used a non-programmable thermostat often see even larger savings. Most smart thermostats pay for themselves within 1 to 2 years.
Will a new thermostat work with my older HVAC system?
In most cases, yes. Smart and programmable thermostats are compatible with the vast majority of 24V HVAC systems, which includes nearly all residential central air and heating systems installed in Las Vegas. Some older systems (millivolt systems, line-voltage baseboard heaters, or proprietary controls) may have limitations. Our technician checks compatibility before installation so there are no surprises.
Do you install thermostats for zoned HVAC systems?
Yes. Zoned HVAC systems use multiple thermostats — one for each zone — along with a zone control panel and motorized dampers. We install and configure thermostats for multi-zone systems, ensuring each zone operates independently and the control panel communicates correctly with all thermostats. This is especially common in two-story Las Vegas homes where upstairs and downstairs need separate temperature control.
My thermostat screen is blank. Do I need a new thermostat?
Not necessarily. A blank thermostat screen is often caused by dead batteries, a tripped HVAC breaker, a blown fuse on the furnace control board, or a loose wire. Try replacing batteries first. If the screen remains blank, check your electrical panel for a tripped breaker. If neither resolves it, call us for a diagnostic — it may be a simple wiring fix rather than a full replacement.
Does NV Energy offer rebates for smart thermostats?
NV Energy periodically offers rebates and incentives for qualifying smart thermostats and participation in demand response programs. Rebate amounts and availability change over time. We recommend checking NV Energy's current rebate page or asking our technician during your installation appointment for the latest information on available incentives.
