Upgrading your thermostat can transform the comfort, efficiency, and convenience of your home’s heating and cooling system. Whether you’re considering installing a new smart thermostat yourself or leaving the job to a professional, it’s essential to understand your options, the benefits, and the potential risks. In this guide, we’ll walk you through everything you need to know about thermostat installation and help you make the right decision for your home.

Why Upgrade to a Smart or Programmable Thermostat?

Improved Energy Efficiency

Switching from a traditional thermostat to a programmable or smart thermostat can significantly lower your heating and cooling bills. The U.S. Department of Energy estimates that adjusting your thermostat by just one degree can reduce your energy costs by around 1%. With a programmable or smart thermostat, you can schedule temperature changes that automatically lower or raise the temperature while you’re away or asleep—leading to substantial monthly savings.


Greater Convenience and Control

Smart thermostats connect to your home’s Wi-Fi network, allowing you to adjust the temperature from anywhere using your smartphone or a compatible virtual assistant like Amazon Alexa or Google Assistant. No more getting out of bed to turn up the heat or walking into a too-hot house after a vacation—simply open an app or use voice commands.


Enhanced Monitoring

If you own a second property or spend long periods away from home, a smart thermostat lets you monitor and control heating and cooling remotely. You can check your home’s status at any time, receive alerts if the temperature drops too low, and even make instant adjustments to avoid potential HVAC issues.

Installing a Thermostat Yourself: What to Expect

If you’re handy with basic home improvement tasks and have confidence working with wiring, installing a thermostat yourself can be a manageable project. However, be sure to review these important considerations:

  1. Evaluate Thermostat Placement

    • Before removing the old thermostat, think about whether you’re satisfied with its current location. If the existing thermostat is in a spot that doesn’t reflect your home’s average temperature—such as near a heat source or in direct sunlight—you may want to move it. Relocating a thermostat involves more than a simple replacement, so you may need professional help.
  2. Turn Off Power to the HVAC System

    • Safety is crucial. Switch off power to your furnace and air conditioning system at the breaker box to avoid electrical hazards.
  3. Check the Wiring

    • Only Two Wires? Your existing thermostat isn’t wired to a power source. Newer thermostats will require a battery-powered solution.
    • More Than Two Wires? Your new thermostat is likely powered directly by your HVAC system. You’ll need to know which wire connects to which terminal—if you’re uncertain or uncomfortable, hiring a professional is recommended.
  4. Follow the Manufacturer’s Instructions

    • Smart thermostats often come with detailed setup guides. Ensure you understand every step, from mounting the backplate to configuring Wi-Fi settings.

Hiring a Professional for Thermostat Installation

Not everyone feels confident dealing with electrical wiring or relocating thermostats. In these cases, hiring a professional HVAC company like Energy Savers can save you time, prevent damage, and ensure your new thermostat runs optimally. Here are a few reasons you might prefer professional assistance:

  1. Moving Your Thermostat

    • If certain rooms in your home are too hot or too cold compared to the thermostat reading, placement could be the issue. Moving a thermostat to a different area requires running new wires and drilling holes—tasks best left to professionals who can ensure everything is done correctly.
  2. Preventing Warranty Issues

    • Some thermostat manufacturers require a certified HVAC technician to perform the installation. Failing to follow these guidelines could void your warranty, leaving you liable for any future repairs or replacements.
  3. Avoiding Costly Mistakes

    • Incorrect wiring can lead to system malfunctions, poor efficiency, or even electrical hazards. By working with experienced technicians, you can ensure your HVAC system stays safe and efficient.
  4. Fast, Reliable Service

    • A trained professional has the knowledge to install your smart or programmable thermostat quickly and accurately the first time—so you can begin reaping the benefits right away.
