Different Types of Thermostats We Install
There’s not just one type of thermostat out there. Whether you’re planning to install a new HVAC system or replace an old one, the right thermostat makes a significant difference in comfort, energy savings, and control.
Smart Thermostats
Smart thermostats are the most advanced option on the market. They learn your temperature preferences and daily habits to adjust settings and reduce energy waste automatically.
You can control them remotely using a smartphone or voice assistant, and many models monitor humidity and indoor air quality.

Manual Thermostats
Manual thermostats are the simplest type. They allow you to adjust the temperature using a physical dial or slider. While lacking modern features like scheduling and remote access, manual thermostats remain a reliable choice for basic heating and cooling systems.
They’re often found in older homes or used in rooms where advanced features aren’t necessary.
Programmable Thermostats
Programmable thermostats enable you to create customized heating and cooling schedules tailored to your lifestyle. You can set different temperatures for weekdays and weekends, which helps reduce energy waste when no one’s home.
If you want more control without investing in smart tech, a programmable model offers a practical and affordable middle ground.
Wi-Fi Thermostats
Wi-Fi thermostats offer the convenience of mobile access without all the learning features of smart models. You can adjust temperatures, set schedules, and receive alerts from your phone or tablet. They’re a great fit for those who want remote control and energy monitoring features without automation.
How Do I Know If I Need a New Thermostat?
What can seem like a major HVAC issue is often the fault of a failing thermostat. If your system isn’t responding correctly, a thermostat replacement might not only solve the problem fast but also save on maintenance costs.
If you see any of the following signs, it’s time to upgrade:
- Home is too hot or cool, even after adjusting
- Screen display is unresponsive or completely blank
- Heating or cooling cycles are unusually short or frequent
- A noticeable delay between setting changes and HVAC response
- Uneven heating and cooling throughout the home
- Sudden energy bill spikes
- Your thermostat is over 10 years old or uses outdated tech
While many of these are common, they don’t always mean a thermostat repair or replacement is necessary. Contact an HVAC expert from Dauenhauer for a professional inspection and expert recommendation on which choice is the right fit for your home.

Thermostat Installation FAQ
Why Can’t I Change the Temperature on My Thermostat?
If your thermostat won’t respond to changes, the issue could be as simple as dead batteries or a locked setting. In other cases, wiring problems or sensor failures can prevent the system from registering commands. For programmable or smart thermostats, connectivity issues may block app controls.
If you’re unsure what’s causing the problem, our team has you covered. We guide you through the basics of thermostat wiring, including wire color codes and what they mean.
Why Is My Thermostat Not Working?
The most common issues include disconnected wires, tripped breakers, faulty sensors, or outdated firmware. Certain smart thermostats can stop functioning if your Wi-Fi drops or a software update fails.
If your thermostat’s screen is completely blank, power loss is the likely culprit. While some issues are DIY-friendly, specific problems require professional inspection and repair, especially in cases of direct issues with your HVAC.
How Much Does It Cost to Replace a Thermostat?
The cost of a thermostat installation service relies on several factors, including the type of thermostat chosen, any necessary wiring upgrades, and the complexity of the installation.
Manual and programmable thermostats are typically less expensive, while smart thermostats with advanced features will have a higher upfront cost.
