Boulder Residents: Take Your First Step in Home Automation

Did you ever wish that your home knew when to turn on its heating or cooling system without your intervention? Welzig Heating and Air offers smart thermostats that make this dream a reality. These thermostats incorporate information technology into their design, making them the latest technology in the HVAC industry. These devices use WIFI, have a color touch screen, use apps designed for Apple/Android OS, and can be remotely controlled whether you are at home or thousands of miles away.

Let Welzig Heating and Air Teach You the Benefits of a Smart Thermostat

Considering that smart thermostats can be more expensive than traditional ones, it is advantageous to know the benefits of smart thermostats so you are certain that you are getting the best deal. You can schedule your HVAC to run less while you’re out for the day with a smart thermostat. You can also program your smart A/C thermostat to start cooling your home just before your family arrives. With a smart thermostat, you can track your energy usage in real-time, resulting in lower bills. Smart thermostats can also be adjusted remotely. Smart thermostats have movement detectors that detect when family members are home and active. Using your family’s movement patterns, the thermostat learns when the house needs cooling or heating. In addition, smart thermostats are easy to install.

The team at Welzig Heating and Air consists of NATE-certified experts who will quickly identify the ideal thermostat for your home. We can improve the comfort and efficiency of your home together.

Satisfied Customers
They Speak For Us

Bob came out to look at our swamp cooler and was remarkably helpful and professional. Not only did he give me a knowledgeable diagnosis, but he also taught me a lot in the process. We’ll be calling him for all future needs with our cooling system.


Our 23-year-old A/C system ran out of “borrowed time” and became too difficult to continue maintaining. With great advice from Casey Welzig,, we replaced the old system with a Bryant Evolution A/C system. Max Loustaunau and Seth Bernhardt did an excellent job with removing the old system and installing the new one. Both of them are great to work with — very professional and very personable. We are really amazed at how much better the new system works!


Dave Kaplan-Gomez and James Miltersen installed my new Tankless Water Heater. Both were polite and professional. Care was taken not to damage anything in my house which I really appreciated. I use Welzig for all my HVAC needs and highly recommend them.
