WiFi Thermostats and Smart Thermostats from Woodstock Heating & Cooling

As a longstanding HVAC contractor with over 100 years of experience, we definitely have seen everything when it comes to heating and cooling technology. Over the course of time, we have been able to adapt and evolve with modern technology and the latest trends, and we always put our customers first no matter what. This is why we are committed to providing our customers with exceptional service when it comes to installing and maintaining WiFI and smart thermostats.

Looking to Upgrade Your HVAC System?

One of the best advantages of using a smart thermostat is the ability to adjust your temperature control settings from essentially anywhere. Smart thermostats have the ability to learn your schedule and adjust your temperature control settings based on your schedule and habits. Regular WiFi thermostats are a little easier to use, however they don’t have the benefit of smart features such as geofencing, energy usage reports, and alerts for needed HVAC maintenance. If you are interested in learning more about WiFi & smart thermostats, give us a call today at (815) 338-0282 to schedule a free consultation!

What our customers are saying

Excellent experience. I had a humidifier, media cabinet, whole house dehumidifier and thermostat installed. Great experience from initial consultation with Thomas through quote and install with Witt. Witt did an excellent job- clean, efficient and took the time to explain everything to me. I would highly recommend Woodstock Heating and Cooling


responded to request for repair work on heating system quickly and the workmanship was excellent; along with reasonable cost. Woodstock Heating is a quality business; the Best!


Justin was excellent! He was professional, explained things so we could understand, he was thorough and did an excellent job on our preventative maintenance check for our heating systems. He is also very personable, honest and we are very pleased with his service!


Woodstock Heating and Cooling did a great job with both our furnace and A/C. When we have had any trouble, they respond very quickly. Their people are professional, caring and ready to go the extra mile to do what it takes to repair equipment. A big thank you in particular to Joe and Greg who were here last week to help with an issue caused by a mouse. We cannot say enough positive things about Woodstock Heating and Cooling! They have our loyalty!


Just so wonderful to work with a quality locally owned and operated company.


I have always been impressed by the prompt response and excellent service provided by Woodstock Heating & Cooling. Justin was here today for a service check on my furnace and he was extremely professional, informative and skilled…not surprising, because this is the company norm. Thank you.


Whit and KC were on time and completed the job well within the estimated time window. Great service, and I’ll call Woodstock Heating and Cooling again for future work on my HVAC.

At Woodstock Heating & Cooling,

We’ll treat you like family.
