Our History

Founded in 1850 as Whitson’s Tin & Hardware Store, Woodstock Heating & Cooling has been serving the community for over 170 years. Originally focused on selling and installing Home Guard wood-burning stoves and flue material, the business evolved over time under the united vision of numerous owners to become the trusted heating and cooling service provider it is today.

In 1917, the family-owned store was acquired by Frank Czadek, who breathed new life into the business by renaming it Woodstock Heating. Today, it is proudly owned and operated by the Iversen Family, who are deeply invested in continuing the legacy of excellence and trustworthiness.

The husband-wife duo of Eric and Dawn work tirelessly in the business every day, providing top-notch services to their valued customers. By prioritizing honesty and treating each individual as family, be it a customer or employee, Woodstock Heating & Cooling has earned the respect and appreciation of the community it proudly serves. Since the Iversen’s have come into ownership of Woodstock Heating & Cooling in 2016, they have grown the business by over 400% which is simply due to the commitment to their core values and how they run their business.

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


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.


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!


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


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!


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!


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.
