What our customers are saying

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!


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.


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.


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.


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

At Woodstock Heating & Cooling,

We’ll treat you like family.
