High-Velocity Heating and Air Conditioning System Services from Woodstock Heating & Cooling

One area where we particularly excel happens to be high-velocity HVAC systems. These systems utilize smaller ducts and achieve much higher airflow rates to provide exceptional temperature control in your home. The installation of these systems is easier compared to traditional systems as the small flexible ducts can be snaked through some of the smallest spaces, making these systems incredibly versatile. These systems are great for older homes that have no space for traditional ductwork and are also wonderful for any home because of their high level of energy efficiency. They’re also great for aesthetic purposes as the vents are hardly visible, yet provide a comfortable environment for your space.

Call on the Experts to Handle Your High-Velocity HVAC Repairs, Maintenance, and Installations

Our NATE-certified professionals are equipped to install, repair, and maintain high-velocity HVAC systems. Our installations are second to none and we’ll make sure you have a system designed to meet your comfort needs and budget. When you work with us, we’ll treat you just like family and keep you informed throughout your new installation project. If you are interested in the benefits of high-velocity HVAC systems or need maintenance, give us a call at (815) 338-0282 today!

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!


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


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!


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.


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!

At Woodstock Heating & Cooling,

We’ll treat you like family.
