Delivering the Highest Quality in Commercial HVAC Services


At Sobieski, we have been installing, servicing and repairing HVAC systems in commercial properties for over 30 years.

Commercial Heating & Cooling

Commercial heating, cooling and ventilation is a complex, intricate process that has to be done right. Due to the unique nature of commercial buildings, we take the time to design an HVAC system specific to your requirements and needs. Our goal at Sobieski is to ensure everything is up to code and comfortable for the building’s occupants long into the future.

Commercial HVAC Repair & Maintenance

We're proud to be a Linc Service contractor. We follow the disciplines of the Linc System in delivering the highest quality preventive maintenance and service for heating, ventilation and air conditioning systems.

Our years of experience have yielded a team of professionals capable of providing the level of service that you expect. Our primary focus is to keep your business running smoothly with lowered operating costs, keep your system online and provide comfort for your customers and employees.

We also offer commercial HVAC service agreements which fit your building’s needs specifically. Since typical HVAC systems lose about 5% of their operating efficiency for every year that they aren’t maintained, you could be losing a lot of money by not servicing yours properly. Sobieski experts will design a plan to ensure your systems are regularly maintained for optimal efficiency, comfort and savings.

At Sobieski, there is no “one-size-fits-all” mentality. We take the time to listen to determine exactly what you want and need. We then use our experience to determine the best course of action to alleviate your problems. Our recommendations will help you understand the short-term and long-term costs and benefits of making strategic upgrades to your commercial HVAC systems.
