Commercial Heating & Furnace System Operation

Commercial heating systems are essential for maintaining comfort and protecting your building and its contents from the elements. A properly functioning furnace ensures proper temperature and humidity control, thus preserving everything from electronics and files to furniture and artwork.

While our winters are generally mild, temperatures from December through February can hover just above freezing. Your furnace offers the protection you need to properly maintain your building and ensure the comfort and safety of employees and visitors.

Commercial Furnace Repair vs. Commercial Furnace Replacement

We recommend repairing your unit as long as the system can be reliably repaired using a cost-effective solution, such as a component replacement, system adjustment, upgrade, etc. Ultimately, it’s best to keep your furnace operational for as many years as possible.

However, replacement is the best solution if your system:

  • Is 15 to 20 years old. The older the system, the more frequent and costlier the repairs. Older furnaces are also less efficient, which can increase your monthly utility bills.
  • Shows signs of significant wear and tear
  • Requires frequent, complex, and expensive repairs
  • No longer meets the heating needs of your property

Frequently Asked Questions

How often should I schedule commercial heating maintenance?

Commercial heating systems require routine maintenance to operate reliably and maintain the manufacturer’s warranty. Scheduling heating maintenance once a year, in the fall, can reduce the risk of premature breakdowns and expensive repairs. Heating systems that get expert care every year operate more efficiently, which can reduce monthly utility costs.

Will a larger heating system provide more heat?

When selecting commercial HVAC systems for your facility, choosing the correct size and capacity is vital. An improperly sized system, whether too big or small, will operate inefficiently, resulting in skyrocketing utility costs and unreliable comfort.
