Commercial HVAC Services

W. L. Gary Company cares about your comfort, your investment in your building, and your building’s efficiency.

Comfort.  Whether you are running your AC or heat, the temperature in your space should be comfortable. You should have good indoor air quality with an appropriate mix of indoor and outdoor air through proper ventilation.

Investment. Your HVAC systems require a financial investment, whether you are a building owner who has paid for the installation and upgrade of HVAC systems, or are a tenant who is paying for your energy use.  W. L. Gary helps our clients get the most out of their heating and cooling equipment.   Several ways we achieve this are by:

  • Assisting clients in selecting the system that is best for their needs
  • Maintaining systems after installation
  • Repairing neglected equipment to restore it to proper operation
  • Maintaining existing equipment

Proper HVAC system sizing and maintenance helps your equipment last longer and keeps energy costs at reasonable levels.

Efficiency.  Energy efficiency of your HVAC systems is important in reducing your operating expenses.  W. L. Gary Company can help keep your current systems running efficiently as possible with proper maintenance and operational tips.  We will evaluate your current energy use and help you identify ways to save energy, and therefore operating costs, without sacrificing comfort.
