Energy Efficient Solutions for HVAC Design, Tenant Improvement, New Construction, Equipment Replacement

At Five Star Mechanical, it's our goal to give you better control over managing your facility's energy consumption, ensure occupant comfort, and provide optimal indoor air quality. Whether it is new construction, a tenant improvement, or the replacement of existing equipment, we can custom design and install a state-of-the-art HVAC system that is tailored to your budget and facility's needs. If it is time to upgrade or replace your property's HVAC system, we can explore options with you, make recommendations based on our extensive knowledge of the latest technology, and perform the installation.

Control Systems & RTU Tune Up

We can service your existing BAS (Building Automation System) control system or design and install a new one that better suits your needs. Advancements in technology have made these new systems easier to install, operate, and maintain, improving the operation of your facility and reducing your energy consumption. United States Department of Energy and ASHRAE both agree that "retrofit commissioning" of an HVAC roof top unit (RTU) is possibly the most cost-effective expenditure a business owner can make to save money and lower energy demand. An RTU tune up from Five Star Mechanical will get your equipment as close to factory specs as possible and lower your energy costs.
