Lisa E. Crosley, President, EnviroControl Systems, shares the advantages and disadvantage of most commonly used commercial HVAC systems.

Unlike traditional HVAC mechanical companies, EnviroControl Systems’ decades of design-build and value engineering experience brings a wide variety of choices to building owners.

Modern commercial HVAC systems fall into basic categories, each offering distinct advantages and disadvantages.

VRF Technology

Although the last to enter the American market, VRF technology is rapidly overtaking the commercia/industrial HVAC market through its sophistication and ductless capacity. Initial investment may be more costly, but VRF units offer ROI through energy efficiency, quiet operation, and compatibility with modern building design and environmental standards.

Commercial Package Units

Commercial Package Units offer space efficiency, ease of installation, and lower installation costs. Maintenance over time is streamlined since all components—compressor, condenser, and evaporator—are housed in a single unit.

Package units may be placed on either a roof-top or a ground-level concrete pad, and are particularly useful in large commercial applications.

On the downside, Commercial Package Units limit customization, may be noisier when operating, and may not be the best option for all applications.

Split Systems

Considered the workhorse of commercial HVAC systems, split systems consist of two main components: an outdoor unit with a compressor and condenser, and an indoor unit with an evaporator coil and blower.

Split systems are commonly used in both residential and small commercial applications.

Split systems offer the advantage of affordability, relative ease of installation, and customization for a variety of climate control demands.

Thinking Outside the Box

EnviroControl Systems offers building owners and developers options outside standard units.

Geothermal Systems put the Earth’s constant temperature to work to heat and cool buildings. Initial cost of a geothermal system is higher and adequate space is required to bury pipes underground. However, ROI is estimated at about 5 years: units are energy efficient, support reduced operating cost over the lifetime of the equipment, and last longer than standard equipment.

Chilled Water Systems circulate chilled water through pipes to cooling coils in air handlers or fan coil units. These systems are especially effective for office complexes, hotels, hospitals, and other large buildings.

Hybrid Systems combine two or more types of HVAC systems. Working EnviroControl Systems’ experienced team, new construction, building retrofits, tenant buildouts, and historic reuse projects can achieve the advantages of a variety of systems, while diminishing product disadvantages.
