H1: Common Types of HVAC Systems for Commercial Buildings
Every commercial building depends on a reliable HVAC system to maintain comfort, control indoor air quality, and manage energy costs. Choosing the right system depends on your building's size, layout, and specific heating or cooling requirements.
The experts at Estes Services break down the most common types of HVAC systems for commercial buildings, including split systems, rooftop units, VRF systems, and chillers — and explain how to find the best commercial HVAC solution for your property.
H2: Single-Split System
A single-split system is one of the simplest and most common types of commercial HVAC systems. It features an indoor unit (air handler and evaporator coil) and an outdoor unit (compressor and condenser). Together, they regulate the temperature in a single zone of your building.
This system is ideal for small offices, retail stores, and restaurants where zoned comfort is essential. Each unit operates independently, which helps maintain consistent heating and cooling across smaller areas.
However, single-split systems are designed for one space at a time, so larger buildings may require multiple installations. Distance between indoor and outdoor components should also be minimal to ensure efficiency.
For expert single-split system installation, contact Estes Services today — our licensed technicians can design a tailored solution that fits your building.
H2: Multi-Split System
A multi-split system builds on the same concept as a single-split but connects multiple indoor units to one outdoor unit. This design allows several zones or rooms to be heated or cooled simultaneously from one system, saving space and reducing energy costs.
Multi-split systems are ideal for office suites, small hotels, and light commercial properties that require flexible temperature control. Each indoor unit can be adjusted separately, improving comfort across multiple spaces.
Compared to ductless mini split systems, multi-splits offer better efficiency for medium-sized buildings with different comfort needs. If your goal is to improve performance while minimizing visual clutter, this system may be the right choice for your commercial HVAC solution.
H2: VRF System (Variable Refrigerant Flow)
For large commercial properties with multiple floors or zones, a VRF system delivers superior flexibility and efficiency. It uses variable refrigerant flow to simultaneously provide heating or cooling to different zones as needed.
A single modular VRF unit can connect to as many as 64 indoor units, operating on a two-pipe design that simplifies installation and maintenance. This system ensures proper ventilation and air conditioning, reduces downtime, and improves energy savings.
VRF systems are especially suitable for office buildings, hotels, schools, and medical facilities that require quiet operation and consistent comfort.
Estes Services specializes in commercial HVAC services across Metro Atlanta and can customize a VRF design that supports your building today and scales for the future.
H2: Rooftop Units (RTU) or Packaged Systems
Rooftop units (RTUs) — also known as packaged systems — are among the most common HVAC setups in large commercial and industrial spaces. These self-contained systems combine the heating, ventilation, and air conditioning components into one unit, typically installed on the roof or ground level.
RTUs work well for single-story buildings such as shopping centers, warehouses, and department stores. They are easy to install, maintain, and repair since all HVAC equipment is centralized.
Because of their accessibility, RTUs make it simple for technicians to perform maintenance, ensuring minimal disruption to your business operations. Estes Services offers cost-effective RTU installation and maintenance options — schedule service today to get started.
H2: Chiller Systems
Chiller systems are the powerhouse of large-scale heating and cooling systems. They move warm air from one area to another, cooling large volumes of air for expansive facilities like hospitals, factories, and universities.
There are two main types: water-cooled and air-cooled chillers.
Water-cooled chillers are typically installed in basements or mechanical rooms.
Air-cooled chillers are placed outside or on rooftops for easy access and maintenance.
Chillers act as centralized air conditioning systems that improve efficiency and reduce the number of refrigerant lines running through a building. While the upfront cost is higher, the long-term energy savings and durability provide a strong return on investment.
These systems can be paired with air handlers, ceiling units, or other ventilation equipment to maintain comfort and ensure proper airflow throughout the building. For a fully integrated design, contact our commercial HVAC installation experts for a consultation.
