Most commercial AC units should be serviced at least twice a year—once before cooling season and once before heating season (if applicable). Preventive maintenance includes filter changes, coil cleaning, refrigerant checks, and control calibration, and it helps reduce energy use, extend system life, and avoid unplanned downtime.

Yes. ETS proudly provides commercial AC repair and maintenance in Columbus, Ohio, and the surrounding areas—including Lewis Center, New Albany, Westerville, Gahanna, Worthington, and Dublin. Whether it’s an emergency repair or scheduled service, our team responds fast to keep your building cool and operational.

Commercial AC systems are built for larger spaces, higher occupancy, and more demanding loads. They often include components like chillers, cooling towers, VRF systems, or rooftop units, and require expert configuration for zoning, ventilation, and energy efficiency. Residential AC is simpler and serves a smaller, more predictable environment.

If your commercial AC system isn’t keeping up, watch for these signs of underperformance:

​

• Uneven temperatures across different rooms or zones

• Loud operation or excessive vibration

• Rising energy bills that don’t align with usage

• Short cycling (frequent on/off operation)

• Humidity problems or poor dehumidification

These symptoms often mean your commercial AC unit is too small, outdated, or operating inefficiently—and may need service, upgrades, or replacement.

Yes — and the distinction matters:
 

Comfort Cooling

• Cools air for people

• Focused on occupant comfort

• Used in offices, retail, hospitality

Process Cooling

• Controls temps for machinery or materials

• Essential for productivity and product quality

• Used in manufacturing, data centers, and labs

ETS designs and services both types with equal expertise.

Commercial cooling systems regulate temperature in larger or high-occupancy buildings by extracting heat from the air or processes and moving it outdoors. Unlike residential AC, these systems are engineered for durability, zoning, and constant uptime.
 

Common components include:

• Compressors, evaporators, condensers

• Chillers or rooftop units

• Smart controls and zoning dampers

• Ducted or ductless delivery systems

There are several types of commercial cooling systems designed for different building layouts and operational needs.

​

Common commercial cooling systems include:

​

• Rooftop Units (RTUs): Ideal for single-story buildings such as retail stores and warehouses. These packaged systems combine cooling and air handling in one rooftop unit.

• VRF Systems (Variable Refrigerant Flow): Well suited for multi-zone buildings like offices, hotels, and multi-tenant spaces, allowing independent temperature control across different areas.

• Chillers: Used in large facilities such as hospitals, universities, and manufacturing plants. Chillers circulate chilled water to air handlers or fan coils throughout the building.

• Ductless Mini-Splits: A flexible solution for small offices, server rooms, or retrofit projects where installing ductwork is difficult.

• Process Cooling Systems: Designed for industrial environments that require precise temperature control of equipment or materials.

• Glycol Cooling Systems: Used where freeze protection or stable process temperatures are required, commonly in industrial and refrigeration applications.

Proper system sizing is critical for performance and energy savings.

At ETS, we calculate:

• Square footage

• Heat loads from lighting, people, equipment

• Sun exposure and window placement

• Building insulation and air leakage

We never guess—we engineer the solution.

Zoning allows different areas of your building to receive different levels of cooling.

Benefits include:

• Tailored comfort for each department or room

• Reduced energy use in low-traffic zones

• Smarter scheduling with programmable controls

• Greater occupant satisfaction

ETS integrates zoning into new or existing systems using BMS platforms like BACnet and Prolon.

Yes — managing humidity is one of the core functions of a commercial AC unit. In addition to cooling the air, these systems extract excess moisture to improve comfort and air quality.

​

At Engineered Temperature Solutions, we optimize your commercial cooling setup with:

• Advanced coil configurations that enhance moisture removal

• Variable-speed fans that increase runtime for better dehumidification

• Supplemental dehumidifiers for high-humidity spaces like gyms, kitchens, and production areas

Controlling indoor humidity helps prevent mold, improve occupant comfort, and protect your equipment.

It depends on the type and usage:

• Rooftop units: 15–20 years

• Chillers: 20–25 years (well maintained)

• VRF and ductless systems: 15–20 years

• Controls and sensors: 7–10 years

Preventive maintenance can extend lifespan significantly.

Yes — upgrading your commercial AC unit in Ohio may make you eligible for valuable rebates and tax incentives.

Qualifying upgrades can include:

• Commercial HVAC rebates from AEP Ohio and Columbia Gas

• Federal tax deductions under Section 179D for energy-efficient systems

• Manufacturer or utility rebates for approved commercial AC units

Engineered Temperature Solutions can help you navigate rebate programs and ensure your new commercial AC unit meets all incentive requirements.
