What Are Ductless Split A/C Systems, and How Do They Benefit Your Business?

A commercial ductless split A/C system is ideal for cooling large spaces where running ductwork would be impractical or prohibitively expensive. Another excellent application is when you make additions to your property. Rather than installing ductwork and adding the extension to your existing HVAC system, many choose a commercial ductless split A/C system. Also known as “mini-splits,” these systems provide versatile climate control solutions, cooling specific rooms or “zones.” Some mini-splits also offer heating as well as cooling.

Commercial ductless split A/C systems include the following elements:

  • Outdoor Condenser Unit: Releases or collects heat, depending upon the time of year
  • Refrigerant Lines: Transport refrigerant between the A/C and the evaporator coil
  • Indoor Air Handlers: Mounted indoors, delivering cooled air to the blower

Commercial ductless split A/C systems include some of the latest HVAC technology. A mini-split is typically about 30% more energy-efficient than conventional cooling is. Although initially designed to cool a single zone, some commercial ductless split A/C systems can be programmed to cool multiple zones independently.

Common Issues with Ductless Split A/C Systems and How Aire Serv Can Help

Various issues can arise with commercial ductless split A/C systems. It can be disconcerting when this happens, as you rely on a working system to keep your business operating smoothly.

Indicators that your system is not running properly include the following:

  • Water Leaks: Water leaking from a mini-split indicates a blocked or cracked condensation line or drain.
  • Blowing Warm Air: If the air from your mini-split is no longer cool, a refrigerant leak may be present.
  • Excessive Noise: Commercial ductless split A/C systems are typically very quiet. If you notice unusual sounds, your system may need more refrigerant, a circuit board may have gone bad, or a sensor unit may need replacing.
  • High Indoor Humidity: A mini-split cools by removing moisture from the air. If your indoor humidity rises, it may indicate mold on the condenser line or that you need a larger unit.
  • Musty Smells: If your mini-split develops mold, leaks refrigerant, or has electrical problems, a bad smell is often the first sign.

As soon as you notice any of these signs of trouble, call your local Aire Serv. Our professionals are extensively trained and experienced in commercial ductless split A/C system repairs, and they will resolve the problems before they worsen.

Commercial Ductless Split AC System Services FAQs

As an industry leader and a brand trusted by homeowners and businesses nationwide for our knowledge and experience, we’re happy to answer your questions. Here are answers to some of the frequently asked questions about commercial ductless split AC system repair and replacement.

Commercial HVAC systems are a significant capital expenditure for businesses. In much the same way that you wouldn't buy an expensive vehicle and then forgo regular maintenance, purchasing an HVAC system and not maintaining it can be a costly mistake.

Regular maintenance extends the life of your ductless HVAC unit. It ensures optimum air quality by filtering out pollutants, and ultimately, it saves money by preventing costly breakdowns. Preventative maintenance includes a comprehensive inspection of the system and repair of minor issues before they become major ones, keeping your system running efficiently and trouble-free.

There are several energy efficiency upgrades for a commercial ductless air conditioner that can save energy and improve air quality. The following represent upgrades offering the greatest benefits:

  • Installing Air Economizers: An air economizer uses cool outdoor air to help reduce indoor temperature instead of running the compressor. It's an energy-efficient approach that also provides ventilation.
  • Ductless Energy Recovery Ventilation: This dedicated unit maintains a consistent flow of fresh air, helping create a healthier environment by offering an energy-efficient way to enhance indoor air quality.

There are several signs to look for that suggest your commercial ductless HVAC unit may need repairs. If it starts making unusual noises or you smell a strange odor, it's time to have it inspected. If your energy bill is increasing even though the weather and temperature have remained relatively constant, it may need a tune-up or could be experiencing a mechanical issue.

Any operational changes should also be red flags, signaling that you should have your system inspected before it breaks down. For example, the system might turn on and off more frequently, or you may notice uneven temperatures throughout the building.

There are various types of HVAC systems that can be used in commercial buildings. The best one depends on your unique situation and property. For instance, the "right" system is dependent on the size of the building, the climate, your budget, and your specific heating and cooling needs. Professional HVAC companies like Aire Serv can recommend the best HVAC system for your commercial property’s unique needs and budget.

The following are some of the best types of HVAC systems for commercial buildings:

  • Single-Split System: A commercial ductless split system offers a cost-effective approach for smaller commercial spaces.
  • Multi-Split System: Ideal for midsized properties, these systems provide multiple ductless HVAC units that work together.
  • Variable Air Volume System: Designed for large buildings, these systems meet the different airflow and temperature needs in the various building zones.
  • Variable Refrigerant Flow System: This system operates like a ductless mini-split system. It uses refrigerant and is highly efficient.

The U.S. Department of Energy often releases new energy regulations targeted at reducing pollution and energy consumption. The latest regulations require your system to have specific HVAC efficiency ratings, depending on where you live. In addition, the 2025 refrigerant mandate requires HVAC systems sold after January 1, 2025, to use refrigerants with a lower global warming impact.

While you do not have to replace your existing unit, meeting these regulatory changes for any new installations or upgrades is required. Contact a licensed local HVAC service provider like Aire Serv to ensure you remain in compliance.

A building's energy rating measures its energy efficiency. The ENERGY STAR® score compares your building’s energy consumption to similar buildings’ energy consumption. By replacing less efficient HVAC units with newer, energy-efficient models, you can significantly improve your facility's rating.
