What is Split-System AC?

Split systems are engineered to separate hot from cold temperatures. They’re central HVAC systems that consist of an indoor and an outdoor unit connected through ductwork, which circulates the cooled air through the structure. Split systems are energy-efficient and can be zoned, which gives you greater control over your utility consumption.

There are many benefits to choosing a split system for your home or business. They offer near-silent operation, which makes them ideal for homes, educational institutions, hospitals, and other buildings where keeping noise to a minimum is preferable. They are also energy-efficient and can be used to heat and cool the structure. Finally, split systems require minimal installation within structures that have existing ductwork, which makes them a cost-effective option for properties throughout the region. 

How is it Different Than Ductless Mini-Split Systems?

Split systems are centralized and connected to your ducts, whereas ductless mini-splits are positioned in strategic locations throughout the structure where they heat or cool the room where they’re installed. As with split systems, you can install multiple units if you desire zoning. However, this does require multiple indoor evaporator units that must be connected to the outdoor condenser. 

Expert Split-System AC Installation & Replacement

Our licensed and insured HVAC installers can help you select and install the optimal split system for your property. We will complete comprehensive load calculations to ensure proper sizing. We will consider every aspect in this regard, including the number of windows and their facing, insulation, construction type, room sizes, and more. Once the appropriate unit is selected, our installer will prepare the installation site, and we will install the system to the highest standards. When replacing your old system, we will safely remove it from the property and dispose of it in a code-compliant manner.

Most installations take between four to eight hours to complete. Prior to installation, we will provide you with an accurate timeline based on the size of your property and the complexity of the required preparation. Once installed, your new split-system air conditioner should provide anywhere from 10 to 20 years of reliable operation. This depends on how well the unit is maintained, prompt attention to required repairs, manufacturing quality, and of course, the quality of the installation itself. 

Prompt Split-System AC Repair Services

Prompt split system AC repairs are vital for your comfort and for preserving the energy-efficient operation of your split system. When issues are detected, we strongly recommend scheduling service before further damage occurs. Often, small problems can lead to expensive repairs that can easily be avoided by promptly repairing a minor issue. Some of the most common signs your split system requires repairs include:

  • Diminished heating or cooling capacity
  • Odd noises, including grinding, banging, hissing
  • Bad odors, including musty, moldy, or burning odors
  • Pooling water or visible leaks
  • Inconsistent temperature delivery
  • Rising energy consumption without change in habits
  • Weak airflow

Finally, if your system requires increasingly frequent or costlier repairs, we recommend exploring replacement options before a comprehensive system malfunction occurs.
