Ductless AC
Ductless mini-splits provide a convenient and unobtrusive way to add air conditioning to spaces like additions, sunrooms, finished basements, attics and garage workshops. They can even serve as a primary system in homes in mild climates.
Unlike traditional central air Mini Split AC systems, which rely on ductwork to deliver conditioned air throughout the home, a ductless system uses a series of indoor air handling units connected to an outdoor condenser via a series of pipes. Each unit can have its own thermostat, so you can control the temperature of just that space.
One advantage of this design is that ductless systems avoid the energy waste that comes from old, leaky ductwork. That can account for up to 30% of a central air conditioner’s energy consumption, as well as contributing to poor indoor air quality and increased allergy symptoms.
Mini splits also use advanced technology to save energy, including inverter-controlled variable speed operation, which adjusts the amount of power the system uses to match changing conditions and temperature needs. That lowers energy consumption and wear on fans, compressors and other components. Regular maintenance is also important. It’s essential to clean the air filter monthly and keep the indoor unit free of dust and debris.
If you’re considering a ductless air conditioning system for your home, it’s important to work with an HVAC contractor who has extensive experience with this type of equipment. A knowledgeable professional can help you choose the right size and capacity system to meet your specific needs, and they’ll ensure that each component is properly installed for peak performance and longevity.
Other advantages of a ductless system include the fact that it doesn’t require ductwork, and it can often be less expensive than installing or repairing a duct system. Additionally, it can be a great solution for period homes, since it doesn’t put the integrity of original features at risk.
Finally, a ductless system can be more convenient to operate than a window or portable AC. Its controls are typically mounted in a wall or ceiling, making them more out of sight and out of mind. They’re also usually quieter and more efficient than their portable counterparts, and can provide better comfort over a wider range of temperatures.
While some ductless systems require 208-230 volt service, others can run on standard household electric. It’s best to consult with an HVAC contractor to see if your house’s current electrical panel and wiring can support the system. It’s also possible to install a ductless system in a new construction or remodeling project, but this can be more costly.
