Forced-air central HVAC systems are the most common type of comfort system across the country, but they're not always the most efficient. If you're remodeling, designing a new home or simply in need of supplemental cooling and heating, consider going ductless for superior comfort and energy savings.
Common Ductwork Problems
Ductwork systems are generally fabricated from thin sheet metal and sometimes installed in unconditioned areas of the home. Temperatures in these zones, such as crawl space, basement and attic, can reach extremes, resulting in heat gain/loss through metal duct walls and uneven temperatures in the home.
More energy may be wasted to ducts that are poorly installed, aging or damaged. In fact, Energy Star states up to 30 percent of cooled and heated airflow is lost through leaks and holes, and more energy is wasted via conduction.
The mainstay for residential ductless cooling and heating is supplementing the primary comfort system in retrofits, room additions and specific zones. However, more homeowners are discovering ductless systems are ideal for multiple zones and green, energy-efficient whole-home cooling and heating. Here's why:
- Efficiency - Select ductless systems easily beat conventional central systems, electric furnaces, electric baseboard and ceiling heat.
- Zoned comfort - Each air handling unit (AHU) of a ductless multi-split system comprises a zone with independent temperature control, which allows homeowners to cool and heat zones as needed to save energy.
- Versatile configurations - Ductless multi-split systems may connect up to five indoor AHUs to each outdoor unit. Mitsubishi Electric ductless systems offer the only two-piping configuration for simultaneous cooling and heating.
- Multiple mounting options - Each AHU may extend up to 100 feet from the outdoor unit. This provides multiple locations for the air handling unit and outdoor unit. The AHUs may be mounted, recessed or concealed on or behind the surfaces of walls, ceilings and floors.
- Indoor air quality - Air handlers with three-phase air filtration act as room cleaners.
