Central AC and Ductless AC: Which One Works Best?
All air conditioning units are designed to keep the home cool. However, not all AC units are the same. They differ in size, energy consumption, and design. When considering a new AC system, one may ask: “Which one works best for my home?”
Here, homeowners can learn about the differences between different types of AC units, from portable AC units to central AC. For more information on what AC system will work best for a home, homeowners should consult an experienced HVAC professional.
What Is Central AC?
Many new homes in the South come with central AC. Here, the air is cooled at a central location and distributed to different parts of the home via air ducts. These systems generally rely on ductwork and one or more blower fans to transport cool air. There are many benefits to central AC, including:
- Appearance: Central AC is generally installed in the home’s walls and ceilings, so homeowners don’t have to stare at ductwork all day.
- Lifespan: According to the U.S. Department of Energy, central AC systems generally last about 15 to 20 years.
- Consistent Temperature: A central AC cools the entire home at once and at a consistent temperature. This differs from window AC and portable AC units, which only cool one room or zone at a time.
A central AC system is ideal if a home already has ductwork. If not, homeowners should consider their other options.
What Are Ductless Mini-Split Systems?
Ductless mini-split systems are exactly what the name suggests: they’re AC systems that do not rely on ductwork. They’re ideal for homes that do not have pre-existing ductwork or the space to install them. Here’s what to know about them:
- Energy Savings: Ductless AC systems use less energy than central AC systems because they don’t experience energy losses due to air ducts. Also, when a homeowner isn't using a certain room, they can easily turn off the unit and conserve more energy.
- Indoor Air Quality: Ductless mini split AC systems are better for indoor air quality because air ducts can harbor dust, animal dander, and mold. Over time, this can cause respiratory problems. Because ductless AC systems don’t have ducts, they can’t spread dust and allergens that would accumulate in ducts.
- Less Maintenance: Ductless AC systems don’t require as much maintenance. Homeowners still have to change their system’s air filter at least every three months, like central AC units. However, they don’t have to get dirty air ducts professionally cleaned or ductwork fixed if there’s a leak.
Other Types of AC Units
Homeowners have other options besides central AC units and ductless mini-split systems. Some alternatives include:
- Air conditioning window units – AC window units generally keep one area of the home cool at once. The right window unit for one’s situation largely depends on the room they’re trying to cool. The larger the room, the more BTUs (British thermal units) the system will need.
- Portable air conditioning units – Portable AC units are good to use on an as-needed basis. Many of these systems come on wheels, making it easy to take the unit from room to room. They are useful for spaces like detached garages or workshops that don’t receive air conditioning.
