- Ductless systems are more expensive than central air upon installation.
- However, due to their energy efficiency, they actually save you money in the long run.
- Because ductless systems allow you the option of zoning, you have more control over how much energy is spent cooling each room.
Besides, What are the pros and cons of a ductless air conditioner? The Pros and Cons of Ductless Mini-Split AC
- Pros. Its small size and flexibility make it a great choice for single rooms or add ons, especially where ducts may not be an option. …
- Cons. As an initial investment, they’re not cheap. …
- The Long Run. Sure the price tag is steep, most initial investments are like that.
How many rooms can a ductless AC cool?
Both can be used to cool a single room without ductwork. But a mini-split can add more evaporator units (up to 4) to one condenser unit. So technically it can cool up to 4 rooms.
How long do ductless systems last? Ductless mini-splits – Like heat pumps, ductless mini-splits can provide both heating and cooling, with a typical life span of 10 to 30 years, except in coastal areas.
Hence, Does every room need a ductless unit? Do I Need a Ductless Unit in Every Room of the House? No. While you won’t need a single indoor unit for every room in the home, the outdoor unit does attach to multiple indoor wall-mounted units. In most homes, this typically means having indoor units in main living areas.
How many square feet Can a ductless air conditioner cool?
A large ductless system with a BTU of 36,000 can effectively cool a room measuring up to 1,500 total square feet, while smaller units usually start at around 9,000 BTUs and can cool approximately 350 square feet of space (the size of approximately 2-3 bedrooms).
What is the difference between ductless and mini split?
Typically, only one thermostat is used for the entire system, although zoning technology can be utilized. Central systems can run off electricity or gas. Conversely, ductless mini-split systems don’t use ductwork to move air throughout your home.
How many ductless units do I need?
Based on the size of your home, calculate the BTU requirements (primary factor). Usually, we use a 20 BTU per sq ft rule of thumb. Example: For a 1,500 sq ft home, you would need 1,500×20 = 30,000 BTU output. You can use one 30,000 BTU mini splits, two 15,000 BTU mini splits, or three 10,000 BTU mini splits.
How do you install a ductless air conditioner?
Are ductless air conditioners easy to install?
Generally speaking, it’s much easier to install a ductless mini split air conditioner compared to the process of installing a standard AC system. Not only do you not need to add duct work, but the hook up between the exterior and interior units requires nothing more than a three-inch hole through your wall.
How many mini splits do I need for a 1500 square foot house?
BTU Sizing Chart for Mini Split Systems
| Area To Be Cooled | Capacity Needed (BTUs Per Hour) |

| 700 to 1,000 square feet | 18,000 BTUs |
| 1,000 to 1,200 square feet | 21,000 BTUs |
| 1,200 to 1,400 square feet | 23,000 BTUs |
| Up to 1,500 square feet | 24,000 BTUs |

How long do ductless air conditioners last?
When adequately maintained, it’s estimated that most mini split ductless air conditioners last for about 20 years. This is far beyond the 12 to 15 years that most conventional systems last, so it’s fairly safe to assume that your mini split system will last longer than most other options.
Can ductless AC cool a whole house?
Even though it takes a powerful system – especially in a large home – a ductless mini split is up to the task. With the right size system in place, it’s capable of cooling an entire house, from the basement all the way up to the attic.
Do ductless air conditioners need to be vented?
Since the compressor sits outside, ductless split air conditioners are very quiet and efficient. The indoor units do not need to vent through an exterior wall, so ductless splits are a good option to cool rooms with no windows and no exterior walls.
Do ductless air conditioners really work?
Energy efficiency: Ductless systems don’t lose hot or cold air due to duct leakage. Most mini split systems are approximately 20 to 30 percent more efficient than ducted systems. Multi-purpose: Mini splits also offer dehumidifying and air purifying benefits.
Should I leave my ductless AC on all the time?
Let your system run continuously. A mini-split system uses less energy and keeps temperatures most consistent when it runs continuously, as in, 24/7.
Do mini splits get mold?
Having mold in your ductless mini split unit is a disgusting problem, and unfortunately, a rather common one. Ductless Mini Split systems can be filled with dirt, debris, and mold if they are not properly maintained. Left ignored, the inside of your ductless mini split could become a home for mold and mildew.
What size AC do I need for 1500 square feet?
Therefore, if your home is 1,500 square feet, your air conditioning unit should be 3.5 to four tons.
