Are Ductless Mini Splits Loud?

In most cases, single-room cooling solutions are rather loud. This is why when homeowners are told about ductless air conditioning and heating systems, we often get questioned about the level of noise ductless mini-split exert. 

Fortunately, ductless mini-split air conditioners exert the same noise level as any typical standard air conditioner.

Is Ductless Mini-Splits Quieter?

Ductless mini-split systems’ heating and cooling work a lot differently than every other air conditioner. Ductless mini-split has an outdoor unit, just like every other conventional split system.

However, a part of the ductless mini-split air conditioner sits outside while a refrigerant line leads to the indoor blower units.

These units blow directly into your room and cool your room entirely. So, as you can already guess, the loudest component, the ductless mini-split, remains outside.

Reasons To Switch To Ductless Mini-split 

There are many reasons to switch to ductless mini-split. Here are a few reasons to switch to ductless mini-split air conditioners :

  1. High rating inefficiency

Ductless mini-split heating and cooling systems are a lot more efficient than portable heaters or window Air conditioner units. Unfortunately, most systems are not held to the same efficiency standards as conventional central air units because it is difficult to manufacture them using little energy.

However, ductless mini-split air conditioners are different, and they are the most efficient central air conditioning systems.

  1. Cooling and heating

Ductless mini-split air conditioners provide heating and cooling in one because they have heat pumps. Heat Pumps help move the heat.

  1. Renovations are unnecessary

You can own up to 4 indoor units controlled by the same thermostat in almost all setups. This means you can do whole-house heating and cooling without significant renovations to your house.

These are why switching to ductless mini-split air conditioners is an excellent idea.

Like every other product, ductless mini-split air conditioners also have a ton of advantages. These advantages are given below :

  1. Small size and flexible zoning

Ductless mini splits are small, and they offer a ton of flexibility in terms of zoning. Various brands and models are often available with up to four indoor air distributing and handling units, each of which is connected to a single outdoor unit and compressor.

These four units can cool four different rooms. Each room has a separate thermostat for easy temperature adjustment. In addition, the indoor air handling units can be re-adjusted to provide cooling for other rooms.

  1. Easy installation

Ductless mini-split air conditioners are very easy to install. The connection between the indoor and outdoor system units can be accomplished with the help of a conduit inserted in a three-inch hole through the width of a wall.

The manufacturing companies can supply you with the type of conduit you need. That way, you can place your outdoor unit almost 50ft away from the indoor unit. This is incredibly helpful when homeowners want to install the compressor/condenser unit on an exterior sidewall of a building while the  cooling rooms are located in the front or back areas of the home.

  1. Energy efficient

Ductless mini-split air conditioners don’t experience the same degree of energy loss as typical air conditioners. Energy losses because of ductwork in traditional air conditioning systems are the reason behind over 30 percent of energy consumption during use, mainly if the ducts are located in a room that is not being cooled. 

Almost every ductless mini-split users find that they are saving on energy usage by keeping their Air Conditioner running consistently during the hot, humid days and nights of the summer months and turning the temperature up or down as needed.

  1. Cost-efficient

Every indoor air handling and distribution unit of your ductless mini-split system is controlled independently. It allows you to raise or lower room temperatures as you like by using a remote control.

Figuring Out The General Estimate Of Your Ductless Mini-Split Air Conditioner

The ideal way to figure out the size of your ductless mini-split air conditioner is by hiring a pro technician to help you out. However, you can figure it out by yourself. Here’s how you can figure out the general estimate of your ductless mini-split air conditioner:

 For example, if the room is 30 feet long by 40 feet wide, it would be 30 x 40 = 1,200 square feet. So to get the approximate BTU rating, the technician will multiply the room’s square footage by 25. So if you have 1,200 square feet and multiply that by 25, you get 30,000 BTUs.

Factors That Can Affect The Ductless Mini-Split Sizing

The environmental conditions and other external factors play a huge role in determining the proper size of the mini-split you need for your space. So, the best way to find the right size ductless is by knowing the factor that affects the ductless. 

Mini-split sizing. Here are Factors That Can Affect The Ductless Mini-Split Sizing:

  1. Climate

The Environment outside your house significantly impacts the temperature indoors. The size of your ductless mini-split air conditioner depends on whether you live in a hot or cool space. 

For instance, if you live in a cold place, your ductless air conditioner doesn’t need to work as hard, so you don’t need to purchase an air conditioner that’s too strong.

  1. Age of your house insulation

Believe it or not, the age of your house is a huge factor when it comes to how much it can affect the size of your ductless mini-split air conditioner. For example, suppose your house is old and has multiple holes.

In that case, you will need a more oversized ductless mini-split air conditioner as your ductless mini-split air conditioner has to work harder to keep the room at a proper temperature.

Also, if you live in an older home with poor insulation, it requires more power to cool or heat the space you are in, which means you will need a more oversized ductless mini-split air conditioner. 

  1. Height of ceiling

The height of your ceiling plays a massive role in picking the size of your ductless mini-split air conditioner. High ceilings affect the room size because they make the rooms larger. The standard ceiling height of most homes is around eight feet.

If your ceilings are higher than that, then it is recommended that you increase the BTU capacity of the mini-split you will purchase by at least 20 percent, the way you will get the perfect size ductless mini-split air conditioner.

  1. Sunlight

if your room faces the sun, that means it’s harder to cool your room, so that affects the size of the mini-split the room needs.

  1. Kitchen

If your room is next to the kitchen, the heart of the stove and the other electronic appliances make your room hotter than most rooms. So, this plays a massive role in the size of the ductless mini-split your room needs.

  1. Number of Occupants

People generate heat which can affect the size of the ductless mini-split you need. Therefore, you need to take note of the usual number of occupants in the room you are putting the ductless mini split air conditioner in.

  1. Doors and windows

The number of windows and doors in the room you place your ductless mini-split in affects the BTU load as these are not insulated. Therefore, the cracks and small gaps in your doors and windows can leak air, making the room lose the cool air quickly.

So, it’s essential to make sure the number of doors and windows are considered before buying a ductless mini-split air conditioner. 

You can find the right size ductless mini-split air conditioner for your house by keeping these factors in mind.
