Disadvantages of Mini Split Systems
Let’s have a detailed explanation of the disadvantages of the mini split systems in order to understand the reason behind these disadvantages.
The Installation Cost Is High
Are mini splits good for heating? Well, they are good but a person with a lower income can not afford to install a mini-split system because of their high installation cost. For example, a $1,500 mini split will cost you around $1,500 to install by a professional depending on the location. To reduce the mini split installation cost, many people are choosing to install their mini-split systems by themselves nowadays. Hence, the high installation cost may not be even considered a disadvantage.
Criticality of Placement
The houses designed for a central air system do not have a fixed location for the mini split head unit. On top of that, the mini split head unit must be installed at specific locations in order for the system to perform at the most optimal level.
Limited Air Quality Control
You can control the air temperature in the individual room but the quality of air control is limited. Mini split, especially ductless air conditioner systems generally do not have high-performance filters. Most of the time, they are meant to capture dust to prevent the cooling coil from choking up.
One of the most irritating disadvantages of the best mini split systems is the aesthetic concerns. Many houses are not designed for a mini-split system but for a central air system. Therefore, mini-split components such as refrigerator lines, drain lines, and wires are not concealed. And replacing a central air system with a mini-split system will result in having the mini-split lines running exposed on the surface of the wall both inside and outside the house.
How many mini splits do I need? Well, for a 1,500 sq ft sized house you would need three 12,000 BTY mini splits. A typical 1800 sq ft single-family house may use a 3-ton central air system for cooling. For the same-sized house, it often translates to 4 to 5 units of mini splits.
Difficult To Choose The Required Size
It is very confusing to select the correct size of the mini-split system for your house. Installing a system that is too big will mean that it cools the room too quickly and turns off prematurely. When this happens, you min-split cannot get all the humidity out of the room, and it will be uncomfortable.
The heating Level Is Not Uniform
The mini-split systems are designed to offer different temperatures in different rooms. But, believe it or not, all the rooms are not uniform. In one room you may feel cold and warm in the other room, at the same time. On extremely hot or cold days, your mini-split will struggle to keep up and won’t provide the same level of comfort that a traditional HVAC system.
Not Meant For Complete House
You may or may not accept but it is a fact that a mini-split system is not meant for the whole house. They run into problems when you try to heat or cool several rooms at the same time with a mini-split system. Remember, there is not any ductwork involved, so the air coming out of the mini-split will only travel as far as the mini-split can push it.
Costly Maintenance And Repair
If you are going to install the mini splits system, then be ready to spend more on the repair and pertinence of it. The professional will check and clean the filters, coils, and units themselves and ensure no refrigerant leaks. Your cost will be $150 to $300 per session, plus repair costs.
The Drainage System
The drainage system is a frequent subject of discouragement for the mini-split heat pump. As with all heating and cooling systems, small air conditioners also produce heat by cooling the hot summer air in your home. This condensate can collect inside the room and pass through pipes outside your home.
