A large ductless system with a BTU of 36,000 can effectively cool a room up to 1,500 total square feet, while smaller units usually start at around 9,000 BTU and can cool approximately 350 square feet of space (the size of approximately 2-3 bedrooms). One of the most installed sizes is a 12,000 BTU mini-split. This will heat and cool approximately 450 to 550 square feet, or about the size of a studio apartment. Minisplit coverage starts at approximately 300 square feet for a single-zone system designed for a small room such as a bedroom.
6,000 BTU to 8,000 BTU units are ideal for use in a small room, such as a bedroom or office. Larger mini split heat pump systems are ideal for 2,500 to 3,000 square feet. Shipments to Canada may incur duties, taxes and brokerage fees after your order is confirmed. These fees are non-refundable and will not be reflected in your order total.
Each ductless indoor unit provides a set number of BTUs of cooling power. For single-zone units, you just need to know the number of BTUs associated with the indoor unit and make sure it fits the square footage you are cooling. For multi-zone systems, both outdoor and indoor units have an associated BTU rating. An advantage of a ductless split system is that each indoor unit works independently.
Please note that if you are buying a multi-zone system, you must look at the BTU rating for each unit (or zone). For example, an AC can use 30,000 BTUs in total, each indoor unit uses 9,000 BTU, and the outdoor unit uses 12,000 BTU. FAQ about mini split air conditioners How do I choose a mini split air conditioner without ducts? Like all air conditioners, you need to know how many BTUs you need to cool or heat the area where you want to install your mini split. You should also consider the number of air handles you will need for your application.
Normally what you would need is one air handler per room, but if your house has open areas, you may be able to cool multiple rooms with just one multi-zone outdoor unit. There are many options for the types of ventilation grilles or manipulators that you can buy. Some sit in the house and are mounted on the walls, and others can be mounted on the ceiling. It is important to talk to a certified air conditioner about your options to help you decide which one meets your needs.
What are the pros and cons of a mini split air conditioner without ducts? Ductless mini split air conditioners are a cost-effective option instead of central air conditioning. They are usually more expensive than wall or window air conditioners and you will need an HVAC professional to install the unit. As the compressor is located outside, mini split air conditioners are very quiet and efficient. Mini air conditioning units can also help keep your home safer, as there is only a small hole in the wall.
Mini-divisions can include multiple modes to keep your home full of fresh and fresh air in summer and warm air in winter. Ductless units are also known for their quiet operation, especially compared to their large, clumsy air conditioner or heater. Whether you already own a ductless system and are looking for help with tuning, maintenance and repair, or considering ductless systems, Superior Mechanical Services can help. The amount of hot and cold air your home can keep trapped inside will need to be considered, as this insulation plays an important role in the overall performance of your ductless system.
