Choosing the Right Mini Split: A Buyer’s Guide to Ductless HVAC

Choosing the Right Mini Split: A Buyer’s Guide to Ductless HVAC

Are you considering adding a mini split HVAC system to your home? If so, you’re in good company. Mini splits or ductless HVAC systems are becoming increasingly popular because of their energy efficiency and flexibility. With so many different options on the market, however, it can be tough to choose the right one. In this buyer’s guide, we’ll help you understand what to look for in a mini split and how to choose the right one for your home.

Determine Your Needs

The first step in choosing the right mini split is to determine your needs. You’ll want to take into account the size of the room you’re installing it in, your climate, and your budget. Different systems are designed for different room sizes, so it’s important to choose one that can adequately cool or heat the space you’re installing it in. You’ll need about one ton of cooling capacity for every 500 square feet of living space. Also, consider your climate since units with higher HSPF or heating seasonal performance factor ratings are better equipped for colder climates.

Choose the Right Type

There are different types of mini splits on the market, and each has its own pros and cons. Wall-mounted units are the most common and are attached to a wall near the ceiling. Ceiling cassette units are mounted in the ceiling and are great for larger rooms and commercial spaces. Floor-mounted units, on the other hand, are installed on the floor and are ideal for low-profile rooms with limited wall space. There are also ducted mini splits that are installed in your ceiling or attic and a duct system for zoned cooling and heating. Depending on your specific needs, you may need more than one type.

Determine BTU

BTUs or British Thermal Units measure the amount of energy needed to raise or lower the temperature of one pound of water by one degree Fahrenheit. You’ll want to select a mini split unit with an appropriate BTU rating to ensure optimal efficiency. The Rating of an HVAC’s BTU ranges from 7,000 to 36,000, with a high rating, usually placed in larger rooms or open concept spaces.

Consider Efficiency and Cost

When shopping for a mini split, consider both energy efficiency and cost. Units with higher SEER ratings are more efficient and can save you money in the long run on your energy bill. However, the initial cost of a more efficient unit may be higher. Be sure to balance upfront costs and long-term savings when choosing a mini split.

Choose a Reputable HVAC Company

Finally, you’ll want to choose a reputable HVAC company to install your mini split. Not only will a reliable company help you choose the right system, but they’ll also install it correctly. Look for a company that is licensed, insured, and has years of experience installing mini splits. Don’t hesitate to ask for references or reviews beforehand.

Choosing the right mini split system for your home can seem overwhelming, but with careful research and consideration, you can make an informed decision that can improve your home’s comfort level and save you money on your heating and cooling costs. In this buyer’s guide, we’ll cover all the bases to help you choose the right ductless HVAC system for your needs.

Before you begin shopping for a mini split system, it’s important to understand the various components that make up the system. A typical mini split system consists of an outdoor condenser unit and an indoor air handler unit, which are connected by a conduit that houses the refrigerant tubing, electrical wiring, and drain lines. Additionally, some units may include multiple air handler units that can be installed in different rooms or zones throughout your home. Make sure you know the size and layout of your space before selecting a mini split system to ensure you choose the right number of air handlers and the proper system capacity.

Another critical factor to consider when selecting a mini split system is the unit’s energy efficiency rating. Look for units with a high Seasonal Energy Efficiency Ratio (SEER) and Heating Season Performance Factor (HSPF) rating. These ratings are used to measure the unit’s cooling and heating efficiency. The higher the rating, the more efficient the unit will be. Since mini split systems run continuously, you’ll want to make sure you choose a unit that is energy-efficient to keep your energy bills under control.

When it comes to selecting the right mini split system for your home, you’ll want to consider the features that matter most to you. Some mini split units come with Wi-Fi connectivity, remote control, or programmable thermostats to make it easier to regulate the temperature in your home. Others may feature additional air purification or dehumidification capabilities to improve indoor air quality.  Make sure you understand the features available to you and choose those that best meet your needs.

Another important factor is installation. Many mini split systems require professional installation due to the complex wiring and refrigerant lines needed to connect the outdoor and indoor units. Be sure to factor in the cost of installation when considering a mini split system. Professional installation can also ensure that your system operates at maximum efficiency and helps to extend the system’s lifespan.

Finally, it’s important to read and understand the manufacturer’s warranty before making a purchase. A typical mini split system comes with a five-year warranty, but the length and coverage of the warranty may vary depending on the manufacturer. You’ll want to make sure you understand what is covered and what is not covered before making your purchase. Additionally, consider purchasing a unit with an extended warranty for added peace of mind.


When it comes to choosing the right mini split for your home, the key is to assess your needs, choose the right type, determine the appropriate BTUs, consider the efficiency and cost, and choose a reputable HVAC company. We hope this buyer’s guide has been helpful in simplifying the process and making it easier to choose the right mini split HVAC system for your home. Make sure to ask questions, and work with a reliable and experienced HVAC company to get the most out of your mini split.

Choosing the right mini split system for your home involves careful consideration of system capacity, energy efficiency, features, installation, and warranty. By taking the time to research and understand these factors, you can make an informed decision that can improve your home’s comfort level, indoor air quality, and energy efficiency. Keep these factors in mind as you explore the various options available to you and make the right choice for your home.
