When it comes to heating and cooling your home, central air conditioners and furnaces aren’t the only two options. Ductless heating and cooling systems, also referred to as mini-split systems, offer superior performance with a smaller footprint. These HVAC systems come with a wall-mounted indoor unit and an outdoor unit consisting of a compressor.

Mini-splits are ideal for cooling or heating small spaces such as condos and home additions like attics, garages and finished basements. However, a multi-zone system consisting of 2-6 indoor units can quickly cool or heat multiple rooms in your home using a single compressor.

If you’re looking to replace your old and inefficient HVAC system with a new one, consult this guide to learn how to pick a perfect ductless heating and cooling system for your home and discover the best ductless brands. We also recommend speaking with local HVAC professional in your area to get further advice on sizing and installation.

What makes the best Ductless Heating and Cooling Systems?

With endless options available in the market, choosing the right ductless system that meets your budget and performance requirements can be a challenge. This section explains the factors that you should consider when comparing brands that offer mini-split heating and cooling systems.


The price of a ductless system is the factor you’re likely to consider first. Most split systems cost $800-$6,000, offering different levels of energy-efficiency and features. An energy-efficient model costs more but ultimately provides monthly savings on energy bills. Also, many mini-splits qualify homeowners for tax credits or utility rebates, providing additional savings.

Energy-efficiency and performance

Not all ductless systems ensure the same level of performance and energy-efficiency. These systems come in different capacities to cool or heat rooms of various sizes. Make sure to calculate the actual BTUs (British Thermal Units) needed to keep your room cold or warm.Installing a large system wastes energy, while a less powerful unit must work continuously to maintain temperatures, leading to higher energy bills. As such, unit size matters when selecting a ductless system. Most brands display each unit’s cooling/heating capacity along with its size.

Each system has its own SEER (Seasonal Energy-Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings. The higher these ratings, the more energy-efficient the system will be. When buying a ductless system for your home, you should also look for units that are ENERGY STAR certified. This label ensures that the system offers energy savings without compromising performance and comfort.

Compressor Type

The type of compressor that a ductless heating and cooling system uses also influences total energy savings. A split system makes use of either a rotary or variable-speed compressor. A rotary compressor turns on and off to maintain required temperatures, operating either at full or no power. On the other hand, variable-speed compressors, also known as inverter compressors, run at different speeds to maintain optimum temperatures inside the room. Variable-speed compressors help you save on energy bills while ensuring total comfort all year round.

Additional features

Apart from basic cooling and heating functions, you might also want to consider advanced features in your split system. Advanced features include adjustable airflow, Wi-Fi-enabled remote monitoring and control, humidity control and programmable timers.

Customer reviews

Most reputed brands list customer testimonials on their website. These reviews are a great way to verify the claims made by the company about its products. Specifically, look for reviews on installation, performance and customer support to get clarity before you invest in a ductless heating and cooling system.


Most well-known brands offer warranties ranging from 5-12 years on their split systems. Choosing a model with a better warranty period will ensure that you get reliable performance out of your heating and cooling system without worrying about part replacement costs.
