Mini Split Air Conditioners & Heat Pumps(45 products)

Choose the Right Mini-Split Air Conditioner or Heat Pump

Mini-split systems are an efficient option for heating and cooling individual rooms or zones without the need for ductwork. Whether you need a ductless air conditioner for summer or a mini-split heat pump for year-round comfort, understanding the system components, ratings, and features will help you make an informed decision.

Understand the Components

A mini-split system includes two main parts:

• Air handler (indoor unit) — distributes heated or cooled air into the room
• Condenser (outdoor unit) — houses the compressor and circulates refrigerant

Mini-split air conditioners are designed for cooling only, while a mini-split heat pump can both heat and cool, offering more flexibility for year-round use.

Compare Energy Efficiency Ratings

When comparing mini-split systems, check these performance ratings:

• SEER (Seasonal Energy Efficiency Ratio) — cooling efficiency over a season
• EER (Energy Efficiency Ratio) — efficiency at a set outdoor temperature
• HSPF (Heating Seasonal Performance Factor) — heating efficiency across a season

Systems with higher SEER, EER, and HSPF ratings offer better energy savings and performance, especially in regions with extreme temperatures.

Select the Right Size and Voltage

Choosing the correct system size and voltage ensures optimal performance. Single-zone mini-split AC systems are suitable for small rooms, while multi-zone systems can connect multiple air handlers to a single condenser for larger homes. Make sure the voltage of the system matches your home’s electrical service for safe operation.

Look for Advanced Features

Many modern mini-split systems come equipped with inverter technology, which adjusts the compressor speed based on the heating or cooling demand. This improves energy efficiency, maintains a consistent indoor temperature, and reduces wear on the system compared to fixed-speed units, as well as reducing noise.

Plan for Proper Installation

Placement is key for effective operation:

• Install the air handler where it can distribute air evenly in the room
• Place the condenser outdoors in a well-ventilated area, away from obstructions
• Professional installation helps ensure correct setup and maximum system efficiency. Consider using our Installation Services to get your system installed for you.

FAQs

Q: What’s the difference between a mini-split air conditioner and a mini-split heat pump?

A: A mini-split air conditioner only cools, while a mini-split heat pump provides both heating and cooling.

Q: What are SEER, EER, and HSPF ratings, and why do they matter?

A: These ratings measure energy efficiency for cooling and heating. Higher numbers mean better performance and lower energy costs.

Q: What is a ductless heat pump?

A: A ductless heat pump, also known as a mini-split system, is a heating and cooling solution that doesn’t require traditional ductwork. Instead, it consists of an outdoor unit and one or more indoor units, connected by refrigerant lines.

Q: How does inverter technology benefit a mini-split system?

A: Inverter technology allows the compressor to adjust its speed, improving energy efficiency and maintaining more stable room temperatures.

Q: Can I use a mini-split system for multiple rooms?

A: Yes, a multi-zone mini-split system connects several air handlers to one outdoor unit, making it ideal for cooling or heating multiple spaces.

Q: What voltage do I need for my mini-split?

A: Check your home’s electrical system and product details to choose a mini-split with the correct voltage for safe installation.
