Klima vs Ecobee: The Best Smart Thermostat for Ductless Mini-Splits in 2025

As more homeowners embrace energy-efficient heating and cooling, ductless mini-splits have surged in popularity. In 2024, the global mini-split market was valued at USD $16.55 billion, and experts predict it will double to $33.63 billion by 2033 — an impressive 8.2% CAGR.

In the U.S., single-zone mini-splits dominate the residential sector, especially in homes without existing ductwork. With this rise, many homeowners are asking: Which smart thermostat works best with ductless A/C systems?

Popular options like Ecobee smart thermostats revolutionized home climate control for ducted HVAC systems, but it struggles with ductless mini-splits unless you add adapters or complex wiring. 

Below, we compare Ecobee vs Klima so you can choose the best smart thermostat for your home.

What Is the Ecobee Thermostat?

The Ecobee Smart Thermostat rivals Nest in popularity. It supports Alexa, Apple HomeKit, Google Assistant, and other smart home devices, offering broad smart-home integration.

But like Nest, Ecobee is designed for ducted HVAC systems, not ductless mini-splits.

To use it with a mini-split, you need a third-party adapter or interface module — often installed by a professional. This adds cost and limits functionality since mini-split systems use brand-specific control protocols.

Pros

• Excellent multi-platform integration
• Has basic physical controls
• Detailed energy analytics
  

Cons

• Not designed for mini-splits
• Requires wiring and often professional installation
