Quilt Launches 3-zone Ductless Heat Pump for Residential Applications
U.S. startup Quilt launched a new three-zone ductless heat pump for residential applications. The system allows for independent temperature control in three separate areas using just one outdoor unit. It utilizes R32 (difluoromethane) refrigerant and boasts a Coefficient of Performance (COP) of 4.2 at 8°C.
Aesthetic Integration
The slim indoor units feature customisable covers that can be painted, wallpapered, or finished with white oak veneer to match home decor. A three-zone heat pump uses one outdoor unit to power three indoor units, letting you set different temperatures for three separate rooms. This setup provides personalized comfort and efficiency by only heating or cooling the spaces you're using. According to producers, the system is the most effective three-zone ductless heat pump currently available. Additional features include room-by-room control via the
Quilt Dial and mobile app, millimeter-wave occupancy sensing, and over-the-air software updates, among others.
According to Towards Chem&Materials, the ductless HVAC systems market size accounted for USD 87.55 billion in 2025 and is predicted to increase from USD 94.26 billion in 2026 to approximately USD 183.15 billion by 2035, expanding at a CAGR of 7.66% from 2026 to 2035 as demand for sustainable, energy-efficient, and zone-controlled climate alternatives is increasing in commercial and residential sectors.
In May 2024, Quilt debuted its first smart heat pump, following a successful $33 million Series A funding round earlier that year. The investment was co-led by Energy Impact Partners and Galvanize Climate Solutions, with additional backing from Lower carbon Capital, Gradient Ventures, and several others, including TV personality Drew Scott.
Energy Efficiency and Sustainability Accelerate the Ductless HVAC Systems Market
- Consumers are increasingly shifting towards systems that offer higher efficiency over conventional ducted units, using inverter technology to minimize power consumption.
- Ductless systems are the first choice for renovating spaces and r retrofitting older buildings, as they cut the need for costly installation.
The integration of sensors and smart thermostats enables enhanced, automated temperature control, fuelling the adoption in commercial buildings and smart homes. - Governments are pushing for low-emission, cleaner technologies through stringent energy building codes and the phasing out of high-GWP refrigerants.
