Professional Heat Pump Installation Services for Your Home
Air-Source Heat Pump Installation
At 669 Heat, we expertly install air-source heat pumps that efficiently draw heat from the outdoor air even in chilly Sudbury winters. These systems deliver dependable heating and cooling, offering a year-round solution. Our certified installers carefully select outdoor unit locations, charge refrigerants correctly, and connect ductwork with precision to ensure top performance.
Ductless Mini-Split Heat Pump Installation
For homes without ductwork or zoned climate control, our ductless mini-split solutions offer a flexible and quiet alternative. We install indoor air handlers in the right locations for airflow and aesthetics, with precise line-set routing and secure mounting. Every system is tested for balanced, whisper-quiet performance.
Hybrid Heat Pump Installation
Combining the benefits of two systems, our hybrid heat pump installations integrate a heat pump with a backup heating system for ultimate flexibility. The dual-fuel setup automatically switches between heating sources depending on temperature and energy costs. 669 Heat’s installers fine-tune the system controls to deliver maximum efficiency in Sudbury’s changing seasons.
