• Basement and garage installations
• Home additions and remodeling projects

JAM Plumbing can help coordinate the installation so the mechanical, electrical, and refrigerant portions of the project are completed by the appropriate qualified trades.

Professional Mini-Split Installation Matters

Proper installation is important for the performance, efficiency, and reliability of a ductless mini-split system.

JAM Plumbing focuses on proper equipment placement, secure mounting, clean line-set routing, condensate drain installation, and coordination of the different trades required to complete the system.

Electrical connections are completed by a qualified electrician, and refrigerant connections and charging are completed by an appropriately certified HVAC/refrigeration professional when required.

Planning the Right Ductless Mini-Split System for Your Home

Choosing the right ductless mini-split system involves more than simply selecting an indoor unit. The size and layout of the home, number of rooms or zones, location of the indoor units, outdoor condenser placement, line-set routing, condensate drainage, electrical requirements, and heating and cooling needs should all be considered before installation.

Single-Zone or Multi-Zone?

A single-zone mini-split is designed to heat and cool one specific area and can be a great option for bedrooms, home offices, garages, additions, or other individual spaces.

Multi-zone systems can connect multiple indoor units to one outdoor condenser, allowing different areas of the home to have individual temperature control.
