The service
What mini-split installation & repair is, what a visit covers and where the line is.

What is not part of mini-split installation & repair
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Any job where labor and materials together reach $1,000 or more is done by a licensed contractor. A new mini-split system usually reaches that level, and NorTech flags it before you book.
- Refrigerant handling, evacuation and charging is licensed-trade work with a federal certification, done by pros who hold both.
- New circuits, a subpanel or a service upgrade to power the system: that is a licensed electrician when it goes beyond the equipment disconnect.
- Building ductwork for a ducted mini-split beyond what the unit needs. That is the ductwork installation and repair service.
- Cutting structural framing, cutting through masonry beyond a line set sleeve, and roof or exterior wall repair afterward.
- Replacing a whole-house furnace and central AC. That is the HVAC system replacement service.
- In Palo Alto, city of Palo Alto requires permits for structural and electrical work. NorTech's handyman scope stays under the exemption threshold.
License and permits for mini-split installation & repair
A mini-split is a sealed refrigerant system with its own electrical supply. Connecting and charging it is licensed-trade work, done by pros who hold the license and the federal refrigerant certification.
Installation commonly needs a permit, and some places also inspect the electrical connection and the outdoor unit placement. A repair on an existing system may not. Your pro arranges the permit and tells you what it covers.
Check the pro profile for their license, certification and insurance. Ask to see the permit and the startup readings when the job is done, and keep the model numbers and warranty paperwork.

Before you book mini-split installation & repair
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Choose the rooms and the goal
Decide which rooms need it and whether you want heating, cooling or both. Rooms that are mostly used at night may need different placement than a living area.
Photograph the walls and the outdoor spot
Take photos of the indoor wall where the unit would go, the outside wall behind it and the ground or wall where the outdoor unit would sit. This helps the pro plan the line set route.
Check your electrical panel
Look at the panel for open breaker spaces and note the size of the main breaker. A mini-split needs its own circuit, and the pro can tell you if the panel can carry it.
Measure the room
Write down the room dimensions, ceiling height and number and size of windows. A sunny west-facing room needs more cooling than a shaded one of the same size.
For an existing unit, clean the filter
Washable filters can clog and contribute to weak cooling and frozen coils. Rinse them as the manual says, let them dry and note any error code on the display before the visit.
Ask what the install includes
Ask each pro whether line set cover, pad, condensate pump, permit and startup checks are part of the price. The scope differs from pro to pro.
Say where in Palo Alto you are
Add your neighborhood, for example Old Palo Alto, Crescent Park, and Professorville, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.
