What is not part of ductwork 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, and NorTech flags it before you book. A full replacement of the ducts usually reaches that level.
- Replacing the furnace, air conditioner or heat pump itself. Those are separate HVAC services done by pros who hold the license.
- Cleaning the inside of ducts to remove dust. That is the air duct cleaning service.
- Mold remediation inside ducts or the house. If a pro finds mold, they stop and tell you, and it goes to a specialist.
- Adding insulation to the attic floor or crawl space itself, or sealing the building shell. Those have their own services.
- Gas line, flue or electrical work connected to the equipment. Those are licensed-trade work for the matching pro.
- 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 ductwork installation & repair
Duct work connects to heating and cooling equipment and affects airflow and combustion air, so in many places it is licensed-trade work. The pros who do it hold the license, and they can tell you whether your job needs one.
A new duct run, a major replacement or a change to the layout commonly needs a permit and an inspection, often before the ducts are covered. Small sealing and repair jobs may not. Your pro tells you which applies.
Look at the pro profile for their license and insurance. Ask to see the permit and the inspection record for new runs, and keep any test results from airflow or leakage checks.

Before you book ductwork installation & repair
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Note which rooms are the problem
Write down the rooms that are too hot or cold, which season, and what time of day. A pattern like an upstairs room in the afternoon points to a different fix than a basement room in winter.
Check the filter first
A clogged filter reduces airflow all through the house and mimics a duct problem. Replace it before the visit so the pro is measuring the real ducts.
Open all the registers
Leave the registers and return grilles open and unblocked by furniture or rugs. Closed registers can raise the pressure inside the ducts and increase leaks.
Photograph what you can reach
If you can safely look in the attic or crawl space, photograph ducts that look crushed, wet, disconnected or chewed. Do not walk on joists or insulation you cannot see.
Clear the access
Clear the path to the attic hatch, crawl space door and the air handler. Move stored items so the pro can see the full run.
Ask about a pressure or leakage test
A before-and-after reading of airflow or leakage shows whether the work helped. Ask each pro whether they include one and what they record.
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.

Best time to book ductwork installation & repair
Attics and crawl spaces are miserable and sometimes unsafe in peak summer heat. Spring and fall give the pro a workable space, and you finish the repairs before the heating or cooling season puts the system under load. In Palo Alto, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain.
Often booked together with ductwork installation & repair
Book several services with one pro. Pros set their own bundle discounts.
Cleaning removes dust and debris once the leaks and damage are fixed, so the cleaning lasts longer.
Insulating the attic or crawl space around the ducts keeps the whole system from losing heat or cold.
Ducts are often sealed or resized in the same project as a new furnace, air conditioner or heat pump.
An inspection can reveal airflow and condition problems and helps you decide between repair and replacement.
