The service
What duct sealing & leak testing is, what a visit covers and where the line is.
The short answer
Duct sealing and leak testing finds air escaping from your heating and cooling ducts and closes it. Duct Sealing & Leak Testing in Emeryville is booked through pros who cover its 1 ZIP codes, in neighborhoods such as Park Avenue District, Watergate, and The Triangle. In Emeryville, 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. NorTech lists pros who each set their own price and warranty, and the choice is yours.

What shapes a duct sealing & leak testing job
These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.
What you receive
A duct test is a diagnostic service, so the main product is information you can act on. Each pro sets what they provide, and a typical visit produces the following.
- Duct leakage readings taken before the sealing work
- A list of the leaks found and where they were in the system
- A description of the sealing and repairs completed
- Leakage readings taken again after the work
- Photos of problem areas and the repairs where taken
- Notes on insulation, sagging runs or equipment problems outside the visit
What is not part of duct sealing & leak testing
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. Larger duct scopes are handed to a licensed contractor, with the limit shown before you book.
- Replacing the furnace, air conditioner or heat pump, and any refrigerant work: those are licensed HVAC services.
- Full duct replacement or new duct design. That is duct installation work.
- Air duct cleaning. That has its own service.
- Attic or crawlspace insulation upgrades, air sealing of the house and asbestos or mold abatement.
- Electrical work on the air handler or thermostat wiring.

Before you book duct sealing & leak testing
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Note which rooms are uncomfortable
List the rooms that run hot, cold or stuffy, and whether it is worse in summer or winter. Rooms at the end of a long duct or over a garage are common trouble spots.
Look at your registers
Weak airflow, whistling, dust streaks around a register or gaps between the register and ceiling or floor hint at leaks. Photograph what you see and mention it.
Clear attic and crawlspace access
Clear a path to the hatch and the equipment, and tell the pro about low clearance, pests or stored items. Sealing means working along every run, so open access saves time.
Change the filter first
A clogged filter restricts airflow and can mimic duct trouble. Put in a clean one before the visit so the test shows the ducts and not the filter.
Have equipment details ready
Note the age and make of the furnace or air conditioner and any recent service. If you have an energy audit or earlier test results, share them so the pro can compare readings.
Ask which test and target they use
Pros use different testing methods and goals. Ask which one, what number they aim for and whether you receive the before and after readings in writing.
Say where in Emeryville you are
Add your neighborhood, for example Park Avenue District, Watergate, and The Triangle, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.
