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.

Duct location and access
Ducts in a hot attic, crawl space or wall cavity are harder to reach than those in a basement.
Size and layout of the system
A large house with several zones and long runs has more joints to find and seal than a small single-floor home.
Duct material and condition
Metal trunks, flex duct and duct board each leak in different places.
Return-air design
Returns that use wall or floor cavities can pull attic or crawl space air into the system and leak heavily.
Test method and target
Pros use different pressure tests and reporting.
Where in Woodside the job is
Woodside's properties span everything from 1920s craftsman estates to modern architectural showcases. Providers are experienced with historic materials, cedar siding, stone masonry, and the particular demands of hillside properties. Tell the pro your neighborhood or ZIP code so they know the age and style of the home.

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.

  • Replacing the furnace, air conditioner or heat pump, and any refrigerant work: those are licensed HVAC services.

  • Air duct cleaning. That has its own service.

  • Electrical work on the air handler or thermostat wiring.
  • In Woodside, town of Woodside historic properties may require permits even for minor repairs. NorTech confirms scope before work begins.

Plan your visit

How booking works, how to get ready, and what to expect where you live.

How booking duct sealing & leak testing works

  1. Say what needs doing

    Add your ZIP and a few words about the job.

  2. Compare pros near you

    Each pro sets their own price and warranty. NorTech does not pick for you.

  3. Book the pro you pick

    Add photos and details on their page. Your card is held and only charged after the work and the photos.

  4. Photos and a warranty

    Your pro backs the work with a workmanship warranty — if covered work is not right, your pro makes it right, free.

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.

0/7
Let’s get you readyTap a card when you have done it.

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 Woodside you are

Add your neighborhood, for example Central Woodside, Woodside Heights, and Skywood, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.

How where you live changes duct sealing & leak testing

Add your ZIP in the booking card at the top to see weather alerts and the season for your area.

Where your ducts sit decides how much they waste

Ducts in a hot attic or vented crawlspace lose the most energy, because leaks push conditioned air outside and pull unconditioned air in. Ducts in a basement or inside the insulated envelope waste far less. Tight attics, low crawlspaces and buried runs take longer to reach and seal. Your pro needs to know where the ducts run and how safely they can be reached.

Fill in the blanks first. The note goes to the pro you choose.

Often booked together with duct sealing & leak testing

Book several services with one pro. Pros set their own bundle discounts.

Ductwork Installation & Repair

Runs that are crushed, undersized or missing go beyond sealing and need duct repair or replacement.

Insulation (Attic/Crawlspace)

Insulating the attic or crawlspace pairs with tight ducts to keep conditioned air where you want it.

HVAC Maintenance & Tune-Up

A tune-up checks the equipment that the ducts serve, including filters and airflow.
