A duct problem looks exactly like a system problem
The room that is always cold, the system that runs constantly, the upstairs that will not cool — those are duct complaints far more often than equipment complaints. Which is how people end up replacing a working furnace and keeping the problem. We measure the ducts before anybody talks about new equipment.
Static pressure is the number to ask about
Static pressure is how hard the blower is fighting to push air through the system. When it is high, the ducts are restricting it — too small, too long, crushed, or choked at the filter — and a blower fighting a restriction moves less air, runs hotter and fails sooner. Most companies never measure it, which is why undersized ductwork survives one equipment replacement after another.
Tape fails, and leaks pull in more than they lose
Cloth duct tape dries out and peels, usually in the crawlspace where nobody looks; mastic and foil tape stay stuck. Leaks matter twice over: on the supply side you lose conditioned air, and on the return side the system pulls crawlspace or attic air into the house, dust and damp included. Sealing fixes the comfort problem and the dust problem at the same time.
How A Visit Goes
- 01
We Come And Diagnose
A real diagnosis, not a glance at the age plate. You get told what has failed and why, in words that make sense.
- 02
Repair Is Quoted First
If it can be fixed economically, that is the quote you get. A replacement number only comes out when repair genuinely does not make sense, and we will show you the arithmetic.
- 03
Sizing By Calculation
For a replacement, we measure the house — insulation, windows, ducts, orientation — instead of copying the old unit's label. Oversized systems short-cycle, run humid and wear out early.
- 04
Installed And Commissioned
Charged to spec, airflow measured, ducts sealed and every register balanced. An install that is not commissioned is only half done.
- 05
You See The Numbers
Temperature split, static pressure, and the settings we left it on — written down, so the next person has a baseline.
Ductwork & Airflow: common questions
Is duct cleaning the same thing as duct sealing?
No. Cleaning removes dust from inside the ducts; sealing stops air escaping from them. Cleaning helps when there has been construction, a rodent problem or visible debris, and it does nothing for a cold room. Sealing and balancing are what change how the house feels.
One room is always cold. Do I need a bigger furnace?
Almost never. It is usually the run feeding that room — too long, too small, leaking into a crawlspace, or a register nobody has balanced since the house was built. A bigger system pushed through the same restriction gives you the same cold room.
Do you have to open up walls and ceilings?
Most of the time, no. Ducts in a crawlspace, attic or basement are reachable, and that is where the leaks and the crushed runs usually are. Where a run is buried in a finished wall we tell you that before we start and talk through the options.
Heating & cooling throughout east Multnomah County
Most of our work is in east Multnomah County and the neighborhoods around it. Two weeks a year everybody calls at once — the first hard frost and the first real heat — so if you already know your system is on its last season, booking outside those weeks gets you a better job and a shorter wait.
