Whenever your system runs, your air cycles through ducts in a hot, dusty attic. If attic air is getting into that loop, no filter in the house can keep up. We find where it gets in and fix it there.
Concern 6 of 7
Many homes unintentionally pull air from the attic, the garage or outdoors through leaking ducts and open gaps, bringing dust, insulation particles and pollutants into every room. A better filter can’t catch air that enters after it. We find where it gets in and fix it there.
Free Duct & Attic Assessment, about 2 hours, with you present. We do not sell or service HVAC equipment.
Follow the Air
Your system pulls air out of your rooms, runs it through a filter and the air handler, and pushes it back out through the ducts. The return side pulls. The supply side pushes. Wherever that loop has a gap, it pulls attic air in on the way back or pushes your cooled air into the attic on the way out. Select a stop, or a number on the house, to see what can happen there.
Stop 1 of 5
Every time the system runs, it pulls air out of your rooms and sends it back to be cooled. That air should be the only thing the system breathes in.
Stop 2 of 5
The return duct is under suction. A gap, tear or loose connection here doesn’t leak air out. It pulls hot, dusty attic air in, along with insulation fibers.
Stop 3 of 5
A filter only cleans the air that passes through it. Air that slips in past the filter, or around a loose grille, goes straight to the blower.
Stop 4 of 5
The supply side is under pressure. Gaps, tears and slipped connections here push the air you paid to cool into the attic before it ever reaches a vent.
Stop 5 of 5
Whatever the air picked up on the way is delivered to every vent the system serves. Gaps at the wall tops and ceiling openings let attic air seep in directly, even when the system is off.
The assessment finds which of these your home actually has: leakage split by supply and return, room pressures, thermal images and air quality readings, all photographed.
Three Ways It Shows Up
Source control first. Then filtration, treatment and fresh air, only if the readings call for them. Not every home needs every step.
1 Dust that comes back
Behind the filter, nothing is filtered. A return-side gap no wider than a pencil, under blower suction for hours a day, feeds attic air to every room.
Signs
What we look at
Every opening between the attic and the loop, the return side first: leaks behind the filter, ducts with failed jackets or torn liners, supply ducts pulled off their vent boxes, and a grille or filter can that lets air slip around the filter. Leakage is tested, split by supply and return.
What usually goes in
2 Allergies and stale air
Clean the air you have, after you stop re-contaminating it. Each step only works on the air that reaches it.
Signs
What we look at
Filter and grille sizing against the system, so a deeper filter doesn’t starve it; room pressure, because exhaust-only fans and closed doors pull air in through gaps; and air quality readings taken before and again after the loop is closed.
What usually goes in, once the loop is closed
You will not be sold a filter, a purifier or a ventilation system to fight a leak that costs less to seal. If your home needs only source control and the right filter, that is what we’ll say.
3 Attic air getting in
The dirtiest air in the house is right above the ceiling, and the top of every interior wall is open to it.
Signs
What we look at
The wall tops and every ceiling opening with the thermal camera from inside the house, where attic air shows up as a warm streak; the attic hatch; the garage’s shared wall, ceiling and hatch; and which rooms pull hardest, measured with the doors closed.
What usually goes in
The Order We Work In
It is tempting to start with a better filter or an air purifier. But a filter can’t clean air that never passes through it, and a purifier has to work against every gap still letting attic air in. That is why we correct indoor air quality in this order. Select each step to see what it changes.
Illustrative, not to scale
As Found
Gaps in the return duct sit under suction and pull attic dust into the loop after the filter. A standard filter catches some of what comes from your rooms, and none of what comes from the attic.
Step 1 · Source Control
Sealing the ducts and the attic stops contaminated air at the source, so the system only breathes the air from your rooms. Every other step depends on this one.
Step 2 · Filtration
With the leaks sealed, all of the air passes through the filter, so Deep Pleat Filtration can finally do its job on the everyday dust circulating through your home.
Step 3 · Treatment
PuriFi air purification works on the finer particles still in the air of your home, once there is no longer a steady supply coming in from the attic.
Step 4 · Dilution
Last, Fresh Air Ventilation brings outdoor air in through a filter, so stale indoor air is diluted instead of simply recirculated. Only if the readings after the loop is closed call for it.
The services behind each stepEach step only works on the air the step before it left behind. A filter can’t clean air that enters after it, and fresh air can’t dilute a leak that never stops. Not every home needs every step.
Backed By
Every air-quality plan starts with source control, chosen from the readings the assessment takes. Which guarantees go into your package is decided with you.
See the difference
PuriFi air purification comes with particle monitors, so you can see the difference in your air for yourself.
Energy Savings Guarantee
“Your system uses less energy after our improvements, by the amount you choose.”
Sealing the loop is sized from the leakage test; typical results run 80 to 90 percent lower.
