When wildfire smoke settles into the foothills, the question is always the same: what do I do right now? We set up one home with a clear answer, and the equipment to run it.
When wildfire smoke settles into the foothills, the question is always the same: what do I do right now? Open the windows or seal the house? Run the system or shut it off? For a home in the Boise Foothills, we replaced that uncertainty with a routine.
The plan: seal, circulate, flush
The center of it is the outside-air damper. It now closes with a switch beside the furnace, so the house can shut out smoke when the air outside turns and reopen for fresh air once it clears. When smoke is in the valley, close the switch, seal the house, and circulate the air inside. When it passes, open back up and flush the house out. A simple routine the homeowner can run without second-guessing it.

Two layers, each doing one job
The home runs two filters that handle different problems. A MERV-13 stays in place for everyday particles, changed every month or two. A carbon filter carries smoke and odor through wildfire season, when that's what the air needs most. Two layers, kept simple, on a schedule the homeowner knows.

A clear read on the air inside
We added an Ecobee Premium with air-quality monitoring, commissioned to the homeowner's preferences. It gives a clear read on indoor air and sends an alert the moment something shifts, so the routine is driven by what's actually happening inside, not guesswork.

The diligence underneath the plan
A plan only holds if the equipment under it does. So before any of the above, a full pass: a few return-section leaks sealed with UL-181 tape, a loose furnace fitting tightened before it could leave the home without heat, a leaking condensate boot on the inducer repaired, and the condenser coil cleaned. Static pressure with the MERV-13 came back strong.

One honest note for later
On the cooling side, readings showed the system slightly low on charge. It runs fine, and there's no leak we could find at evaluation, so this isn't urgent. The recommendation is a recharge to bring the refrigerant back to spec, on the homeowner's timeline, whenever it's convenient.
The outcome: a routine, not a worry
Smoke season in the foothills is a yearly certainty. What changed here is the response to it: a clear routine, equipment set up to run it, and a read on the air to know it's working. Seal up when the air turns, flush when it clears, and handle the rest of the year with the system running clean.

The result
A routine, not a worry
The home now has a clear routine for smoke season: an outside-air damper that closes with a switch, a carbon filter backing up the MERV-13, and an Ecobee Premium reading indoor air quality in real time. Underneath it, return leaks sealed, a loose furnace fitting tightened, a condensate leak repaired, and the coil cleaned, with static pressure confirmed strong.
