We answer within a few working days. Privacy requests under the GDPR or the CCPA are answered within thirty days, as those regulations require.
Corrections and measurements
If a record does not match what you measure, send the room, its floor area, how the air moves through it, the carrier you used and the number of units. Measured set-ups are what this register is built from, and a correction is published on the record it belongs to.
Rooms we do not cover yet
The register covers eight rooms. Basements, utility rooms, stairwells and campervans are all reasonable candidates and are not in it. If you have measured one of them, describe it — the ones that repeat get written.
What we do not do
We do not accept sponsored placements, paid links, guest posts or product placement in the register. We do not review a carrier in exchange for a sample. Mail offering any of these is answered with a decline.
