Re: HVAC Balancing Valve Follow-Up Study

As part of the recent rebalancing of the closed loop (air conditioning and heating) system by Annandale Balancing an analysis of the noise levels in different tiers and on different levels of the building was authorized.

Simply put, in addition to providing for a proper water flow as determined by energy loads calculated by the association’s engineer, one of the objectives of the rebalancing was to assure that noise levels associated with water flow were at the lowest level possible.

In order to accomplish this, Lauren maintenance will be conducting an aural examination of your unit on WEDNESDAY, DECEMBER 1, 2004. This will be a very simple and short duration test. It does not involve any invasive activities within your home. It merely involves his entering your unit, listening and making notes upon what he hears.

Said information will be transmitted to The Lauren’s engineer, who will coordinate with Annandale Balancing as to any additional modifications that may have to be made in the balancing set-up, as it currently exists.

Thank you for your assistance and cooperation in this matter!
