|An integral part of our designing the Air Flow System
for your home or business is the process of determining the necessary duct
sizes and shapes (round or rectangular) and distribution lengths of the metal
duct work to properly supply and exhaust air for your environmental comfort
It is often common for a new home owner to have an expensive and normally energy
efficient heating or cooling device installed in their home only to have its
benefits negated by poorly designed and installed ductwork. The reduction in
efficiency and increase in operating cost can occur several ways:
-- Many 90 degree turns with no 'hollow-core' turning vanes to direct flow
-- Unsealed joints and connections that allow heated/cooled air to escape into
-- Build up of dust that restricts flow and causes hideouts for bacteria and
-- Excessive noise due to air striking flat surfaces and changing direction

"Achieving a comfortable, energy-efficient home requires a different
approach to the traditional home-building process: a whole building approach.
This perspective views the house as an integrated system with each component
working together to achieve greater energy efficiency and comfort.."
* Reduce your energy consumption 25-40%.
* Cut your utility bill $160-320 per year.
* Improve your home air quality.
* Reduce safety concerns from pressure imbalances.
At Andrews Mechanical, Inc. we take the appropriate steps to
determine the necessary ducting requirements of the project (residential, commercial,
industrial). We then build the ducting
in our modern, fully equipped sheet metal fabrication shop.
We have a complete selection of round and custom rectangular duct, fittings,
transitions, reduced friction take-offs, expansion joints and associated parts.
The proper design and use of correct components (duct size, fan size, etc)
will save the homeowner money.
