About Duct Installation

Duct installation requires the placement of ductwork under floors, behind walls, and inside attics. Ductwork winds throughout a home directing air flow to registers and vents, distributing temperature controlled air. The entire duct system originates and ends in an air handling unit, usually located at or near the source of the conditioned hot or cool air.
We perform complete duct work for residential and commercial applications. No job is too big or too small whether you are building a custom home or carrying out a small reno project our team of experienced duct work specialist are ready to get the job done the right way for you.

Duct Replacement

How do you know when your duct work needs to be replaced? Most families won't at first, but if you.re paying attention, you can catch them much earlier and cut down on the total cost of the process. It also allows you time to have someone check your home heating and cooling system and make sure nothing is wrong with the furnace or air conditioner. Many times, symptoms in the ductwork and your comfort system will overlap; proper inspection will determine which you should be concerned about.
The most common ductwork problem is uneven home heating and cooling. Because ductwork carries the heated or cooled air to every corner of your home, a lack of comfort in one room or floor is usually a sign that the ductwork is having a problem in that part of the house. For example, if your second floor is much warmer than your bottom floor in the summer, the ducts may not be getting enough cooled air upstairs.
If you notice that your home comfort system isn't working as it once did, with generally lower efficiency and higher energy bills, it may be a ductwork problem. A gap between ducts can leak conditioned air out of the system while loss of efficiency in general can be a result of issues with either your ductwork or your comfort system or both.
When air quality becomes a consistent issue, your ductwork should be inspected immediately. Many times, this is a sign that you need cleaning. But, in some cases an increase in exhaust fumes or excess dust is due to a problem in the ducts that cannot be cleaned away.

Duct Insulation

insulating your ducts is the best way to make sure you're always getting the most out of your heating and AC system. In fact, you'll likely be pleasantly surprised at how your monthly energy bills go down once you have a proper insulation in place around your ducts.

Why it is important to properly design and install high quality, efficient ducted air systems ?

-- The efficiency of air distribution systems has been found to be 60-75% or less in many houses because of insufficient and /or poorly installed duct insulation and leaks in the duct system. -- Moreover, efficient duct system installations can reduce equipment size, further saving money for new or replacement equipment".

Understanding Basic Residential Ductwork Design

Radiant in-floor heating delivers heat directly from your floors. This is achieved through a series of hoses installed directly within the concrete. A boiler is hooked up to these hoses to supply warm liquid throughout the grid. This offers an The purpose of Residential Ductwork Design is to properly distribute the airflow, produced by your heating/cooling system, to your house. This involves Return Air (unconditioned) coming into the heating/cooling system. Then, by heating/cooling that air, delivering the newly conditioned air to your home. An improperly designed ductwork systems can cost money through inefficiencies, and in some cases, cause premature failure of heating and cooling equipment. This means that your home's ductwork system is just as important as the equipment used to heat and cool your home.

Most Important Things to Understand About Residential Ductwork Designs

Furnaces and air conditioners require a certain amount of airflow, measured in CFM (Cubic Feet Per Minute), to be passed through the equipment (supply and return ducts) in order for the equipment to function properly and efficiently.

All homes have unique requirements and construction that pose obstacles when designing the ductwork system to accommodate each room with proper airflow. (This is especially true with older homes.)

The Ideal Ductwork System achieves both goals by providing enough airflow to and from the heating/cooling equipment as well as the home. For maximum efficiency, this "ideal" system should also be sealed at all seams with aluminum tape, and should be properly insulated when exposed to unconditioned environments (i.e. crawl spaces and attics).

The most common design:

The most common design (Trunk Line Layout) is provided in the illustration below. This type of system incorporates the use of a "Trunk Line" or series of Rectangular Ducts that act as a main supply channel throughout the house. From these "Trunk Lines" come branch ducts (usually round) that extend, in various ways, to the registers which are strategically placed throughout the home.

Basic Guidelines for Ductwork Fittings and Placement

Supplies are located on outside walls.

Returns are located on inside walls. They should not be located in the same area as the furnace, nor should they be located by moisture sources such as kitchens or bathrooms.

Return Air CFM must be equal or greater than Supply Air CFM.

Wyes commonly reduce.

Tees split, but do not reduce, and an appropriate reducer must be added.

Dampers on take-off duct runs allow for adjustments of air distribution.

In order to maintain velocity, reduce duct size.

Never locate ducts at the end of the trunk line run. Last take-off run to be located 12" - 18" from end.

Always stagger take-off ducts by 12" to maintain pressure.

Use insulated duct or duct board in unheated spaces.

Flexible duct work must be stretched tightly for maximum air flow.

Example:

System is designed to move 3 Ton of A/C or 1200 CFM.

Overview

MA Duct Work Inc. specializes in commercial building duct installation. We employs our years of experience in duct installation to bring the best products and services to all of our commercial customers.
There are many things that make commercial duct installation different than residential work and they center on the building use and its size. For example, industrial machinery used for cutting, grinding, and sawing creates a lot of particulates in the air, which could be extremely harmful to building occupants. A simple duct system like that found in a home would never be sufficient to keep the air clean and conditioned. Our system designers and installers consider things like this when putting together the optimal commercial duct system in any building.

Duct Sizing

There is no "one size fits all" logic to designing commercial duct systems. You can't simply increase its size based on the square footage of a building. There is a lot of thought and planning that must go into the process. On the other hand, it is dangerous to assume that a small duct system in a commercial building will be sufficient. In this case you're likely to wind up with an overworked system that is prone to breakdowns. Our commercial ductwork specialists consider all of the factors in system design before making recommendations to our customers.

Importent Factors in designing commercial duct systems

There are many factors to consider when designing commercial duct systems. Answers to the following questions can be particularly helpful when customizing a system for each unique application:
Do you have an existing duct system?
Are you satisfied with its energy efficiency?
Are your energy bills reasonable?
Are there "hot spots" and "cold spots" in your building where temperature control is almost impossible?
Is your heating and cooling system running more than it should?
