Kitchen Remodeling Edition

When it comes to the ductwork, kitchen remodeling requires resolving some of the most important issues, which could arise during the remodeling process.
For example:

Bathbox installation/relocation
High wall heat installation
Toe kick heat installation

If in your kitchen you are doing a remodeling project on moving a wall, you may find out that existing heat no longer can serve your kitchen area and should be moved to another location. It is why I give you three options of resolving this issue:

If you have an unoccupied span of wall you can install a bath box in, if not, you can install a bath box high above your wall cabinets, or you can set it low and bring such necessary heat to your kitchen area as the Toe Kick heat.
Next and the most important part of your kitchen-remodeling project is a kitchen exhaust. Here you can also have three options:

Microwave Hood exhaust
Kitchen Hood exhaust
Downdraft Range exhaust

All three of them require resolving of some ductwork installation issues and you are able to find the solutions in my book.

The “Jumper Installation” chapter of my book gives you insight on how to run heat or exhaust if you unable to run it as a “straight shot”.

All the chapters are very cheap and the book price is even cheaper than combine the price of all chapters. However, you may be worried that there is no answer to your particular question or issue, and then you have two options:

Energy     Saving      Edition

On the web, you'll stumble upon countless websites advocating the importance of energy conservation. They often furnish a generic list of measures you can adopt in your home to align with their recommendations.

What sets my website apart? Unlike others that regurgitate the same old energy-saving tips sourced from government websites, I bring something fresh to the table. In addition to the well-known strategies, I've uncovered and tested my own methods over the years, yielding remarkable results in my own household.

Does this warrant a purchase of my book from this website? Not necessarily. Why? It's simple: owning the book won't guarantee implementation.

Why the reluctance to implement? Because people typically favor tangible items over abstract concepts like energy conservation. This is why most energy-saving tips on other websites are freely available – attaching a price tag would likely deter interest.

Now, the crucial question: why do people invest in my energy-saving tips? It boils down to the details. On my website and in my book, I don't just offer energy-saving advice; I provide comprehensive, step-by-step guidance on implementation. What's more, I delve into detailed explanations of various ductwork installation issues pertinent to each energy-saving tip.

What's more important I give a step-by-step explanations to many ductwork installation issues related to this or to that energy saving tip!

Let’s take a look what kind of information you can get if you will purchase any of my energy saving tips:

If you implement Closing Supply Registers and Closing Cold Air Return Grills energy saving tips you will reduce your furnace cycle time! However, do not try it at home on your own! Because if you close all supply registers and all cold air return grills which you may think are unnecessary at the time, you will end up destroying your furnace or AC!
Another benefit of these chapters is that you are going to get a step-by-step guidance on how to add a floor heat and cold air return.

Double Cold Air Return Installation

Cold air return is one of the most important parts of the finished basement project. The main goal of the cold air return installation is to make air circulation. In the winter time it will remove cool air off the floor and help replace it with warm air from the supply registers, in the summer time it will remove moisture and create a healthy environment.

Double cold air returns are necessary to use in large basements or in basements with a big open space. If basement has bedrooms it would be a good idea to have a cold air return for each room, otherwise one double cold air return would be more than enough.

Of course, if you have a zoning system where one zone works only for the basement you might need more returns, but in the basement it’s always a good idea to have less cold air returns than supplies!
If you found your way to this page I can assume that most likely you are interested in the double cold air return installation. Some of the visitors of my website already purchased an access to the paid page and I’m not surprised why. Recently I've spent more than an hour looking for DIY information on how to install a cold air return in general and a double return in particular, but didn’t find anything! I dug through hundreds of websites and found out that only my website can give you a comprehensive step-by-step explanation with pictures of installation, tools and materials!
 

Basement Cold Air Return in Pictures

On this page, you can see pictures of all materials and tools necessary for installation. Pictures, which represent installation, are set in a sequence in which the installation was executed. There are 15 pictures of tools and materials and 13 pictures of actual installation.

As you can see in the picture on the left the original builder put a window too close to the furnaces! He probably thought that all this aria - from the furnaces, down to the window's end will be just enough for an entire storage-mechanical room, but a homeowner had a different opinion. However, because of that I didn't have enough room for a cold air return to the left, so I ran it to the right.

In addition I've included some brief explanations, which made this page twice as valuable!

Installation on the paid pages might not exactly describe your upcoming project. However, it will give you an important example of how this type of installation should be done. In addition, it will open the gates for as many questions as necessary to make sure that the job is done right.

Cold Air Return in Basement

A cold air return vent can help keep a finished basement warm by removing cold air and recirculating it through the HVAC system. Here are some tips for installing a cold air return vent in a basement: 

Placement: Place the vent lower on the wall or floor where cold air sinks. 

Space: Leave 6–12 inches of space in front of the vent. 

Number of vents: Ideally, have one vent in every room, but at least two or three. 

Avoid obstructions: Make sure nothing is blocking the vent, like furniture or clothes. 

Run the furnace fan: Running the fan constantly mixes cold air from the return vents with warm air in the house. 

Other ways to heat a finished basement include:Adding registers to the HVAC system

Installing a wood pellet stoveUsing electric space heatersInstalling electric baseboard heatersInstalling basement radiant floor heating 

When people are finishing their basements off, they are usually creating a mechanical room. This room is serving not only the purpose of separating noisy heating equipment such as furnace and water heater, but also serves as a storage room. From the ductwork installation point of view, it makes easier to install a cold air return.

Cold Air Return from Interior Wall

A "cold air return from an interior wall" refers to a vent located on an interior wall within a home that draws in cool air from a room, allowing it to be recirculated through the heating and cooling system, typically positioned low on the wall to effectively capture cooler air that sinks to the floor. 

Key points about cold air returns on interior walls:

Function: They pull in cool air from a room, enabling the HVAC system to maintain a consistent temperature throughout the house by recycling that air. 

Placement: Usually situated near the floor on interior walls, as cold air tends to settle downwards. Importance: Proper placement of cold air returns is crucial for efficient air circulation and comfortable indoor temperatures. 

This chapter in three instances gives a description of the cold air return installation from the inner wall, which separates two rooms in the finished basement. In this chapter you can see pictures of all necessary tools and materials and pictures of the system elements installed. All installation is divided into three steps. All installation is divided into six steps. Also you can learn how to measure, cut, put together and crimp a round pipe. The chapter has 34 pictures; 12 pages..

Return from Exterior Wall in Pictures

A "return from an exterior wall in a basement" refers to a vent in your HVAC system that draws air back to the furnace from a basement wall that faces the outside of your house, essentially acting as a return air vent, but located on an external wall of the basement; generally, this is not recommended due to potential issues with moisture and temperature fluctuations, making it best to place return vents on interior walls whenever possible. 

Sometimes you do not have a choice, but must use an exterior wall for a cold air return in your finished basement. This type of installation requires a different approach, which I have employed for this project.
On the page, you can see 11 pictures of the tools and materials and 16 pictures of installation that represent it in the step-by-step manner.

In addition I've included some brief explanations, which made this page twice as valuable!

Supply Register Soffit installation

On this page you can find information how to install a supply register directly on the supply duct for your finishing basement project...

A "supply register" in a basement refers to a vent located in the basement ceiling that delivers conditioned air (heated or cooled) from your HVAC system into the space, essentially acting as the point where the treated air enters the basement from the ductwork; it's considered a "supply" register because it supplies air to the room, unlike a "return" register which draws air back into the system. 

Function:

This chapter gives a description of a sheet metal sleeve installation that is a necessary element for a supply register that connects it to the duct. In this page, you can see pictures of all necessary tools and materials and pictures of the system elements installed. All installation is divided into five steps.
