Venting a Range Hood Outside

Range hoods are common in the sense that the majority of kitchens have them, but what many people do not have in their homes are range hoods that vent the air outside of the house as opposed to simply filtering the air and recirculating it throughout the kitchen. Air ventilation is very important in any kitchen, primarily because of the grease, smoke and debris that crowds the air as a result of cooking and baking. Without proper ventilation, these air pathogens may eventually lead to health problems or food borne illness, so proper ventilation from the start is a necessity.

If you already have duct work built into your home, installing your new range hood should be a pretty simple process. On the other hand, if you were previously using a ductless range hood and are looking into switching to a vented range hood that will actually deposit the contaminated air to the outside of the house, you may need some additional construction and design work to make sure that everything is properly set up and ready to go.

Step 1:
Before beginning the ductwork and vent hood installation process, make sure to remove any unnecessary body parts from the hood such as the filter, fan, light housing and electrical work

Step 2:
Lift the hood to its permanent location above the range and outline the section that will be knocked out for the duct with a pen or pencil. The knock-out can also be made through the top for wall mounted vent hoods.

Step 3:
Saw out the rectangular piece from the wall where you made the outline, and drill a hole next to this box for the electrical line.

Step 4:
Repeat the same process for cutting a rectangular hole on the outside of the house. If possible, remove the block from the outside wall from inside of the house to achieve better alignment with the first hole.

Step 5:
You can create a mounting plate by aligning a piece of PVC plate to the hole against the inside of the kitchen. You can affix the plate with screws and a silicone adhesive as necessary.

Step 6:
If possible, get someone to help you hold the vent hood in place as you feed the cable through slot next to the knockout hole, and clamp the range hood into its permanent position against the wall and above the range.

Step 7:
Now it’s time to install your duct work. You can do this by starting with the rectangular hole on the outside of the house. Slide the exterior vent cap into the hole and secure with screws. As necessary, apply a silicone sealant around the edges of the cap to ensure no moisture can seep through on wet or rainy days.

Step 8:
On the inside of the wall, ensure electrical function before sealing off the duct work. Use a wire not to conceal the electrical wiring, and attach the vertical cover to hide the ductwork and finish installation.

Step 9:
Finally, install the body parts back into the range hood and enjoy a cleaner, more breathable kitchen space!

How to Keep Your Kitchen Cool

This guest post is by Lewis Jackson of Air-N-Water.

G1   Summer cooking can be a real pain. Not only is it hot outside, but the heat from your stove and oven adds to it, raising the temperature even higher. Even worse, if it leaks out into the adjoining rooms, it can wreak havoc on your electricity bills. The additional heat triggers your thermostat, signaling your air conditioner to work overtime in an attempt to maintain its temperature settings. Besides switching to cold foods or restricting your cooking to late night or early morning, the best way to avoid these problems is either to vent the heat, cool your kitchen, or both.

Ventilating Your Kitchen

If your home uses a central air conditioner, ventilating your kitchen can be difficult. The natural solution, opening a few doors or windows to circulate the air with a cross breeze, isn’t practical, so the best solution is to capture the heat before it can dissipate, through a ranged hood. They use fans to draw in the hot air from the stove and funnel it out of your home so it doesn’t affect the rest of your home or throw off your cooling system.

 Cooling Your Kitchen

Ventilation keeps the heat from your kitchen appliances from interfering with the temperature settings in the rest of your home, but staying cool while you’re cooking most likely requires spot cooling. Spot cooling is used to reduce hot spots in buildings. Small coolers are brought in to provide additional air wherever local conditions prevent central AC systems from lowering temperatures effectively.


In kitchens, spot cooling is normally performed by portable air conditioners or window air conditioners. These are low-cost, single room units that utilize less electricity that central air or split AC systems and remove excess humidity from the air, which makes it easier for your body to regulate its internal temperature. Some units, like the NewAir AC-12200E and the NewAir AC-14100E, actually use the collected moisture to cool the compressor, boost their efficiency rating, and reduce their electricity consumption.

To determine what sized air-conditioner will work most effectively in your kitchen, measure its area (length x width) and compare to the chart to the right. By the standards of most rooms, the average kitchen is pretty small, only 150 square feet, which is why spot cooling makes sense as an economical solution to your heating problems. 150 square feet only requires 5,000-6,000 BTUs (British Thermal Units) of cooling power, so a small unit is all that’s needed to handle the job. To keep costs under control, only activate them as needed, and add 4,000 BTUs to your rating in order to compensate for the activity of your stove or oven.
