Your cabinet company will provide the wood exterior and many have the liner and blower already designed to work together as a predesigned ''plug and play'' solution. 5-7K for the integrated solution.

If you want to individually purchase separate components to work together, you need your installer and designer to vet if the combo will actually work. You cannot have wood directly over a cooking surface, so the liner must be the right size to work with the wood surround, and be planned from the beginning to be installed at the correct height. Then you need blower, etc. There are a lot of combinations, but not all work together or are available in all locations. You could pay 2K or you could pay 10K. It will depend on each component choice.

You need to be working with your installer and designer personally.

The cabinet company asked me which range I planned on purchasing. This is a little confusing

They asked about range because you size range, hood and hood surround to work properly together. To get the look you want will cost about $10k total. The larger the range the higher the hood cost. Noise level of fan is something to be concerned about too. Is your kitchen open to say family room? Lots to consider. Best done before construction starts due to fan venting requirements. What size range have you specified width and number of burners? High1end? Gourmet level gas? These questions all factor in.

Just a few things to consider and to discuss with your contractor and cabinet supplier. 1. Do you have venting for the hood to the outside? If not, you will need to discuss this with your contractor to see if it is possible and what the cost would be. 2. The cabinet company needs to know what width and type of range you will be purchasing. The standard is 30" wide. Almost all cabinet companies will have hoods like what you have shown in the photos above that will coordinate with your cabinets. 3. In addition to the hood you will need a liner, but that should also be available through the cabinet company. 4. One last item you will need is the blower. Most cabinet companies also sell the blowers, if yours does not, your electrician should be able to purchase the appropriate blower for you after your cabinet company gives him the specs for the hood you are purchasing. When purchasing the blower be sure to ask about the noise level. Usually the more expensive the blower, the quieter it is. Good luck!

We are looking at a standard gas range 30 inches wide with 5 burners (LG NX58K7850SS). I don't believe there is venting to the outside but I will double check with our contractor. The kitchen is open to the dining room. Happy to take suggestions on which range hoods will work for our situation.

A hood like that is overblown in both style and expense for a consumer grade range like that. It belongs above at least a 36" pro style range. A plain Jane $400 under cabinet stainless hood would be more appropriate. Especially if you can't vent externally.

I agree that style of hood looks best with a larger stove maybe some pics of your kitchen will help

One other caution, check your building codes because in my neck of the woods, they have strict requirements for ventilation based upon gas cooktops. Next your appliance store should be able to work with your cabinet maker to find a quiet ventilation system. And if you don't have exterior ventilation for that gas cooktop then you should consider induction because an unventilated gas cooktop is a recipe for carbon monoxide poisoning and death of your entire family. Induction is a great alternative to gas.

Carbon Monoxide Poisoning: Gas-fired Kitchen Ranges (AEN-205)

Gas kitchen ranges releasing unvented combustion products into the kitchen are common in many homes. Studies show carbon monoxide concentrations in the kitchen are elevated when the stove is used without using the range hood.

What pollutants are released from a kitchen range? The main pollutants are carbon monoxide, carbon dioxide, nitrogen dioxide, and water vapor.

How serious is carbon monoxide from kitchen ranges? Carbon monoxide is a deadly toxin. In one study, 51 percent of kitchen ranges tested raised CO concentrations in the room above the EPA standard of 9 parts per million. Five percent had carbon monoxide levels above 200 parts per million.

How serious are the other pollutants? Nitrogen dioxide is a respiratory irritant produced when the nitrogen in the air combines with oxygen in the burner. The high number of gas ranges, the tightening of homes, the use of gas ranges to heat the home, and the increased incidence of asthma in the U.S. suggests a link between unvented gas heaters and health problems.

What about carbon dioxide and water vapor? Carbon dioxide is a non-toxic gas produced during complete combustion. At higher concentrations CO2 can cause drowsiness, headache, and lead to a “stuffy” feeling in a home. Excess water vapor can lead to problems with mold, wood rot, and peeling paint.

How much carbon monoxide is produced by a kitchen range? Carbon monoxide from kitchen ranges is a common reason for elevated concentrations of CO in homes. Kitchen ranges are required to produce no more than 800 parts per million (ppm) carbon monoxide in an air-free sample of the flue gases. Continued operation of a kitchen range producing 800 ppm in a tight house without extra ventilation will cause carbon monoxide levels to rise quickly to unacceptable levels. Field technicians report most kitchen ranges can be tuned to produce less than 50 ppm.

How can the adverse health effects from using a gas range be reduced?

Have the furnace tuned for combustion safety by a qualified specialist.
Follow operating instructions carefully:
Do not block air vent holes.
Do not cover the vent holes on the bottom of the oven with foil.
Keep the unit clean.
Do not operate with the oven door open.
NEVER USE A KITCHEN RANGE TO HEAT THE HOME!
Always use the kitchen range hood fan, vented to the outside, when operating the kitchen range.
Have the range serviced when:
Burner flames are not blue.
The burners do not light properly.
The burners or pilot produce soot.
Carbon monoxide concentrations in the house increase during operation of the range.
Evacuate the house, and call for assistance from outside the house if there is a smell of natural gas or LPG.
Install a fire extinguisher, smoke detector, and carbon monoxide detector in the home.
How important is installation and use of an exhaust hood vented to the outdoors? Very. Even when the kitchen range is properly tuned, there will be some carbon monoxide produced along with carbon dioxide, nitrogen dioxide, and water vapor. Kitchen range manufacturers recommend installation of a range hood to exhaust the combustion products along with cooking odors, grease, and moisture produced during cooking. Failure to use the range hood exhaust fans results in indoor air pollution.

What should be considered when purchasing an exhaust hood? It must seal tightly and vent to the outdoors, operate quietly, and have sufficient capacity to remove cooking fumes. A caution: exhaust fans depressurize the house and may cause downdrafting of vented furnaces, water heaters, boilers, fireplaces, and vented room heaters. Adequate make-up air into the house must be provided for the kitchen exhaust hood. Have a qualified heating contractor install the exhaust hood and run a “worst case” downdrafting test to ensure that all the systems work correctly.

Why can’t the oven door be opened to heat the kitchen?

The broiler and oven burners are designed to burn with the door closed.
Opening the oven door disrupts the air flow pattern, and high concentrations of carbon monoxide may be produced.
The oven burner is not designed to operate continuously, and can overheat.
Kitchen ranges are designed for intermittent operation. Range standards allow concentrations of carbon monoxide that, under continuous operation, could create serious health problems. The longer the range operates, the more carbon monoxide produced.
When the oven door is open, heat from the oven flows out the front, and can melt the control knobs or damage the controls.
I have an older kitchen range that sets off my carbon monoxide detector. Will buying a new range correct the problem? Since 1926 kitchen ranges have been allowed to emit up to 800 ppm of CO. A new range may emit as much or more than the old range. Have the old range inspected and tuned by a qualified contractor, one with instruments which measure for carbon monoxide in the flue gases. If you replace the range, have the new range adjusted for low carbon monoxide emissions after installation in your home!

How are ranges modified to burn natural gas or LP? By changing the gas regulator and orifices. Natural gas and LP have drastically different burning characteristics. If the changes are not correct, extremely high levels of carbon monoxide will be produced along with an increased risk of fire or explosion. Conversion should be made ONLY by a qualified contractor, with proper equipment, training, and parts. For a safe conversion, the contractor must measure for carbon monoxide and tune the range for minimum carbon monoxide production after conversion.

What about electric ranges? The electric elements in electric ranges do not produce combustion pollutants. Burning food produces smoke and carbon monoxide, and can cause smoke detectors and carbon monoxide detectors to alarm. So can self cleaning ovens during the clean cycle. Carbon monoxide is toxic, so if CO reaches concentrations high enough to set off an alarm, the alarm should be taken seriously. Open windows and leave the house until concentrations drop. If anyone experiences health problems, medical attention should be sought.

custom hoods need a hood insert, your range will specify hood requirements, your cabinet maker will design and make said hood cover, you need to purchase insert from appliance store and need to coordinate specs etc
ventahood is what we have and it is quiet and works well

Is the location of your range on an outside wall? If so, make it exist to the outside. Or it might be able to exist up through the roof line. Check on this. Should have been part of your basic plan.

Auto check, I meant exit. both times!

I spoke to our contractor and he said he plans on taking care of the duct work to get the external ventilation. The wall on which the hood will be placed backs to the garage and we are planning an addition over the garage at some point. Attached is the proposed kitchen layout but I don't love the hood. I'd rather go with something like the attached but this company does not provide it. It looks like I can buy the furniture piece with the blower and the liner but I'm not sure if I'll need anything else. Any help would be appreciated

What else you need depends on if you like a LOUD blower or not, and what the liner contains. You may also need an insert with the lights, and filters. You will need to make sure that it is all suitably sized for your project, so that no part of it is closer than 30" above your cooking surface.

Ductwork CAN NOT travel through a garage unless it is encased in drywall. It can not be flex duct. It needs to be rigid ducting only. The further from the source that it exits, and the more turns, the weaker the suction will be, and the less it will suck away the baddies. The best route is the shortest route. If the route is over 10', you need more CFM. You may need a larger duct as well. Plan on 12" if you want 1200CFM, and size down according to length and turns. You WILL be REQUIRED to have a MUA system, and that has to be planned into the budget as well. You can't have one without the other.
