Jenn Air Duct Free Ventilation
I am about to start a kitchen remodel and need to replace my 15 year old Kenmore 30 inch 4 burner gas cooktop, which is located on an island. We have never had any ventilation for this cooktop (don't know how it passed codes and/or inspection) and so we want to correct this with the upgrade. I feel like my only choice is downdraft for several reasons 1) I don't want the bulk and crowded feeling a large hood would bring hovering over an island in the center of a not so large kitchen 2) I don't want the extra expense associated with a hood 3) There is a bedroom directly above the kitchen and so it could not be vented to the outside anyway (guess it would just re circulated?) So, that leaves me with downdraft ventilation. A telescopic isn't an option because 1) I don't have the depth on the island to do both a telescopic and also ample bar counter space and 2) I don't want to pay an extra $800 or $900 either. My only option is a flush mounted downdraft. The appliance retailer I visited today recommended the 36 inch, 5 burner Jenn Air with the downdraft vent. Since my kitchen sits directly above a crawl space, venting through the floor would be an option. However, I noticed that there is an optional duct free vent kit with Jenn Air that can be purchase for approx. $200. So, my primary question is: Should I pay to have the cooktop vented through the floor to the crawl space or go with the duct free system? If I go with the venting to the crawl space, do I need to also vent it to the outside of the house? (I don't do indoor grilling or searing or fried chicken or anything else with lots of grease) I'm trying to figure what is the most cost effective and best option here. Does the Duct free require frequent filter changes and if so what is the cost for replacements and frequency? Not sure if this is the appropriate forum or if I should post this in the HVAC forum but any advice would be appreciated.
