I dislike side by side refrigerators so I replaced the one that came with our current house. French door refrigerators place all of the bins at a much better level. We have a stand alone old 5 cubic ft freezer so I can stock up. I researched refrigerators extensively.
A larger one is nice even for empty nesters because we freeze portions and have many leftovers. In the door ice/water is a must for Florida if you want cold drinking water ad lib. Up north it may not be wanted.
It came down to two brands for me. Samsung or LG based on reliability and features.
Both have the feature where the freezer door has some lift to it when opened- try out those doors in the store and you will understand. Also think about solid instead of wire freezer shelves- food particles may end up hidden. And door storage can be useful.
Consider the need for a lot of ice versus where the icemaker is. Also check for shelves that slide/fold so tall items can be placed on more than one shelf.
Door in door is more expensive, as is counter depth for the same size. Neither useful- we easily open the door to get stuff on one side. I understand above poster’s issues. We opted for the three door model with an across the width drawer. Less expensive than one with a separate door for that. Pros and cons- we need to open the whole refrigerator to access that drawer but can see its contents whenever we open the refrigerator- no out of sight out of mind.
Little things can be good or annoying. I liked the Samsung rounded handles better than the LG’s (or other brands) plus the other details. I also had checked the type of cooling- dual or some such (a few years ago). I have seen refrigerators that look good but are awkward to open- recessed handles that I find difficult for right versus left.
Sears has had good information about many brands. Likewise check other sites for info- online and in the store. You do not need to buy where you look. Catch the sales and price matching. Check on delivery/haul away charges. We got a great price from hh gregg- out of business now
Ours is a Samsung RF28HF… Not too big for two of us and energy efficient, quiet… You need to go bigger than 24 cubic feet to get nicer features/quality. Ours listed for $3000 +/- but cost under $1700 after sale price/rebate et al almost four years ago.
I/we chose different brands for different appliances- no need to use the same brands in your kitchen. We did go all stainless to match the current GE stove and over the range microwave oven that are still going strong.
Go “kick some tires” at several stores. Read reviews. Some of those high end refrigerators have more issues than the free standing upper mid range brands.
Be sure to check dimensions that will fit your space as well!
