Сделал так. Консоль чистая...

$(document).ready(function() {

  var getData=new Promise(function(resolve){
		Papa.parse("/testArr.csv", {
			download: true,
			header: false,
			success: function(results) {
				resolve(results.data);
			}
		});
	});

  $('.start-calc').click(function changeFunc() {

    var type = $('#type-okno').val();
    var gluh = $('#type-otkidnoe').val();
    var img  = $('#okno-img');
    var imgtitle = $('#img-title');

    function checkArr(arr,a,b) {
      return arr[arr.findIndex(el=>el[0]>a)][arr[0].findIndex(el=>el>b)];
    }
		getData.then(function(data){
			var price = checkArr(data,7,4);
      console.log(price);
		});

  });
});
