        var letter = String.fromCharCode("A".charCodeAt(0) + index);

        //letteredIcon.image = "";
        var pinImage = new google.maps.MarkerImage("http://www.google.com/mapfiles/marker" + letter + ".png" ,
                new google.maps.Size(21, 34),
                new google.maps.Point(0,0),
                new google.maps.Point(10, 34));
        var siteLatLng = new google.maps.LatLng(point.hb,point.ib);
        var marker = new google.maps.Marker({
            position: siteLatLng,
            map: map,
            icon:pinImage,
            html: address
        });
        marker.setMap(map);
        google.maps.event.addListener(marker, "click", function () {
            //  alert(this.html);
              infowindow.setContent(this.html);
              infowindow.open(map, this);
          });

        } //else ends here
    } // if change center ends here

} //function ends here

Looks like you are reinitializing the map every time. You only want to do these operations once, like:

if( ! map ) {
    map = new google.maps.Map(        
    // ...

Make map a global var that starts as null. 

var map = null;

Also, if you are refreshing the page, you'll need to redraw all the points in a loop.
