If you suspect your door is the culprit, there are a few ways to attack this problem. First of all you can purchase a brand new energy efficient door and make sure that it is installed correctly. If you would rather not purchase a new door, some people have improved upon their old doors by installing a sheet of reflective double bubble insulation on the section of the door towards the inside and then adding a thin decorative paneling over top to keep the original look of the door. These can be secured to your existing door using screws or nails (making sure not to pierce the outside of the door skin).
Often times it is not the door per say, but rather the weatherstripping surrounding the door. This can be inexpensively purchased at any hardware store and simply tucked into the trim around the door. Sometimes if your framing is less than perfect you are going to need to get creative in order to get the best seal. Double sided sticky tape can be used on the trim where the molding sits to help push it out towards the door to create an air tight seal. If you are really looking for a quick fix, you can also install a roll of adhesive foam weatherstripping around the outside of the doors surface to help seal out a few particularly large gaps.
Don't forget about the threshold and sweep of the door which may be letting a lot of cold air in too. You can purchase a new one and have it installed, or if you'd rather just not mess with it this winter, a rolled up towel or "draft buddy" should get you through the season.
