Utilities can be high, especially in the winter due to your house getting colder because of the weather. In trailers, they can get the coldest and it can cost more to keep it warm because cold air can come from anywhere, such as the heating and cooling ducts, the windows, from under the doors, or if something gets under the trailer and tears out the insulation. This can allow cold air to come up under the floors and cause the floor to stay freezing. Also watch your pipes because if they freeze and break or bust, your electric bill and your water bill will go up, and you can have a very big bill on both of them.
Same thing can go for old houses. They can also cause a lot of air to get in the house. They are also hard to keep warm because of all the air, and you have to raise the heat up just to get the whole house warm and to stay warm. Here are some ways you can save money on the utilities: You can put some new insulation under the house. This will help the house stay warm and you won't have to raise up the heat just to keep the heat inside. This will also help you save money on your heating bill whether it is gas or electric because you will not use as much.
You can put up plastic on the windows so the heat will not get out and the cool will not come in. This way you can keep your temperature at 70 degrees, and it will not freeze your house over night. You can also put plastic around the heating and cooling ducts that are under the house. No heat will get out of the duct and the heat will stay in your house. Put something under the doors to keep the air from getting out or air from getting in and cooling under your house. Also put seals around the doors so the cool air cannot get through the cracks in the doors.
If you use space heaters, they can cost you a lot of money if you use it a lot, so cut down on using it after you get your house sealed up tight and you will not get such a high bill. If you have a heating and cooling unit, make sure the holes are on there right and that it is tightly on there because air will get out of the unit and cause you to have a high bill. When this happens, you are heating the under part of the house and it will cost you money. If it is on there and there are no holes and the unit is working right, you will save money because it will not take so much to keep the house heated.
