Your newly renovated basement will feel much more habitable when the furnace is in excellent condition. The efficiency of your furnace will drop when the repair requires you to properly maintain the vent and heating system. The furnace heat can be too hot in a basement, so you must try to regulate the temperature that the furnace delivers.
You can save money by having the furnace repaired in the basement rather than having it replaced, especially if you do not need to use the furnace very often. If you are going to have your furnace replaced in the future, then the repair will probably cost less in total. Usually, the cost of replacing a furnace is on the high side and it will almost certainly not be worth the hassle of having to get rid of the old one and start over with a new one. This is why people want to know how to fix the furnace before they buy a new one. Many times, they can get some parts for free from the contractor who did the job. Having the furnace repaired for you will save you money, since you will not have to pay for labor costs.
If you need to replace the furnace in your basement because it is outdated, then it is necessary to maintain it well. Your furnace should be cleaned and oiled at least once a year and it should be checked for leaks and give an estimate of what it will cost to have it repaired. The good news is that this will not take up too much of your time. It will also save you money since you will only be spending a small amount of your money on a repair than on a new furnace.
