Installing a new furnace can be performed by a good handy type homeowner. There are several things that you will need to fully understand. I will not be able to convey precisely what I know in an article along these lines, but I will attempt to give delivering things that will help the handy person so as to overcome some of the major hurdles that can be encountered when changing a furnace.
The first thing for you to do when changing out you furnace is to research different new models. Do not assume you have to same BTU furnace as you have. Could very well be much better off with a smaller furnace, especially if you are changing out an adult inefficient furnace with a higher efficiency design. Also check that the dimensions of the new furnace will allow it to needlessly fit into the same space, and adapt to the existing supply and return duct deliver the results.
Next you will have to remove typically the old furnace. When you do this make certain to carefully plan for the installation of the revolutionary furnace. By doing some careful planning you may create the hookup of the new furnace rather easy. Do not take apart more then is recommened to remove to old furnace. Then position the new furnace to make the most of as much of the existing parts within the old furnace as possible.
Remove the electrical supply as well as gas or oil lines. Then carefully disassemble the supply and return duct work. Very often the return duct work can simply be reattached to the new furnace after cutting the appropriate hole within the side of the furnace. As long as you certainly air conditioning on your furnace you might just strap up the supply duct-work temporarily with the ceiling and hold it there till you can get the new furnace under it again. Many new furnaces are certainly not as tall as the old ones, and that means you will either need to block up any furnace and shorten the return duct, or you have got to attach it to the existing duct work then support the supply duct and build new duct to move into to the old supply. Duct-board material is easy to utilize and will work well for doing it.
If you have air conditioning on you system you are able to often support the indoor coil with the duct-work and just make the swap beneath it. If you cannot do that then you will need to get a professional to help you that allows you to pump down and recharge the system. That process takes special license and special equipment to finish the same task.
Now that you have everything removed out of your furnace and marked so you know how it dates back together, you can slide the new furnace ready. I usually start by hooking up this supply duct, then the return duct. Once this pair major things are in place then the gas line and wiring can be installed to the new furnace. I usually make sure you use an approve flexible gas line so that the piping part is easier. Often the electrical lines will fit on the new furnace, however if not then changing the wires really is not that hard.
Also MAKE SURE to keep the manufacturer directions!!! Inside the installation manual there are actually very clear installation instructions. Make sure to follow all the directions exactly. There also are instructions for ones start up of the furnace in right now there, those instructions will help you through the commencement up and check procedures. Make sure to help keep the installation manual for future reference. You can also get troubleshooting procedures and flow charts in now there that will make troubleshooting a problem sometime soon much easier.
After over twenty years of installing furnaces I still emerge the installation manual and read it, when they are always changing things that are deparately needed for proper operation. However after these many years I have also been able to trim the time up to less then a day for some installation and usually always less then two days for a good difficult one. Your time will be alot more then that, but with some planning ahead and creating lists from the materials and tools needed you can still finish the job well and in a respectable amount of their time. Or you may choose to have some else get it done for you….
