If your furnace has reached the end of its life, it is time for you to start looking into replacing your furnace. When the time comes for a furnace replacement, there are a few different factors you need to take into consideration.
Factor #1: Type of System Layout
First, you need to consider the way that your current system is laid out and if you want that same layout. You can have either a packaged system or a split system layout.
If you have a split system layout, you more than likely have either a basement, attic or crawlspace where you can put your equipment. With a split system layout, you are going to have a condensing unit and coil in addition to your furnace in the same space. This will allow you to enjoy both heating and air conditioning all at once. This type of unit does require you to have some extra space.
If you don't have a ton of space, you can go with a packaged system. With a packaged system, the unit is stored outside, so you don't have to dedicate inside square footage to your heating and cooling system. Additionally, with a packaged system, the heating and cooling elements are all contained within one unit.
Factor #2: Fuel Source
The second factor you need to consider is how you want to provide fuel to your furnace. The type of fuel source you choose depends upon the fuel sources that are available to you, as well as what fuel source is most economical within your area.
The cleanest and usually most cost-effective fuel source for your heated is natural gas, if you have a natural gas line that runs to your home. If you don't have access to a gas line, you may want to go with either propane or natural gas. The thing with either propane or natural gas is that you will need to store the fuel source on your property somewhere.
Your last option is electricity, which can be efficient, but also costly.
Factor #3: Speed Blowers
Third, you need to consider what type of speed you want your blower home to have. You can go with a fixed speed blower, but that means that the blower is always sending out air at the same speed throughout your home. Or you can go with a variable speed blower, which is more popular, as it allows you to vary the speed with which air is sent through your home.
When it comes to purchasing a new furnace, you need to consider the layout, the fuel source, and what type of speed blowers you want. Once you decide these things, it will be easier for you to choose the exact furnace you want.
