If it’s time for a new furnace, it’s time to start doing some serious research because there are more options than ever before for buying a furnace. Your local HVAC professionals will certainly have information to help make your decision and, of course, install a new furnace, but it always pays to do some basic research on your own. Here are some key factors to consider when choosing a furnace.
Are there different types of furnaces?
There are basically three different sorts of furnaces: single and two-stage systems, and modulating systems. A single stage system is the most basic and delivers a constant heat output, which is definitely the easiest to use. Two-stage systems are more complicated because they have two different types of heat output settings and it may take some time to figure out what works best in your house.
The multi-stage furnaces work by using multiple burners and it automatically adjusts the burner flames with a great deal of precision to produce a consistent flow of heat to maintain maximum comfort.
Does the size of a furnace matter?
Most current furnaces are built of a multi-position terminal for an easier installation. Some furnaces can be installed in either vertical or horizontal configurations so it is important to check that you have adequate room for your furnace.
This size will also determine the amount of heat your furnace can put out (measured in BTUs). The area of the country you’re located in also matters. For example, if you are in a colder climate like the Northeast or the upper Midwest, you’d need to buy a furnace with more BTUs. On the other hand, if you’re in a more temperate area that doesn’t get too cold, then you can probably get by with a smaller furnace.
What about energy efficiency?
It’s fairly safe to say that any new furnace will be more efficient than older models, but choosing the most energy-efficient furnace you will definitely save money in the long run. You can look for Energy Star ratings as well as AFUE ratings (Annual Fuel Utilization Efficiency) for models powered by gas.
