After many years, your furnace may no longer work that great. If it constantly breaks down and runs inefficiently, you might consider replacing it with a new model. Choosing one doesn't have to be that difficult if you remember these tips. 

Determine What Size You Need

Furnaces can vary quite a lot in terms of their size. This attribute is important because a too-large furnace will result in higher energy costs, while a too-small unit can result in poor heating.

How do you know what size of furnace you need? Well, this really depends on the size of your home. What you'll need to do is gather the square footage totals of your home. You should then be able to find a particular furnace size that is recommended for this amount of space. 

Select an Energy-Efficient Model 

It's never fun to find an expensive energy bill in the mail. You have to heat your home during the colder months, but running your furnace constantly can cost a lot. In order to cut down on these costs, you should consider a furnace with an energy-efficient design.

You'll know whether or not a furnace is energy-efficient by assessing its AFUE (annual fuel utilization efficiency). The higher this rating is, the more energy-efficient your furnace will be. Just keep in mind that you may have to pay more initially for a more energy-efficient model. That's perfectly okay because you'll make up these extra costs in energy savings each month.

Consider Fuel Sources

Today, furnaces can be powered by various sources. Some of the most popular fuel sources include gas, oil, and electricity. Gas furnaces are pretty common in modern households, and for good reason. They are extremely easy to run and cheap to maintain over the years. Natural gas is also an extremely efficient fossil fuel to burn. 

Electric furnaces are more expensive to run each month, but they are safer compared to gas models. Oil furnaces are also great if you're looking for enhanced heating safety, as oil is not explosive. Modern oil furnaces are also pretty efficient.

If your current furnace stopped working and you're looking for a replacement, be sure to take your time with this selection. Pay attention to key factors, such as fuel source, size, and fuel-efficiency. Only then can you select a furnace that works perfectly for your property and heating needs. Then, you'll be ready for a new furnace installation in no time.
