Having a furnace with a humidifier can ensure that the air in your home isn't dry. However, does that mean all furnaces come with humidifiers? We have answered that question in this article.

Typically, your furnace won't have a humidifier unless installed with the HVAC system. Humidifiers are an additional unit installed into the ductwork to add humidity to the air as it passes by. They are helpful to circulate moisture into your home to avoid dry air. 

During the winter months, the air can become extremely dry. A humidifier can help solve this problem, especially if one is equipped in your humidifier. This article will take a closer look at the benefits of having a humidifier in your furnace. In addition, we will discuss how to tell if your furnace already has a humidifier, so read on!

Do All Furnaces Have Humidifiers (And Do They Work?)

The short answer is no; not all furnaces have humidifiers. However, suppose your furnace is already equipped with a humidifier.

In that case, it will work during the winter months to add humidity to the air and help alleviate problems associated with dry air, such as static electricity, dry skin and lips, and a scratchy throat.

If you are thinking about installing a humidifier in your furnace, consider a few things. First, you need to decide if the humidity level in your home is too low.

You can do this by using a hygrometer, a tool used to measure the amount of moisture in the air. If the humidity level is below what it should be, a humidifier will help increase it.

A second consideration is how often you use your furnace. For example, if you run your furnace every day in the winter months, a humidifier can add enough moisture to the air that it won't need to be on as much. Also, many homes generally have a higher humidity level in the spring and summer months.

You may have noticed that many newer homes have furnaces with a built-in humidifier. These furnaces are becoming more popular in recent years due to an increased focus on indoor air quality and environmental factors.

Do You Need a Home Humidifier?

On the other hand, some homes may not need a humidifier at all. For example, if you live in an area where the humidity is already high, the air circulating in your house could be sufficient.

If you are looking for a way to improve your home's humidity levels without spending money on additional equipment, there are other options. For example, you can reduce the number of times that your furnace runs per day, which will help increase the humidity in your home. In addition, you can also add a humidifier to your furnace if it doesn't have one.

In addition, you can buy a separate humidifier for your home. This unit is alone and isn't a part of the furnace itself. Instead, it works by introducing water into the air, adding humidity to the atmosphere.

Another option is to get more house plants in your home. Plants can help increase the humidity in your home by releasing moisture into the air. Again, it will help if you use wide pots to ensure proper drainage.

How do you tell if my Furnace has a Humidifier?

There are a few options when it comes to checking if your furnace has a humidifier.

First, you can check the owner's manual for specific instructions on checking. Another option is to contact the manufacturer directly and ask them how you can tell if your unit has a humidifier.

Typically, it is easy to tell once installed because the humidifier is visible. However, if you aren't sure if your furnace has one or not, it's best to err on the side of caution and assume that it doesn't.

A humidifier is usually its box that is attached to the furnace. The water lines from the humidifier can run to your furnace or attach to a single zone in the house.

Where is the Humidifier on my Furnace?

In general, humidifiers are located on the furnace itself or outside it. If your humidifier is attached to the furnace, then you will need to take a closer look at where it's located. Some humidifiers attach through a side panel, and others work by redirecting air from the furnace. The humidifier will also have ductwork attached to it.

How Much does it Cost to Have a Humidifier Installed on your Furnace?

The price to install a humidifier on your furnace can vary. The prices vary due to the size and type of your furnace. In addition, it will depend on what type of humidifier you want to install. Nonetheless, expect to pay on average $400 to $800 to have a humidifier installed on your furnace.

If you are looking for a separate humidifier, the price range is usually between $100 and $300. If you can't decide whether to get a separate unit or have a humidifier installed directly into the furnace, both have pros and cons.

Installing a unit into the furnace will offer more convenience since the ductwork is already set up. On the other hand, you can easily replace or remove a separate humidifier if you so decide.

In addition, a humidifier that is a part of the furnace will be more efficient. However, as you can see above, it will be more expensive.

It is essential to determine how long you will live in the home. If you plan on moving within a couple of years, it may not be worth investing the higher amount of money in installing one directly into the furnace.

When Should you Use a Furnace Humidifier?

Typically, if your humidity drops below the 30% mark, it is good to use your humidifier.

However, many people prefer to use their humidifiers in the winter when the air is dry and cold. In addition, the furnace can help raise the humidity levels during this time since it works 24 hours a day.

You should contact an HVAC professional if you aren't sure when you need to use your unit or what settings are best for the humidity levels in your home.

How Long do Furnace Humidifiers Last?

How often you use and maintain your humidifier will determine how long it will last. However, on average, you can expect to get 2-3 years out of your humidifier before you need to replace it.

It is essential to have your humidifier cleaned and maintained regularly to ensure that it is running correctly and to help it last longer.

Are Furnace Humidifiers Necessary?

There are mixed opinions when it comes to furnace humidifiers. Some people feel that they are necessary to maintain the humidity levels in their home, while others feel that they are not necessary.

If you live in a temperate climate and your home already has 30-50% humidity levels, you may not need a humidifier.

However, if you live in a dry climate or your home's humidity levels are below 30%, then it is recommended that you use a furnace humidifier.

How do You Know Your Humidifier is Bad?

The humidifier's fan should also turn on when you turn on your furnace. If the fan does not come on right away or is making noise, there has been a problem since turning off the unit.

Generally, if your humidifier starts to make unusual noises, it is time to check it out. In addition, if there is water leaking from the humidifier, then it is time for a repair. Or, if the humidifier isn't putting out enough humidity, you'll likely need to clean or replace it.

Lastly, if you have a humidifier and you are experiencing dry skin, then your humidifier might not be doing its job. Check to see if the humidifier is running and check your humidity levels.

If you have had your humidifier for a while and your humidity levels aren't rising, then it is a tell-tale sign that it is time for a replacement unit.

Overall, there are several benefits to having a furnace with a humidifier. However, if you don't plan on living in that home for a while, it may not be worth the investment. Instead, you can buy a separate unit for significantly less money than you can then take with you to your new home.

Nonetheless, suppose you live in an area with dry air during the winter. In that case, it is worth getting a humidifier in your home, whether they install it in the furnace directly or a completely separate unit!
