Now that you know how to install a furnace in the attic, keep reading to learn if it's a good idea. We will also cover how much it costs if it's safe and other relevant questions.
What Are The Benefits Of An Attic Furnace?
Having your furnace in the attic can save you a lot of space. Usually, people don't use the attic much. Often, it will be either empty or for excess storage. As a result, the attic can be the best spot for a furnace as it will leave your closet and basement clear for other purposes.
Furnaces can make a lot of noise. Putting it in the attic will make the noises harder for you to hear on the main floors of the house. As a result, you will have a much quieter, peaceful home.
When installing an attic furnace, the installation can be cheaper. This is because you can vent it right through the roof and not have to do as much ductwork. By doing less ductwork, you save money.
Attic furnaces can also provide more even heating distribution throughout the house.
Is It Bad To Have A Furnace In The Attic?
This question doesn't have a clear-cut answer. If your attic is spacious and air-conditioned, it can be great. However, an attic that gets extremely hot in the summer and, if small, can cause functionality issues.
A high-efficiency furnace in an attic that is small and unconditioned will not be effective. This is because there tends not to be enough air for the machine to work correctly. Your furnace will have to work harder in the attic because warm air rises naturally, and your furnace will have to force the warm air to go down rather than letting it rise naturally. This can make your energy bills go up.
Damage from Extreme Temperatures
High-efficiency furnaces shouldn't be installed in attics because they can get damaged easily when exposed to extreme temperatures. If you have an attic that is conditioned, you won't have to worry about this problem.
Unable to hear if there are issues
Even though having it in the attic can be quieter, this can be a negative thing. You may not hear the furnace making noises when it has problems. As a result, problems may go unnoticed for a long time before being fixed.
The ductwork in the attic can have more issues. This is because attics can get extremely hot. This heat can cause small holes and leaks. This can make your air conditioning bill higher, as your AC will be less efficient.
Another negative thing about having an attic furnace installed is that there are more regulations than there are for basement or closet installation. Closet installation is easier to service than attic installation, but there isn't much difference.
Installing An Attic Furnace
When you install an attic furnace, it is best to have a professional install it. This is because there are so many regulations that it can be hard to make sure you follow all the rules.
Regulations might be slightly different depending on where you live. However, you can click here to see some of the regulations involved in attic installation.

Always check with your local government building authority for information on permits and requirements.
For instance, you cannot install an attic furnace on carpet or tile, and there cannot be anything combustible around the unit. Wooden house beams are okay, though.
If you decide to install it yourself, make sure to have someone come in and check that your attic is suitable for a furnace. While older furnaces were okay to be installed in an attic, many newer high-efficiency ones can be damaged if they aren't in a suitable environment. Many people learn that they have to purchase a subbase to put it in the attic because there are such strict regulations on what material the unit can be placed down on.

How Do You Know If Your Furnace Is Dying?
When a furnace is dying, there are a lot of signs that will let you know. One thing is that your furnace will become less efficient, and your heating bills will go up. Another sign is that your furnace will start needing more repairs.
You also may start hearing popping, banging, and all kinds of weird noises coming from your machine. The blower will also start turning off and on a lot and making excessive noise.
