1. Paint the Door

If you have an unsightly AC closet door, one of the simplest ways to help ensure the door blends in with the aesthetic of your home is to paint it.

Some people paint the door the same color as the walls in their home, helping the door to blend in, rather than to stand out. Other people simply update the existing color of the door, painting it a bright white color.

The closet door may fade or become dirty, so refreshing the paint more frequently than other doors in your home may be needed. Lastly, those who are very creative paint a mural or design on the door. This allows the door to be decorative instead of just plain. 

2. Install a Louvered Door

If the door to your AC or HVAC unit is plain, unsightly or old, you can replace the door itself. One of the types of doors that you may consider installing is a louvered door.

A louvered door closely mimics the look of plantation shutters. This is the perfect door option for AC closets that need ventilation, as the slats in the door help air to flow in or out of the closet.

This type of door is perfect in tropical-style homes or in classic-style homes, as the door fits in perfectly with both of these aesthetics. 

3. Add a Bi-Fold Door

Another type of door that you can replace your existing AC closet door with is a bi-fold door. Bi-fold doors slide and fold in half, allowing you to access the closet.

This is the ideal type of door to use in places where you may not have the ability to swing a traditional hinged door open all of the way. Bi-fold doors come in many different styles and color options, including wood doors and vinyl doors.

They can be slated if you need to ventilate your AC or HVAC closet or they can be paneled if you want to block the space off completely. 

4. Install a Sliding Barn Door

Sliding barn doors may be the perfect option as you look to replace an AC or HVAC closet door, especially if you have a country-like aesthetic in your home.

A sliding barn door is placed on a track and slides left to right or right to left, opening up the closet when needed. This is ideal if your AC is in a tight hallway where there is not a lot of space to open up a traditional hinged swinging door.

A sliding barn door typically has a lot of character to it, making the door itself a decoration. 

5. Place a Secret Door That Looks Like Shelving

In many households, homeowners feel like their home never has enough storage. If you feel like you could use more space to store books, toys or other knick knacks, a secret door that looks like a built-in shelving unit can be a creative AC closet door idea.

These secret doors look exactly like they are a built-in shelving unit that has been built into your wall, and they function as such. This provides you with shelves to store items.

However, when you pull on the shelves, the door may pull open, revealing your AC or HVAC closet. 

6. Create a Chalkboard Door

The final way to disguise an AC closet door, or to make it more decorative, is to paint it with chalkboard paint. This allows you to use the plain door as a chalkboard.

You can allow your kids to draw on the door or you can use it to write down things like events or appointments coming up or a chore list for your kids.

This allows you to take a door that is hardly ever utilized and turn it into something that is usable and makes sense for your family.
