Aromatic Plants Near Air Conditioners: Good Or Bad Idea?

If you're looking to improve the air quality and scent around your air conditioner, consider planting some greenery. However, not all plants can survive the fluctuating temperatures, dry air, and heat that air conditioners produce. The heat from an air conditioner can be detrimental to plants, causing issues like leaf drop, yellowing leaves, leaf browning, drooping, and slowed growth. To avoid these issues, it's recommended to keep plants at least 3 to 5 feet away from the unit. Additionally, avoid placing items on top of the condenser unit, as this can restrict airflow and cause damage.

If you're looking for plants that can survive in an air-conditioned environment, consider air plants, snake plants, pothos, peace lilies, ZZ plants, ferns, and cacti. These plants are known for their ability to tolerate fluctuating temperatures and dry air.

For adding a pleasant fragrance to the air around your air conditioner, you can try using sachets with dried and crushed herbs, lavender blossoms, cloves, or sandalwood paste. Placing these sachets behind the sensors or on top of the vents can help disperse the scent. Alternatively, you can create a mixture of lemon extract and water in a spray bottle and spray it into the vents for a refreshing lemon scent.

Insects are attracted to moisture, so prevent moisture buildup around the unit

Insects are attracted to moisture, so it is important to prevent moisture buildup around your air conditioning unit. Here are some ways to do this:

Keep the Area Around the Unit Clean and Clear

Keep the area around your air conditioning unit clean and clear of any debris, plants, or junk. This includes removing leaf piles, cutting back low-hanging tree branches, and ensuring the unit is not surrounded by plants. Bugs are attracted to the additional supply of plants, and debris such as leaf piles provides a great home for insects. Keeping the area clear will help prevent insects from being drawn to the unit and provide them with fewer hiding places.

Move the Unit Away from Plants

If your unit is surrounded by plants, consider moving it to an area with grass, stones, or pavement. An area surrounded by plants will draw in more bugs than one with grass, and an area with grass will attract more insects than one with stones or pavement. Moving your unit to a less plant-heavy area will help reduce the number of insects drawn to the unit.

Fix Any Water Leaks

Cockroaches and other insects are always on the lookout for water, so it is important to fix any water leaks from your unit. Check your hose spigots and ensure they are closed tightly. If you notice any water leaking from your condenser, this could be a sign that something is wrong with your air conditioner, and a professional should be called to fix it.

Keep Gutters and Downspouts Clean

Routinely cleaning your gutters and downspouts is important as the buildup of dust, leaves, and debris over the summer months can create an inviting home for insects. Keeping these areas clean will help to deter bugs from making their nests near your condenser.

Install Screening or Use Cardboard to Cover Gaps

If your AC unit doesn't fit well and there are gaps, you can install specialised AC screening to encase the unit and keep bugs out. Alternatively, you can use cardboard to cover the gaps. Cut cardboard to fit any size or shape gap, then use duct tape to secure it in place, creating a barrier that insects cannot penetrate.

Seal any noticeable cracks along the ductwork with duct tape

If you want to add a fragrance to your air conditioner, there are several DIY options you can try. However, this instruction will focus on sealing any noticeable cracks along the ductwork with duct tape.

Before you start, it's important to prepare and ensure you have the right materials. Wear a mask and safety goggles to protect yourself from fiberglass particles when cutting and handling insulation. You will also need duct tape, ideally aluminum foil tape with a "UL" marking, indicating it's approved for residential ductwork. Additionally, you may require duct mastic, a basic paintbrush or putty knife, and fiberglass mesh tape for reinforcement.

Now, let's get into the steps for sealing those cracks:

• Identify the cracks: Inspect your ductwork and locate any noticeable cracks or leaks. Take note of their locations and assess the severity of the cracks.
• Measure the duct circumference: Using a measuring tape, find the circumference of the duct. This will help you determine how much duct tape and other materials you'll need.
• Gather the necessary materials: Based on your assessment of the cracks and the duct circumference, gather enough duct tape, as well as duct mastic and fiberglass mesh tape if needed.
• Tear off strips of duct tape: Tear off long, continuous strips of duct tape that will fully cover the seams running vertically along the duct. Ensure the strips are long enough to provide adequate coverage.
• Apply the duct tape: Firmly press down and smoothly apply the duct tape over the cracks or seams. Use your utility knife to cut the tape roll loose once you've applied enough tape.
• Reinforce with duct mastic: After taping, apply duct mastic to the joints where the elbows connect to the duct. You can use a paintbrush or a putty knife for this step. Water-based duct mastic is recommended for its ease of cleaning and longevity.
• Add fiberglass mesh tape for larger cracks: If the cracks are more severe or gaping, use fiberglass mesh tape to reinforce the mastic. Small cracks should be fine with mastic alone.
• Repeat as needed: Continue these steps until all noticeable cracks and leaks have been addressed.
• Allow drying time: The mastic will typically dry within 12 to 24 hours.

By following these steps, you can effectively seal noticeable cracks along your ductwork, improving the efficiency of your air conditioning system and maintaining optimal air quality in your home. Remember to take the necessary safety precautions and use the appropriate materials for the best results.

Install a protective screen around the vents to keep bugs out

If you're looking to prevent bugs from getting into your home through your air conditioning unit, installing a protective screen around the vents is a great idea. Here are some detailed instructions to help you get started:

Choose the Right Screen Material:

Purchase an insect screen or mesh that is specifically designed to keep bugs out. This material should allow for sufficient airflow while acting as a barrier against insects. You can find these screens at your local hardware store or online. Make sure to check your local building codes before purchasing, as there may be specific requirements for the type of screen or mesh you can use.

Measure and Cut the Screen:

Remove the vent cover by unscrewing it. Use the vent cover as a template to cut the insect screen to the correct size. Alternatively, you can measure the height and width of the vent hole and add an extra inch to each dimension. Cut the screen accordingly.

Install the Screen:

Place the screen over the vent opening, ensuring it is centred. Reattach the vent cover on top of the screen. For a more permanent solution, you can use a staple gun to secure the screen in place, keeping a distance of about an inch between each staple. If you're attaching the screen to a brick or stone surface, use caulk to create a strong bond. Apply a bead of caulk about a quarter of an inch from the opening on all sides and press the screen firmly into it.

Seal Any Gaps:

It is crucial to ensure that there are no gaps between the screen and the vent opening. Bugs can enter through even the tiniest of spaces. Follow the instructions on your caulk product to properly seal the screen and fill in any gaps. Allow the caulk to dry completely before turning on your air conditioner.

Maintain and Inspect Regularly:

Keep an eye on your screened vents to ensure they remain intact and effective. Over time, the screen material may need to be replaced, especially if it becomes damaged or torn. Regularly check for any signs of wear and tear and make necessary repairs or replacements.

By following these steps, you can effectively install protective screens around your air conditioner vents, creating a bug-free environment in your home. Remember to also combine this with other bug prevention strategies, such as regular cleaning and maintenance of your AC unit, proper landscaping, and sealing any cracks or gaps in your walls, foundation, and windows.

Keep up with landscaping—remove debris and clutter around the outdoor unit

Keeping up with landscaping and removing debris and clutter from around your outdoor air conditioning unit is crucial for maintaining optimal airflow and performance. Here are some detailed tips to help you achieve that:

Maximise Space for Ventilation:

Provide ample space around your air conditioner to ensure adequate ventilation. The unit releases a significant amount of hot air, and sufficient clearance is necessary for the heat to dissipate effectively. Aim for a clearance of at least 3 to 5 feet on all sides of the unit. This spacing prevents airflow restriction, which can lead to issues such as ice formation on the condenser coils. Proper spacing also ensures easy access for maintenance and repairs.

Choose the Right Plants:

When selecting plants to place around your air conditioner, opt for those that grow upward rather than outward. This growth habit minimises interference with the unit. Evergreens, such as spruce or boxwood, are excellent choices as they retain their leaves or needles year-round, reducing the amount of debris that could accumulate in the unit. Additionally, consider drought-resistant plants, as air conditioners expel a lot of heat, and choose plants that do not attract insects to prevent nest-building near the unit.

Avoid Thorny Plants:

While roses and holly bushes are aesthetically pleasing, their thorns can make maintenance and repairs more challenging. Accessing the equipment for upkeep may become difficult due to the presence of thorns.

Maintain Regularly:

Keep an eye on your plants and trim them as needed to ensure they don't grow too close to the unit. Regularly check your air conditioner for any leaf or branch obstructions, especially if you have nearby trees. It is recommended to have a seasonal summer check-up to ensure your system is functioning optimally.

Use Alternative Landscaping Options:

If you're hesitant to plant directly around the air conditioner, consider potted plants, which offer more flexibility in terms of placement and arrangement. Fencing or a trellis with decorative vines can also discreetly hide the unit without compromising airflow. Creating a gravel garden around the system minimises debris and gives your yard a well-maintained appearance.

Keep the Area Clean:

Grass clippings, leaves, and other yard waste can cause blockages in your air conditioner. Always aim grass clippings away from the unit when mowing, and consider using special mesh screens designed to keep large debris from entering the unit. During the off-season, use a water-repellent cover to protect the unit from falling leaves and strong winds.

Create a rock garden to deter bugs from making nests around the unit

Will planting around my air conditioner draw bugs?

Bugs are attracted to air conditioners for a few reasons. They provide a cool place with a potential source of moisture, and they can be a gateway into your home. The area around your air conditioner should be kept clear of plants, junk, and debris, as these can provide a pathway for bugs to enter.

Rock gardens are a great way to deter bugs from making nests around your air conditioner. Rocks and gravel can deter bugs by disrupting their environment. A rock garden can be aesthetically pleasing and functional, providing an effective barrier against bugs. Here are some steps to create a rock garden around your air conditioner:

• Clear the area: Remove any plants, junk, or debris around your air conditioner. Ensure you have a clean slate to work with, creating a bug-free zone.
• Choose your rocks: Select rocks, gravel, or pebbles that are suitable for your garden. You can use aesthetically pleasing gravel, bricks, large river rocks, or a combination of stones.
• Prepare the base: Create a dry, level base for your rock garden. Consider using a weed barrier, such as landscaping fabric, to prevent weeds from growing through. You can also use a gravel buffer under the rocks to further deter bugs.
• Arrange the rocks: Start placing your rocks or gravel in the prepared area. Be sure to leave some space between rocks for airflow and to create a natural look. You can create different layers and arrangements to add visual interest.
• Add some plants (optional): If desired, you can add some drought-resistant plants or succulents to your rock garden. Just be sure to avoid plants that have a strong fragrance or those that may attract bugs.
• Maintain the garden: Rock gardens are low maintenance but do require some care. Remove any leaves, debris, or weeds that may collect in the garden. You may also need to replenish the gravel or adjust the rocks over time.

By creating a rock garden around your air conditioner, you can deter bugs from making nests while also adding a decorative element to your outdoor space. This, combined with proper air conditioner installation and maintenance, will help keep bugs at bay.
