Why Put a Screen Around an AC Unit?
Here are some of the top reasons for adding a screen around an exterior air conditioner:
Protect the Unit
A screen can help protect an outdoor AC unit from damage. Debris like leaves, sticks, and lawn clippings can get sucked into the unit while it’s running and cause clogged air filters or other problems. Pests like birds and rodents may try to nest or chew on wiring. A screen provides a barrier to help keep these hazards away.
Improve Efficiency
A screen around an air conditioner can improve its efficiency in a couple ways. First, it prevents debris buildup on the coils and in other components, allowing optimal air flow. Second, the screen creates a small “dead air” zone around the unit, insulating it slightly from the external environment. This helps reduce strain on the AC.
Reduce Noise
The whirring, humming, and other noises emitting from an AC compressor and fan can be annoying. Installing a screen around the unit can dampen the noise. This is especially helpful if the unit is near windows or patios where people spend time.
Aesthetics
Some people add a screen simply for appearance purposes. An ugly metal box isn’t the most attractive feature on the side of a house. A nicely designed screen can make the unit less of an eyesore and blend in better with the home’s landscaping and architecture.
What to Consider Before Adding a Screen
While screens provide benefits, they also come with some drawbacks and considerations you should keep in mind:
Air Flow Requirements
Impeding air flow too much around an AC unit can cause it to overheat and lead to problems. There needs to be adequate clearance between a screen and the sides/top of the unit. Generally there should be at least a few inches gap.
Access to the Unit
You’ll still need periodic access to the air conditioner for maintenance like cleaning. The screen setup needs to include an easy way to open or remove sections to reach the unit.
Moisture Drainage
Outdoor AC units produce a lot of condensation that drips from the coils. This moisture needs proper drainage so it doesn’t pool under or near the unit. The ground should slope away and the screen must have adequate clearance.
Appearance
While a screen can improve appearance, a poorly designed one can make it worse. Carefully choose materials and colors that complement your home rather than clashing.
HOA Rules
If you live in a homeowner’s association community, make sure screens are allowed. Even if allowed, there are likely restrictions on colors, materials, size, etc.
Screen Materials
Screens for AC units are typically made from one of these materials:
Plastic
Plastic, including vinyl and PVC, is lightweight, weather-resistant, and easy to work with. Plastic screens snap together and are semi-transparent to allow some air flow. They’re a lower cost option compared to metal and wood screens.
Metal
Aluminum, galvanized steel, and other metals offer durability and customizability though at a higher price. Metal screens come in various perforated patterns to allow airflow while concealing the unit. Wrought iron screens provide an elegant look.
Wood
Stained cedar, redwood, and pressure treated pine are common wood choices. Wood screens provide privacy and a classic, natural aesthetic. They require more maintenance than plastic and metal though.
Polyester Fabric
Polyester is used to make screens that are opaque or semi-transparent mesh “curtains”. These are inexpensive but less durable than solid panels. They’re easy to install around an AC unit.
Screen Designs and Installation
Here are some common options for the design and setup of an AC unit screen:
Partial vs Full Enclosure
A partial screen consists of panels around just the sides or back of the unit while a full enclosure surrounds the entire perimeter. Full screens provide more aesthetics and noise reduction benefits.
Standing Screens
Free-standing screens are installed a short distance away from the AC unit on stakes or a frame. These allow maximum airflow and accessibility to the unit.
Attached Screens
For a seamless look, screens can be securely mounted directly to the side of the house around the unit. Allow at least a few inches space between the screen and AC edges.
Lattice
A lattice screen made from wood or plastic is an open-air option that still obscures the unit view. Lattice is less effective for noise reduction.
Landscaping Integrated
Some screens are designed as part of gardens and landscaping. For example, you could do rows of tall decorative grasses or bamboo to conceal the AC naturally.
Roofed Enclosures
A roofed screen creates a shed-like structure around the unit to protect from falling debris and improve aesthetics. Just be sure not to block airflow under the eaves.
Sliding Panels
Another option is to install screens as individual sliding panels. This allows you to easily open up sections when needed to access the AC unit.
Best Practices for Installation
Follow these best practices when installing a screen for your outdoor AC unit:
– Measure carefully to allow adequate clearance – at least a few inches – between the AC and screen on all sides. This enables sufficient airflow.
– Anchor the structure securely into the ground or onto your home. Screens are prone to being moved by weather if not properly secured.
– Funnel drainage away from the unit area so moisture doesn’t pool under the screen. Consider using gravel and grading the ground.
– Use rust resistant hardware and treatments on any metal components to prevent corrosion over time.
– If attaching directly to the home, use non-invasive methods like tapcons instead of drilling into siding or the structure.
– For standing screens, make sure the frame is level and plumb. Check that panels are oriented correctly before fastening.
– Follow all included manufacturer instructions carefully during assembly, especially regarding spacing and clearance.
– Screen off access doors so you can easily reach the AC unit, electrical panel, etc. for maintenance.
– Confirm the screen meets any HOA requirements and building codes for your area.
DIY vs Professional Installation
Installing an AC unit screen is a project a handy homeowner can tackle as long as some simple precautions are taken, especially regarding proper clearance. But for more complex designs and enclosure structures, having a professional take care of the installation is a safer bet. Things pros can handle that may prove difficult for DIYers include:
Precisely Measuring
The technician will use care to measure the required spacing down to the inch and ensure your particular AC unit model has room to breathe.
Accounting for Condensation
A pro will properly accommodate moisture runoff and drainage around the newly screened area.
Leveling and Securing
Precisely anchoring a sturdy frame and verifying panels are level may take an extra set of experienced hands.
Working at Heights Safely
Attaching a roofed enclosure or screens high on walls is best left to someone used to working at elevation.
Installing on Siding
For attached screens, the pro has techniques to safely mount to exterior siding without damaging it.
Permit Requirements
In some cases, permits are needed for AC unit screens based on the size and extent of the structure. A contractor will know the requirements and handle any needed paperwork.
Cost to Add an AC Screen
The cost to add a screen around an outdoor air conditioner depends on the type of screen material and complexity of the design:
Plastic Screens
– Partial plastic panel screens: $150 – $400
– Full plastic enclosure: $400 – $800
Wood Screens
– Partial wood fence: $400 – $700
– Full wood enclosure: $800 – $1500
Metal Screens
– Decorative standing metal screen: $500 – $900
– Full custom metal enclosure: $1000 – $2000
Professional Installation Fees
Expect to pay $50 – $100 per hour for labor and setup if hiring a contractor. More complex designs could run $1500 or more for installation.
Alternatives to AC Unit Screens
If you decide not to add a screen around your air conditioner, here are a couple alternate ways to achieve some of the same benefits:
Strategic Landscaping
Positioning plants, bushes, flowers or other greenery around the unit can help block views and noise while blending into your outdoor decor.
Window Awnings
If the AC noise bothers you, install exterior window awnings to help deflect the sound away from areas where you spend time.
Window Films
Installing solar window films improves indoor insulation. This helps reduce noise penetration through windows and lessens the cooling load and strain on the AC unit.
Equipment Maintenance
Keeping your AC unit properly maintained improves efficiency and reduces noise from failing components. Change filters, clean coils, and repair issues promptly.
Conclusion
Adding a screen or enclosure around your outdoor air conditioning unit is a project worth considering to protect the equipment, reduce noise, and improve appearance. Work with qualified pros when needed, follow best installation practices, and choose screen materials carefully. With the right design approach, you can discretely integrate the AC into your home’s architecture and landscaping.
