Customer Reviews
“This cover was just put on for the first time and it’s amazing! Fit almost perfectly but not to worry as it has these draw strings that you can lock to tighten it up. Also has a slit for the piping with a locking tab for the flaps. For the price paid, this is an awesome product.” – Verified Buyer

Complete Buying Guide for Carrier Air Conditioner Covers
Essential Factors We Consider
When choosing a carrier air conditioner cover, size is the most critical factor—measure your unit’s width, depth, and height before buying. Material matters too: 600D polyester offers the best balance of durability and weather resistance, while mesh covers are ideal for airflow but don’t block rain. Look for features like air vents, secure closures (drawstrings or buckles), and UV protection. Finally, consider your climate: full covers work best in snowy or rainy regions, while mesh tops are better for leafy or pest-prone areas.
Budget Planning
Prices range from under $20 for basic mesh covers to over $50 for heavy-duty waterproof models. Our Best Budget pick (Ravenna) proves you don’t need to overspend for quality, while premium options like our Editor’s Choice offer extra peace of mind for larger investments. Set a budget based on your unit size and local weather risks.
Final Thoughts
A good cover is a small investment that can save you hundreds in repairs or early replacements. Whether you go full-coverage or opt for a breathable mesh top, protecting your Carrier AC unit is one of the smartest home maintenance decisions you can make.
Frequently Asked Questions
Q: Should I cover my Carrier air conditioner in the winter?
A: Yes—but only with a breathable, waterproof cover that allows ventilation. Avoid plastic tarps, which trap moisture and cause rust. Full covers are best for snowy climates, while mesh tops work well in milder areas.
Q: Can I leave a mesh cover on while the AC is running?
A: Absolutely! Mesh covers are designed for year-round use and won’t restrict airflow. They’re perfect for keeping leaves and animals out without shutting down your system.
Q: How do I know what size cover to buy?
A: Measure your outdoor unit’s width, depth, and height. Choose a cover that matches or slightly exceeds these dimensions. Most product descriptions include exact fit ranges.
Q: Will a cover void my Carrier warranty?
A: No—using a proper AC cover does not void your warranty. In fact, many manufacturers recommend seasonal protection to maintain efficiency and longevity.
Q: How often should I replace my air conditioner cover?
A: High-quality covers last 3–5 years with proper care. Replace sooner if you notice tears, fading, or loss of waterproofing.
