Should I Put a Tarp Over My Air Conditioner? Protecting Your Investment
The question is a common one, but the answer is generally no: Should I put a tarp over my air conditioner? Doing so can actually do more harm than good, potentially trapping moisture and damaging the unit.
Understanding Air Conditioner Vulnerability
Air conditioners, especially the outdoor condenser units, are built to withstand the elements. They are designed to be exposed to rain, snow, sun, and wind. However, that doesn’t mean they are impervious to damage. Understanding their vulnerabilities is key to proper maintenance.
- Debris Accumulation: Leaves, twigs, dirt, and other debris can accumulate inside the unit, reducing airflow and efficiency.
- Corrosion: Exposure to moisture and salt air can lead to corrosion of the metal components.
- Ice Buildup: In cold climates, ice can form on the coils, potentially damaging them.
- Animal Intrusion: Small animals can sometimes seek shelter inside the unit, causing damage to wiring or other components.
The Potential Problems with Tarps
While the intention behind using a tarp is often to protect the air conditioner, it can create a host of problems:
- Moisture Trapping: Tarps can trap moisture against the unit, leading to rust and corrosion. This is particularly problematic in humid climates.
- Restricted Airflow: A tarp can restrict airflow around the unit, which can cause overheating when the air conditioner is in operation, even during mild winter days.
- Animal Habitat: The sheltered space under the tarp can become an attractive habitat for rodents and insects.
- Accelerated Deterioration: By trapping moisture and promoting corrosion, a tarp can actually accelerate the deterioration of the unit.
Better Alternatives for Protecting Your Air Conditioner
Instead of using a tarp, consider these safer and more effective ways to protect your air conditioner:
- Regular Cleaning: Regularly remove leaves, twigs, and other debris from around the unit. Use a garden hose with a gentle spray nozzle to clean the coils.
- Professional Maintenance: Schedule annual maintenance with a qualified HVAC technician. They can inspect the unit, clean the coils, and identify any potential problems.
- Protective Covers (Designed for AC Units): Use a cover specifically designed for air conditioners. These covers are typically made of breathable materials that allow air to circulate, preventing moisture buildup. These covers only cover the top of the unit, allowing for airflow around the sides.
- Landscaping: Trim shrubs and trees around the unit to improve airflow and prevent debris from falling into it.
Step-by-Step Guide to Cleaning Your AC Unit
Cleaning your AC unit is a crucial step in protecting your investment and maintaining its efficiency.
- Turn off the Power: Disconnect the power to the air conditioner at the breaker box to prevent electric shock.
- Remove Debris: Clear away any leaves, twigs, or other debris from around the unit.
- Clean the Coils: Use a garden hose with a gentle spray nozzle to clean the coils. Spray from the inside out to remove dirt and debris.
- Straighten Bent Fins: If any of the fins on the coils are bent, use a fin comb to straighten them.
- Reassemble and Power On: Once the unit is clean and dry, reassemble any parts that were removed and restore power to the air conditioner.
Choosing the Right Protective Cover
If you choose to use a protective cover, make sure it is the right type. Avoid using solid tarps that completely enclose the unit. Look for covers made of breathable materials that allow air to circulate. The ideal cover protects the top of the unit while still allowing airflow around the sides.
Here’s a comparison of different types of covers:
| Cover Type | Material | Breathability | Protection Level | Pros | Cons |
|---|---|---|---|---|---|
| ———————– | —————— | ————- | —————– | —————————————————————————- | —————————————————————————– |
| Solid Tarp | Vinyl/Polyethylene | Low | High | Inexpensive | Traps moisture, restricts airflow, can damage unit |
| Breathable AC Cover | Polyester/Canvas | High | Moderate | Allows airflow, prevents moisture buildup, protects from debris | More expensive than tarps, may not provide complete protection from the elements |
| Custom Fitted AC Cover | Varies | Varies | High | Designed specifically for the unit, provides good protection and airflow | Most expensive option |
Common Mistakes to Avoid
- Using a Solid Tarp: As mentioned earlier, using a solid tarp is a common mistake that can do more harm than good.
- Enclosing the Entire Unit: Avoid covering the entire unit, as this can restrict airflow.
- Ignoring Regular Maintenance: Neglecting regular cleaning and maintenance can shorten the lifespan of your air conditioner.
- Forgetting to Remove the Cover Before Use: Always remove any covers before turning on the air conditioner.
Now, let’s explore some frequently asked questions to deepen your understanding.
What are some other ways to protect my air conditioner from severe weather?
Besides the methods already discussed, consider these additional steps to safeguard your AC during extreme weather events. During hurricanes or severe storms, consider wrapping the unit with straps to prevent it from being dislodged. However, remember to remove these straps before running the AC. Secure any loose objects around the unit that could be blown into it.
How often should I clean my air conditioner?
Ideally, you should clean your air conditioner at least twice a year: once in the spring before you start using it and once in the fall after you’ve finished using it. If you live in an area with a lot of dust or pollen, you may need to clean it more frequently.
Is it okay to cover my air conditioner in the winter?
It depends. If you are using a breathable AC cover that only protects the top of the unit, it’s generally okay to cover it in the winter. However, avoid using a solid tarp that completely encloses the unit.
What happens if my air conditioner gets covered in snow and ice?
If your air conditioner gets covered in snow and ice, it’s generally best to leave it alone. Do not try to chip away at the ice, as this could damage the coils. The ice will eventually melt on its own.
Can I use a pressure washer to clean my air conditioner?
While a pressure washer can be effective for cleaning some outdoor equipment, it is not recommended for cleaning air conditioners. The high pressure can damage the delicate fins on the coils. Use a garden hose with a gentle spray nozzle instead.
Should I hire a professional to clean my air conditioner?
While you can clean your air conditioner yourself, it’s always a good idea to hire a professional HVAC technician for annual maintenance. They can perform a more thorough cleaning, inspect the unit for any potential problems, and make any necessary repairs.
Does covering my air conditioner save energy?
No, covering your air conditioner will not save energy. The primary purpose of covering your air conditioner is to protect it from the elements when it is not in use.
What type of material is best for an AC cover?
The best material for an AC cover is a breathable fabric like polyester or canvas. These materials allow air to circulate, preventing moisture buildup.
How do I prevent animals from nesting inside my air conditioner?
To prevent animals from nesting inside your air conditioner, keep the area around the unit clean and free of debris. You can also install a wire mesh screen around the unit to prevent animals from entering.
Does covering my air conditioner void the warranty?
It’s unlikely that using a breathable AC cover will void your warranty. However, using a solid tarp that damages the unit could potentially void the warranty. Always check the terms of your warranty for specific details.
How do I know if my air conditioner needs repair?
Signs that your air conditioner needs repair include reduced cooling performance, unusual noises, leaking refrigerant, and increased energy bills. If you notice any of these signs, contact a qualified HVAC technician.
What is the lifespan of an air conditioner?
The average lifespan of an air conditioner is 10-15 years. However, with proper maintenance, you can extend the lifespan of your air conditioner.
