Why Covering Your AC Unit Could Be a Mistake
As the winter chill sets in, you might feel the urge to cover your air conditioning unit to protect it from the elements. However, experts recommend against this common practice for several important reasons that could keep your unit running smoothly for years to come.
The Risks of Covering Your AC Unit
When you cover your AC unit, moisture can become trapped inside. This damp environment promotes mold growth and can lead to rust and premature corrosion of the unit’s internal parts. Sean Hogan, an HVAC expert, argues that modern air conditioners are designed to withstand weather, allowing ice and water to drain naturally.
Additionally, tightly covering the unit can create an inviting shelter for small animals like mice and squirrels. These critters can chew on electrical wires, obstruct drains, and even leave behind droppings, which can cause internal damage and unpleasant odors when you start your AC up in the spring.
Expert Tips for Winter Prep: Keeping It Clean and Efficient
Instead of covering your AC unit, focus on simple maintenance steps to ensure it remains in peak condition. Here are some tips from HVAC experts:
- Clean the Unit: Remove leaves and debris from around the unit and inside the fins. This prevents moisture buildup and helps maintain airflow.
- Examine Drainage: Ensure that water can drain freely from the unit. A clogged or frozen drain can cause excessive water accumulation.
- Trim Surrounding Vegetation: Make sure to clear at least two feet of space around your air conditioning unit. This allows for proper airflow and helps prevent leaves and debris from contaminating the unit.
- Schedule Regular Inspections: Consult a qualified HVAC professional to conduct an annual checkup. This can help identify issues before they become major problems.
- Consider Limited Covers: If you're really concerned about ice accumulation, opt for a “top-only” cover that allows for ventilation while protecting crucial components from snow.
What Happens if You Forget?
It’s easy to forget a cover is on during an unexpected warm spell. Homeowners who accidentally turn on their AC while it’s still covered may find that they have damaged the unit due to restricted airflow, which can lead to costly repairs. Randall Boutte, an HVAC technician, emphasizes the importance of routine maintenance and checking for obstructions before turning the unit on.
Wrapping Up: The Right Way to Care for Your AC Unit
While covering your AC unit might seem beneficial, it often does more harm than good, including trapped moisture, rust, and the risk of pest damage. With proper maintenance and attention, your air conditioning unit can survive the winter in great shape and be ready to cool your home when you need it again. Remember, when in doubt, consulting with a professional can help preserve your investment!
