Why You Should Use an Evaporative Cooler Cover in the Winter (and How to Size It)

When winter settles in and temperatures drop, your evaporative cooler is ready for a well-deserved break. But before you leave it idle for the season, it’s important to protect it from the elements. Using a high-quality evaporative cooler cover is one of the simplest and most effective ways to extend the life of your cooler, prevent costly repairs, and keep your home more comfortable during colder months.

The Benefits of Using an Evaporative Cooler Cover

1. Prevents Rust and Corrosion

Winter moisture, snow, and rain can enter an uncovered cooler and lead to rust, corrosion, and premature wear. A properly fitted evaporative cooler cover keeps water out and significantly reduces long-term damage.

2. Blocks Cold Drafts From Entering Your Home

An unused cooler can act like a chimney, allowing cold outside air to funnel directly into your living space. A winter cover creates an insulating barrier, improving energy efficiency and helping maintain a warmer, more consistent indoor temperature.

3. Keeps Out Dirt, Debris, and Pests

Leaving a cooler uncovered invites dust, leaves, and even small animals to take up residence inside. A cover keeps your unit clean during winter, so it’s ready to run smoothly when spring arrives.

4. Extends the Lifespan of Your Cooler

A small investment in a cover can save you money over time by reducing wear and preventing unnecessary repairs or component replacements.

How to Choose the Right Size Evaporative Cooler Cover

Selecting the correct size is crucial for a secure fit and effective protection. Fortunately, sizing a cooler cover is straightforward when you know what to measure.

Step 1: Measure Your Cooler

Measure the width, depth, and height of your evaporative cooler. Use the outside dimensions of the cabinet, not the internal ones.

Step 2: Compare Your Measurements to the Size Chart

On our Cooler Cover product pages, you’ll find sizing charts that match your dimensions to the correct cover size. Because sizing is standardized, most people can find the right fit quickly.

Step 3: Understand How Covers Are Designed

Cooler covers are intentionally made slightly larger than the listed size. This extra room accommodates:

• Small electrical fittings
• Protruding hardware
• Pad frame variations
• The natural tolerance needed for easy installation

This built-in allowance ensures the cover fits securely without being tight or difficult to remove.

Step 4: When in Doubt, Size Up

If your cooler is between two sizes, choosing the larger one usually provides the best fit thanks to the adjustable drawcord or straps included with most covers.

Tips for Installing Your Evaporative Cooler Cover

• Drain the cooler and disconnect the water line before covering.
• Clean the exterior to prevent debris from trapping moisture under the cover.
• Secure all straps or drawcords so the cover stays tight in windy conditions.
• Consider an interior vent cover for added protection against drafts.
