With winter right around the corner, the last thing you’re probably thinking about is your air conditioner. While that makes sense, your AC needs some attention before spring. In fact, not properly winterizing your AC unit is one of the most common mistakes homeowners make. Let’s walk through what you need to know to protect your air conditioner.

Why Winterizing Matters

Your outdoor AC unit faces harsh conditions during the winter. Snow, ice and many types of debris all take their toll on sensitive internal components. Without proper protection, moisture can get inside and freeze, potentially damaging the fins, coils and compressor. A little preparation now ensures your AC will be ready to go when warm weather returns.

Clean Your Unit First

Before the coldest months of winter arrive, give your AC unit a thorough cleaning. Turn off the power at the breaker box, and clear any twigs, leaves or debris from around and inside the unit. Use your garden hose to gently spray the fins and coils, removing any dirt and buildup. This will prevent moisture from sitting against dirty components all winter long.

Inspect for Internal Damage

While cleaning, look for bent fins, loose parts and other signs of wear and tear. Having a professional straighten bent fins now ensures better airflow when you start up the unit again in spring. If you find signs of damage, note it so that you can have it repaired before it gets hit again.

The Great Cover Debate

Here’s where opinions differ among HVAC professionals. Some HVAC technicians recommend covering only the top of your unit to prevent debris from falling in while leaving the sides exposed. Others suggest using a breathable full cover.

However, one thing that everyone agrees on is this: Never use a plastic tarp or a completely sealed cover. Trapping moisture inside the unit creates the perfect environment for rust and mold. If you use a cover, choose one specifically designed for AC units with proper ventilation.

Protect Your Indoor Components Too

Don’t forget about your indoor system. If you have a central air system, locate the condensate drain line and make sure it’s clear of debris. This will prevent water from sitting in the line all winter. You can also consider turning off the circuit breaker dedicated to the AC to prevent accidental activation during warmer winter days.

Mark Your Calendar

Set a reminder in early spring to reverse these winterization steps. You’ll want to remove covers, turn the power back on and let the system sit for at least 24 hours before first use. This will allow the compressor oil to warm up properly.

Taking an hour or two now to winterize your air conditioner properly means you’ll avoid unexpected surprises when summer arrives.
