Skip the AC cover (mostly)
Annual · typically November
Why it matters
Every fall the covers appear at the big-box stores, and every spring the service techs find what they did: coils sweated under vinyl all winter, rust where the moisture sat, and mouse nests in the wiring of the warmest sheltered box in the yard. Your condenser is engineered for rain, snow, and sun — the manufacturers don't require covering, and most explicitly advise against full wraps.
What skipping it costs
$0–$600
This is the rare card where the neglect IS the right move. The damage runs the other way: full covers trap condensation against the coil all winter and invite mice to move in and chew wiring — a $300–$600 spring repair sold to you as protection.
Two ways to get it done
Do it yourself
You'll need: Optional: a piece of plywood and a brick — that's the whole product.
The whole task, ten minutes in November:
- Look up. Anything above the unit that drops ice, water, or branches in winter? If no — you're done. Genuinely done.
- If yes: lay a rigid lid across the top with an inch or two of overhang, weighted with a brick. Sides stay open. Air moves, moisture leaves, mice keep looking.
- Clear leaves off the top grille while you're standing there.
- If your unit regularly ends up buried by snow sliding off the roof, the durable fix is a small awning or relocating the unit — worth pricing in spring, not December.
Hire it out
$40–$80National fair range — local labor moves this number.
There's nothing here to hire — which is the point of the card. If you want the drip-line lid built nicely instead of plywood-and-brick, any handyman will knock one together for $40–$80.
Save the cover money. Put it toward the spring coil rinse, which — unlike the cover — actually extends the unit's life.
Ask the tech
- If you're recommending a cover, what specifically is falling on this unit?
Red flags you're being upsold
- Custom-fitted full covers sold at $80–$200 'to protect your investment.' Full covers hold moisture against the coil and make a five-star rodent condo out of your condenser.
- Any cover pitch for a heat pump, ever — it runs all winter, and covering a running unit can wreck it.
The call
Skip the cover. Your AC is built to sit outside in the weather — that's its whole job. The one exception: a flat board on top if the unit sits under a roof drip line or falling icicles.
