Why You Should Not Fully Cover Your AC Unit
Find out if covering your air conditioner for winter in Springfield, MO is a good idea. Learn expert tips from SS&B Heating & Cooling.
For over 55 years, SS&B Heating & Cooling has been the trusted name in Springfield, Missouri, for honest HVAC service. Since 1969, we’ve helped thousands of local families stay warm in winter and cool in summer. As the snow starts to fly across the Ozarks, we get one question more than any other: “Should I cover my air conditioner for winter?”
The answer? No – and here’s the full story. This isn’t just our opinion — it’s backed by decades of hands-on experience and what today’s top manufacturers recommend. Let’s walk through everything you need to know to protect your AC (and your wallet) this winter.
What Your AC Unit Really Does in Winter
Your outdoor condenser rests during the cold months. Central air systems share the same blower and ducts as your furnace, but the AC coil outside doesn’t run once temperatures fall below 60°F.
That’s why it doesn’t need a heavy cover—it’s built to handle Missouri’s weather. The casing, fan blades, and internal components are designed to resist rain, sleet, and snow. In fact, the biggest threat isn’t cold—it’s lack of airflow if you seal it too tightly.
The Right Way to Protect It
If you want to show your AC some love before winter, here’s how SS&B recommends preparing:
- Shut off power at the outdoor disconnect box.
- Clean away debris like leaves, grass, and acorns.
- Cover only the fan top with a vented mesh shield—keep sides open.
- Inspect your furnace filter; airflow matters for winter comfort.
- Schedule your annual furnace tune-up so both systems are ready for Missouri’s unpredictable cold snaps.
These simple steps help your system breathe and prevent corrosion or electrical damage during winter downtime.
What About Heat Pumps?
If you have a heat pump, never cover it. Heat pumps run year-round, even in freezing weather, extracting warmth from outdoor air. A cover will block that airflow and make the system work overtime.
If you’re not sure whether you have a standard AC or a heat pump, call SS&B—we’ll help you identify your setup and make sure it’s operating safely for the season.
Quick Winter Tips from SS&B
- Keep snow and ice at least 18 inches away from your outdoor unit.
- Don’t store items like shovels, decorations, or trash bins against it.
- Inspect once a month for buildup or critters.
- If you hear unusual noises when the system first kicks on in spring, call us right away—it might be an easy fix before it turns costly.
- Book your spring AC tune-up early to avoid the rush once warm weather returns.
