Is Your AC Failing? 5 Warning Signs to Watch For in Littleton, CO

Do Not Cover Your Heat Pump
As temperatures drop, many homeowners feel the urge to “tuck in” their outdoor AC or heat pump for winter. Tarps, covers, and bungee cords often come out as a way to protect the unit from snow and cold. It’s a well-intended habit, but in most cases, fully covering your condenser actually does more harm than good.
Built to Be Outside
Outdoor HVAC equipment is designed to live outside year-round. Rain, snow, ice, and wind are all part of what these systems are built to handle. What they are not designed for is trapped moisture and limited airflow. When a unit is wrapped tightly, condensation can build up underneath the cover, leading to corrosion, rust, and premature wear on critical components.
Covers Can Invite Critters
Another common issue with full covers is that they create the perfect shelter for rodents and small animals. Warm, protected spaces attract squirrels, mice, and other critters looking for a winter home. Once inside, they often chew wiring and insulation, turning a simple spring startup into an unexpected repair visit.
If You Must Cover, Go Top-Only
If you’re concerned about falling debris or heavy snow, a top-only cover can be a reasonable compromise. Think of it as a lid, not a sleeping bag. Leaving the sides open allows airflow, prevents moisture buildup, and discourages animals from nesting inside. When in doubt, leaving the unit uncovered is usually the safest option for long-term performance and reliability.
