I was told by an HVAC technician that an outside air-conditioner condenser should be covered in the winter, when it’s not in use, to protect it from snow getting inside. He recommended covering the unit with a piece of plywood weighed down with a rock so the sides would be left open to prevent condensation from forming inside. I tried this, but soon found that a heavy wind would get under the plywood and blow it off. I also tried a small tarp tied to the condenser with wire ties, but the tarp would get torn up before the winter was over. The drawing at left shows my solution. A plastic saucer sled and three bungee cords work perfectly as a weatherproof cover. I drilled three holes equally spaced on the circumference of the saucer sled and attached it to the louvres on the sides of the condenser. The saucer sled has lasted for years.
