Is Your Outside HVAC Unit Ready for the Snow?

Winterizing your outdoor A/C, or HVAC, unit protects it from rust damage caused by snow and ice. By investing in a few important precautions, you will protect your expensive hardware and ensure that all is in working order when you need it the most.

  1. Before the weather drops to freezing temperatures, you should take your garden hose and spray off any debris that has accumulated over the summer—bird droppings, dead bugs, leaves and grass—and then allow the unit to air dry before moving on to the next step.
  2. Protect exposed pipes with foam covers, using duct tape to secure the covers through the coming snow storms.
  3. Consult with an expert before covering your unit for the duration of the winter. Sometimes, depending on the unit, it can do more harm than good. It’s a good idea however to cover your unit temporarily if the weather forecast predicts a blizzard or hailstorm. Any waterproof material will do. There may be custom covers available for your unit, but lacking one of those, you can use any appropriately sized piece of vinyl or plastic. You’ll need to secure the cover with waterproof rope or bungee cord.
  4. Make sure the unit is turned off. You don’t want to risk it automatically turning on during an unseasonably warm winter If it does, there’s a chance water can enter the unit to later freeze and cause problems.
  5. Monitor the state of your unit about weekly to make sure there’s not too much accumulation of snow and debris. You’d be surprised how the weight can added up and you don’t the surprise of discovering damage to your unit in the summer.
