Winterize your HVAC unit to prevent damage during cold New England weather.

Across New England leaves are beginning to change and temperatures are getting cooler. In between apple picking, leaf peeping and cider sipping, it’s important to make sure your outdoor A/C unit is ready for winter weather.  While your air conditioner was designed to be outdoors, and won’t malfunction when exposed to rain or snow, winterizing the unit can prevent damage caused by harsh winter conditions and extend the service life of your A/C.

As a reminder, taking precautions based on manufacturer recommendations is the best way to remain covered by home warranty. Today we will look at five recommendations for winterizing your HVAC:

5 tips for homeowners winterizing air conditioning condenser unit

  1. Shut Off Unit

Locate the AC electric disconnect switch near your unit and flip the switch to “off.” This prevents your air conditioner from turning on during warm fall days. While it can feel refreshing to have the A/C run for a day in the off-season, water can get into the coils and freeze once temperatures drop again, causing rust and corrosion within the unit.

  1. Clean A/C Unit

Pick a warm day so the unit can dry completely. Wash away dirt, bugs and bird droppings from the outside casing. Remove leaves, sticks and other debris from around the bottom of the unit. This can also prevent small animals from nesting in your unit as well.

  1. Insulate Exposed Pipes

Make sure exposed pipes are covered with foam pipe covers to avoid frozen and broken lines. You can simply slip the insulated covers over exposed pipes and duct tape it together.

Checking on your HVAC equipment throughout the year extends the life of your system.

  1. Check on Outdoor Unit throughout Winter

Throughout the winter, make sure to do a visual inspection of your condenser to make sure there isn’t any debris or nests inside the unit.
