Prepare Your Central Air Conditioner for Winter

During the winter season we tend to forget all about our Central Air Conditioner, but it’s crucially important that you prepare your air conditioner for the cold weather and snow so that it’s ready to serve you once again in the spring.

The cold winter season means that your home’s furnace will become your close companion once again, but don’t say goodbye to your Central Air Conditioner just yet! If you expect to be using your air conditioner next spring, summer, and for years to come, some maintenance and preparation is necessary to keep your air conditioner running smoothly next spring. The ice and snow around your AC in the winter can do some significant damage to the equipment if the proper precautions are not taken. Let’s get into three ways that you can ensure that your Central Air Conditioner unit is in perfect shape for next spring.

Turn off your AC during the winter season

Your Central Air Conditioner should be powered down for the winter season to prevent any unwanted startups in the spring. If you leave your central AC plugged in during the winter, then when spring rolls around your AC may unexpectedly start up. This may not seem like a huge problem, but if there is any damage or debris in the system then this could escalate problems further and cause greater damage to your air conditioning system. By turning your air conditioner off in the winter you will ensure that it only starts up when you’re ready for it too. Your AC can be turned off via the power outlet located in the small box on the wall of your home.

Should I cover my air conditioner in the winter?

The answer to this question is often debated due to the pros and cons involved with both leaving your Central Air Conditioner covered and uncovered during the winter.

If you choose to cover your air conditioner during the winter season, your AC will be protected from any debris and ice that could possibly penetrate into the system otherwise. Although you have the benefit of added protection from debris, air conditioner covers restrict airflow and can cause for excess moisture in your air conditioning system, while also making your AC system an ideal place for small animals to stay in the winter season. Both of these cons to air conditioner covers can lead to damaging the unit, which leads to system failure or inefficiency when you’re using your Central Air Conditioner next spring and summer.

If you choose to not cover your Central Air Conditioner unit during the winter then you should not face the problems of excess moisture and small animals hibernating in the system. The downside to not covering is that you are not protected from any debris that can enter the system due to the weather conditions of the winter season.

The choice of whether to cover or not is yours. A good middle ground between these two options is to partially cover your air conditioner by only covering the top. By doing this you are protecting the top of the AC unit while allowing for proper air flow.

Schedule Air Conditioner Maintenace in the Fall or Winter Season

It may seem odd to schedule Central Air Conditioner maintenance at a time when you aren’t even using the equipment, but this will actually get rid off any potential problems that you may experience in the spring season. Scheduling air conditioner maintenance from a trained HVAC technician will get rid of any dirt that could be in the system which would be trapping moisture similarly to an AC cover. Air conditioner service will also fix any other problems you may be having and ensures that your system is running smoothly for the summer.


By following these three tips we can assure you that your Central Air Conditioner unit will be ready for the winter season.
