How Do I Take Care of My AC Unit During Winter?

Imagine this: the leaves have all fallen, and the weather has never been chillier. Whether you go to the reference or not, you need to be prepared: winter can be detrimental for your outdoor AC unit. 

In order to maintain a comfortable temperature in your dwelling year-roof, it’s advisable to have a solid air conditioning maintenance plan in place. As the winter sets in and the temperature drops, it’s especially important to take some extra safety measures with the exterior unit, which is directly exposed to the weather conditions. 

Similar to servicing your furnace regularly, it’s in your best interest to add winter aircon maintenance to your to-do list. By doing so, you will dodge unexpected damage to the unit caused by low temperatures and water. More often than not, homeowners are advised to include these steps in their AC maintenance scheme before and during the winter months: 

Prepare Your AC 1

Switch the Unit Off 

Prior to any maintenance task, it’s important to turn off your air conditioning’s power supply. This way, the AC won’t pose an electrocution danger while you’re cleaning or inspecting it. Also, you want to be sure the AC doesn’t accidentally turn on on an unusually warm day. Your AC’s power control is located in a box that’s attached to the exterior wall of your house. You will see a box made of metal cover or plastic inside which lays the flip. 

Clean Your AC Unit 

 The air conditioning unit and the area around it accumulate leaves, dirt, bird excrement, and other types of debris. Take a broom and try cleaning as much of the grime as possible. Next, wash it down using a hose to remove the rest of the dirt. Before proceeding with a much-needed maintenance task, you will need to let the unit dry completely. Cleaning will protect your air conditioning from breakdowns caused by clogging. Choose a sunny or not too windy day for cleaning as the wind may blow the debris inside the unit. 

Inspect Your AC Unit 

Your AC should be diligently checked next. Pay attention to its exterior; look for any signs of cracks, corrosion, and other issues. Also, examine the seals to determine the condition they’re in. If something’s off, don’t hesitate to contact your contractor for an expert inspection of a problem that may be too dangerous or complicated. Reliable AC technicians will identify the core of the problem and prevent further deterioration of your unit. 

Insulate Your AC Unit 

Prevent harsh winter conditions from damaging your air conditioning by insulating and covering it. Strong wind can lead to the accumulation of debris that could impair the function of your AC unit. Even more, water could seep into the unit and freeze inside, causing a fault with the condenser fins. 

Fortunately, you can reduce your exterior unit’s contact with the harsh weather elements in a very simple way by applying a cover during the winter. Note that this cover should be made of breathable material and be able to tolerate the weather and keep the dirt out. Your AC’s pipers and wiring, too, need to be protected with duct tape and pipe insulation. They’re less exposed to freeze and cracks this way.
