Running Your AC in Your Caravan During Winter

Nowadays nearly every home has an air conditioner, as does every caravan. Yet with winter approaching, it is nearly time to wait until next summer. Or not? In this article, we discuss how you can run your AC in winter and answer all your concerns!

While the majority of us believe that an air conditioner only works to cool, that is not entirely true. Modern air conditioners can regulate all seasons. It works by reversing its function, allowing the AC to run during winters. 

Although caravan air conditioners work during winter, there still are safeguards that need to be kept in mind. 

Can I Run My AC in my Caravan During Winter?

The answer is yes! In the case of a reversible air conditioner or ductless heat pump, it makes sense to use the air conditioner year-round. 

Even if your air conditioner is not reversible, you may still find some use during winters. If your room is getting too stuffy, you could turn on your air conditioner in fan mode and make the room comfortable.

When Does It Get Too Cold for an Air Conditioner?

Air conditioners have a minimum threshold for their operation. Whatever the air conditioner brand or model or type, there is a minimum limit for the operating temperatures.

Running the air conditioner below the minimum temperatures can result in damage to the appliance, such as:

• Freezing of refrigerant coils

• Thickening of lubricant

• Damage to moving parts and bearings

How to Run During Winter?

With furnaces and ducted systems being expensive, it is smart to look for alternatives that are just as effective in heating. Instead of having a separate heating appliance, what if you can do both heating and cooling with one?

That is precisely what a reversible mini-split heat pump does. You can use the same appliance within the year, to keep you cool in the summers and warm in the winters. Besides a mini-split, there are many different types of heat pumps available on the market too.

How air conditioners operate is by transferring heat from a hot environment (indoors) to a cooler one (outdoors). This is satisfactory during summertime. Yet in the winter months, you want to get the heat from the outdoors and transfer it indoors. 

To do this, a reversing valve is used in heat pumps, and heating functionality is achieved.

Freeze Protection Mode 

Freeze protection is provided by some air conditioners and is useful for places that feel extreme cold. The AC operates at a low power setting where warm air is continuously introduced into the room. This feature stops the room temperature from falling below freezing or near freezing point. This minimises damage to sensitive electronic equipment, water pipes, or paintings at a low cost.

Will Running AC in Cold Weather Damage It?

There are multiple factors at play, and running AC in winter is not without risks. With moderately cold temperatures, an air conditioner is able to run in any mode. But with temperatures below 15 degrees Celsius, it can be risky, such as:

Loss of Lubrication

Compressors are important and need to be in good shape. Lubricants help smooth the compressor to function without fault. In winter, it can thicken and not function, leaving it prone to damage. 

Low Ambient Temperature Sensor

Most air conditioners come with a low ambient temperature sensor. This is to prevent air conditioner operation during extreme cold. If you try to turn the air conditioner on despite the low temperature, there can be very costly repairs that would need to be done.

Overheating Compressor

As with any mechanical device, a compressor heats up the more it is used. During extreme cold, a compressor would need to work overtime which can lead to overheating. Using the air conditioner below the minimum temperature can damage it, or become a cause for repairs.

Freezing of Cooling Coils

While using an air conditioner, you may observe water dripping from the outdoor unit. This is condensation from the outdoor copper coils. In winter, this condensed water can freeze over. With ice frozen, air does not heat up to be thrown into the room. 

Furthermore, freezing in the outdoor unit can damage it. Running the air conditioner while frozen can puncture the cooling coils requiring a replacement. To prevent this, keep the unit off and allow the ice to thaw for a few hours. You can make the process faster by pointing a hairdryer at the outdoor unit fans and vents.

Measuring Heating Efficiency

You can measure the heating efficiency of your air conditioner using the Heating Season Performance Factor (HSPF). A higher HSPF leads to a more efficient heating system, resulting in lower energy bills.

HSPF calculations compare the total heat given by an air conditioner during the heating season with the amount of electricity used. By using the values of heating output and electricity consumed within the season, it is ensured that outdoor temperature variations across the whole season are considered.

Final Thoughts

Running AC in winter is the smart choice with modern air conditioners. With a reversible air conditioner, you can get hot air into the room. But even with a non-reversible air conditioner, you can get some fresh air in a stuffy or hot room.

Yet be careful when running the air conditioner in extreme cold, as the outdoor unit can freeze.

With these considerations in mind, you are all set to use your air conditioner in winter!
