In most cases, especially in residential applications, you should not run your air conditioner when outdoor temperatures are below 60 degrees. The air conditioner does function, but you are going to burn out the compressor fairly quickly.
The point being, not only does an air conditioner not make you sick, but it can also help you recover more quickly.
When temperatures outside become higher than 100 degrees Fahrenheit, the air conditioning system can consume more energy and begin to malfunction or fail. Most air conditioning systems are designed to function with outside temperatures of 100 degrees or less.
Second, your air conditioner might have a low-temperature sensor. To avoid damage, this sensor will prevent the unit from turning on in cold weather. So you may not be able to use your air conditioner when it's cold outside even if you'd like to. Third, your compressor may heat up excessively from overuse.
But you shouldn't run your AC if the temperature is below 60°F. Heat pumps: Modern heat pumps are effective at around 25 to 30°F. Ductless mini-splits: Avoid using the cooling function when temperatures fall below 60°F.
Air conditioners that contain condensing units are not designed to be run in cold weather at all. The units contain heavy grade oil that lubricates the compressor. This oil works best in warm conditions and during cold weather it becomes thicker. This means that it won't be lubricating the compressors properly.
TOM: There's no reason to “warm up” the air conditioner before using it, or to warm up the engine before turning on the AC. The engine is more than capable of powering the air conditioner right away without any adverse effects, and the AC is ready to work within seconds.
Cooler temperatures at night can cause our immune system to slow down. This can make you more susceptible to conditions like common cold or a dry cough. Or else, you might wake up with a sore throat. If the AC unit is not clean, it will circulate germs and other airborne contaminants like dust mites, pet dander, etc.
A common rule of thumb is that most models can function properly only above 68 degrees Fahrenheit. Any lower temperature will result in the system freezing up. In addition to a frosty refrigerant, the piping and coils could also become covered with ice.
The World Health Organization (WHO) recommends setting your thermostat no lower than 64 degrees (F) in the Winter months while people are in the home.
And sometimes it may simply be too cold to run—period. Temperatures below -8 degrees Fahrenheit can increase your risk of frostbite and hypothermia, according to the American College of Sports Medicine, and it's possible for tissue injury to occur in less than 30 minutes in these conditions.
Yes, you should turn off your AC if it's not cooling. Continuing to run a malfunctioning AC can strain the compressor and other components, leading to more severe and costly repairs. If there's a refrigerant leak or airflow issue, running the AC can cause the evaporator coils to freeze, compounding the problem.
How does the outside temperature affect air conditioners. Reduced efficiency: As the outside temperature climbs, your AC has to work harder to maintain the desired coolness indoors. Imagine trying to scoop hot coals in the midday sun compared to a cool evening.
You need your air conditioner to keep your home comfortable during the hottest months, but when the temperature is at its peak, you need to be careful. If you set the thermostat too low, it strains the AC. This leads to air conditioning malfunctions and costly repairs.
Air conditioners can't tolerate temperatures below 60 degrees Fahrenheit. In extreme cold, the AC's compressor can get overworked as it struggles to function. At best, it will need significant repairs; at worst it may completely fail.
Most HVAC manufacturers recommend users don't run their air conditioners for long periods of time if the temperature drops below 60 degrees. If you use it in lower temperatures, you risk compressor failure and frozen coils.
Common Cold Or Other Respiratory Issues
The cold conditions further dehydrate the lining within the nose, making it more susceptible to infection. As viruses thrive best in super-low temperatures, avoid running your conditioner when it is cold.
Air conditioners are designed for comfort cooling, not reaching extremely cold temperatures. The exact minimum can vary by model, but most AC units will cool a room down to around 16°C (61°F) or 18°C (64°F).
The Myth of Air Conditioning Causing Colds
This myth has been around for a long time, but it's not entirely true. Air conditioning does not cause colds. Colds are caused by viruses, not by air conditioning. However, air conditioning can indirectly contribute to the spread of colds and other respiratory illnesses.
Setting your air conditioning to 72°F is generally considered a comfortable indoor temperature for many people. It strikes a good balance between comfort and energy efficiency, making it a popular choice for residential settings.
Operating your AC unit can help to remove moisture from the air inside your home, which in turn helps to defog windows and doors. Finally, it's a good idea to run the AC at least periodically during the winter so that the oil keeps circulating throughout it.
Lowering the temperature too much causes your air conditioner to operate longer, causing more wear and tear on it as well as higher utility bills.
