Why does my AC work at night but not during the day car?

In short, the problem isnt with the AC, its with the car coolant system. The AC doesn’t work during the day when it’s hottest in order to preserve itself and the car engine.

Why does my car AC work sometimes and not others?

Intermittent cooling is often caused by the components of your vehicle’s AC system freezing up. Typically an iced over evaporator is the culprit. An evaporator covered in ice can’t cool the air, so you would have to wait until the ice melts, which is why the cold air eventually returns.

Why does my AC work better at night?

Your AC has more capacity and is more efficient at night when it’s cooler than it is during a hot afternoon. As your electricity bills begin to drop with the onset of cooler weather, now you know that it’s not just because less heat is getting into your house.

Why does my car AC stop working when it’s hot?

The hotter it is outside, the harder the air conditioning in your vehicle has to work. Rising outside temperatures put extra strain on your entire vehicle and its cooling system, from the battery and belts to hoses and fluids, requiring each part to work overtime to keep your vehicle cool.

Why does my car AC take time to cool?

Late-engaging radiator fans, mispositioned temperature (blend air) doors, weak compressors, outside air flap failures, and heat coolant valve malfunctions all cripple air conditioning units. A trusted repair shop will examine your vehicle thoroughly to account for the cause so that we can determine and fix the problem.

Why does my car AC only work in the morning?

The AC will only chill air about 25 to 30 degrees cooler than the air that enters the system. So, as the day gets warmer, if the air entering is from the outside, the air coming in will be warmer as opposed to the air continually circulating through the cabin and getting progressively cooler.

Why does my AC take awhile to get cold?

One of the most common reasons why an AC takes longer to cool your home is because of a dirty air filter. You see, when a filter becomes clogged with dirt and debris, it restricts the amount of air the AC can bring into the indoor unit to be cooled.
