Harms Of Using Air Conditioners During Heavy Rainfall

Everyone likes the rain; rain is a good thing, and it gives us a good feeling. But rain can be a blessing as long as it is limited. If it’s heavy rainfall, then it can pose severe damage. Here we are going to see the harm in using air conditioners during heavy rain.

 

  • Lightning strikes

Lightning strikes to the home are rare, but it is a definite possibility during heavy rainfall; the electrical service drop, where your household lines are connected to the house on the roof is a very crucial point for lightning strikes. When lightning strikes this point, it can cause a power surge through your home’s electrical system; within this fraction of a second, five billion joules of energy will be sent to the wiring, which can cause severe damage to your air conditioner if it is in operation. Also, it can melt the plug into your unit.

  • Debris

Usually, the rain will come with its best friend; wind. Wind will carry all sorts of debris which can get clogged into your air conditioner. If an excessive amount of debris has been clogged into your AC system, it can cause some damage to it. So it is better not to use the air conditioner when the rain is accompanied by wind, and it is better to cover your AC system. Blustering wind may knock some objects against your AC unit, you should check your system before running it after any intense wind and rain.

  • Corrosion

Internal corrosion can occur when the AC system is running or improperly wrapped during heavy rainfall. If you are running your air conditioner during heavy rain, then your AC’s internal unit will get moisture from the wind; so when you turn off the  AC, this moisture will be trapped inside the AC system, and it can build up. This can cause the wire and rubber rotting, plus it will create rust over the metal parts of your AC system. The lack of ventilation when it is moist will promote the growth of mould and mildew, and creates an attractive nesting ground for the vermin and insects. So it is advisable to purchase a proper cover with the proper ventilation holes and use it to cover your AC unit during heavy rainfall.

  • Flooding

The more it rains, the more water can rise, and if the water stands for a particular period, it can harm the moving parts inside your air conditioner. So it is advisable to have a professional inspection before turning on the air conditioner, and it is better to turn it off during those scenarios. The stagnant water under your home or in your basement can enter your furnace heat or blower compartment, and that can cause some damage to your air conditioner.

  • Short circuit

The short circuit is one of the common issues that can arise when using the air conditioner during heavy rainfall. When there is heavy rainfall, there is a chance that some drops of rainwater can get into your AC system. If the AC is turned off during that time, it is not a big deal, running your air conditioner can cause a short circuit in your AC system. Your air conditioner’s wet system can cause an abnormal connection circuit between two nodes of an electric circuit intended to be at different voltages. Voltage fluctuation is another common issue that can arise during heavy rainfall. When it is raining the voltage may fluctuate, and if you are running your air conditioner during that time, it must damage your AC system.

In any of the above-mentioned scenarios, if the air conditioner is damaged, you should wait for things to settle down and then contact the best air conditioning professionals near you.
