It’s a hot summer’s day, and you have just got home from a long afternoon shopping session. Drenched in sweat, your only escape to beat the heat is sitting under the air conditioning unit for hours at a stretch. But to make things worse, the air conditioning doesn’t seem to respond after you have turned it on. With summer in the offing, the last thing you want is an AC that doesn’t work.

The worst thing you can encounter during a season of scorching heat is an AC that just won’t start. Unfortunately, this happens to be the case with the majority of the people who use their air conditioning only during the winter. But before you can call the AC repair personnel, there are a few things you can try from your end as well.

If your air conditioning is acting strange, your best bet to get your ac back up and running is to reset it all together. This article will walk you through how you can perform a simple ac repair without spending a penny whatsoever.

Why Should You Reset Your Air Conditioner?

Given the current world situation, half of the world’s population is forced to work from home. And when working from home, there are times when you drastically need the services of an air conditioner.

However, a certain number of people only tend to use their air conditioners during the summer. This keeps the ac dormant for almost 8 months at a stretch. When it comes to electrical appliances, the best way to ensure they remain in excellent working condition is to make sure you turn them in from time to time.

You may need to reset your AC during the following scenarios.

  • Sudden Blackout
  • Power Fluctuations
  • Power Overload
  • Damaged Components

Resetting Your Air Conditioner

If your ac breaks down or starts malfunctioning, it may not always call for air conditioning repairs. However, you can try a few things from your end, such as performing an ac reset. The majority of the modern-day air conditioners come with a dedicated RESET button using which you can reset your AC. Meanwhile, some ACs have a rather complicated process when it comes to resetting.

Therefore, we will walk you through the different processes you can reset an AC of any type.


  • Always make sure you wear protective equipment such as insulator gloves and footwear when performing electrical repairs.
