An air conditioner is one of the electrical appliances used in many homes worldwide. It can operate for a long time, free from malfunctions.

How Do I Know If My Home AC Needs to Be Recharged?

Signs that indicate if Home AC Needs to Be Recharged

When it starts to dislodge room temperature air.

You can confirm by putting your hands in front of the outlet of the AC that emits air into your home and feel the temperature change for a few minutes.

Sometimes the refrigerant in your AC may leak, causing warm air to circulate in your house.

Therefore, recharging your air conditioner can help to restore the cool air in your home again from the beginning.

Signs That Your Home AC Needs Recharging

Various indicators can make you recharge your AC. They include:

High Temperature on the Thermostat 

When the thermostat is faulty, it will frequently read to a high temperature compared to the machine’s authentic setting.

Therefore, the thermostat may end up breaking.

It may also indicate that your air conditioner is unable to keep up with highly generated heat within, and you may switch your AC off and turn it on later to allow time for cooling, then observe the changes again.

How to Determine If Your Thermostat is Broken

  • Please set it to a high temperature of between 80 to 90 degrees Fahrenheit.
  • Maintain the temperature for a maximum of 20 minutes to allow the unit to adjust.
  • Reduce the temperature gradually to 78 degrees Fahrenheit as you listen for your AC unit to turn on once more.
  • If all this takes place accurately, then the thermostat is perfect. However, you can repeat the whole process for proper assurance that the thermostat is not broken.

Frost on the Unit

The coolant in your air conditioner can quickly freeze other elements that it may encounter.

Therefore, when you observe frozen features around the unit, there is a high possibility the AC is leaking.

You should ensure that your air conditioner is charged as soon as possible so that the leaks don’t cause further damage inside the AC.

Room Temperature Air in the Vents

When the vents release warm air in your house, you should consider recharging your air conditioner unit.

Before hiring an expert to fix your AC, you should give it for 15 minutes because every air conditioner blows out some warm air when it is switched on.

Leaving it for 15 minutes also lets the air cool down effectively, not only if the refrigerant is damaged.

Usually, the AC vents blow cold air to displace the room temperature, making your house conducive to chilling with your family members.

Increase in Your Electric Bills

You can easily take note of your electric bills when your air conditioner operates throughout the day and night. 

When you notice any increase in your bills, then your AC has not been working correctly. This could be an indication that your home air conditioner requires immediate recharging. 

How to Perform an Inspection on Your Home AC

Understanding this will enable you to save finance and time and eradicate damages that may happen to the system of your AC.

Some of the air conditioner elements that may require inspection include: 


You can also visually monitor the fan besides checking on the thermostat and the air temperature getting out of the vents.

The fan should always be in motion automatically when your air conditioner is switched on, and if it fails to move, its motor might have a technical malfunction.

It would help if you do not put your hand inside the AC because it may cause the risk of unnecessary damage to the system.

You should reach out to trained personnel to fix the problem.


Air filters can get clogged with dirt and waste. If you know how to handle filters safely, the best thing you can do is ensure they remain clean and free from blockage.
