  1. Water Seeping into the House

If your air conditioner leaks then the walls, floors and ceilings will also suffer damage. The best way to recognize this problem is when you notice a puddle or water stains present around the AC unit. First of all, determine the source of leakage. In most of the cases, the source is a faulty drainage pipe. Presence of a damaged pipe will have the water build up inside the unit causing a leak out. Unfortunately, if you cannot find the leakage source then simply call a technician to get the job done.

  1. AC not Generating Cold Air

Your AC is as good as dead if it doesn’t generate cold air especially in summers. There are a few steps to go through. First of all check whether the thermostat mode is set to “cool” mode or not. After making it 100% sure, check the air filters. Presence of dirty air filters can restrict the air flow resulting in units not performing cooling properly. If this too isn’t the issue then try resetting the unit by turning it off for a minute and then turning it on. Calling a technician should be the last option to consider.

  1. Presence of Dirty Air Vents

If the air vents associated with your AC are dirty then it can impact the unit’s performance significantly. In order to clean the vents you will have to remove the furniture or other items blocking the vents. After this, use a vacuum attachment in order to clean the dust and dirt.

Once this is done, you can use a damp cloth if the vacuum thing didn’t work out. But make sure that no cleaners or harsh chemicals are used as they can damage the vents greatly.

  1. Non-functional AC Remote

Imagine you came home from a hot summer day and want to turn on the AC as soon as you enter. But what you see is that the AC remote isn’t responding and has become non-functional. Before taking any bigger steps make sure that the batteries used in the remote are fresh. If this is not the issue then reset your AC by unplugging it from the main outlet for 2 – 3 minutes. After doing this, if the remote still isn’t working then the problem might be with the AC. Call a technician to find out more.

  1. AC not Blowing Air

Your air conditioner not blowing cold air is one issue but air conditioner not blowing air at all is another issue. One possible reason behind this problem might be the presence of dirty fan blades. In order to clean them, turn off the unit first and then remove the front panel. Use a soft brush or a damp cloth to remove debris and dirt.

  1. Unit not Turning ON

If your AC unit is not turning ON then it might be due to a power issue. Turn ON the circuit breaker if it has been tripped. However, if the circuit breaker is fine then check the power cord. Ensure that the power cord is plugged in securely. If all seems fine then the issue is with the AC itself. For this you need to call an expert or technician.

Is it Important to Repair an Air Conditioner?

Repairing an air conditioner is really expensive so it is important to consider your options before taking the big step. If the unit has become old and demands frequent repairs then it is time to invest in a new one. You can consider the repairing option if the issue is minor but in case of major issues you will have to replace the whole unit.

If you are unsure whether to repair or replace your air conditioner then it is advised to consult with a qualified technician first. Some people go for the replacement option because they don’t want to deal with the hassle of solving the problems that they experience while using the appliance. This approach is not at all encouraged.
