7 Typical Indications Your Air Conditioning System Needs a Repair

Do You Think Your Air Conditioner Needs Repaired?

When was the last time you had your heating and cooling system cleaned and inspected? When were the ducts cleaned last? Sometimes the problems we discover with the air conditioning systems are avoidable and many that turn into costly repairs, which can be found and corrected before they become a significant problem.


Issues with the HVAC system can range from the simple to the complex, but they all result in one thing – lowering the efficiency of the air conditioner. Knowing the tale tell signs that your AC needs repair can help you act accordingly when the time comes. Some of the typical indications of problems with your air conditioning system include:

  1. Strange Odors

Any funky smell is coming from the HVAC vents is a reason to worry. The odors may be due to burnt wire insulation, the presence of mold, or a dead animal in the ductwork. In most cases, the remedy for this is to clean the air conditioning system.

  1. Moisture Accumulation

Sometimes, you may come across some mold and mildew in the HVAC system. Such a matter should be a reason to worry since the air conditioning systems are designed to stay dry. The presence of mold and mildew is an indication of the existence of moisture or water in the system, and this can be attributed to a broken condensate drain or a leak in the system. Having the HVAC looked over as soon as possible is essential. It will lower the risk of having a house with a mold infestation that is spread by the AC system via the ductwork and vents. It also ensures that you have proper air conditioning in your home.

  1. Poor Air Flow

If the air conditioner is pumping less air than usual, the problem may be with a fan that is not pushing air through the ducts leading to the reduced flow of air. The failure may be attributed to a blown motor in the fan, or the fan control board may be faulty, the fan may be damaged due to dirty air finding its way to the fans since the filters are not working.

  1. Issues With The Thermostat

The air conditioner unit may be working, and there may not be any issues with the ductwork and vents, but temperatures around the house may be uncomfortable. The problem could be the thermostat. You may see the system is running at a temperature setting of 75 degrees, but the home will feel like it is more than 10 degrees off. This could be happening from a faulty thermostat that needs to be replaced or repaired.

  1. Strange Sounds

Most air conditioning systems are designed to be silent when running. If your AC starts making weird noises such as those of metal rubbing against metal, that is a clear indication of problems that need fixing. The issue could be a loose belt, a broke component, or debris.

  1. Failure To Blow Cold Air

If the AC system suddenly fails to pump cold air through the vents, then the system needs to be repaired. Such a state will have the HVAC system working overtime to keep the indoor temperatures at a desired level. The possible culprit for these issues may range from low or leaking refrigerant, leaking ductwork, or a faulty condenser. Whichever the cause, the sooner this is checked and addressed the better. It will help lower your power bill and ensure your indoor temperatures are comfortable.

  1. Increasing Energy Bills

The HVAC systems are reputed to be the largest energy consumers in most homes with the rate of consumption spiking up during winter and the summer months. The amount of power used during the last season may be lower than the current one, but this should be a cause for concern if you note a steady rise in the energy consumption rate because it could be an indication that you should have the AC unit inspected. Also, keep in mind that all of the above issues can increase the power consumption rate of the AC system.
