Signs That Your Air Conditioner Needs to Be Repaired or Replaced


Knowing the signs that your air conditioner needs repair or replacement may help you avoid more costly repairs or even failure.

Air conditioning issues often tend to manifest themselves at the most unexpected times. Often, it is on scorching days that the faulty or outdated air conditioning system is pushed to its limits. Maintaining a properly functioning air conditioner is critical for your family’s health and comfort. For that, you can hire the best services for air conditioning installation and repair in Perth.

Reliable operation can easily be achieved with regular AC maintenance. You may prevent expensive air conditioning repair services by detecting minor issues early on before they become major ones. In other words, familiarize yourself with the following indications that your air conditioning equipment needs repair or replacement.

Hot Air Instead of Cold

Nobody purchases air conditioning equipment just to look cool. An air conditioner is designed to perform a particular function: it keeps your family comfortable throughout the hot and humid summer months. During the hottest months of the year, an air conditioner is required to operate effectively. If it cannot produce delightfully cool air and instead produces warm air, call an HVAC expert like Service Emperor HVAC & Refrigeration for help.

Faulty Thermostat

Your air conditioner’s thermostat serves as the system’s command center. The thermostat determines how much cold air is required to maintain the temperature. Additionally, it takes measures to verify that it is functioning correctly. If your air conditioning system runs briefly before shutting off, or if it will not start on at all, this may be a sign that the thermostat is not correctly detecting whether the system is running or not. If you are having this problem, you should also have it inspected by a qualified HVAC expert.

Insufficient Air Supply

Similar to the warm air issue, there may be an issue with insufficient airflow. When you switch on your air conditioner, you may feel cold air flowing out at an extremely slow rate, making it difficult to circulate in the room. This is often a sign of a malfunctioning compressor, but it could also be a sign of a duct malfunction. Due to the complexity around this situation, it is recommended that you call an HVAC professional for a tune-up. A professional has the required expertise and experience to minimize the possibility of future complications.

Loud Noises

Suppose you hear grinding or scraping noises while the air conditioner runs. In that case, a belt may be sliding out of position inside the machine. Contact an HVAC professional immediately to prevent further expensive damage to other components.

Strange Smells

An air conditioner is not intended to have an unpleasant odor. If this occurs, there is an issue. For example, a pungent smell may suggest a burned-out wire within the unit. In contrast, a musty smell may indicate mold inside the unit or ductwork. A specialist must identify this issue immediately since it may result in illness for you and your family.

Insufficient Reduction of Humidity

An air conditioner’s primary function is to reduce the humidity in your home. Even in climates with low humidity, the air retains a tiny quantity of moisture. If you observe increased humidity in your home while your air conditioner is operating, the device may need repair.

Frequent Repairs

Suppose your air conditioning unit has required emergency repair service at least 3/4 times (or even more) in a matter of months. In that case, it may be time to consider replacing it and avoiding further AC repair services entirely.

Leaking Issue

If there is any moisture leaking into or around your air conditioning system, you have a problem. This may indicate the presence of a refrigerant (coolant) leak. Due to the toxic nature of Freon, consult a specialist immediately. However, this moisture could be water from a faulty or clogged condensation tube in less complicated situations.

This problem may manifest itself in a variety of ways. Water may escape from the HVAC system in certain instances. At the same time, ice may form within the AC unit on the copper coolant pipes located outside the condenser. In any case, this is a red flag and you should call a professional HVAC technician.

Excessive Electric Bill

Another sign that your air conditioning unit needs repair or even replacement is a skyrocketing energy bill that does not show any additional use. This issue may be caused by several factors, including a leak in your HVAC system’s ductwork, a faulty thermostat switch, or the air conditioning unit’s end of its lifespan. Whatever the reason, your device will need repair.

Increase of Dust

An outdated air conditioning system may have a detrimental effect on allergy sufferers. Because older units are less effective than modern ones, they have a tough time filtering out dander, dirt, and dust. As a result, controlling the quantity of dust in your house will be tough. So, we suggest you look for a replacement if this happens.

End of Lifespan

If your air conditioning system is at least ten years old, you should be grateful for its longevity and start searching for a replacement unit. Unfortunately, air conditioners do not survive more than a decade.


These indicators serve as helpful reminders for identifying a problem immediately and, in many instances, prevent the need for an HVAC unit replacement entirely. Maintaining a pleasant temperature in your house throughout the warm months requires a variety of well-working mechanics.

If you see any of these symptoms, call a licensed HVAC expert. Trying to handle repairs on your own may result in extra expenses if something goes wrong.
