No device can operate forever without eventually wearing down, and your air conditioner is no exception. It’s important to know the signs that your AC system is on its way out so you can repair or replace it before it breaks completely. Here are six telltale signs that your AC system in Severna Park, MD, is nearing a breakdown:

Poor Airflow

When your air conditioning system works optimally, you should feel consistent and steady cool air circulation throughout your home. The temperature should generally be uniform in all room areas, and the air should feel fresh.

Poor airflow often results from a clogged air filter preventing the AC system from effectively circulating the cooled air. Over time, dust and other debris accumulate on the filter, blocking airflow. Regular maintenance and changing air filters at least once every 30 to 90 days are key to addressing this issue.

Strange Noises

An air conditioner in good condition makes very little noise while operating. If your AC system starts making strange sounds like grinding, squealing or rattling, it indicates something is wrong. These noises can be due to loose parts, a failing motor or issues with the compressor.

You should pay attention to these noises, as they could lead to a need for more costly air conditioning repairs or even a full system replacement if not addressed promptly. Regular inspections and tuneups can help prevent these issues and extend the lifespan of your AC system.

Refrigerant Leaks

A refrigerant leak in your AC system often leads to a decrease in cooling efficiency and an eventual breakdown. The visible signs of refrigerant leaks include the following.

  • Build up of condensation around the system.
  • A hissing sound.
  • Ice buildup on the copper lines.
  • A foul odor.

The common causes of refrigerant leaks include physical damage to the coils, natural wear and tear or faulty installation. A refrigerant leak can cause your AC system to overwork, increasing energy consumption and utility bills. If left unattended, the problem could escalate, damaging the compressor, leading to expensive repairs or an AC system breakdown.

Not Cooling

If your AC system is running but isn’t cooling your space, it could be due to various issues. A faulty thermostat may not accurately read the room temperature due to wrong calibration and cause the AC system to run without cooling the air. Another possibility could be a refrigerant leak, which will render the AC system ineffective at cooling air.

Failing to cool puts unnecessary strain on the air conditioner, causing it to overwork and increasing the chance of premature failure. Moreover, it leads to higher energy consumption, escalating utility bills. Addressing these issues is crucial to prevent longer term damage and expensive AC repairs.


The age of your AC system can significantly contribute to its performance and efficiency. The older an air conditioning system gets, the more likely it is to encounter issues or inefficiencies.

Most modern air conditioners have smart features, such as programmable thermostats and energy-saving modes, that enhance comfort and reduce energy consumption. Upgrading to a system with modern technology is a wise investment that can deliver significant savings on energy bills in the long run.

Abnormal Electricity Bills

Sudden spikes in electrical bills could be due to an air conditioner that is overworking or inefficient. If your AC system needs repairs, it’ll work harder and longer than necessary to maintain the desired temperature, inflating electricity costs.

You can monitor your energy bills each month and look out for any anomalies or hikes in costs. If you suspect a malfunctioning AC system is driving up your energy bills, it’s best to contact a professional service technician who can diagnose the problem and perform necessary repairs.
