Expert Tips for Prolonging the Lifespan of Your AC System

Having an air conditioning system is essential for maintaining a comfortable living environment, especially during scorching hot summer days. While AC systems generally have a long lifespan, there are various factors that can affect their performance over time. As a leading HVAC company in Stoney Creek and Ancaster, ON, our experts at & G Heating Air Conditioning & Ventilation have extensive experience working with AC systems and know exactly what it takes to improve their longevity and maintain their efficiency. We will be sharing essential tips that can help you prolong the life of your air conditioning system and make sure it works at its best.

Efficient and Cost-Effective Usage

Firstly, it is important to ensure that your air conditioning unit is used efficiently and does not waste energy. Making smart and energy-conscious choices while using your system can help prevent excessive wear and tear on its components. One way to achieve this is by setting the thermostat at a comfortable temperature – ideally between 22 and 24 degrees Celsius – and resisting the urge to drastically lower the temperature on exceptionally hot days. This practice will reduce the strain on your AC system and promote its longevity.

Another energy-efficient practice is to use a programmable thermostat that adjusts the temperature settings automatically based on your schedule and preferences. This ensures that your system does not run at full capacity when it is not needed, thus preventing undue stress on its components. In addition, consider installing energy-saving devices like solar shades or blackout curtains, which can help reduce the heat entering your home and alleviate the need for constant cooling.

Proactive Maintenance Is Key

Regular maintenance plays a crucial role in extending the lifespan of your AC system and ensuring it operates at peak efficiency. Many potential issues can be identified and resolved during routine maintenance visits, preventing them from escalating into major problems that could lead to costly repairs or even system replacement. Here are some critical maintenance tasks to be performed routinely:

  1. Inspect and Replace Air Filters – Dirty or clogged air filters restrict airflow, causing your AC system to work harder than necessary. Check your filters monthly and replace them as needed to maintain optimal airflow and prevent strain on the system.
  2. Clean and Inspect the Condenser Coil – The condenser coil, located in the outdoor unit, helps dissipate the heat absorbed by the refrigerant. A dirty or damaged coil will not dissipate heat efficiently, placing added pressure on the compressor and other components. It is essential to clean and inspect the coil annually to ensure its proper functioning.
  3. Check Refrigerant Levels – Incorrect refrigerant levels in your AC system can impact its cooling efficiency and lead to added wear on its components. Make sure that your system’s refrigerant level is checked during routine maintenance to ensure it is within the recommended range.
  4. Inspect and Clean the Evaporator Coil – The evaporator coil absorbs heat from your home’s air and transfers it to the refrigerant. A dirty or damaged coil can negatively impact your AC system’s performance and efficiency. Schedule an annual check and cleaning of the evaporator coil as part of your routine maintenance.

Seasonal Readiness

Another important step in prolonging the life of your AC system is to ensure it is ready for the changing seasons. Prepare your system for the summer months by checking for any potential issues and addressing them proactively. Preparing your AC unit for the winter months is equally crucial by taking proper precautions to protect it from harsh weather and freezing temperatures. This includes clearing any debris from around the outdoor unit, insulating exposed pipes, and installing a protective cover if necessary. Ensuring your system is ready for seasonal transitions will help maintain its efficiency and longevity.

Upgrading to a More Energy-Efficient System

Technology has advanced rapidly over the years, and modern air conditioning systems are significantly more energy-efficient than older models. If your AC system is aging and consuming substantial amounts of energy, it may be time to consider investing in a newer, more efficient system. Upgrading to a more energy-efficient AC unit can help reduce your energy bills and environmental impact while also extending the lifespan of the system through less wear and tear on its components.


By following these expert tips and keeping up with regular maintenance, you can effectively extend the lifespan of your AC system and maintain its optimal performance. Remember, proactive maintenance and efficient usage are essential aspects of prolonging your air conditioning unit’s life.
