Common Air Conditioner Maintenance Mistakes Which Costs You Money

Maintaining your air conditioning unit is essential for its optimal performance and longevity. However, certain common mistakes in air conditioner maintenance can cost you money. From neglecting the indoor unit and dirty filters to overlooking professional servicing, these mistakes can lead to increased electricity bills and expensive air conditioning repairs. This blog will explore the most common air conditioner maintenance mistakes that can impact your finances. By understanding these pitfalls and learning how to avoid them, you can ensure efficient cooling, reduce repair costs, and keep your electricity bills in check.

Common air conditioner maintenance mistakes

People make several common mistakes when it comes to AC maintenance. By being aware of these mistakes, you can avoid potential problems and ensure your air conditioner operates at its best. Here are some common air conditioner maintenance mistakes to avoid:

  • Neglecting Regular Filter Cleaning/Replacement: One of the most common mistakes is neglecting to clean or replace the air filters regularly. Dirty air filters restrict airflow, forcing the AC to work harder and reducing energy efficiency. It’s important to clean or replace the filters every one to three months, depending on usage, to maintain proper airflow and prevent dust and allergens from circulating.
  • Failing to Clean the Outdoor Unit: The outdoor unit of your air conditioner can accumulate dirt, leaves, and debris over time, obstructing airflow and reducing efficiency. It’s crucial to clean the outdoor unit regularly, removing debris and ensuring the fins are not bent or damaged. A clean and properly functioning outdoor unit contributes to optimal cooling performance.
  • Incorrect Thermostat Settings: Setting the thermostat at extremely low temperatures doesn’t cool your home faster; it only wastes energy and increases your electricity consumption. Setting your thermostat temperature to a comfortable level and avoiding drastic temperature fluctuations is recommended. Using programmable thermostats can help optimise energy usage and maintain consistent daily temperatures.
  • Ignoring Ductwork Maintenance: Overlooking the maintenance of your ductwork can lead to reduced efficiency and poor indoor air quality. Leaky ducts can cause air loss and uneven cooling throughout your home. Inspecting and sealing any leaks in your ductwork is important to ensure that cool air reaches all areas of your house efficiently.
  • Skipping Professional Maintenance: While there are many maintenance tasks you can handle yourself, it’s essential to schedule regular maintenance at least once a year. Professional technicians have the expertise to inspect and service components that may not be accessible or require specialised knowledge. Regular professional maintenance helps identify potential issues early on, preventing costly air conditioner repairs and maximising the lifespan of your AC system.
  • Inadequate Cleaning of Outdoor Unit: Neglecting to clean the outdoor unit of your air conditioner allows dirt, debris, and vegetation to accumulate, obstructing airflow and reducing cooling efficiency. This obstruction forces the system to work harder, increasing energy consumption and bills. Moreover, a dirty outdoor unit can damage the compressor, resulting in expensive repairs or replacements.
  • Improper Thermostat Usage: Incorrect thermostat settings, such as setting the temperature too low or running the AC when not needed, can lead to excessive energy usage and wasted money. Cooling your home more than necessary strains the system and consumes more energy than required. Proper thermostat programming and temperature settings based on occupancy and comfort level can save energy.
  • Lack of Regular Maintenance: Skipping regular servicing or AC maintenance allows simple repairs to escalate into major problems over time. Small problems, if left unaddressed, can lead to system breakdowns, costly repairs, or even the need for a complete AC replacement. Regular maintenance by a professional air conditioner technician helps identify and fix potential issues early on, saving you from expensive repairs or premature AC replacement.
  • DIY Repairs and Maintenance: Attempting DIY repairs or maintenance without proper knowledge and experience can cause more harm than good. Making mistakes during repairs may lead to further damage and costly repairs by a licensed technician. It’s important to leave complex AC repairs and maintenance tasks to qualified professionals to ensure effective and safe solutions.
