A/C Problems Caused by a Dirty Filter

Your air filter plays a crucial role in not only keeping the air that comes out of your air conditioner clean, but also making sure that your system runs smoothly and efficiently. When it doesn’t, one of the main culprits can be a dirty filter.  

There are many A/C problems caused by a dirty filter, which you can potentially avoid simply by changing or cleaning your air filter more often. This can prevent a number of issues, improve energy efficiency, and help you avoid spending money on unnecessary A/C repairs.  

Read on to learn more about the seven most common A/C problems caused by a dirty filter, plus how you can prevent breakdowns and provide a healthier indoor environment with better air quality.  

A/C Problems Caused by a Dirty Filter 

  1. OverheatingIf your air filter is clogged, your air conditioner has to work harder to compensate for the air flow blockage. This can lead to system failures by causing your blower motor to overheat. 
  2. Poor Air QualityDirt and other particles get trapped in your air filter and if it’s clogged these are then released into your home. If there are any asthma sufferers or people with respiratory allergies in your home, it’s particularly important to keep your air filters clean. Allergens will build up in your duct system and you may even end up with mould problems.  
  3. Short-CyclingYour A/C will occasionally cycle on and off throughout the day. Having a dirty filter can cause those cycles to become more frequent than needed. You will experience uncomfortable temperature changes, wasted energy, and unnecessary noise.  
  4. Uneven CoolingA clogged air filter causes airflow issues and is detrimental to your A/C’s cooling power. In this case it’s more difficult to reach your desired indoor temperature levels and you’ll notice inadequate cooling that leaves you with hot and cold spots and higher costs.  
  5. Frozen Evaporator CoilsA dirty air filter can restrict the flow of cold air, causing it to build up inside your A/C unit and lower the internal temperature. Over time, this build-up of cold air can result in ice forming on the evaporator coils. The coils won’t receive enough heat and this can cause your unit to shut down in the process.  
  6. Wear and TearA dirty filter will cause unnecessary wear and tear that can lead to more serious maintenance issues along the line. You could even end up having to replace your A/C unit a year or two sooner, and you’ll be paying for costly repairs in the meantime.  
  7. Reduced Energy Efficiency. An A/C unit with a dirty filter uses more power to try and cool your home. You’ll end up with a system that’s not performing at its best and increased costs on your energy bills. 

Prevent all of these issues from happening by cleaning or changing your air filters once a month as a guideline. Regular maintenance check-ups will also help keep your system in good condition.
