AC Blower Cleaning for Optimal Air Conditioning

You might not realize it, but nestled inside your air conditioner is an unsung hero: the blower. When it comes to the health and efficiency of your air conditioning system, regular AC blower cleaning plays an integral role. This guide aims to take you through the ins and outs of blower cleaning, demonstrating just how important this often overlooked task can be.

The AC Blower – The Heart of Your Air Conditioner

Imagine the blower motor as the heart of your air conditioning system, and the blower wheel as the veins, circulating cool, refreshing air throughout your home. When your blower fan is free from dirt and debris, it operates smoothly and efficiently. However, a buildup of dust on the blower can hinder this process, affecting your comfort and the overall performance of your air conditioner.

  • Your AC isn’t as cool as it used to be: Your air conditioner seems to be working overtime, yet the cool air just isn’t what it used to be. A dirty blower could be the culprit.
  • Your AC is making strange noises: Are you hearing unusual sounds from your air conditioner? The blower motor shouldn’t sound like it’s struggling. If it does, dust and debris might be causing the problem.
  • Your electricity bill is climbing: An overworked, dirty blower can place additional strain on your air conditioning system, leading to increased energy consumption.
  • You’re experiencing allergy symptoms or respiratory issues: The blower fan doesn’t just circulate air; it can also circulate dust if it’s dirty, which can affect your health.

Why Regular AC Blower Cleaning Matters

  • Stay cool, effortlessly: A clean blower ensures effective air movement, which means your air conditioner can do its job properly – keeping you cool.
  • Save on your bills: If your air conditioning system doesn’t have to battle against a dirty blower, it won’t have to work as hard. This can lead to energy savings, and Energy Star offers further advice on improving your system’s energy efficiency.
  • Breathe easy: Cleaning your blower fan reduces the amount of dust that gets circulated in your home, which can contribute to better air quality.
  • Keep your AC around for longer: Just like regular servicing can extend the life of your car, regular maintenance, including blower cleaning, can extend the lifespan of your air conditioner. With proper maintenance and care, a new high efficiency air conditioning system can provide cooling for a good 15 to 20 years​
