How do i Know If My AC Needs Cleaning?

Keeping your air conditioning unit in good working order ensures your home stays comfortable throughout the year. A critical aspect of AC maintenance is regular cleaning. But how do you know when your Residential Heating and Air Conditioning in Santa Rosa needs cleaning? Here are some signs to look out for

Reduced Airflow

If your air conditioning unit is not producing as much cool air as it used to, it may be due to a clogged or dirty filter. When filters become clogged with dirt and debris, they can restrict airflow, reducing the efficiency of your AC unit.

Unpleasant Odors

If you notice a musty or unpleasant odor coming from your AC unit, it may be due to mold or mildew growth inside the unit. Mold can thrive in the moist, dark environment of an AC unit, causing unpleasant smells and potentially exacerbating respiratory issues.

Visible Dust and Debris

If you notice visible dust and debris on the surfaces of your AC unit, it’s a clear sign that it’s time for a cleaning. Dust and debris can accumulate on the evaporator coils, reducing their effectiveness and making your AC unit less efficient.

Increased Energy Bills

If you notice a sudden increase in energy bills, it may be due to an inefficient air conditioning unit. When your AC unit is dirty, it has to work harder to produce the same amount of cool air, leading to higher energy bills.

Strange Sounds

If you hear strange sounds from your AC unit, such as banging, rattling, or squeaking, it may be due to dirt and debris buildup. These sounds can indicate that the unit’s components are working harder than they should be, potentially leading to damage or breakdowns.

Benefits of Regular AC Cleaning

Regular AC cleaning can help prevent these issues and keep your unit running smoothly. Here are some of the benefits of regular AC cleaning:

  1. Improved Energy Efficiency: A clean AC unit can work more efficiently, reducing energy bills and saving money.
  2. Longer Lifespan: Regular cleaning can help extend the lifespan of your AC unit, saving you money on costly repairs or replacements.
  3. Better Air Quality: A clean AC unit can improve the air quality in your home, reducing the risk of respiratory issues and allergies.
  4. Increased Comfort: A well-maintained AC unit can provide consistent, comfortable cooling throughout your home.

When to Call a Professional

While homeowners can do some basic AC cleaning, it’s often best to call a professional for more thorough cleaning and maintenance. A professional AC technician can comprehensively inspect your unit, identify any issues, and provide the necessary cleaning and repairs.

Here are Some Signs that it’s Time to Call in a Professional:

  1. Limited Access: If your AC unit is located in a hard-to-reach area or requires special tools to access, it’s best to call in a professional for cleaning.
  2. Mold or Mildew Growth: If you notice mold or mildew growth in your AC unit, it’s best to have a professional address the issue to ensure that it’s adequately removed and doesn’t spread to other areas of your home.
  3. Complicated Repairs: If your AC unit requires more extensive repairs, such as a refrigerant leak or compressor failure, it’s best to leave the repairs to a professional.
  4. Lack of Experience: If you’re not experienced with AC maintenance and cleaning, it’s best to leave the task to a professional to ensure it’s done properly and safely.


Regular AC cleaning is crucial to keep your unit running smoothly and efficiently. If you notice any of the above signs, it’s time to give your AC unit a good cleaning. And if you’re not comfortable performing the cleaning yourself or notice more complicated issues with your unit, it’s best to call in a professional. You can enjoy a comfortable, healthy, and energy-efficient home by investing in regular AC cleaning and maintenance. So, schedule regular maintenance with a trusted HVAC professional to keep your AC unit in top shape.
