Common Causes of a Buzzing AC

There are various reasons why your AC might be making a buzzing noise. Some of the most common causes include:

Dirty or Clogged Air Filters: One of the primary reasons for a buzzing air conditioner is dirty or clogged air filters. When air filters are clogged with mud, dust, and debris, it restricts airflow in your AC unit, causing the system to work harder and produce a buzzing noise.
Loose Parts: Another common cause of a buzzing AC is loose parts within the unit. With constant usage, parts such as the fan blades, motor mounts, or compressor might become loose and vibrate, resulting in a buzzing noise.
Electrical Issues: Faulty wiring or electrical components can cause your air conditioning unit to buzz. If you hear a buzzing sound when you turn on your air conditioner, it could indicate an electrical issue that needs immediate attention.
Refrigerant Leak: A refrigerant leak can also cause your AC to produce a buzzing sound. As the refrigerant levels drop, it puts more strain on the compressor and other components, resulting in a buzzing sound.
Compressor Malfunction: The compressor is an essential component of your air conditioning unit, responsible for cooling the refrigerant and circulating it through the system. If there is an issue with the compressor, it can cause buzzing noises.

AiRight Cooling, Heating & Plumbing is here to help you understand why your AC might be making a buzzing noise and provide solutions to fix the issue. Our experts have been providing top-notch AC service in Riverside since 2007, making us the go-to company for all your HVAC needs.

Solutions to Fix a Buzzing AC

If your air conditioner is making a buzzing noise, don’t ignore it. It could mean a more significant issue that ought to be addressed. Here are some solutions to fix a buzzing AC:

Clean or Replace Air Filters: Standard cleaning or replacing of your air filters is essential to maintaining a healthy and efficient AC unit. Clean and replace your filters frequently to improve airflow and eliminate the buzzing noise if your filters are dirty.
Tighten Loose Parts: Inspect your AC unit for loose parts and tighten them using appropriate tools. It is always best to leave this job to a professional HVAC technician to avoid further damage.
Address Electrical Problems: If you suspect an electrical problem, turn off your AC and contact a licensed electrician for assistance. Trying to fix electrical problems on your own can be perilous and may cause further damage to your unit or even lead to accidents.
Check and Refill Refrigerant Levels: If you suspect a refrigerant leak, contact a professional AC technician to assess the issue and refill any lost refrigerant. It is essential to address this problem immediately to prevent further damage to your unit.
Repair or Replace Compressor: In some cases, an experienced HVAC technician may need to repair or replace a malfunctioning compressor. A faulty compressor can cause your AC to produce a buzzing noise or even shut down the unit entirely.

Paul.

AiRight sent Gustavo Lizarraga to resolve a shower drain issue which required going down into the crawl space under the house. Gustavo corrected shower and bathtub ABS sewer line piping and replaced an internally corroded piece of vertical cast iron pipe. Gustavo was polite and efficient, provided detailed pictures of his work and the piece of cast iron pipe he removed. Gustavo is an excellent plumber.

My AC stopped blowing out cold air. I had another big company come out to take a look they spent 1 hour doing diagnostics and charged me $110 just for looking and wanted to charge me $8100 for the repair and I felt like I was being swindled so I called AiRight cooling for a second opinion and they sent out Jackie who took 15 minutes to figure out the problem and fixed it for $650. Jackie was professional, efficient and most of all honest. I just saved $7500!! Thanks to Jackie from Airight Cooling
