Here are some common problems and when to call Bighorn Automotive

Summer in Colorado is glorious, but it’s a lot less glorious if your car’s air conditioning isn’t keeping up. There’s nothing worse than turning on the AC on a hot day only to be met with weak airflow, warm air, or strange noises. While some minor issues might have simple fixes, knowing when to bring your vehicle to an expert can save you discomfort and bigger repair bills down the road.

Let’s break down some common AC problems and help you decide if it’s a DIY fix or if it’s time to call the pros at Bighorn:

Common AC Problems and What They Might Mean

My AC is blowing warm air

• Low Refrigerant
  • This is the most common culprit. Refrigerant (or Freon) is the chemical that cools the air. A leak in the system can cause it to run low.
• Clogged Condenser
  • The condenser helps cool the refrigerant. If it’s blocked by leaves, dirt, or debris, it can’t do its job efficiently.
• Faulty Compressor
  • The compressor is the heart of your AC system, pressurizing the refrigerant. If it’s failing, your system won’t cool.
• Electrical Issue
  • A blown fuse or a problem with the electrical system can prevent the AC from engaging.

My AC airflow is weak

• Clogged Cabin Air Filter
  • This is a common and often overlooked issue. A dirty filter restricts airflow into the cabin. It’s usually a simple replacement!
• Blower Motor Problems
  • The blower motor is responsible for pushing air through your vents. If it’s weak or failing, you’ll notice reduced airflow.
• Vents Blocked or Damaged
  • Less common, but physical obstructions or damaged ducts can also restrict air.

My AC is making strange noises

• Hissing or Squealing
  • This can indicate a refrigerant leak or a failing compressor clutch.
• Clicking
  • Often heard when the AC engages, a loud or persistent clicking might signal a compressor or clutch issue.
• Rattling or Clunking
  • Could point to loose components, debris in the blower motor, or a failing compressor.
• Gurgling
  • Sometimes heard when the system has too much or too little refrigerant.

My car smells funky when the AC is on

• Mold / Mildew Build-Up
  • This is common in the evaporator core (where the air gets cold) due to condensation. Anti-bacterial treatments can often resolve this.

When to Seek Professional Help and Why Bighorn is Your Go-To
