The Role of Refrigerant in Your AC System and When It Might Need Attention
Contact Us!

Your air conditioner is the unsung hero of summer in Gresham. It keeps your home or business cool, comfortable, and livable. But one key component often goes unnoticed until something goes wrong: the refrigerant. This vital substance is what allows your AC system to remove heat from indoor air and keep your space refreshingly cool. Without proper refrigerant levels and flow, your system cannot function efficiently and may even fail entirely.


In this guide, we will explore the role of refrigerant in your AC system, signs it may need attention, and how professional AC repair services can prevent minor issues from becoming major headaches.

What Refrigerant Does in Your AC System


Refrigerant is the lifeblood of your air conditioner. It is a chemical compound that cycles through your AC system, absorbing heat from indoor air and releasing it outside. Without it, your system is just a bunch of expensive metal and wires sitting in your home.


Here’s what refrigerant does:

  • Absorbs heat: As warm air from your home passes over the evaporator coil, the refrigerant absorbs the heat.
  • Transfers energy: The refrigerant carries the absorbed heat to the condenser coil outside.
  • Cools air: Once the heat is expelled outside, the cooled refrigerant circulates back into the system to repeat the process.
  • Maintains efficiency: Proper refrigerant levels allow your AC to run smoothly and keep energy bills manageable.

Think of refrigerant as the engine oil of your AC system. It may not be flashy, but without it, everything grinds to a halt.

Common Signs Your Refrigerant Needs Attention


Refrigerant issues can sneak up on homeowners and business owners. Ignoring them can lead to costly AC repair or even an AC emergency repair situation.


Watch for these warning signs:

  • Warm or uneven airflow: If some rooms are cooler than others or your system struggles to maintain temperature, low refrigerant could be the culprit.
  • Ice buildup on coils: Frozen evaporator coils often indicate insufficient refrigerant or a leak.
  • Hissing or bubbling sounds: Strange noises can be a sign of refrigerant leaks.
  • Higher energy bills: Low refrigerant forces your AC to work harder, increasing electricity usage.
  • Frequent cycling: If your system turns on and off more than usual, refrigerant levels may be off.

If you notice any of these issues, contact a professional AC repair service immediately. Refrigerant is not something to handle on your own due to its chemical properties and the risk of damaging your system.

Why DIY Refrigerant Refills Are Risky


It may be tempting to purchase refrigerant from a local store and top off your system yourself. Resist the urge. Improper handling can cause serious problems.


Here’s why DIY refrigerant refills are risky:

  • Health hazards: Refrigerants can be harmful if inhaled or if they come into contact with skin.
  • System damage: Overcharging or using the wrong type of refrigerant can damage your compressor and other components.
  • Legal restrictions: In the U.S., only certified technicians can legally handle certain types of refrigerants.
  • Short-term solution: Adding refrigerant without repairing leaks does not fix the underlying problem.

Professional AC repair services ensure the correct type and amount of refrigerant is used, and they fix leaks that could compromise your system in the future.

How Professional AC Repair Services Handle Refrigerant Issues


Licensed technicians have the expertise and tools to diagnose and correct refrigerant problems safely.


Here’s what a professional AC repair service does:

  • Leak detection: Identifies where refrigerant is escaping and repairs the leak before refilling.
  • Precise measurement: Ensures the correct refrigerant charge for optimal performance.
  • System inspection: Checks coils, compressors, and valves for damage caused by refrigerant issues.
  • Testing performance: Confirms that airflow, temperature, and efficiency are restored.

By relying on professional service, you avoid the risk of AC emergency repair and keep your system running efficiently. It is a classic case of an ounce of prevention being worth a pound of cure.

The Importance of Routine AC Maintenance


Regular AC maintenance can help prevent refrigerant issues from developing in the first place. A well-maintained system is less likely to develop leaks or lose efficiency over time.


Maintenance routines may include:

  • Checking refrigerant levels: Ensures the system is charged correctly.
  • Inspecting coils and pipes: Detects wear, corrosion, or leaks early.
  • Cleaning air filters and coils: Reduces strain on the system and prevents ice formation.
  • Testing system performance: Confirms that cooling efficiency is optimal.

Scheduling regular maintenance with a trusted technician is like giving your AC system a regular health checkup. It keeps the system healthy, efficient, and long-lasting.

When to Call for AC Emergency Repair


Even with preventative care, refrigerant problems can become urgent.


Signs you may need an AC emergency repair include:

  • AC stops cooling completely
  • Strange hissing or bubbling noises near the unit
  • Visible ice buildup on coils
  • Sudden spikes in energy bills without other explanation

In these situations, do not wait. Turning off your system and calling a professional AC repair service can prevent further damage and restore comfort quickly.
