At Air Max, we understand how important a well-functioning air conditioning system is for your comfort. Over time, refrigerant levels can deplete, impacting your unit’s cooling efficiency. Below, we’ll explain how to tell if your home or commercial aircon needs a regas, why it happens, and what steps to take to restore optimal performance.

What Is Aircon Regassing?

Aircon regassing is the process of replenishing the refrigerant gas inside an air conditioning unit. The refrigerant plays a crucial role in cooling the air, and without sufficient levels, the system cannot operate effectively.

Home air conditioners are sealed systems, meaning they should not require frequent regassing unless there is a leak or component failure. However, commercial air conditioning systems may experience more frequent refrigerant depletion due to their higher workload.

How to Know If Your Aircon Needs Regassing

1. Weak or Warm Airflow from the Vents

If your aircon is no longer producing cold air, the refrigerant levels may be too low to support efficient cooling.

2. Longer Cooling Times and Inconsistent Temperatures

A properly functioning aircon should cool a room quickly. If it takes longer than usual, low refrigerant levels might be the issue.

3. Ice Build-up on the Evaporator Coils

Low refrigerant can cause the evaporator coils to freeze, restricting airflow and reducing cooling efficiency.

4. Hissing or Bubbling Noises

These sounds could indicate a refrigerant leak, which needs urgent professional attention.

5. Increased Energy Bills

If your aircon is working harder to maintain the same temperature, it may be using more energy due to low refrigerant levels.

6. Visible Refrigerant Leaks

Oily stains or puddles near the aircon unit could signal a refrigerant leak, which requires immediate servicing.

Do Home Air Conditioners Need Regassing?

Unlike car air conditioning systems, home air conditioners should not require regular regassing unless a leak is present. If your aircon needs frequent regassing, there may be an underlying issue that needs to be fixed.

How Often Does Aircon Need Regassing?

The frequency of regassing depends on several factors:

• Home air conditioners rarely need a regas unless there is a leak.
• Older units may require regassing every 5 to 10 years if refrigerant loss occurs.
• Commercial aircon systems, due to higher usage, may need a regas every 2 to 5 years.
• Car air conditioning units generally require regassing every 2 to 3 years.

If refrigerant levels drop frequently, it’s crucial to inspect for leaks before proceeding with a regas.

House Air Con Regas vs. Commercial Aircon Regas

Home Aircon Regas

• Needed only if there’s a leak.
• Symptoms include reduced cooling, ice build-up, and higher energy bills.
• Requires professional diagnosis before regassing.

Commercial Aircon Regas

• More frequent due to heavier use and larger system complexity.
• Essential for business environments, offices, and retail spaces.
• Regular servicing helps prevent expensive breakdowns.

What to Do If Your Aircon Needs Regassing

Step 1: Inspect for Leaks

Before regassing, a technician should check for leaks to prevent further refrigerant loss.

Step 2: Identify the Correct Refrigerant Type

Using the wrong refrigerant (e.g., R-410A, R-32, R-22) can damage the system. Always ensure the correct gas is used.

Step 3: Professional Regas Service

Regassing should always be carried out by a licensed aircon technician, who will:

• Evacuate any remaining refrigerant
• Repair leaks if necessary
• Refill the system to manufacturer specifications

Proper Maintenance to Avoid Regas Issues

Regular air conditioning maintenance can help prevent refrigerant leaks and reduce the need for regassing. Here are some essential maintenance tips:

• Clean or replace air filters every 1 to 3 months to ensure proper airflow.
• Schedule annual professional servicing to check for potential refrigerant leaks.
• Inspect the evaporator and condenser coils for dirt buildup and clean them regularly.
• Ensure proper insulation around refrigerant lines to prevent leaks and inefficiencies.
• Monitor energy consumption—a sudden increase may indicate a refrigerant issue.

By following these steps, you can extend the lifespan of your air conditioning system and minimize the need for regassing.
