What is Refrigerant & Why is it Used in Air Conditioners?

At Indoor Air Quality, Inc., we pride ourselves on clarifying the often complex world of HVAC systems for our clients. Today, we’re unpacking a critical component of your air conditioner: the refrigerant. This key component is essential for cooling your home, yet it remains a mystery to many.

Let’s dive into what refrigerant is and why it’s crucial for your air conditioning system.

What is Refrigerant?

Refrigerant, in simple terms, is a compound typically found in either a fluid or gaseous state. It readily absorbs heat from the environment and can provide cooling through a cycle of evaporation and condensation. This unique characteristic makes refrigerant the backbone of many cooling systems.

The Role of Refrigerant in Cooling Your Home

The cooling process begins when the refrigerant, housed within your AC system’s coils, absorbs heat from the indoor air and transitions from a low-pressure gas to a high-pressure liquid. As this coolant circulates through the system, it undergoes various phase changes. This cycle of evaporation absorbs heat from your home’s interior, while condensation releases the captured heat outdoors, effectively lowering the indoor temperature. This continuous cycle is what keeps your home cool and comfortable, even during the peak of Denver’s summer heat.

Why is Refrigerant Essential?

The importance of refrigerant cannot be overstated. Without it, the air conditioning systems would be unable to transfer heat from the inside of your home to the outdoors. This process is not only crucial for maintaining a comfortable living environment but also for protecting your home’s air quality. Our team at Indoor Air Quality, Inc. ensures that your system uses the appropriate type and amount of refrigerant, adhering to the latest environmental guidelines and efficiency standards.

Maintaining Your System’s Refrigerant Levels

Ensuring your system has the correct refrigerant level is essential for optimal performance. Too little refrigerant can lead to a loss of cooling power, higher energy bills, and even system failure. On the other hand, too much refrigerant is equally detrimental. Our certified HVAC/R technicians specialize in accurately diagnosing and adjusting your system’s refrigerant levels, ensuring efficient operation and prolonging the lifespan of your investment.

Important Refrigerant Changes in 2025

Starting in January 2025, all new AC systems and heat pumps have to be manufactured with the new class of A2L refrigerants in mind. Maintenance for older and current R410a units will still be possible, but over time, the supply of refrigerant will become less available, and prices will rise. If you are thinking about replacing your air conditioner, now may be a good time. 

At Indoor Air Quality, Inc., we understand the significance of maintaining your air conditioner’s refrigerant levels, not just for the efficiency and longevity of your system but for your comfort and safety. Our team, equipped with extensive experience, certifications, and a commitment to ongoing education, is dedicated to providing prompt, reliable, and clean service across the Denver metro area. Trust in our expertise to keep your system running smoothly, making your home energy-efficient and comfortable year-round.
