How Does AC Refrigerant Work?
If air conditioner refrigerant had a superpower, it would be absorbing heat from the indoor air. Your air conditioner has a refrigerant coil, which holds refrigerant in its liquid form. The refrigerant absorbs heat from the warm air within your home and disperses it outdoors.
How does refrigerant do all of that? With the help of other AC components like the blower fan. For instance, the fan blows warm air from your home over the evaporator coil so the refrigerant can absorb its heat.
All the parts of an AC system work together to ensure a continuous flow of cool air into your home until your desired temperature is reached. Nothing will work without the refrigerant, but the refrigerant also cannot do the job alone.
Different Types of AC Refrigerant
Until January 1, 2020, R-22 was the refrigerant used in most air conditioning systems. Also known as Freon, it contributed to the erosion of the ozone layer in the 1980s.
After scientists and manufacturers developed a suitable replacement for R-22 called R-410A (also known as Puron), it was gradually phased out.
While some R-22 AC systems are still operating, repairing one is increasingly expensive due to the difficulty in sourcing parts and the obsolete refrigerant.
In September 2021, the Environmental Protection Agency (EPA) issued a mandate requiring the industry to remove the use of hydrofluorocarbons (HFCs) in R-410A. With the mandate, the industry will phase R-410A out in 2023.
R-454B will likely become the new standard for residential AC refrigerants. HVAC technicians will need new certifications to purchase and handle this new option.
If you have any questions about refrigerant changes, our highly-skilled technicians at Reliable Air keep on top of industry knowledge, training, and certifications. We will ensure you have the correct type of refrigerant in your AC. Our team will help you determine when the right time has come to upgrade to a system that utilizes a healthier and more affordable refrigerant.
Why Your AC Needs Refrigerant
Do I need AC refrigerant, and why? Air conditioning systems maintain consistent levels of refrigerant. The same refrigerant circulates through the AC in a closed loop for years without problems. When levels start to run low, the problem is a leak in the compressor or refrigerant lines.
An initial sign of low refrigerant levels is less cool air flowing through your vents. Remember, refrigerant plays such an important role that your AC cannot produce cool air without it. A refrigerant leak means there isn’t enough refrigerant absorbing the warmth in your indoor air to cool your home.
Low refrigerant levels can also impact your evaporator coil and other components of the system. All parts depend on one another to function, so your system will gradually break down as refrigerant levels get lower.
If you suspect your AC system has a refrigerant leak, contact an HVAC technician to repair the leak and increase the refrigerant levels to keep your system operating efficiently. Trained technicians have the necessary certification to purchase and replenish your refrigerant.
The Importance of Routine AC Maintenance
How will you know when your AC needs more refrigerant? You could just wait until the coils get cold and you start to experience less and less cool air reaching your home. That could compromise your AC and lead to emergency repairs that are costly and unnecessary.
Ideally, you will call our experienced technicians for routine maintenance at least once a year. Our technicians can check your refrigerant levels and will ensure your system has what it needs to operate efficiently. We can inform you of the refrigerant type your system currently uses, the cost, and your options for upgrading systems if that is a more economical long-term option.
AC maintenance is critical to the longevity of your air conditioner. It allows technicians to identify potential problems before they become significant repairs. Small fixes like increasing refrigerant levels and cleaning the evaporator coil during a maintenance call can help you avoid costly emergency breakdowns.
