How to Identify the Telltale Signs of a Freon Leak

As the summer months draw nearer, many rely heavily on our air conditioning (AC) units to stay cool and comfortable. Unfortunately, AC units can run into many complications. One common problem that can occur with AC units is a freon leak. Freon leaks can result in various issues affecting your AC's performance and efficiency.

At Harris Aire Serv®, we are experts at handling AC repairs and replacements. If you have a freon leak or issue, contact our team immediately. These tips will hopefully help you recognize signs of freon malfunctions early. By doing so, you may be able to avoid costly emergencies.

What is Freon, anyways?

We rely on air conditioning systems to keep us cool and comfortable during the hot summer months. But have you ever wondered what's inside those AC units that make them work? One of the main components is a type of refrigerant called Freon.

Freon is a trademarked name for a type of chlorofluorocarbon (CFC) refrigerant developed by DuPont in the late 1920s. It is a non-toxic, non-flammable, and odorless gas used as a coolant in air conditioning, refrigeration, and heat pump systems. It became popular because of its efficiency in absorbing and releasing heat energy.

Not all AC units use Freon anymore. Due to concerns about Freon damaging the ozone layer, new regulations are phasing out some Freon-based refrigerants. Recent AC models use more environmentally friendly refrigerants, such as hydrofluorocarbons (HFCs) like R-410A. If you have an older AC unit that uses Freon, consider replacing the refrigerant or upgrading to a new unit.

How does Freon Cool Homes?

When Freon refrigerant is pumped into the AC system, it absorbs heat from the surrounding air and turns it into gas. The warm gas is then moved outside the building and cooled down, condensing back into a liquid. This cycle repeats continuously, allowing the AC unit to cool down a room.

Unfortunately, Freon has a significant downside as it is a greenhouse gas contributing to climate change. One pound of Freon is estimated to have the same greenhouse effect as two tons of carbon dioxide. In addition to environmental concerns, Freon is also dangerous to human health if inhaled at high concentrations.

Commonplace Indicators of Freon Leaks

AC Runs Constantly Without Cooling

If you notice your AC unit running for extended periods without cooling your home, there's a good chance you have a freon leak. This is because your AC relies on refrigerant (usually freon) to absorb heat from your home's air. A leak in the refrigerant line will result in a reduced cooling effect, and your AC will need to run longer to achieve the desired temperature.

Refrigerant Lines Are Frozen

Another common indicator of a freon leak is when the refrigerant lines freeze over. This happens because a leak in the refrigerant line causes the freon to expand too quickly and get too cold, which then causes ice to form on the coils and lines. Look for any ice buildup on the AC unit, especially on the refrigerant lines.

You Notice Bubbling or Hissing Sounds When the Ac Is Off

If you hear any bubbling or hissing sounds when your AC is off, it's a sign of pressure building in the refrigerant line. A leaking refrigerant/freon line can cause your AC to lose pressure, causing weird noises from the unit.

AC Air Emitting from The Vents Isn't Cold

Without enough refrigerant, your AC will be unable to cool the air properly before it's released into your home. If your AC is blowing warm or room-temperature air instead of cool air, it could be due to a freon leak. This is a common issue that requires professional repair.

High energy bills

A freon leak can cause your AC to work harder to cool your home, resulting in higher energy bills. If you notice an increase in your energy bills during the summer months, it could be a sign of something wrong with your AC unit.

Upgrade Your HVAC System or Hire a Pro for Fast Freon Repair

It’s wise to watch for signs of a freon leak. Performing routine maintenance on your AC, such as cleaning the filters and checking for leaks, can help you avoid more severe problems down the road. Remember that freon harms the environment, so it's imperative to have any leaks repaired by licensed professionals who can safely handle and dispose of the refrigerant.
