When your air conditioning suddenly struggles to keep up during a hot summer day in Lewiston, there’s a good chance a refrigerant leak is to blame. Refrigerant is what moves heat out of your home, keeping the indoor temperature cool and comfortable. If the refrigerant level drops because of a leak, the system can’t do its job properly. This leads to warm air blowing from the vents, longer cooling cycles, and more wear on the unit. When left alone, even a small leak can spiral into expensive repair needs or full system failure.
Addressing a refrigerant leak quickly helps prevent unnecessary stress on the system and protects your comfort through the hottest months. Refrigerant doesn’t get used up like fuel does. It should last the lifetime of the AC if no leaks exist. That’s why noticing the warning signs and knowing what leads to these problems can make a major difference for homeowners. The more you understand about leaks, the better prepared you’ll be to respond when something feels off with your AC.
Common Causes Of AC Refrigerant Leaks
Refrigerant leaks often start small and go unnoticed until they cause serious problems for your indoor cooling. Different issues within an AC unit can cause leaks, often tied to wear over time or issues during installation. Here are the most common causes:
– Damaged connections and joints: Over time, vibration from normal operation can wear down joints and connections inside the system. These weak points can slowly start leaking refrigerant.
– Corrosion: Moisture can build up around parts of the AC system and cause rust or corrosion. When parts like the coil walls or copper lines corrode, small holes may form and lead to leaks.
– Improper installation: If the refrigerant lines weren’t connected or sealed properly during installation, problems may surface later. These leaks can appear months or even years after the install.
– Factory defects: While rare, some systems experience leaks due to faulty components that developed during manufacturing.
Refrigerant leaks won’t fix themselves, no matter how small. The longer the system continues to operate with low refrigerant, the more strain it places on the compressor and other components. That strain shortens the life of the equipment and increases the odds of needing major repairs.
Signs Your AC Might Have A Refrigerant Leak
In Lewiston, hot and humid days are common during the summer, making it easy to tell when your AC isn’t doing its job. Often, refrigerant leaks affect the temperature and airflow in noticeable ways. Homeowners should stay alert for common signs like:
– Lukewarm air coming from the vents, even when the thermostat is set low
– Ice forming on the copper lines or coils inside the indoor unit
– Hissing or bubbling noises around the unit, which can come from escaping refrigerant
– A rising monthly energy bill, with no change in daily habits
Take one example: A homeowner notices their AC is still running, but the house hasn’t cooled down after hours of operation. They check the vents and feel lukewarm air. Over the next few days, the air becomes warmer, and the outside unit starts making a soft hissing sound. These are clear signs that a refrigerant leak may be present. Acting fast in this situation can prevent the system from burning out or freezing up.
Ignoring these red flags allows the issue to get worse, forcing the system to work overtime and putting its internal components at risk. Catching these signs early is the best way to make sure the repair process stays manageable instead of becoming a larger headache down the road.
Steps To Take When You Suspect A Refrigerant Leak
Once you suspect your AC has a refrigerant leak, the first thing to do is avoid running it. Allowing the unit to operate with low refrigerant can put serious pressure on the compressor. That’s one of the most expensive components to replace, and keeping the system off can help avoid making things worse.
Here’s what homeowners in Lewiston should do next if they think there might be a leak:
1. Turn the AC system off immediately to stop further damage.
2. Schedule an inspection with trained professionals to pinpoint the source.
3. Let experienced technicians perform the leak test and make repairs.
4. Ask about routine maintenance options to reduce future problems.
Avoid trying to patch or recharge the refrigerant lines yourself. AC systems are high-pressure systems that require specific knowledge and tools to repair safely. Our professionals use approved diagnostic equipment to locate hidden leaks and perform repairs that meet current safety and quality standards. Catching the issue early and having it properly addressed can save you from a more costly breakdown the longer you wait.
How Our Professionals Solve AC Refrigerant Leaks In Lewiston
When a technician arrives to inspect a suspected refrigerant leak, the first step is to complete a full system check. This includes checking both indoor and outdoor components, testing pressures, and using electronic leak detectors or dye tests depending on the situation.
After confirming a leak, the next step is to isolate the faulty component. Common spots include coils, flare fittings, and areas of corrosion. Once the problem location is found, the technician repairs or replaces the affected part. If necessary, the system is evacuated of remaining refrigerant, sealed, and then recharged with the proper amount under manufacturer standards.
Working with certified professionals ensures the issue is fully resolved and not just temporarily masked. Our technicians are trained to spot additional issues that may arise from long-term leaking such as moisture contamination or compressor damage. This approach prevents repeat problems and helps keep your home comfortable longer.
Keeping Your AC System In Top Condition
Preventing refrigerant leaks in the future comes down to regular system upkeep. Just like any other machine, your AC system performs better with ongoing maintenance. This helps catch parts that are starting to wear down before they can cause damage to other components.
Here are a few ways to protect your cooling system long-term:
– Schedule seasonal checkups to inspect refrigerant levels and check for early signs of leaks.
– Make sure the outdoor unit has good airflow and clearance from plants or debris.
– Keep indoor air filters clean to reduce buildup inside the unit.
– Ask your technician to check pressure balances and line integrity during regular service visits.
Homeowners who have their systems maintained ahead of the summer cooling season in Lewiston generally experience fewer issues when the heat hits. Regular inspections reduce the chances of a mid-season breakdown and help the AC unit last longer by addressing strain early on.
Restoring Comfort In Your Lewiston Home
Staying cool in Lewiston’s hot summer months depends on an air conditioning system that runs properly. When that comfort gets interrupted due to a refrigerant leak, it not only creates stress but can also lead to bigger problems if left untreated.
