How to Detect a Hidden Refrigerant Leak in Your AC
How to Detect a Hidden Refrigerant Leak in Your AC A refrigerant leak in your air conditioner isn’t just bad for comfort—it can cause higher energy bills, reduced cooling efficiency, and long-term damage to your system. At Patriot Heating & Cooling LLC, we want Montana homeowners to know the warning signs so you can catch leaks early before they become costly repairs. Why Refrigerant Leaks Are a Problem Refrigerant is the lifeblood of your AC. Without enough of it, your system can’t effectively absorb heat from your home. This leads to overworked components, reduced cooling power, and possible compressor failure. Common Signs of a Hidden Leak Warm Air from Vents If your AC is running but the air feels lukewarm, it could mean refrigerant levels are too low to properly cool your home. Hissing or Bubbling Sounds A faint hiss may indicate refrigerant escaping from a small hole, while bubbling sounds often point to leaks in the evaporator coil. Longer Cooling Cycles A unit that runs constantly without reaching the set temperature may be struggling due to low refrigerant. Frozen Evaporator Coil Ice buildup on the coil is a telltale sign of a refrigerant problem, as low levels cause temperatures in the coil to drop below freezing. Unexplained Energy Bill Spikes If your usage hasn’t changed but your bill has, an inefficient AC due to a leak could be the culprit.
