What Happens if Your HVAC Unit Springs a Refrigerant Leak?

Spring is here, and warmer temperatures may have you thinking about shorts, sandals, rum punch, gardening or siting by the pool. The last think you want when you head inside to cool off is to discover your central air conditioning isn’t working.

A coolant leak is the main cause of an air conditioning malfunction. In order to cool your home, your air conditioning system must have coolant running through refrigerant lines. Systems installed after 2010 use a product called R410A (brand name, Puron, developed to be more environmentally sensitive and consumer-safe), while older systems (pre-2010) may still be running on a phased-out product, R22 (marketed as Freon). The coolant converts gas to liquid and back, pulling the heat in the air from inside to outside. If refrigerant is leaking or has leaked out, the air conditioning system will not work and can result in a burned-out compressor.

Refilling air conditioning coolant should not be routine
It is not normal for your air conditioning contractor to have to refill the coolant; lower levels indicate a leak somewhere, typically through pinhole punctures in your central air conditioning system. Other causes may be a factory defect that went undetected, poor installation, or corrosion of the system’s metal from formic acid.

It’s not only inconvenient and uncomfortable but dangerous when a coolant leak occurs, as the gas is meant to stay inside the closed HVAC system—not circulate through your home’s airflow.

Signs that the coolant is leaking or has completely leaked out are:

  1. Oily residue at connection points
  2. Worn or rusted parts of the unit
  3. Ice forming on the coils
  4. Higher-than-usual electric bills
  5. Higher-than-usual indoor humidity
  6. Air conditioning not cooling as well or not at all, warm air comes out of the registers
  7. A hissing sound is audible

Beware of contact with coolant
Beyond trouble for your HVAC system, coming in contact with leaking refrigerant can cause a number of physical symptoms to humans.

  1. Dizziness or shortness of breath from breathing the fumes
  2. Irritation of eyes, ears, and throat
  3. Frostbite-like symptoms if the substance gets on your skin
