refrigerant leaks

signs of a refrigerant leak

Refrigerant or freon leaks are a common problem in A/C units and are mostly caused by cracks, holes or punctures in the unit's copper coils. Signs you may have a freon leak include:


  • AC not cooling down to the set temperature
  • Hot air is blowing out of your vents
  • Your AC unit is making a hissing sound
  • The evaporator coils are frozen
  • Your electric bill suddenly increases


Using an electronic leak detector or dye, our technicians can perform a leak test to determine where the leak is coming from, and offer suggestions as to the best possible repair for your specific freon leakage problem. Once the leak has been repaired, freon can be topped off to the correct levels to ensure optimum performance of your system.

helpful tip: R22 freon replacement

If you have an air conditioning system installed earlier than 2010, it likely uses R22 refrigerant, which is being phased out by the EPA in 2020 because of the harmful effects on the earth's ozone layer. Because of this, R22 will be available only in limited supplies, and at an inflated cost. However, Denton Heating and A/C can offer substitutes to R22 that are not only safer, but more cost effective as well. Call us for more information today!
