Summers in northern New Jersey can often be humid and sweltering, so running your air conditioner is necessary for the comfort of your family. However, even the best-maintained system can develop issues that cause your A/C to freeze up.

So, what do you do when your home is suddenly too warm despite the A/C being on – with no cool air coming from the vents or if ice and frost have built up in your air conditioner, rendering it useless? Fortunately, some of these problems are common, easily identified, and fixed.

  • One of the simplest problems that cause an A/C to freeze up is a dirty air filter. This may cause ice to form on your outdoor unit or the pipes running from the compressor. Check and change the filter if it’s dirty and replace or clean it when needed.
  • Check all the air vents or registers to make sure they’re not clogged with dust or lint or blocked by heavy drapes or furniture. Collapsed, blocked, or undersized air ducts, damaged blower motors, or dirt build-up on the evaporator coil can also impede airflow, causing the A/C to freeze up.
  • Turn off the air conditioner at night when the temperature is bearable. Running the unit in cool weather easily causes an A/C to freeze up.
  • Refrigerant leaks or too-low levels can cause pressure drops in the evaporator coil, which allows moist air to freeze and build up on the coil.
  • In humid weather, the air conditioner will condense a lot of the water vapor into a liquid that drains outside or inside, depending on your system. Water build-up in the drip pan beneath the coil can freeze and block the drainage hole.
