Five Reasons That Your Central AC Is Not Working

Two people who are sweating in their home.We all enjoy going outside and having fun in the sun with friends and family, but our home should be cool and comfortable. That desire for comfort is why having a high-quality air conditioning system in your home is an excellent investment to make. It is essential to keep up with the maintenance of your central air conditioner and keep an eye out for any changes in its performance. Fortunately, the heating and cooling professionals from Tragar Express are here to provide five possible explanations why your central air conditioner is not working like it used to.

Common Central Air Conditioner Issues

  1. Air Condenser Is Clogged

    If you can turn on your air conditioner but notice that the air is not any cooler after a while, the problem could be your air condenser. states that over time, the condenser can become clogged with dirt and debris. When foreign particles build up in your air condenser, it can become clogged, decreasing the AC unit’s ability to circulate air.

  2. Warm Air Leaks

    If the air conditioner is on and you feel cool air blowing around, but the room is not cooler, there could be hidden cracks. On a summery day, warm air can easily leak into your home if you have open spaces that the air can travel through. This is especially true if the weather stripping seals around your windows and doors aren’t snug, says

  3. Air Filter Is Dirty or Clogged

    Another possible for the room to still be warm despite your central AC being on is your air filter. says if the air filter is dirty and full of dirt, dust, and debris, this will decrease your air conditioner’s operational efficiency. A dirty air filter can block airflow, so your air conditioner will not blow as much cold air as it usually would.

  4. The Thermostat Is Not Calibrated

    If your air conditioner is not cooling your home, states that it may be because of your thermostat. Your thermostat lets your air conditioner know how cool to keep your living space, but it needs correct calibration. An improperly calibrated thermostat will not communicate accurately with the air conditioner, so the temperature you set your air conditioner to will not reflect the temperature you feel. Also, be sure to change your thermostat’s batteries periodically.

  5. Low Refrigerant or a Leaking Unit

    Is the AC still not working? If you have an older central air conditioning unit, check the refrigerant level. The refrigerant in an air conditioner is the main chemical that cools the air produced by the air conditioner, says If the level is low, your air conditioner will not cool your home very effectively. Newer central air units don’t usually need to recharge unless it has developed a leak
