The Most Common AC Issues and How to Fix Them

An air conditioner is a necessity in a home or work environment, and hot days can be unbearable if your AC unit breaks down. So it’s important to be aware of the common air conditioner problems in order to prevent expensive replacements and a complete breakdown.

Let’s take a look at the most common AC issues and how you can solve them.

AC Is Blowing Warm or Hot Air

An air conditioner that is in good working condition should blow cold air. If your unit is blowing warm or hot air, it means you have a dirty filter, low refrigerant levels, dirty evaporator coils, a clogged condensate line, or duct leaks.

Solution

The solution to this problem is to inspect the air filter, ductwork, evaporator coils, and compressor to ensure all these components are in perfect working condition. You’ll also need to check if your thermostat settings are correct. If a dirty filter is the problem, simply replace it and restore your AC unit to good working order. For issues like damaged ductwork, a malfunctioning compressor, refrigerant leaks, and faulty evaporator coils, call experienced HVAC technicians to inspect your air conditioner system and make repairs.

AC Not Turning On

Your AC unit not turning on can arise from broken electrical parts, faulty wiring, a blown fuse, incorrect thermostat settings, or dirty air filters.

Solution

When your AC unit fails to turn on, start by checking if the batteries are in working condition and if the circuit breaker is tripped. If the unit does not turn on after resetting the circuit and changing the batteries, call a professional HVAC company to troubleshoot your air conditioner and make repairs.

AC Running Constantly

It’s normal for an AC unit to run more often during the warmer months, but it should turn off periodically. An AC unit that runs constantly is faulty and needs to be fixed as soon as possible to prevent high electric bills and more damage to your unit. This problem has multiple causes, including filter issues, air flow problems, a dirty evaporator coil, leaking refrigerant, blower and fan issues, or an incorrectly sized unit.

Solution

First, check your thermostat settings to ensure they are correct. You’ll also want to check if there are obstructions that may be interfering with the airflow. If the thermostat, ductwork, and air filter are in good working order, contact an HVAC company to diagnose the problem and provide you with a reliable solution.

Frozen Evaporator Coil

This problem usually occurs when your air conditioning unit is not receiving sufficient airflow to operate normally due to a dirty air filter, an improperly sized filter, a faulty fan, or a dirty evaporator coil.

Solution

If the problem is caused by dirty filters, all you need to do is replace them. For issues like a faulty fan, refrigerant leaks, and leaking ducts, call an experienced HVAC company to diagnose the problem and perform AC repair.

Other common AC problems that you may experience include:

  • Refrigerant leaks
  • Strange smells coming from the AC unit

  • Thermostat malfunctioning

  • Dirty or clogged filter
