Are you dealing with an A/C unit that won’t turn on or isn’t cooling efficiently? Many of the common problems with air conditioning units can be pinpointed and repaired quickly. Here are 5 warning signs to look out for that suggest your air conditioning may need to be repaired.

Unusual Noises

If your air conditioner is making strange rattling, buzzing or grinding noises, this could be a sign that something is wrong. Unusual noises may indicate that your compressor, fans or belts need to be repaired or replaced. If you notice any of these sounds coming from your unit, it’s important to contact an HVAC technician right away to diagnose the problem and suggest repairs.

Low Air Flow From Vents

Low airflow from the vents in your home is a sign that there may be a problem with the air conditioner. If you turn on your air conditioner and notice that only warm air comes out, it could mean that the compressor is malfunctioning or needs to be replaced. Additionally, if your air conditioner’s blower fan isn’t running efficiently, that could also lead to weak airflow from the vents. In either case, schedule an HVAC service to investigate and repair any component of your system causing low airflow.

Excess Water Around Unit

If you notice any water around your air conditioner, that can be a sign of trouble. If your unit is leaking water, it could indicate a blocked drain line or condensate pump, or that the evaporator coil is damaged or frozen. All of these issues should be examined and repaired by an HVAC technician as soon as possible, to prevent further water damage or loss of efficiency from your air conditioning system.

Poor Air Quality

If the air coming from your air conditioner is not cool or doesn’t feel clean, it could be a sign that your air conditioner requires maintenance. In particular, if you notice dust in your home or smell unpleasant odors when the system is running, then it’s likely there’s something wrong with it. An AC tech can diagnose and repair any issues related to poor airflow or indoor air quality.

Warm or Insufficient Cooling Air Coming From Vents

If there is warm air coming from your air conditioner’s vents, it means that the system is not working properly. Depending on the case, a clogged filter or a faulty compressor may be causing the issue. Additionally, you should also check if certain rooms are hotter than others — this could be a sign of incorrect duct sizing or lack of maintenance. It’s important to address these issues as soon as possible.
