6 Common AC Problems That Homeowners Deal With

Wondering if your air conditioner needs fixing?

Air conditioning malfunctions can be inconvenient and even dangerous if you’re stuck in a hot home. Fortunately, most problems aren’t serious–but they can still drive you crazy.

Keep reading to learn all about common AC problems. Then, find out how to fix them.

  1. Excessive Noise

Excessive noise is one of the common AC problems that homeowners can face. Frequent or loud noises can occur due to an issue with the unit’s compressor or indoor fan motor. It can also occur when a unit is in need of maintenance or is overworked. If the exterior of the home AC unit is pitted or covered in dirt and debris, it can cause additional noise.

Another cause of loud AC noise is insufficient airflow, which can be caused by clogged or dirty air filters or blocked ducts. The best way to avoid excessive noise due to AC problems is to properly maintain the unit.

This involves regularly cleaning and replacing parts, inspecting the fans and motors, replacing air filters, and keeping the exterior of the unit free from dirt and debris.

If a homeowner contacts a professional AC technician when excessive noise occurs, the problem can be quickly and properly diagnosed to prevent further damage.

  1. Refrigerant Leaks

Refrigerant leaks in air conditioning systems are one of the most common AC problems homeowners deal with. Refrigerant plays a very important role in the efficiency of the system, and if it is leaking, the air conditioning system is not working as efficiently as it should be.

The symptoms of a refrigerant leak are warm air coming out of the vents and a decrease in cooling power. If you see these symptoms, contact a professional HVAC technician to assess the system.

The technician will check for leaking parts and fix them or advise you to replace the entire unit. The technician will also recharge the system with coolant if necessary.

Having a regular maintenance check-up for your AC system is a good way to avert refrigerant leaks and other common AC problems.

  1. Overheating Issues

Overheating is one of the most common AC problems homeowners have to face. If your AC overheats, it could be because it’s low on refrigerant, has an airflow obstruction or the cooling coils are worn out.

Other causes of overheating can include dirty air filters, a malfunctioning reversing valve (for heat pumps), a compressor malfunction, or a malfunctioning thermostat. Sometimes the problem can be a combination of issues.

To fix an overheating AC, start by checking the air filter and coils, followed by the reversing valve or thermostat. You can then check for leaks in the system and recharge the refrigerant if necessary.

If the problem persists, you should consult a professional HVAC technician to assess and fix the issue.

  1. Poor Air Flow

Poor airflow can be a big problem when it comes to air conditioning. Homeowners will often notice a difference in air flow, meaning the air will not be distributed as evenly as they expect.

Additional symptoms of poor airflow include weak air vents with little to no airflow, loud noises coming from the AC unit, or temperatures not changing even after adjusting the thermostat.

This could be caused by a variety of issues, including a clogged filter, blocked ducts, a malfunctioning fan, or an incorrect thermostat setting. Also, outdated air conditioning units may not have the capacity to move air around quickly and efficiently.

Checking the air filter, ducts, fan, and thermostat are the first steps any homeowner should take to diagnose the situation. If the problem persists, then a further inspection from a qualified HVAC professional should be sought out.

By assessing the cause of the problem, the technician can recommend the best solution for a timely and effective remedy.

  1. AC Thermostat Problems

Homeowners often deal with air conditioner thermostat problems. This can happen in any type of system, whether it be a window unit, central, or ductless split.

A malfunctioning AC thermostat can cause the unit to fail to turn on, malfunction, or freeze up due to a lack of airflow. Other common problems include readings that don’t accurately represent the temperature, and leaving home either too warm or too cold.

Troubleshooters may need to replace the thermostat, the battery powering it, or the switch allowing the unit to run. If a unit runs constantly, it can be an issue with the thermostat’s sensitivity to temperature or the wiring of the unit itself.

Homeowners should attend to these problems quickly as an improperly functioning thermostat can lead to greater energy consumption and bigger bills. Investing in regular maintenance and taking preemptive steps can help ensure smooth functioning and save on replacement costs down the line.

  1. AC Fan Failure

AC fan failure is a common problem for homeowners. The fan, which pulls cool air in from the outside and blows it through your air conditioning system, can wear down and stop working correctly.

Other common causes of AC fan failure include improperly functioning fans, worn-out bearings, clogged filters, and faulty motors. Accumulated dirt, dust, and grime in the system can also lead to decreased efficiency and premature fan failure.

If your AC fan stops working, it’s important to have it inspected by a professional AC technician as soon as possible before damage occurs to other parts of the system. A technician can inspect your fan, diagnose the issue, and recommend a repair solution.

It’s important to invest in regular maintenance and filter changes, as these will help prevent AC fan failure. And since the weather is changing, consider this HVAC cleaning checklist for spring prepared for you.
