Identifying Faulty or Failing Sensors in Your AC

The sensor is a key component of your AC system that helps regulate indoor temperature. Recognizing the first signs of sensor trouble is crucial to prevent further damage or costly repairs. Read on to learn more about the signs of a faulty sensor and the common causes of this problem. 

Common Indications of a Faulty or Failing Sensor

Your AC system is a complex piece of machinery made with intricate parts. However, the sensors hold a special place. They efficiently monitor the temperature and direct the airflow. Sensors also ensure the humidity level stays within a comfortable range. To find out if you have a faulty or failing AC sensor, there are a few telltale signs that you should look out for.

Inaccurate Temperature Readings

One of the most noticeable indications of a faulty sensor is inaccurate temperature readings. These can cause your AC to fail at cooling your home, leading to discomfort and frustration. The thermostat connected to your AC system may display the incorrect temperature. This makes it difficult to determine how well your system is functioning.

Frequent Cycling

Another sign of a failing sensor is frequent cycling. This is when your AC system turns on and off more than necessary throughout the day. This failure to maintain a consistent temperature can put undue strain on your system. Left unaddressed, this can lead to potential damage and the need for costly repairs.

Unresponsive Thermostat

A faulty sensor can cause challenges in adjusting your thermostat settings. In some cases, the thermostat does not respond to changes in temperature. An unresponsive thermostat can make it difficult to create a comfortable environment in your home.

High Energy Bills

A malfunctioning sensor can impact your energy bills. A faulty sensor can leave your AC system unable to maintain your desired temperature. As such, the system consumes more energy, ultimately resulting in higher bills. If you’ve noticed a sudden spike in your energy costs, it may be time to call for a professional air conditioning service.

Strange or Unusual Noises From the AC Unit

Another symptom of a failing sensor is strange or unusual noises from your AC unit. This disruption is often caused by loose or broken parts in your AC system. If you’ve noticed any changes in the sound of your AC system, it’s best to have it inspected by a professional.

Common Sensor Issues

Certain sensor-specific issues can disrupt your AC system’s performance and  your home’s overall comfort. Below are some common sensor problems.

Misplaced Temperature Sensor

The temperature sensor is responsible for monitoring the heat levels in your home. If it is misplaced, it can cause your system to cycle erratically. This can result in poor temperature control and uncomfortable conditions.

Faulty Airflow Sensor

The airflow sensor ensures optimal temperature control in your home by detecting the condition of the evaporator coil. If it is malfunctioning, it can result in the air conditioner freezing or overheating.

Malfunctioning Humidity Sensor

The humidity sensor is responsible for monitoring the humidity levels in your home. If it is not working properly, it can lead to uncomfortable air that is either too dry or damp. If you’re noticing a stuffy or musty smell coming from your AC system, this may be the cause.

Reasons for Faulty or Failing Sensors

There are several reasons why your AC system’s sensor may be faulty or failing.

Age and Wear

As with most appliances and technologies, age can play a significant role in the functionality of your AC sensor. Older systems are more prone to sensor issues due to wear and tear on the components. Over time, the sensitivity of the sensor may also diminish.

Dust and Debris

A dirty sensor can struggle to accurately detect temperature. This results in fluctuating thermostat readings and compromised performance. Regularly cleaning and maintaining your AC system can help prevent dirt buildup.

Damage or Corrosion

Physical damage or corrosion can also cause sensor malfunctions. This could be due to an accidental impact or exposure to moisture or chemicals. Damage to the sensor components can hinder their ability to function correctly. Regular AC inspections by professionals can help detect such issues early on and prevent further damage.

Importance of Professional Air Conditioning Service

While DIY troubleshooting can help you understand what’s wrong with your AC, fixing a sensor requires professional expertise. With a professional repair service, you can ensure the following:

Proper Diagnosis of Sensor Issues

Professional technicians possess expert knowledge to diagnose sensor problems accurately. They’re better equipped to identify the root cause of the issue. As such, they can implement the most effective and efficient fix.

Safe and Efficient Repairs

HVAC repair professionals have the proper tools and knowledge to safely and efficiently address sensor issues. They understand the necessary safety precautions and procedures, preventing accidents and injuries while doing the job. 

Prevention of Further Damage

Promptly addressing sensor issues can help prevent further damage to your AC system. Early detection and repair can save you from more significant expenses. They can also help you avoid the need for replacing your entire AC system.

Preventive Measures to Preserve Sensors

Regular cleaning can keep dust and debris from damaging your AC’s sensors. Shielding your outdoor unit from weather elements can help preserve sensor integrity too. If your AC system is old, consider upgrading to a unit with advanced sensor technologies that will perform better and last longer.

In addition, routine maintenance of your AC is essential to prevent sensor failures. Certified technicians have the skills to identify potential problems early on. This helps prevent unexpected breakdowns. It’s also a way to save on costs by enhancing your AC’s efficiency and extending its lifespan.

Finding a Reliable Air Conditioning Service Provider

When you search for “air conditioning repair near me” online, specifically look for a service provider that can deliver quality workmanship and excellent customer service. Make sure their service is backed by experience and expertise in AC repairs. Furthermore, consider hiring local technicians as they can respond more quickly to your repair needs. Inquire about their qualifications and certifications, and take the time to read reviews and testimonials from previous customers. This will help you gain insight into the company’s reputation and quality of work. Make sure they charge reasonable fees too.
