5 Common AC Problems

Are you having trouble with your air conditioning system? Have you been experiencing some strange and unusual issues? This is a common problem for AC systems and can be solved with a number of simple steps.

There are a few common AC problems that are experienced across the board. Knowing what these are can help you solve them yourself. In those cases when you cannot, you are left with only a few possible explanations.

Read on to learn more about common air conditioning problems and how they can be solved.


1. Refrigerant Leak

This often occurs where the refrigerant lines connect to other parts of the system or where small cracks have developed in the lines. It is important to monitor the refrigerant levels on a regular basis and repair any leaks quickly.

If the AC system is low on refrigerant, it will have reduced cooling capacity, resulting in a decrease in the efficiency of the AC unit. A refrigerant leak requires a professional technician to locate and repair the leak and recharge the system with refrigerant.

2. Faulty Capacitor

A capacitor controls the electrical energy flow in an AC and when it fails, it leads to decreased AC efficiency and other issues. The signs of a faulty capacitor include a humming sound, insufficient cooling, tripping off the circuit breaker, and a buzzing noise.

Regular AC maintenance checks by a qualified professional should be carried out to detect any capacitor problems. The technician will inspect and assess the issue and replace the faulty capacitor if needed.

3. Dirty Air Filters

This occurs from the filter not being replaced like it should or from too much dust and debris in the air. This can cause several problems, such as clogging the evaporator coil and blowing warm air. Clogged filters can also cause the cooling system to overwork itself and become noisy.

It’s recommended that air filters be changed every one to three months to keep AC units running efficiently and to avoid problems.

4. Frozen Evaporator Coils

Frozen coils are typically caused by insufficient airflow over the evaporator coils. This results in a buildup of frost and eventual freezing. To prevent this, make sure the air filter is replaced regularly, and the indoor blower motor is working correctly.

Regular maintenance, like coil cleaning, can help prevent future evaporator coil problems from occurring and ensure good indoor air quality.

5. Malfunctioning Thermostat

If your AC unit is having difficulty reaching its set temperature, your thermostat is likely at fault. This can be caused by a lack of AC maintenance, dirty filters, or a malfunctioning blower motor.

An expert technician can quickly diagnose and repair a malfunctioning thermostat. It’s important to ensure the thermostat is calibrated correctly and doesn’t display false temperature readings for your AC unit to be effective.

Tips to Prevent Common AC Problems

Common AC problems can be challenging and costly. Proactive maintenance is key to preventing unexpected AC repairs and headaches.

Talk to a qualified technician if your AC system is not functioning properly. They can diagnose and repair any AC issue, thus keeping you comfortable and cost-effective all summer!
