Common Air Conditioning Issues and How to Solve Them

Air conditioners are a great way to ensure your home or office stays cool and comfortable during the hot summer. Unfortunately, air conditioners are also prone to many problems that can cause them not to work properly or even break down completely.

This article will provide an overview of some of the most common air conditioner problems and what you can do to fix them. From clogged filters to refrigerant leaks, we’ll cover it all so you can keep your air conditioner running all season smoothly with business HVAC services.

Not Starting

It is unpleasant when you turn on your air conditioner, and nothing happens. This could, among other things, indicate that your thermostat is off, that it is not set correctly, or that the circuit breaker has tripped. It is advised to consult a qualified AC specialist if everything appears in working order but you cannot identify the problem.

Strange Noises

Unusual AC noises are a clue that a serious issue will arise. Regardless of the noise—screeching, clicking, grinding, or rattling—you must speak with a certified HVAC technician to investigate the problem.

Stops Cooling Your Home

Although it has always been loyal to you, your air conditioning isn’t working correctly now. If your home takes too long to cool, look at your maintenance methods. The outer unit usually has this problem, which reduces airflow and performance, when it is neglected and begins to collect dirt.

Filthy or Clogged Filter

A filthy or clogged filter is the root of most AC issues. As a result, you are advised to change the air filter every 30 days. Change your filter regularly to improve your home’s air quality and make your air conditioner last longer.

Faulty Fans

Your outdoor air conditioner can become utterly useless if the fan malfunctions. An inoperable motor, friction caused by a lack of oil, worn-out belts, or sludge are all potential causes of the issue. If there is a delay, the compressor could malfunction, necessitating an AC replacement.

Refrigerated Evaporator Coils

Evaporator coils absorb internal heat and convert it to cold air. If your air conditioner doesn’t get enough air, the evaporator coil will freeze, resulting in either no air entering your home or only heated air. Low refrigerant levels, clogged vents, or a filthy filter could be to blame for the problem.

Rust Is Present

Rust is accelerated by Florida’s hot, sticky weather and the wind off the lake. It indicates a potential issue with your external air conditioning system. Your system’s electrical components will deteriorate due to moisture buildup, which could result in expensive damage and void your warranty.

Dead Compressor

Your air conditioner’s compressor is a crucial component that facilitates air exchange by driving power through the condenser coil on the outer unit. It may be worn out if it won’t start, or the start capacitor may be destroyed.

Duct Leaks

Cooled air doesn’t travel where it ought to when your ducting has holes or other problems. It could leave through the roof or walls. Your system must work harder, making your home appear warmer and increasing energy costs.

Refrigerant Leaks

The compressed gas refrigerant aids in cooling the air that passes through the condenser. Your appliance might eventually leak coolant, which would render it less valuable. The hazardous substance that is spilled can also put your family in danger.


Common air conditioner problems can be quite bothersome. However, they are usually easy to fix. Problems such as a lack of cool air, a frozen evaporator coil, a noisy compressor, or bad odors can all be addressed with commercial AC services. If the issue persists, it may be time to call a professional technician. Remember to regularly service and maintain your air conditioner to ensure it runs efficiently and safely.
