Why Would AC Suddenly Stop Working?
Greg Elder • Jan 27, 2023

Air conditioning is essential in your home, especially during the hot summer. It is therefore vital to ensure that your air conditioning is operating efficiently to keep the hot summer heat out of your home. However, like any other electronic appliance, air conditioner systems are prone to system failure or breakdown.

Nothing is more frustrating than a brokens air conditioner, and there are some common causes of air conditioner failure. Having a prior understanding of the issue at hand can assist you in avoiding unnecessary repairs or premature  AC replacement in Owensboro.

Common Causes For Your AC To Suddenly Stop Working

Fuse or circuit breaker failure

If your AC suddenly stops working, one of the first things you should check is whether a fuse or circuit breaker has blown. This is because electrical problems are one of the most common causes of an AC unit stopping abruptly.

If the circuit breaker has tripped, simply reset it and see if that solves the problem. If you find that a fuse has blown, you’ll need to get it replaced. If neither of these solutions helps, then you’ll need to hire an HVAC professional to investigate further.

Thermostat issues

If your system thermostat fails, your air conditioner may stop working or cycle on and off too frequently, reducing the system’s lifespan, wasting energy, and increasing your electric bill. However, it may be a simple solution.

Before calling professionals to air conditioning repair, replace the thermostat batteries. Check your thermostat settings next. Your thermostat settings may be set incorrectly, which can cause your device to misinterpret your cooling requirements.

If you need to replace your thermostat, take a moment and consider your options. A programmable thermostat will also allow you to program various cooling settings based on your preferences.

Problems with coils

Your air conditioning unit consists of two coils: the condenser coil and the evaporator coil. These coils work together to remove heat from your home. If either of these coils becomes damaged or dirty, it can cause your AC unit to stop working properly.

If you notice that your AC isn’t cooling your home as efficiently as usual, check the coils to see if they need to be cleaned or replaced. This is a fairly easy repair that you can do yourself, but it’s best to consult an HVAC professional if you’re not sure how to proceed.

Low refrigeration

Low refrigerant levels are usually the result of a leak in the refrigerant lines. Leaks prevent your AC system from properly cooling the air, causing the compressor to overheat and eventually fail.

Refilling the AC unit with refrigerant will not solve the problem because the refrigerant will just leak out again. Instead, hire a professional AC technician to fix the source of the problem.

Faulty compressor

Compressors are an essential component of your air conditioner system. As they facilitate the airflow inside your unit, keeping them in good condition should be one of your top priorities as a homeowner.

If your compressor is damaged or malfunctioning, the air conditioner may have difficulty cooling the air. When such a problem arises, it is best to contact professional technicians and have them inspect the system.
