When the scorching heat of summer arrives, there is nothing more refreshing than walking into a cool, air-conditioned space. However, an AC compressor not turning on can quickly turn your oasis into an uncomfortable environment.
Understanding the bad AC compressor symptoms and knowing how to check them are crucial steps in troubleshooting your cooling system. This guide will explore common signs of a faulty AC compressor and provide you with a step-by-step approach to assess its condition.
How To Tell If An AC Compressor Is Bad
Is your AC not cooling your home as it should? One of the common culprits behind a poor air conditioning system is an AC compressor not coming on. Identifying the signs of a bad AC compressor early on can save you from potential discomfort and expensive repairs.
Here are some key symptoms to watch out for and avoid signs you need a new AC unit.
1. Warm Air Blowing
One of the signs of a malfunctioning AC compressor is when warm air is blowing from your vents instead of cool, refreshing air. This suggests that the compressor is not effectively compressing the refrigerant, ruining the cooling process.
2. Unusual Noises
Is your AC unit making strange, loud noises such as clanking, screeching, or grinding sounds? These strange sounds could indicate a worn-out or damaged compressor. They often mean internal issues that require immediate attention.
3. Frequent Cycles
Does your air conditioner frequently cycle on and off within short periods? A failing compressor struggles to maintain consistent cooling, causing the system to overcompensate by frequently turning on and off.
4. Tripped Circuit Breaker
If your unit repeatedly trips the circuit breaker, it may suggest a compressor malfunction. When the compressor draws excessive current due to internal issues, it can cause an overload and trigger the breaker to trip as a safety measure.
5. AC Refrigerant Leak
Look out for oily or greasy substances around the compressor or refrigerant lines, as these can indicate an AC refrigerant leak. Reduced refrigerant levels can ruin cooling efficiency and potentially damage other components.
These are all relatively common signs of a bad compressor besides the home AC compressor not turning on. Beware of them and take action as soon as you identify one!
How To Check An AC Compressor
Before calling a professional HVAC technician, you can perform some preliminary checks to determine if your AC compressor is the root cause of the problem. Follow these steps to assess the condition of your compressor and make your AC more efficient.
- Start with the basics: ensure that your thermostat is set to the cooling mode and set to a temperature lower than the current room temperature. Make sure the AC unit is plugged in and that the circuit breaker has not tripped.
- Power supply check: verify that the power supply to the outdoor unit is intact. Inspect the electrical connections and wiring for any signs of damage or loose connections.
- Capacitor examination: the AC compressor relies on capacitors for starting and running smoothly. Inspect the capacitors for any bulges, leaks, or signs of damage. Faulty capacitors can prevent the compressor from functioning properly.
- Compressor clutch assessment: locate the AC compressor and visually inspect the clutch mechanism. If the clutch is not engaging or the pulley is not spinning, it indicates a potential compressor problem.
