The latest air conditioning system features variable speed motors that eliminate sounds. If you notice a radiating or loud noise from your air conditioning system, it’s a clear sign of an underlying problem. Fortunately, we asked some of the top air conditioning experts and came up with this guide to what these excessive noises mean.
Most of the time, a radiation noise from your AC system means it’s time to buy a new one. But you can diagnose the issue and develop an affordable solution if you know what these signs mean. Here’s a detailed look into excessive air conditioning noises.
Problems That Cause Excessive AC Noises
Here is a list of AC problems that cause excessive radiating noises.
Lose Parts
If your air conditioning system makes banging noises, it might be the right time to buy a new one. Banging noises indicate a problem with the compressor. You will hear this noise when your HVAC system is reaching the end of its lifespan.
Since the compressor is responsible for distributing refrigerant to different parts of the HVAC system, it’s short-lived. As a result, some internal components get unfastened and cause a banging sound. Because the compressor isn’t easy to dismantle, buying a new HVAC system is better. Even if you try to fix the issue, it’ll cost a lot, and in the end, you’ll have to buy a new HVAC system.
Broken Fan
If your air conditioner is making screeching sounds, it means the fan motor in the outdoor condenser unit is malfunctioning. The air conditioning system in your home has a fan that removes heat from the refrigerant. When this fan is broken or lost, it produces a screeching sound.
The screeching or squealing sound can also indicate a damaged blower fan. This fan is responsible for accumulating hot air from your house and releasing cold air from your AC system. Thankfully, this problem can be fixed by a professional AC repair company.
Defected Contactor Relay Switch
You might notice a humming sound from your AC system. This is because the relay switch is defective. The relay switch is responsible for starting the outdoor condenser unit when it receives a signal from your thermostat. Sometimes, your thermostat is out of battery, and it doesn’t give a signal to the relay switch. However, if your thermostat is working fine, you should get your AC unit inspected by a licensed professional. The relay switch is an electrical problem, and it starts a house fire or causes a short circuit if not fixed.
Refrigerant Leak
If you notice a buzzing sound from your AC unit, you should immediately turn it off and call a licensed AC repair company. The buzzing sound may result from a broken rota blade in the outer condenser unit. However, the main culprit in this issue is refrigerant leakage. Ignoring this problem isn’t an option because it can result in a disastrous situation. Be proactive and check your AC before the summer season starts.
Damaged Electrical Contractor
Sometimes, your outdoor compressor might cause a rattling sound. These sounds might be due to dirt and debris collected in your outdoor unit in the best-case scenario. In the worst case, this problem is due to damaged electrical contractors.
If you have a damaged electrical contractor, you should immediately reach out to your local HVAC repair company and get it fixed. Lingering with this problem can cause severe damage to your condenser, and you might have to buy a new one.
Problems With Thermostat
Your thermostat can be the root cause of many AC problems. One of these is a constant clicking sound. Although it’s normal to hear clicking sounds near the start or end of a cooling cycle, continuous clicking might indicate your thermostat problems. Dismantling and fixing the thermostat isn’t easy. Moreover, if you mess things up, you might need to invest in a new AC system. Therefore, it’s best to contact a professional HVAC repair company.
Malfunctioning Expansion Valves
If you hear a hissing sound from your AC, it is either caused by malfunctioning expansion valves or an air duct leak. Fortunately, this problem has a fix, so you don’t need to buy a new AC system. Call your local HVAC repair company to have them take a look.
