You count on your HVAC system to keep you comfortable inside your home. However, full comfort can be challenging to achieve when your air conditioner is operating with lots of noise. It’s not uncommon for a sound to escape your unit every now and then, but consistent noises can be a sign of an issue.
Mission Air strives to keep your heating and cooling system in top-tier condition. When a problem arises with one of your units, you can count on our professionals to solve it. Read ahead to learn about your air conditioning system and why it’s running loudly.
Indoor And Outdoor Causes For A Loud AC
When your quiet AC becomes loud out of nowhere, you’ll want to inspect your indoor and outdoor units. For instance, a loud outdoor system may have debris lodged inside it. Foreign objects can get stuck in the fan, causing rattling and banging noises. You can turn the unit off to try and remove any material inside of it.
A noisy indoor unit may have an issue with one of its internal parts, such as the blower motor. Blower motors can wear out over time, creating strange sounds. Additionally, the part may be faulty, or one of the bearings may need lubricant. The machinery can produce strange sounds for various reasons, but a professional can determine the root of the problem.
The wear and tear of parts can also present a problem for your outdoor unit. If you notice loud noises from either of your AC systems, a professional technician can conduct repairs to stop the source of the sound.
Other Noise-Related HVAC Problems
If you can’t find any issues after inspecting your unit, the problem may reside with another component of your HVAC system. You should factor in your other machinery when strange sounds are present.
Leaky Ductwork
Your household ductwork will inevitably experience wear and tear over time. Leaks can form in the material, causing air to escape through any openings. This may produce strange sounds, such as whistling or humming.
Faulty Heat Pump Refrigerant Valve
If your heat pump is hissing, you’ll want to contact an HVAC technician. This problem can indicate a leaking refrigerant valve, which can be dangerous. The coolant contains chemicals that can cause health issues if not corrected.
Signs You Need Professional AC Repair
When your system is in need of repairs, it can be challenging to determine when to call a professional. Strange noises aren’t the only indicators of a problem with the unit. The machinery will show a few warning signs when repairs are needed, some of which are:
- Abnormal odors
- Insufficient airflow
- Short cycling
- Malfunctioning thermostat
- High energy bills
If you notice any of these issues with your AC, this indicates that a problem is present. Your comfort should never be compromised, especially when temperatures begin to rise. An experienced technician can perform the necessary AC repair to get your system operating efficiently again.
