Rating 4, 8 (10, 17) · When it comes to your HVAC system, it's important to be aware of any potential noises that could be a sign that it's time to replace it. Loose components can cause a humming or rattling sound from the air conditioner due to vibration. This could mean that the compressor is failing, a pulley has faulty bearings, or a worn-out compressor clutch. Any of these issues should be addressed by an HVAC technician.
To fix the noises coming from the air conditioner, turn off the system and call a professional for repair. The technician will replace any fan blades in poor condition and help the air conditioner to work more efficiently, consuming less energy each cycle. If there is a loud noise coming from inside the unit, it could be due to a broken fan motor or an imbalance in the motor, which could cause an explosion. Replacing the motor will also be expensive, so contact a specialist to better understand the situation.
The life expectancy of HVAC systems varies depending on the type of unit, where you live, and how often you perform HVAC inspections. With regular maintenance approximately every year, an HVAC technician will inspect your entire HVAC system. If there are any problems, they may emit several different noises that may indicate that the operating time of the air conditioning systems is limited. An HVAC specialist will be best able to determine the exact cause and decide if you should opt for repair or replacement.
Continue with regular maintenance until your next HVAC check, which should be done annually to lubricate as needed and replace worn parts and, in general, to ensure that all parts continue to work as they should.
