A professional HVAC technician can often diagnose an HVAC problem simply by its sound. When a homeowner hears an odd noise they will often ask the homeowner to describe the noise to get an idea what the problem is and if their services are needed. GA HVAC Experts will share some of the common noises the HVAC system will make when there is a problem and share what may be causing the noises. A healthy HVAC system will make very little and sometimes, no noise at all. A slight hum is all that a homeowner should ever hear. If other noises develop, the new noise often points to a problem in the HVAC system. Following are some of the common noises an HVAC system will make when it is in distress and what may be causing the noises.
Hissing Sound from AC Unit
When you are hearing a hissing noise it can be caused by a number of problems. Hissing can be causes by a clogged air filter. The hissing from a dirty air filter is due to air flow restriction. Luckily, this problem can be easily fixed by changing the air filters. However, hissing can also be a refrigerant leak. Accompanied with hissing, you may even notice the home feels warmer than normal. A refrigerant leak must be repaired and then the refrigerant refilled by an HVAC technician. If the hissing isn’t due to dirty air filters then contact an HVAC professional.
AC Making Squealing or Screeching Noise
When you hear a screeching or screaming, like the poor HVAC system is in pain, this can be either a loose fan blade or a worn blower belt. When a fan blade is loose it can rub up against the inside of the of the condenser which will sound like screeching. When the blower motor’s belt is worn out, the motor will try to turn. Without a proper belt it can make that screeching noise. Both problems will demand an HVAC technician to repair this problem.
Air Vent Making Rattling Noise
When you are hearing a rattling sound know that this is never good and you need to turn off the HVAC system right away. Rattling can be due to a loose screw or component inside the HVAC system and is bouncing around inside. Another possible problem is a loose air duct section and is leaking out all of the cool or heated air. When you hear a rattling noise, the HVAC system will need to be inspected for loose components. The air duct system will also need to be inspected and repaired.
Air Conditioner Making Loud Buzzing Noise
When there is a buzzing or also described as a humming sound, it most likely is an electrical problem. An electrical problem must be looked at by an HVAC professional. Electrical problems can be risky to DIY. To ensure safety it is best to have the problem inspected by a professional.
