It depends on what’s causing the problem. For instance, your air vents might make noise if you have a dirty air filter. If so, the solution is simple: Replace your filter. In other cases, it could indicate an issue with your ductwork, refrigerant lines, or electrical system. If you’re unsure, it’s best to hire an HVAC professional to check it out.

Areas of your home may provide an ideal environment for green or black mold. Most molds love moisture and will thrive in wet or damp areas. Some types of mold, such as Stachybotrys chartarum, grow well on materials commonly used in homes, such as gypsum board and wood. Mold may also grow in areas where there are leaks, such as in bathrooms, kitchens, or basements.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.
