You’re relaxing in your cool home during a scorcher in Farmington, Arkansas. You’re reading your favorite book when your HVAC system starts making a strange noise, interrupting your pleasant afternoon. Strange noises coming from your HVAC system are certainly cause for concern, but don’t despair. Some noises are perfectly normal, while others might need to be checked out by an HVAC service technician.

Rattling

If your outdoor unit is buzzing or rattling, it might mean that it has debris trapped in the system. If you can still see it sticking out of the unit, you may be able to remove it yourself. Otherwise, leave this task to a professional to prevent injury or damage.

A rattling or buzzing noise may also indicate that you need to change your air filter. If you’ve changed the filter and the problem persists, call a professional. It could be a problem with a fan motor or a broken part. We don’t recommend trying to repair these issues on your own.

Hissing

If you hear a hissing noise coming from your vents, this is likely a sign that air is escaping from the ductwork. This may not seem like a huge problem. But over time, it forces your HVAC system to work harder and adds extra cost to your energy bill. It can be very difficult to locate the point at which air is escaping. Therefore, you should call a professional to find and repair the leak before the problem becomes bigger.

Banging

The worst sound that your HVAC system can make is a clanking or banging noise. This almost always signals that something in your system is broken and in immediate need of attention. If your HVAC is making this kind of sound, call a service technician right away.
