It’s great to have all of the important equipment in your home that helps keep it running smoothly, working the way that it should; when it begins to not work as effectively as designed, it’s time to give your Ottawa HVAC professional a call, because a thorough inspection and a plan for moving forward can help get you back on track.

One way to know that your HVAC equipment may not be working how it should be is through the sounds that it makes; equipment that is running efficiently will rarely make loud or strange noises. Here are some important sounds to be mindful of:

Rattling

Hearing a rattling noise coming from your HVAC system could mean a few things. If it originates from the outdoor unit, chances are you have some kind of debris in the system, such as a twig. (While the grate will protect your system from most large debris, it’s still possible for small things to get through). If the rattling seems to be internal, from a furnace or other internal component, turn the system off and call your HVAC technician since removing the obstacle isn’t as simple.

Hissing

Hearing a hissing noise most likely means air is escaping from your system. If the noise is coming from the walls, there’s a good chance your ducts are leaking. Not only can this cause noise, it also wastes money because the air that should be circulating throughout your home is leaking into the walls. Typically when you hear this noise it is because your filter is not “set” right or you have the wrong size filter which is creating the gap in the seal. If this is the case, the air is squeezing past the filter or around it, instead of being pulled through it.

Clanking

An HVAC system that is running normally will make a humming noise. But if it’s clanking, that’s a sign that something is wrong. It could be loose parts, such as the blower motor fan, loose blades, or loose pipes that are rubbing together. Clanking noises are a bit more serious because  loose parts, if not addressed, can cause costly damage to your system.’ (Will Housh, hvac.com)
