HVAC stands for heating, ventilation, and air conditioning. Even a little defect or dysfunction in the unit has direct effects on each of them. No wonder the smell within your premises – that enters through the ventilation system – is one of the very first and given indicators of an underlying problem.
Let’s see these five toxic smells that points to a much serious issue and what to do next –
Burning or Gunpowder like smell
Electrical or wire-burning like odors usually arise from malfunctioning in the AC fan, compressor, pumps, chipsets, and other wires or electrical components. More often than not, it’s a physical problem that lies much deeper into the system and needs professional intervention for the complete solution.
If left unattended, these are likely to grow and cause disruption to other crucial components of your HVAC system, which will add to the cost latter on. Though, that isn’t the biggest problem. The smell itself can cause many irritations and repository system related problems.
Exhaust fumes or traffic like odor
Your system may or may not be powered by gas. It still contains many toxic and non-toxic gases that help it to run smoothly. If your furnace or utility pipes happen to have a leakage, it may leak into both your ventilation and filter system, giving a motor exhaust or traffic like stink. It won’t be too hard but indicative enough to confirm a problem.
You should not ignore this smell. For it can indicate much greater and horrific underlying problems. The heating system of your HVAC Unit contains toxic gases like carbon monoxide. So don’t wait for another minute and call in a professional as soon as you smell anything like that.
Rotten eggs or sulfur
Unless you have a rotting egg within your house – this smell arises due to an added chemical within carbon monoxide and other toxic gases. These are mostly odorless and this component is added for detection of leakage only.
It should go without saying – you should never ignore this one – even if it’s the mildest. The odorless gas that accompanies the smell is both hazardous for your health and HVAC system – and can cause havoc to your budget.
If the atmosphere smells like new paint or varnish or anything that reminds of a chemist shop or chemical factory, it’s one of the components in your HVAC system that has made it to where it shouldn’t be. The good news is that – it’s not much of a costly problem. Your HVAC expert will be able to diagnose and solve it much sooner than others. The associated health is comparably low as well. So that’s a relief.
Though, that doesn’t mean you should ignore it. It can grow into something gruesome if left unattended. You never know.
Musty, dew-like, or moldy smell
Again, not a serious problem. It’s more of a drainage and cleaning problem.
When your HVAC system runs, it causes the moisture to condense all around the pipes, ducts, plaster, etc. It can sit there for extended periods of time, and if given suitable conditions, can develop into a mold or damp.
This is not much of a serious problem. But if left untreated for a long period of time, the musty air can cause infections and irritation within your repository system.
So once again – better safe than sorry.
