5 Common Reasons for Bad HVAC Smells


Your heating system is subject to all kinds of conditions. When it isn't in use it can collect dust. If maintenance has been performed regularly, it could break down, which means you'll need to call for HVAC repair in Acworth. If your HVAC is emitting a certain smell, you might wonder what the cause is.


Rotten Eggs

The sulfur smell coming from your HVAC system is bad news. Open all your windows, get out of the house and then call the gas company. A natural gas leak is nothing to sneeze at and should be taken care of by a professional.


Getting Gassy

The smell of gas burning isn't necessarily bad if it comes from your vents and it's been a while since you've used your heater. It usually is just the smell of dust getting burned out of the system. However, if the smell is coming from somewhere else in the system, call out a professional to deal with the problem. There could be a fire hazard in your HVAC system.


Electric Ozone

This smell may also be an indication that the system is burning out the dust. However, if it seems like it might be overheating, or the smell lasts longer than about a half hour, turn it off and check the air filter. If the air filter is dirty, replace it. If the air filter is okay, get a professional to check out the problem.


Oil Slick

A new furnace may smell like oil for the first day. Otherwise, you may have an oil leak. Oil leaks may involve tightening a fitting. Otherwise, getting a professional in to look at the oil is going to be your best bet for fixing it safely.


Mold or Mildew

A moldy smell is not only unpleasant, it can create a health hazard. The most common smell that afflicts HVAC systems is from mold or mildew. Mold or mildew build up means that water is getting into the system. While you can still run your HVAC, you want to call in someone who does HVAC repair in Acworth, to repair the problem and ensure it doesn't recur.
