5 Dangerous Heater Odors [And Their Heater Repairs!]

It’s finally time to turn your heater on one of the first chilly days in Hammond, but to your unpleasant surprise, your heater is giving off some very odd smells. It’s hard to tell where those smells could be coming from, but it’s important to pay attention to them as they could be potentially very dangerous. It’s common for mild smells to come from your heater after turning it on for the first time of the season, but if the smells are strong and persistent, you might have a bigger issue.

You can trust that we’ll come in with our expert knowledge, ready to handle any smells that you may be experiencing. Don’t waste time with these potentially dangerous smells — call us today for professional heater repair!


Burning smells coming from heaters, especially after turning them on for the first time in the season, are normal. When it becomes a problem is when the burning smell lasts for longer than 15 minutes. In Hammond, heaters are rarely used, so it’s very common for the burning smell to happen.

If you’re experiencing the burning smells after your heater has been running for quite some time or at random times, you should call for a professional’s help. The issue with this is that your blower motor may be overheating, or there is an excessive buildup of dust in your ducts that isn’t clearing out. When you can’t get rid of the burning smell coming from your heater, contact a professional heating company as soon as possible to prevent further problems from occurring.


Experiencing a mold or musty smell coming from your heater could be a result of trapped moisture build-up. This moisture begins to smell and creates problems when it seeps into the furnace. You can try to get rid of this smell by turning up the heat and letting the smell dissipate, but if it persists, you’ll want to contact a professional.

Gas/Rotten Eggs

If you’re smelling a strong odor of gas or rotten eggs, you could be experiencing a natural gas leak. It’s important to have your system checked when you’re experiencing these smells because it could be caused by a variety of issues. We recommend that if you’re smelling the strong scent of rotten eggs, immediately turn off your heater and leave the area.

This gas leak could become dangerous and needs to be inspected by a professional gas company to ensure that you’re not in immediate danger. Natural gas is very commonly used in homes to power different appliances. Knowing where the leak may be coming from and the potential threat it poses is essential in ensuring your home’s safety and the safety of everyone else in it.

Car Exhaust

If you’re smelling an odor that smells very much like car exhaust, there could be a problem with the ventilation of your furnace. You could be experiencing something like leaking refrigerant, melting plastic or other dangerous issues that can cause damage to your health. Considering that your furnace or heater never uses fuel to produce exhaust, the smell of it is a sure sign that your system is not okay.


Dust accumulation can cause other odd smells that we’ve already noted above, but it’s also possible to simply smell the dust. These simple smells usually come from a clogged filter that has accumulated too much dust to let the air properly flow through. This can lead to dusty air quality that can negatively affect your health.

The HVAC System stopped when my Generator quit. When restarting the generator, the AC did not restart. Manuel came out, checked the entire system & got it working in 20 minutes. He was brilliant, professional & very courteous. I’ve use this company for over 25 years & have always been completely satisfied with their service.
