What Stinks? Common Heating System Odours

When your heating system at home is working properly, you will not hear any sound... and you will definitely not smell any foul odour. If yours is giving off an unusual odour, don't panic just yet. It's better to know what it is you smell.


Here are some of the most common heating system odours and what they mean:


Rotten Egg


Natural gas is odourless and gas companies add a chemical to it - causing a rotten egg smell. If what you're smelling is a faint odour, observe for a few hours or a day because it may go away quickly. But if the odour is strong, that could mean a gas leak! Quickly open your windows to get proper ventilation. If possible, shut off the heating system and leave your house. You should also call Twintech Heating & Cooling or the fire department in your area to check it.


Burnt or Smoky


If you are catching the odour of burning plastic or wires, it could mean that there's a material inside your system that is overheating. The smell (hopefully, there's no smoke in sight!) could indicate severe overheating is happening. This can start a fire. Shut your system off until the source of the burning smell is located by an HVAC pro.


Dusty


Are you noticing a dusty smell when you turned your heating system on when you got back from your summer trip? See, dust accumulates on your system's components and they can get hot when your system starts running thus causing the smell. The smell will usually be gone within a few cycles.


Electrical


Similar to the smell of burning material, this odour may also be indicative of overheating. It may also mean there is a problem with the motors, wiring, or other electrical components. It may indicate a pending blower motor failure. The system should be immediately shut down and the problem fixed.


Dead Animal


It is not impossible for small animals like mice to reach your heating system or ductwork and die there. It can cause a very foul odour. Of course, this offensive smell would go away as soon as the dead animal is removed and the spot cleaned.

We are very pleased with the work done by Twintech. They were very professional from start to finish. Dave came to our home and gave us a very competitive quote for new high efficiency furnace and air conditioner. The installers were very courteous and professional. We would highly recommend them.

This review is late coming so my apologies to the amazing Twin Tech team! I contacted Dave at Twin Tech for a quote this past Feb (as I was collecting a few) and his recommendation was excellent. From the first meeting with Dave to the team installing the new furnace, not once did i feel uncomfortable . The team were extremely professional yet personable and clean and tidy. Decent companies still exist!
The new furnace just purrs and its just amazing the difference it has made!
(PS my sibling ended up getting a furnace from them as well)

The service was Twintech was excellent.
Dave our salesperson was easy to talk to and was professional. The unit recommended meets our needs and budget.
Greg and his team arrived on time for the installation and even got rid of the garbage the contractors left in our furnace.
Would definitely recommend Twintech.

Our old water tank was installed in 1997. Wasn't working as well as it should so we looked into a tankless as it is more efficient and a space saver! we had used Twintech in the past for a furnace cleaning and were satisfied with that so we decided to ask for a quote for the changeover. Gary arrived and provided the options and the quote fit within our budget so we decide to go with them after receiving a few alternative quotes from other companies. They did what the said would be done and it was completed within a reasonable time frame! Removal and cleanup of the old tank was seamless. We are now enjoying consistent and efficient Hot water! I recommend Twintech and would use them for future projects!

by New AC Unit + Humidifier on Twintech Heating and Cooling

One of the most honest HVAC companies out there! Dave was very helpful and informative in helping us choose a new AC unit. While they weren’t the lowest quote, we went with them because we trusted Dave and he was the most honest guy out of the companies that quoted us.
Greg and his crew who installed the unit were very professional and did a great job. If I could do it over again I would choose Twintech again.

by Private User on Twintech Heating and Cooling

Relocated and replaced our air conditioning unit. Fast, professional, and high quality service. We would definitely use them again for future projects!
