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.

by Nancy H. from Oshawa on Twintech Heating and Cooling

Work was performed in a clean and timely manner. The furnace and metal work was performed by the Twintech team (did not require separate contractor to do the metal work). Energy audit was arranged and promised rebates were received. The overall price was very competitive. We have recommended Twintech to several of our friends and family. Awesome job.

by Syd from Whitby on Twintech Heating and Cooling

Grant and Greg installed a heating and AC system in our new Linwood post and beam home. Post and beam can be challenging structures for running ductwork and their high ceilings and open concept frequently frustrate efforts at balancing air flow and controlling temperatures. But these guys did it and did it right the first time. Even the building inspector was impressed with what he saw. More importantly, the boys brought a high degree of trust and integrity to the job. Something in short supply these days.

by jenner iksmom from Oshawa on Twintech Heating and Cooling

Very polite and professional. They removed my o
ld furnace and A/C and installed my new ones. They were efficient and thoroughly cleaned up when they were done! I would highly recommend them!

I have used Twintech many times over the years. They always arrive quickly and get the issue fixed. The most recent incident was when my air conditioner broke last week I called Greg at 11:30am and he was at my home by 2:30pm he had the unit fixed by 3:30pm. Twintech are very reliable and honest and they are experts in the field. I have already recommended them to many of my friends. I would not use anyone but them for my heating and air conditioning issues.

by Kate A in Pickering on Twintech Heating and Cooling

I would highly recommend these guys, professional, fast and competitive pricing. I moved into this place with no working AC unit with a 8 month baby, he was able to come with in a week to fix even in the busy summer days. He really values his customers , I am already recommending to my neighbors.

by Private User in Whitby on Twintech Heating and Cooling

Very impressed they arrive to quote even though I had forgotten to call them back to confirm date & time. They showed the day before installation to deliver the unit. Returned the next day as promised at 9am. Project was completed in a professional manner. They even fixed a few things that they noticed were not installed correctly, or to code by previous heating & air contractors we had at our residence before. Would recommend this company to everyone!

by Private User from Bowmanville on Twintech Heating and Cooling

Greg removed old oil furnace and oil tank from basement relocated new Napoleon propane furnace to allow duct work to be rerouted to a much more suitable location. Moved air conditioner to the new furnace. Dave recommended two available grants to assist with cost. They kept to their original quoted price which was substantially lower than a competitors for the same furnace and work. They completed the work as stated when stated and left the area clean and tidy. We are very pleased with the outcome.
