5 Warning Signs That It’s Time to Clean Your Furnace

A furnace is a jam-packed piece of equipment that needs to be cleaned regularly. Filth and grime buildup in your furnace might eventually cause it to break down and can even present a risk to your safety.

It can be challenging to determine whether or not there has been a change in your furnace’s operation. If you have any doubts about whether or not it’s time to clean your furnace, read on to learn the five warning indicators it’s time to clean it.

1. Making Strange Noises

If you hear the rattling or clanging sound, it is typically the result of pieces in the furnace that have become loose. These components can suffer from wear and tear over time, eventually leading to failure. Dirt and debris may be what is causing these pieces to become loose, and thorough cleaning will assist in eliminating these. 

2. Not Heating Your Home Evenly

If your home isn’t heating evenly, your furnace needs a good cleaning. When furnaces get dirty, they don’t operate as efficiently and can’t heat your home evenly. It results in hot and cold spots and can cause your furnace to overwork and break down.

A professional furnace cleaning from Legacy Heating and Cooling will remove all the dirt, dust, and debris that builds up that causes this to happen. Having your furnace serviced regularly is also essential to keep it in good working condition.

3. Using More Energy Than Usual

Your furnace works hard to keep your home warm during the winter. When dirt and dust build-up on the furnace’s heat exchanger, it has to work harder to heat your home, which uses more energy. 

A clean furnace is more efficient, so it will use less energy and save you money on your energy bills. That’s why it’s essential to have your furnace cleaned regularly.

4. Longer Heating Times

As the weather gets colder, we rely on our furnaces to keep us warm. But did you know that if your furnace takes longer to heat up, it may indicate that it needs a good cleaning? 

A furnace works by circulating warm air through a system of ducts. Over time, these ducts can become clogged with dust and debris, which can reduce the efficiency of your furnace and cause it to take longer to heat your home.

5. Unusual Smells Coming From the Furnace

If your furnace is running and you smell rubber, smoke, or oil, it indicates that it needs a good service. Depending on the severity of the smell, you may need to call in a professional to clean your furnace. A potentially hazardous situation could arise if these odours are allowed to persist without being cleaned.


For your furnace to function correctly, it is essential to identify the indicators that need a thorough cleaning. You may save money on energy costs and ensure that your furnace will continue functioning correctly for many years if you familiarize yourself with these indicators.
