Can a Broken Furnace Contaminate the Air in Your Home?


A broken furnace can certainly cause an inconvenience, but did you know it can also contaminate the air in your home? A broken furnace can release harmful pollutants into your home, potentially contaminating the air you and your family breathe. These pollutants can lead to a number of health issues, including respiratory infections, headaches, and dizziness.

If you notice your furnace isn’t working properly, have it inspected by a qualified technician as soon as possible. Do not even try to repair the furnace yourself – this could be very dangerous. 

Here, we’ll explore how a broken furnace can impact your home’s air quality and what steps you can take to minimize the risk of contamination. Read on to learn more!

Signs that Indicate a Furnace is Broken 

There are a few signs that might mean a furnace may be broken and release contaminants into the air. If you observe any of these signs, it’s important to contact a professional for repairs:

  1. Strange noises coming from the furnace
  2. Decreased airflow from the furnace vents
  3. Higher than normal energy bills
  4. Frequent pilot light outages
  5. Discolored flames from the furnace

What Can Cause a Furnace to Break

The leading reason for a furnace to break is that it wasn’t maintained properly. Like any mechanical device, a furnace needs regular tune-ups to keep it running properly. When a furnace isn’t serviced on a regular basis, the parts can start to wear out and break down.

Another common cause of furnace problems is dirty filters. The air filters in your furnace are there to trap dirt, dust, and other contaminants before they can enter the air circulation system. However, over time, the filters can become blocked with debris. If you have a gas furnace, then another potential problem is a gas leak. 

How Broken Furnace Affect the Air Quality in Your Home

Your home can suffer greatly from a broken furnace, especially if it affects the air you breathe. When a furnace breaks down, it can release harmful particles into the air that can contaminate your indoor air quality. 

These particles can include dust, dirt, pollen, mold spores, and other allergens that can trigger asthma attacks and other respiratory problems. Additionally, a broken furnace can release carbon monoxide into your home, which is a colorless, odorless gas that can be deadly if inhaled.

How Air Filter Impacts Air Quality

Most people know that a dirty air filter will make your furnace work harder, but few are aware of just how much it impacts the quality of your indoor air. A clean air filter can help remove dust, pollen, and other allergens from the air in your home.

Furthermore, it can help prevent mold spores and other contaminants from circulating through your home. If you have allergies or respiratory problems, changing your furnace filter regularly can help improve your indoor air quality and potentially reduce your symptoms.

What You Can Do if your Furnace Breaks

Fortunately, there are some helpful actions you can take in order to prevent a broken furnace from contaminating the air in your home. First, make sure to change your furnace filter regularly to help trap dust and other allergens. 

Additionally, you can install an air purifier in your home to help remove contaminants from the air. Finally, be sure to have your furnace regularly serviced by a qualified professional to help prevent it from breaking down. Following these steps, you can assure that the air in your home is clean and safe to breathe.

When your furnace isn’t working properly or broken, don’t hesitate to contact a professional for help. With the assistance of a professional, you can get your furnace repaired and improve the air quality in your home.

If you need a company for any plumbing needs please make sure to use Lynne‘s HVAC Winnipeg. Scott was out today to clean our sewer line and he was very professional & had everything back working for us again. It seems tree roots were the cause of our troubles. I would rate Scott and the company both five stars. ⭐️⭐️⭐️⭐️⭐️

From the moment I met Josh I knew I could trust this company. He was very patient and explained everything easily. The team came on time. They worked so hard to get my new AC on my old furnace. It was a challenging job but they stayed positive and never discouraged me. I was so confident they will do a great job and they did not disappoint. They cleaned up everything and it looked perfect. I am now enjoying my cool home. Thank you so much and I feel like I found a family. ❤️

After a really bad experience with a competitor I turned to Lynn’s. Scott was early, clean and professional. He took of his shoes, prepared the area where we has going to work and made sure my carpet didnt get any more dirty then it was (competitor had soiled it). The jobs was tougher than initially thought, but Scott kept working at it and didn’t give up and finally found a solution. I felt the costs was proportionate and I would highly recommend Lynn’s Plumbing and Scott in particular. Give others a pass!

Sucks to be without AC when it is 30 degrees out! Luckily Lynn’s helped us repair our air conditioner unit within hours of it breaking down.
