5 Signs Your Furnace Needs a Tune-Up


The days are numbered when running into problems with your home’s furnace. Cold winters demand a lot from our furnaces, which can stress equipment and cause a disruption in your comfort. As the backbone of your home’s heating system, your furnace plays a crucial role in keeping you warm and comfortable; however, like any mechanical system, furnaces can experience wear and tear over time.

In this blog, we’ll discuss five signs that indicate the need for heating repair in the Mission, BC and why you should stay on top of regular maintenance.

1. Weird Noises or Loud Operation

One of the first signs that your furnace may need a tune-up is if it starts making strange noises or operates loudly during a run cycle. These noises can include banging, rattling, squealing, or grinding sounds. These sounds could indicate loose components, worn-out belts, or a malfunctioning blower motor. 

2. Noticeable Changes in Air Quality

If you notice a decline in indoor air quality, such as increased dust, debris, or allergens circulating in your home, it could be a sign that your furnace needs attention. A dirty or clogged furnace filter can restrict airflow and allow contaminants to recirculate, leading to poor air quality. During a tune-up, the technician will inspect and clean or replace the filter, improving air circulation and quality.

3. Increased Utility Bill

Have you noticed an unexpected spike in your energy bills despite not asking for anything more of your furnace than normal? This could be due to an inefficient or malfunctioning furnace. Over time, wear and tear can cause your furnace to work harder to maintain the desired temperature, leading to higher energy consumption and increased utility costs. A tune-up can optimize your furnace’s performance, improve energy efficiency, and lower your heating bills.

4. Funky Odors from the System

Strange or foul odors emanating from your furnace can cause concern. These odors range from a musty smell (indicating mold or mildew growth) to a burning odor (suggesting overheating components or electrical issues). Ignoring these odors can lead to safety hazards and system damage. 

5. Uneven Heating Throughout the Home

Do you notice that certain areas of your home are consistently colder or warmer than others? Uneven heating can indicate airflow problems, duct obstructions, or issues with the furnace’s heating elements. A furnace tune-up will involve checking and adjusting airflow, inspecting ductwork for blockages, and ensuring that all heating components are functioning correctly.
