Why We Don’t Install Used Parts in Heating Systems


When it comes to maintaining the comfort of our homes, particularly in the colder months, the reliability of heating systems is paramount. At R&B, we were recently asked (via a 1-star review) why we had not installed a used part in place of the comparatively expensive part that we did use to repair a customer’s heating system. While it’s not a common question or complaint that we receive, in our ethical world of reduce / reuse / recycle it is a valid question even if it’s not a wise choice.  This blog will delve into all the reasons why R&B never installs used parts in heating systems.  While it might seem like a cost-saving measure, there are several compelling reasons to avoid this practice.

Safety Concerns

The foremost reason to steer clear of used parts is safety. Heating systems operate under pressure and high temperatures, which means that any malfunction can pose serious risks. Used parts may have hidden flaws or wear that aren’t immediately visible. Installing these parts could lead to system failures, resulting in potential hazards like gas leaks, carbon monoxide exposure, or even fires.  

Reliability and Performance

I mean if you imagine the reason someone might be selling a used motherboard on eBay, there really aren’t many good reasons that come to mind.  Was it a component in a furnace that was replaced and is being parted out?   Heating systems are designed to operate with specific components that meet certain standards of performance and reliability. Used parts may not deliver the same efficiency or performance as new components. Over time, this can lead to reduced heating capacity, higher energy bills, and more frequent breakdowns. Investing in new parts ensures that your system runs optimally and consistently, maintaining the desired level of comfort in your home.

Warranties and Guarantees

New parts come with warranties, providing peace of mind and protection against defects. When used parts are installed, not only are they without warranty, but any warranty that the original manufacturer provided is likely void. This means that if something goes wrong shortly after installation, the homeowner could be left with the full financial burden of repairs. In contrast, new parts offer the security of knowing that you’re covered should any issues arise.  

R&B has a one-year parts and labour warrant against any defect in the parts installed. That means if the part we replace (an electronic motherboard in this case) doesn’t work as they should within one year, we’ll replace it again for free.  Contrast that with if the used part fails.  In that case, the customer would have to pay all the labour to re& re that same part second time, not to mention they’ll need to find a second used part, or finally purchase a new one.  It seems like a pretty high risk.  

Long-Term Cost Savings

While it may be tempting to save money upfront by using used parts, the long-term costs often outweigh these initial savings. Used parts can lead to inefficiencies, requiring more frequent repairs or even premature system replacements. New parts, while a higher upfront investment, tend to have a longer lifespan and better efficiency, resulting in lower operating costs over time.  The new part will likely last another 10 years.  What’s the lifespan of a used part that’s already 10 years old?  

Compliance with Regulations

In our area, the gas safety branch and licensing regulations may stipulate that certain components in heating systems must be new to ensure compliance with safety and performance standards. Installing used parts may not only lead to unsafe conditions but could also result in other issues or if the system doesn’t meet local regulations. It’s essential to adhere to these codes for both safety and legal reasons.

Potential for Increased Noise and Vibration

Used parts may not fit as snugly or operate as smoothly as new ones. This can lead to increased noise, vibrations, and general wear on other components of the heating system. Over time, these issues can escalate, leading to more significant problems that require costly repairs.  Not a risk with the motherboard, but definitely as risk with anything like a blower motor, impeller, or other moving parts.  

The Final Word

In conclusion, while the allure of saving money by installing used parts in heating systems can be strong, the risks and potential costs far outweigh the benefits. Prioritizing safety, reliability, and long-term efficiency is essential for maintaining a comfortable and secure home.  When you choose R&B, you can expect that we’ll live up to our mission – to offer quality solutions that last.  Investing in new parts not only ensures optimal performance but also provides peace of mind that your heating system will operate safely and efficiently for years to come. When it comes to heating systems, it’s best to go with the new for the sake of safety, reliability, and overall comfort.
