I preferred an igniter that I could install myself, which would save me time and money. Understanding the installation process beforehand helped me gauge whether I could handle it.

Reviewing Customer Feedback

Reading customer reviews was invaluable for me. I sought feedback from other users who had purchased the same igniter. Their experiences provided insights into the igniter’s reliability, performance, and any potential issues I might encounter. This step allowed me to make a more informed decision.

Comparing Prices and Warranty Options

Finally, I compared prices from various retailers to ensure I was getting a fair deal. I also looked into the warranty options offered with the igniter. A good warranty can provide peace of mind, indicating that the manufacturer stands behind their product. I wanted to ensure that if any issues arose, I would be covered.

Making My Decision

After considering all these factors, I felt more confident in my ability to choose the right AO Smith water heater igniter.
