- AHAnn H.Verified BuyerReviewingSquare D FA36100 - 100A 3 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars8/22/26Professional Service
So far, so good! The circuit breaker was installed along with a new compressor for our church AC, and everything is now working well.
The company has been professional, dependable, and reputable throughout the process. I had a question after the installation, and it was answered immediately. I also appreciated that they followed up and asked for feedback to make sure the new part was working properly and that we were satisfied with the service.
It’s refreshing to deal with a company that not only has quality products but also cares about its customers after the job is completed. I would definitely recommend them!
