SFI Coils

We use our experience as former Carrier salesmen to dig deeper to help you avoid unexpected problems. We often ask "have you thought about this" type questions to make sure your coil is designed correctly for your project. One part of our job is to make you look good! We Are the 39 Series Experts. From 39A to 39M to 39W, and everything in between, we know the specs, and we know the sizes for coils to fit these units. From old replacements to new applications, SFI will make your job easier.
