A seamless experience from start to finish. Thanks to Audrey for the kind words and for trusting us with your new tankless water heater installation. We’re proud to provide professional service, clear communication, and solutions built to last.
“The Foss staff is always professional. This service was replacement of a 21-year-old tankless water heater with a new, more efficient unit. The staff clearly explained equipment options and prices, and were prompt in scheduling the installation once I decided on my desired product. The installer followed-up with me to confirm his arrival and the work was performed well within the estimated time. A technician followed-up to assure we understood the equipment and scheduled necessary inspections. Very seamless (and painless) process. Nice work Foss!” -Audrey G., Foss customer
