“These guys are great, both technically a price-competitively. I have a large house that was built with a oil/hydronic heating system. Five heating zones and combination of in-floor tubing and thin controllable radiators. It is pretty complex. The fuel was from a buried tank outside. It was at the end of its life and I decided to change to a propane boiler system because having a buried oil tank is not a good thing due to possible environmental leaks; also, the price of heating oil had gone way up since installation. I got a number of estimates from other contractors, and was surprised by the cost, and the estimates did not provide enough details. Luckily I somehow bumped into Sprinter. I found that they specialized in hydroinic systems, worked fast, and their estimate was considerably lower than others. They came quickly and solved a number of quirky problems in a short time. After one winter (2025-26) everything is working fine. On top of it all, they found a contractor who dug out and removed the buried tank quickly and for a reasonable price.”
