Customer experiences documented in reviews reveal significant concerns. One reviewer, Shailendra Pal, described multiple issues following boiler installation including thermostat malfunctions requiring a separate company to repair, a damaged dryer, oil spills left at the job site, and improperly installed plumbing. This reviewer also states the contractor never returned to service the boiler despite holding a five-year service contract.
