Customers consistently praise Carl, who multiple reviewers describe as going above and beyond. One homeowner's furnace failed on a Saturday; Carl arrived Monday with a new unit, replaced everything, and even fixed the thermostat. Another customer's boiler failed after three years, and Carl honored the warranty with a brand-new installation the following day. A third reviewer noted Carl treated their home as if it were his own, with prompt, professional work that exceeded expectations.
