ckSmithSuperior

ckSmithSuperior is a Worcester heating, cooling and fuel-delivery company with 1,360 Google ratings averaging 4.9. A recent Google reviewer said that after calling one morning with no hot water, the company sent Stanley out the same day to look at the boiler, and he replaced the parts it needed and explained the system. The company's website says it has served Central Massachusetts since 1893 with HVAC, fuel delivery and water-heater services. BBB lists it as accredited with an A+ grade. One recent reviewer said technician Bill found why the heating had failed the previous winter and was putting in a ticket to have it resolved; that customer said Superior had come out that winter and got the system to "work" but missed the actual problem. A recent customer who had mini splits installed said the team arrived on time and completed the work sooner than expected. A recent reviewer whose furnace was cleaned by a technician named Bill said he found a few things to be repaired because of Grafton water. A recent customer said they have relied on the company to keep oil in the tank and the furnace running since 2017. A 2026 reviewer said technician Will arrived promptly after a late-night call to the emergency line on a cold Friday when the heat stopped working, and that he had the part needed and swapped it out. A 2025 reviewer whose old boiler was making an unusual sound said technician David called with an ETA, arrived early, diagnosed the problem, replaced the nozzle and was gone within a half hour. A 2023 r/WorcesterMA commenter wrote of getting a 0% Mass Save loan to replace a boiler and oil tank through CKSmith Superior. A 2017 Angi reviewer described a new oil burner and hot water heater installed by Chet and Joe, with Alex handling the scheduling, financing and Mass Save paperwork. A 2025 Google reviewer praised the response time but described soot spewing from a brand-new boiler; that reviewer wrote that a fuel nozzle was replaced without correcting the problem, and that on a third visit the service manager said residual soot in the vent pipe was still clearing. A 2026 one-star reviewer called a technician a liar for saying the tank had a hole in the bottom, writing that there were no visible oil stains under the tank.
