Kermit B. Schulz & Sons, Inc. is a family-owned, third-generation HVAC company serving Millis, Medfield, and surrounding eastern Massachusetts areas. The company traces its service history to 1946 and provides heating and cooling installation, repair, maintenance, boilers, furnaces, central air, geothermal systems, mini-splits, ductwork, indoor-air-quality work, and emergency service.
The customer record is broad and mostly positive, with 39 reviews from 2018 through 2026. Recent reviews praise annual maintenance, furnace and AC installations, heat-pump work, clear explanations, fair or competitive pricing, and clean, professional crews. Several detailed accounts describe diagnosing difficult systems, responding quickly during winter failures, and completing custom ductwork or heat-pump installations.
There are exceptions to that pattern. A 2023 reviewer reported repeated unanswered calls about a delayed heat-pump project, and another 2023 review criticized incomplete tune-up work and inconsistent technician skill. A 2018 BuildZoom review also reports a very poor toilet-installation experience through Lowe’s, which is outside the company’s core HVAC work.
KBS is a strong fit for heating, cooling, heat-pump, boiler, furnace, and maintenance projects where detailed planning matters. Confirm the written scope, timing, warranty, and the exact service team before work begins, especially for projects involving multiple trades or equipment lead times.
