About W M Kramer & Son
W M Kramer & Son has kept Ohio families comfortable for more than a century, having operated continuously since the early 1900s. Based in Niles, this family-owned heating contractor serves Trumbull County and nearby communities including Warren, Girard, and Campbell. The company holds strong ratings with a 4.8 average across 37 client reviews, reflecting decades of consistent service to both homeowners and business owners. Their team handles traditional ducted systems, ductless split units, and commercial HVAC equipment, complemented by in-house sheet metal fabrication for custom ductwork needs.
What sets this contractor apart is their combination of old-school reliability and modern technical capability. They offer a 100% satisfaction guarantee, promising to make things right if a client is not totally satisfied with completed work. The company provides free estimates for new installations and repairs, allowing property owners to understand costs before committing. Their technicians maintain full certification and can service all major HVAC brands, though they emphasize recommending the right system for each customer's specific situation rather than pushing particular brands or upselling unnecessary equipment.
Customers describe specific technician experiences that illustrate their commitment. Amanda Biviano noted the team squeezed her in on a Saturday to install a new AC unit before summer arrived, and their attention to insulation work resulted in a cooler home with lower electric bills. Tim called regarding his son's failed central air on a Wednesday, and technician Joe arrived that afternoon to diagnose the problem, with a new system installed by Friday. Dan Miller praised their work on a 150-year-old house where they completed a same-day furnace and AC installation despite unique structural challenges. Several reviewers mention financing assistance, making major equipment purchases more accessible.
What Customers Say
32 of 37 reviews award 5 stars, with customers frequently naming technician Joe for same-day emergency response and careful explainers of repair options. Negative feedback centers on isolated scheduling delays rather than workmanship quality. Multiple clients note the company helped arrange financing for major equipment purchases.
