KELLER ENTERPRISES

KELLER ENTERPRISES has kept Northampton-area homes warm since the 1930s, making it one of the Lehigh Valley's longest-operating heating fuel and equipment providers. The family-owned business holds a 4.4-star rating across 28 reviews and operates Monday through Friday from 8 AM to 4 PM. Beyond Northampton itself, the company delivers heating oil and kerosene to dozens of surrounding communities including Allentown, Bethlehem, Emmaus, and Nazareth, providing both fuel delivery and HVAC installation services to a geographically broad customer base.

What distinguishes KELLER ENTERPRISES is its dual focus on traditional hearth heating and modern HVAC systems. The company installs and services coal stoves, oil stoves, boilers, and central heating systems, while also handling contemporary cooling equipment. Their website explicitly promotes pre-buy and budget programs for the 2025-2026 heating oil season, offering customers financial planning options for winter fuel costs. The hearth and home division covers fireplace inserts, gas log sets, and fireplace accessories, giving the business a broader product scope than typical heating oil suppliers.

Reviewers highlight specific technicians who delivered exceptional service. Vincent Genovese described how Jason and Zach worked through a brutal heat wave to diagnose a fried circuit board in his split AC system, calling out Jason for going above and beyond. A first-time coal furnace owner praised Steve for arriving on time, thoroughly cleaning the furnace, oiling motors, and providing hands-on instruction on operating the system. Another reviewer noted a same-day gas stove repair where the technician identified and fixed a persistent pilot light issue within hours of the morning call.
