Chalker Heating & Fuel, LLC

Chalker Heating & Fuel is a family-run Cataumet outfit that Mark and Terry Chalker say they've operated since 2009, building on the couple's Cape Cod heating and fuel experience going back to 1986. The company delivers home heating oil, diesel and biofuel and installs and services heating, air conditioning and plumbing systems across Cataumet, Wareham, Falmouth, Plymouth and Yarmouth. Its website describes the business as woman-owned, veteran-owned and family-owned. Chalker's BBB record backs up the longevity: an A+ rating with accreditation dating to 2010. Its Google reviews, from 2021 through this spring, mostly describe routine oil-service and delivery calls going smoothly — reviewers in March and April 2026 praised fair pricing and a thorough, knowledgeable technician named Rich, and a 2022 review called the delivery drivers fast, efficient and friendly. The one sour note in the record is a 2021 review about an air conditioning installation: the customer said Chalker took nearly 12 weeks to come back with a quote, then told them their engineers had gotten the quote wrong and the company was too busy to take the job — after five unreturned follow-up calls. That's an isolated, older account, but it points to a real risk on bigger installation jobs specifically, distinct from the routine oil-delivery and service work the rest of the record covers well. For heating oil delivery and routine burner service on the upper Cape, Chalker's record holds up; for a larger AC or heating installation, it's worth pinning down a firm quote timeline up front.
