Claim This BusinessJennings Oil and Propane has been family owned and operated for over four decades, delivering heating oil and propane to homeowners across Danbury, New Milford, and the surrounding communities in Fairfield, Litchfield, and New Haven counties. The company maintains an exceptional 4.8-star rating drawn from 182 customer reviews, reflecting a track record of reliable delivery and responsive service. In addition to fuel delivery, Jennings offers equipment sales and installation for boilers, furnaces, air conditioning units, and both oil and propane tank systems. The business operates Monday through Friday from 7 AM to 4 PM, with emergency service available for existing customers who need urgent heating assistance.
What distinguishes Jennings from other fuel companies in western Connecticut is their commitment to proactive customer care rather than reactive problem-solving. They offer annual preventive maintenance plans designed to catch potential equipment failures before they become middle-of-the-night emergencies. Their service contracts provide budget-friendly payment options, including email invoicing and ACH electronic payments for customer convenience. The company holds partnerships with industry organizations including the National Energy Fuels Institute and participates in Connecticut energy programs through EnergizeCT, connecting customers with available rebates on high-efficiency heating equipment upgrades.
The recent reviews reveal specific scenarios that illustrate their service approach. One customer needed a boiler repair just before Christmas 2025 when the heating system failed on a freezing morning; Jennings had a technician arrive before noon, diagnosed the faulty component, and completed the repair so the family could enjoy a warm holiday. Another reviewer described how Jenningsdelivered heating oil on a Saturday specifically to ensure the household had sufficient fuel before an incoming snowstorm, navigating a challenging steep driveway to prevent the customer from being left without heat in hazardous conditions.
All five detailed reviews award five stars, with customers consistently praising prompt response times, professional technicians, and the company's willingness to go beyond standard delivery schedules during weather emergencies. The reviews mention same-day Saturday delivery before storms, pre-delivery tank inspections, and repairs completed within hours of the service call.
