The Hi-Ho Difference

Hi-Ho Energy Services is a trusted home heating oil and HVAC company, rich with history and longevity in the community. But we are much more than your oil company. We are your neighbors, too, and we treat our customers like members of our extended family.

For over 100 years, Hi-Ho Energy Services has been a fabric of the communities we serve. Keeping families warm, cozy, and safe in the winter and cool and  comfortable in the summer is what we do best. Unlike many of the other fuel providers who have diversified their product and service offerings, at Hi-Ho Energy Services, we have remained laser focused on providing best in class heating oil delivery and HVAC service to our customers. As a result, HiHo has earned the reputation of most trusted and reliable petroleum provider in Fairfield and lower New Haven Counties.

At Hi-Ho, we are large enough to meet the needs of all of our customers but small enough to know their names. Nurturing these relationships with customers, suppliers, employees, and neighbors has earned HiHo an A+ rating with the BBB time and time again. Any company can talk about best-in-class service, but insisting on it–and achieving it–day in, day out is what has anchored the Hi-Ho legacy for over a century.

A company committed to giving back to the communities it serves, HiHo Petroleum remains a bedrock of the community fostering relationships along the way.

From the friendly folks you chat with on the phones to the smiles our drivers and technicians wear almost as if they are part of their uniform, HiHo Petroleum has been your local, reliable heating oil and HVAC partner for generations–and you can rest assured we’ll be here for you, your family, your friends and neighbors for generations to come.
