Reliable Protection Against Winter Freezing, Sludge, and Contamination

When we receive service calls from grandparents desperately seeking to fix a broken heating system for their grandchildren, it breaks our hearts. We feel their love through the phone. We care about keeping your heating system healthy so no grandbaby ever endures a cold night.

We’re taking preventative measures to reduce burner breakdowns, sludge formation, and winter freezing. Hillside has begun treating our heating oil with a premium additive at no cost to our customers. The special heating oil treatment inhibits microbial growth, dissolves sludge, improves combustion, avoids breakdowns from clogged lines, strainers, and nozzles, disperses water accumulation, minimizes corrosion and prevents winter freeze-ups. This results in maximum energy output, fewer service calls, and increased savings.

We want to help prevent oil heating problems such as:
