Como Oil & Propane is a provider of residential, commercial, and Industrial heating fuels. We have nine offices throughout NE Minnesota and NW Wisconsin, and we dleiver heating oil and propane to over 22,000 customers. We also sell furnaces, water heaters, AC and grills. Cook & Douglas counties available.

"My 94 yo mother has been a customer of Como Oil for decades. She even pre pays for every home fuel oil fill. On 6-27-23 Como greatly overfilled the tank which is in a finished basement Where we live. Grade 2 Fuel oil spilled outside of the home and onto the foundation, and then it flooded the basement. The fumes were so intense we became very sick. I spoke with the Hibbing MN manager, who could have cared less what my elderly Mom was going through with the fuel oil spill inside her home!!! He told me it wasn’t his problem since it was inside the house. Don’t EVER do business with this company. We had a credit of over $3000 dollars at Como and they said it would take 6-8 weeks to CUT a refund check. Come on? What a pathetic response. They caused the toxic spill, my 94 yo mother did not cause it. They took advantage of her. We want everyone to know how little they care about their long term customers, and how they placed us at a high health and safety risk. The gas hot water tank pilot light was only 3 feet away from the liquid spilled fuel oil. I did not want to give Como even a 1 Star rating, they deserve a ZERO."

Heating Oil questions, answered by experts

Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.

Yes, including optimizing settings and suggesting upgrades if needed.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.
