"The ladies at the office were courteous and professional. Jennifer sent a picture of the person who would be coming to my home; Brad Johnson a Senior Service Technician! I only needed an inspection of my old furnace that was making a strange noise and taking a long time to kick on. He checked it thoroughly, reassured me that it was working, and vacuumed it out. He took the time to answer all my questions; he was friendly. The quirks of the furnace were just 'the nature of the beast,' (my add.). I found a company who's people that I can trust! It was worth every bit of money I paid. They all earned it! Thank you."

Install Boiler questions, answered by experts

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.
