"Everything went great. The crew arrived right on time and was very polite and professional. Ali explained everything beforehand and the work was done exactly as described. After installation there were some minor adjustments to be made and Ali responded right away and took care of the problem. He was also able to get the ducting corrected to a part of the house that hasn't had ac for many years. I was very pleased with Ali and his crew."

"While out of town, got word basement might be flooded. Called Schede to check boiler and hot water heater.. They went out the same day. Discovered sump pump wasn't working so replaced it. Cost pump and labor $800. Over the years they have responded to many problems, leaking faucets and stuck drains. Biggest project replace boiler for steam heat. Took 5 guys to wrestle boiler down a narrow basement stairway. Patient with a few family disagreements. Nothing to do with them. Installation successful. They've always been prompt courteous and non judgemental when encountering crazy working conditions. Think they are great. Boiler and hot water heater were fine. They installed both."

"Furnace was not operating because the company's automatic delivery system ran me out of oil.
Technician showed up promptly and got the furnace operating but could not get heat into the house. Had to reschedule to have zone valves replaced. Technician show up late and didn't have the required parts. Had to reschedule again.
The third technician showed up on time with all the correct parts and worked most of the day to get the system operating properly.
He was completely knowledgeable and very conciencious that everything was working correctly.

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

Install Boiler FAQs, answered by experts

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.
