"Recently, during the cold spell, our boiler began acting up, turning on intermittently with just a little nudge each day. After reaching out to several companies for estimates, we chose M&R to replace our 50-year-old boiler. Tom was the first to arrive to assess the situation and provide an estimate. Once we decided to move forward, M&R was responsive and punctual with their appointments. The team handling the installation consisted of Dex, Jake, Josh, and Tony. They were professional, respectful of our property, and made sure to clean up the area around the boiler. The installation was completed in one day. Tony also stopped by twice to check on the progress and made adjustments to sync up our zones. We are very happy with the work and professionalism of the entire team and are glad to recommend M&R to anyone in need of heating repair or replacement. "

Boiler Repair questions, answered by experts

You save money on heating oil in a few ways:

  • Make sure your home is well insulated and sealed against drafts and heat leakage.

  • Use a thermostat that’s working properly and calibrated accurately.

  • Increase energy efficiency by insulating your basement and attic.

  • Turn down your thermostat a few degrees.

  • Program your thermostat to lower the heat when you’re not home.

  • Order heating oil during the off-season when prices are likely to be lower.

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.

It can be difficult to determine the cause of a coolant leak unless you have the unit inspected by a certified professional. Most coolant leaks are caused by wear and tear on seals and joints. This typically happens five years after a unit is installed. Additionally, faulty or worn compressors, evaporator coils, and condenser coils can also cause leaks.

Regular maintenance includes annual inspections, filter changes, and checking for leaks or pressure inconsistencies to improve efficiency and longevity.

Addressing gaps and cracks reduces heat loss and improves energy use.
