"Our brand new system was not heating properly. Gary (FIVE STAR EMPLOYEE) came and fixed a problem. It was not straight forward and he had to do a bit of research, but he made it work better than it ever had!. He came back the next day and changed the filter and rec-hecked the system. We were warm and snug after his dedicated service! Thanks for the GREAT experience."

Boiler Repair questions, answered by experts

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

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

Yes, it is generally safe and effective to turn off radiators in unused rooms to save money on heating costs. This practice is especially beneficial with older heating systems. However, you should avoid cranking up the thermostats on the remaining radiators to compensate, as this can lead to higher heating bills and increased wear and tear on your system. While some HVAC specialists argue that modern, efficient boilers are designed to heat the entire home and work best when all radiators are on, turning off radiators in unused spaces still reduces the total amount of hot water your system needs to produce.
