Boiler Repair questions, answered by experts

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

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.

Leaks, pressure loss, air in the system, burner failures, and thermostat malfunctions are common problems that require professional repair.

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.
