Boiler Repair questions, answered by experts

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.

Both hydronic and electric hydronic heaters usually come with a higher price tag up front, but you can save more on energy costs over time compared to standard heaters. They also provide heat for a short time after the heater is actually turned off, making them more efficient. Additionally, standard convection heaters use electric coils to heat up the air, whereas hydronic heaters warm up water or oil which then heats the air.

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.

A poorly maintained boiler can lead to serious issues like deadly carbon monoxide poisoning, so schedule regular maintenance services. Of course, it’s also a good idea to check your carbon monoxide detectors in your home to make sure they’re working properly. Moreover, when you forget to maintain your boiler, small problems can lead to something much more serious, which will cost you more money in the long run. Repairs average around $400, while a full replacement can total over $6,000.

If your radiator turns on every time you turn on your hot water, your problem is likely your motorized three-port valve that’s attached to your boiler. When it malfunctions, the valve isn’t closing properly, so the water begins to flow to your radiator, thus kicking off the heat. To fix this, hire a boiler repair tech near you to replace your valve.
