Boiler Repair questions, answered by experts

It's possible that your oven's gas ignitor will wear out before the rest of the appliance. An ignitor may last about eight years before it needs replacing. In some cases, cleaning the ignitor to remove any built-up food and debris may help to prolong its life. Replacing the ignitor in a gas oven costs an average of $200.

Although baseboard heating is expensive to operate, hydronic style heaters usually aren’t as costly as other models because they maintain temperature longer than standard electric baseboard heaters. Since the liquid retains the heat longer, it prevents the thermostat from turning on and off as often, which makes it more energy efficient.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

Most repairs take 2-6 hours, but extensive repairs or part replacements may require a full day or more, depending on availability.
