Boiler Repair questions, answered by experts

Over time, a radiator can leak if turned off due to the built-up air pressure, which can cause water or coolant to leak. If your radiator leaks when it’s off, turn your whole system off and bleed the radiator, then turn it back on. If it’s still leaking, you might want to have an HVAC professional look at the issue.

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.

It is usually worth it to repair your HVAC system instead of replacing it. However, one exception is if your system is reaching the end of its life—usually 15 to 25 years. Otherwise, repairs will cost an average of $350, and a full HVAC replacement would total $7,500 in most cases, or between $5,000 and $22,000, depending on the type of system. A reputable HVAC repair company can inspect your system and let you know if replacing it would be more cost-effective.

In general, it’s a good idea to bleed air from your heaters at the start of every cold season, before you move your boiler system back into active mode. Early fall is a common time for this task. However, some heating systems don’t need much manual bleeding because of automatic bleed vents and other components.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.
