Boiler Repair FAQs

Do you service most boiler brands?

Yes—GEM services many common boiler systems and will recommend the best next step after diagnosis.

Do you work on radiators and baseboard heat?

Yes—boilers commonly heat radiators/baseboards, and we can diagnose circulation and comfort issues.

Why is my boiler losing pressure?

Common causes include leaks, expansion tank problems, relief valve issues, or air in the system. We’ll pinpoint the cause and recommend the right fix.

What do “kettling” or banging noises mean?

Often it’s related to water flow problems, scale buildup, or air in the system. We’ll inspect and confirm what’s happening.

When should I consider replacement instead of repair?

If repairs are frequent, parts are failing repeatedly, or the system is aging and inefficient, replacement may be the better long-term option.
