Boiler FAQs
How often should a boiler be serviced?
Most residential boilers should be professionally serviced once per year, ideally before the heating season begins. Annual maintenance helps ensure safe operation and reliable performance during winter.
How long does a boiler typically last?
With proper maintenance, many residential boilers can last 15–25 years. Lifespan depends on usage, water quality, and how consistently the system is serviced.
What are common signs of boiler problems?
Uneven heating, unusual noises (banging or gurgling), water leaks, rising energy bills, or frequent pressure loss may indicate your boiler needs professional attention.
Is a boiler more efficient than a furnace?
Boilers provide radiant heat through water rather than forced air. Many homeowners find radiant systems deliver more even, comfortable heat, and high-efficiency models can reduce energy costs.
