Franklin Boiler Installation FAQs

How long does a boiler typically last?

Most residential boilers deliver 15–20+ years of service when properly sized, installed, and maintained. Factors like water quality, venting, and annual tune-ups influence lifespan. If your unit is near the end of its expected life and needs frequent or costly repairs, upgrading can improve comfort and reliability while reducing operating costs.

Should I repair my boiler or replace it?

We look at age, safety, efficiency, frequency of breakdowns, and the cost of the repair relative to replacement. If a single component has failed on an otherwise sound, younger system, repair often makes sense. If the boiler is older, inefficient, or has multiple issues (heat exchanger corrosion, repeated ignition faults), replacement usually provides better ROI, especially with today’s high-efficiency models.

How long does a boiler install take?

A straightforward replacement is commonly completed in one day; more complex projects with new venting, piping reconfiguration, or multiple zones may require two. Our team coordinates permits, inspections, and cleanup so your heat is restored as quickly and safely as possible.

Will a high-efficiency boiler lower my energy bills?

Upgrading to a properly sized, high-efficiency boiler can significantly reduce fuel use compared to older equipment, especially if your current unit is oversized or poorly tuned. Many homeowners also notice quieter operation and more even heat. Ask us about current rebates and incentives that may further improve your payback.

What size boiler do I need for my home?

Proper sizing is critical for comfort and efficiency. Your contractor should perform a heat-load calculation (not just replace “like-for-like”) that considers square footage, insulation, windows, and distribution (baseboard, radiators). An accurately sized boiler will cycle correctly, reduce fuel use, and extend equipment life while keeping every room comfortable.
