Frequently Asked Questions — Boiler & Oil Heating
Why is my boiler not producing heat?
Common causes include a pressure problem, a failed ignition or pilot, a circulator-pump issue, or a safety lockout. We diagnose the exact cause and explain your options before any work begins.
Do you service oil boilers and oil heating systems?
Yes — oil heating is one of our specialties. We repair, tune, and replace oil boilers, oil furnaces, and oil burners across the Merrimack Valley.
How fast can you get my heat back on?
We offer same-day boiler service whenever our schedule allows. Call (978) 452-2766 or text 978-216-0555 early in the day for the best chance at a same-day visit.
Why is my boiler making banging noises?
Banging or “kettling” is often caused by trapped air, low water pressure, or mineral buildup. It’s usually fixable — we’ll find the cause and check the rest of the system while we’re there.
Should I repair or replace my boiler?
If your boiler is over 15–20 years old and needs a major repair, a high-efficiency replacement is often the smarter investment. We’ll assess it honestly and show you the numbers.
