Why Hanover boilers need expert service

Many Hanover homes from the 1960s and 1970s have original hot-water boilers that were never replaced — now operating well past their design life on deferred maintenance.

Hanover's suburban growth in the late 1970s and 1980s added homes with early-generation high-efficiency boilers that are now developing heat exchanger and control board failures.

Boilers in Hanover often go unchecked between real estate transactions, with buyers inheriting systems in unknown condition.

Hanover's colder interior location compared to coastal towns means heating systems run harder and longer each winter.

How we handle Hanover boiler problems

Boiler diagnostic and repair

We identify the failing component — circulator, pressure relief, aquastat, expansion tank, gas valve — and repair it directly.

Pressure relief and safety check

PRVs and low-water cutoffs are safety-critical and fail silently. We test and replace these on every service visit.

Boiler replacement

When repair no longer makes economic sense, we replace with properly sized equipment, pull the MA permit, and commission correctly.

The $99 service fee sends a licensed technician out to diagnose the problem. Approve the repair on the spot and the fee is not charged at all; decline it and the $99 covers the visit.

How long do boilers last in Hanover homes?

Hot-water boilers in Hanover's 1960s and 1970s housing stock are often now 40 to 50 years old — well past typical service life. We assess condition and give you an honest repair-vs-replace recommendation.

My Hanover boiler keeps losing pressure. What's wrong?

Pressure loss usually means a leak somewhere in the system, a failing expansion tank, or a pressure relief valve that's stuck open. We diagnose the specific cause before recommending a fix.

Should I repair or replace my Hanover boiler?

If repair cost is under 40 percent of replacement and the unit is under 20 years old, repair usually makes sense. We give you both numbers honestly and let you decide.

Hanover runs entirely on its own groundwater. The town's water division operates nine wells across four separate well fields and three storage tanks, feeding a distribution network of about a hundred and ten miles of main, some fourteen hundred valves, twelve hundred hydrants, five thousand water services and roughly three hundred backflow prevention devices. What that arrangement means in a Hanover basement — water, sewer, and how the town was built — is on our Hanover plumbing page.
