- 1If you smell gas, leave the house and call your gas utility or 911 from outside. Do not touch switches.
- 2Check the thermostat: set to Heat, a few degrees above room temperature, with fresh batteries.
- 3Check the boiler's service switch (often a red plate at the top of the basement stairs) and the breaker.
- 4Look at the pressure gauge on a hot-water boiler. Note the reading and any blinking error code for the technician.
If the boiler still will not fire, do not keep pressing the reset button. Repeated resets on an oil or gas boiler can flood the chamber or mask a safety problem.

Steam or hot water? It changes the repair
Many Medford homes heat with boilers, and older houses often still run steam. The two systems fail differently.
| Steam boiler | Hot-water (hydronic) boiler | |
|---|---|---|
| How it heats | Boils water; steam rises to radiators and condenses back | Pumps hot water through radiators or baseboard |
| What you see | Sight glass with a water line, pressure in ounces or a few psi | Pressure gauge, typically around 12 to 20 psi when running |
| Common complaints | Banging pipes, cold radiators, low water cutoff lockouts | Cold zones, air in lines, leaking relief valve, failed circulator |
| Typical fixes | Main and radiator vents, skimming, pitch of pipes, low-water cutoff | Bleeding air, circulator or zone valve replacement, expansion tank |
| Homeowner check | Water level in the sight glass | Pressure gauge reading |
If you are not sure which you have, a photo of the boiler and its gauges helps the technician.

Why boilers matter here
Medford's housing stock is old by national standards. Many homes and two-families were built before the Second World War, and triple-deckers and Victorians across the city were designed around steam or hot-water boilers with cast-iron radiators.
A lot of those systems have been converted or replaced over the years: oil to gas, steam to hot water, old cast iron to compact high-efficiency condensing boilers. That mix means the right technician needs to understand both old piping and new controls.
Winters bring long cold stretches, and a boiler that fails overnight in January can leave pipes at risk of freezing in exterior walls and unheated basements. That is why no-heat calls are treated as urgent.
Renters and landlords
Heat rules in Massachusetts rental housing
The state sanitary code sets minimum heat for rental housing during the heating season. Know the basics.
- From September 16 through June 15, landlords generally must keep habitable rooms at least 68°F between 7 a.m. and 11 p.m. and at least 64°F overnight, unless the tenant controls and pays for the heat.
- Tenants should report no-heat problems to the landlord or property manager in writing, as soon as they happen.
- If heat is not restored, the local board of health can inspect.
- In multi-family buildings, one boiler may serve several units. The owner arranges repair.
- Keep space heaters away from curtains and bedding, and never use an oven or grill for heat.
This is a summary, not legal advice. See the Massachusetts State Sanitary Code (105 CMR 410) or ask your local board of health.

Boiler questions from Medford homeowners
Why does my boiler keep shutting off?
Common causes are a dirty flame sensor or ignition problem, low water triggering the low-water cutoff, a blocked vent or a faulty pressure or temperature control. Repeated lockouts need diagnosis, not repeated resets.
What pressure should my hot-water boiler be at?
Many residential hot-water boilers run roughly 12 to 20 psi, depending on the building height. A gauge at or near 30 psi, or water from the relief valve, means something is wrong. Steam boilers run at much lower pressure.
Who can work on a gas or oil boiler in Massachusetts?
Gas work requires a licensed gas fitter or plumber; oil burner work requires a certified oil burner technician. Ask the technician which license they hold.
Should I repair or replace an old boiler?
Cast-iron boilers can last a long time. Replacement is usually considered when the heat exchanger or section is cracked, repairs are frequent, or efficiency is very poor. Mass Save offers incentives for some high-efficiency heating equipment, which can change the numbers.
Is banging in steam pipes dangerous?
Usually it is water hammer from trapped condensate, not a safety issue, but it stresses the piping and can be fixed.
Is the call free?
Yes. You only pay the technician for work you approve.
