Boiler Repair, Installation & Maintenance Warwick RI

Oil, gas, condensing — we service all three. Most Warwick no-heat calls are wrapped same-day. Pre-winter tune-ups September through November.

Annual maintenance

What we check on a Warwick boiler tune-up

The 8 items below are the ones that prevent the most mid-winter no-heat calls. Full service covers 17 points; the rest are inspect-and-document.

1

Combustion analysis (CO, O₂, stack temp)

Verifies the burner is running clean — the #1 cause of mid-winter shutdowns is incomplete combustion fouling the heat exchanger.

2

Expansion tank pressure & charge

Waterlogged expansion tank = high-pressure shutdowns on cold mornings. Cheap to recharge, expensive to ignore.

3

Circulator pump operation

20-year-old Taco 007s seize on the first hard cycle of the season. We test under load, not at rest.

4

Relief valve test (T&P safety)

If the relief valve is corroded shut and pressure rises, the boiler shell can rupture. Annual test is code.

5

Flame sensor & ignition cleaning

Soot buildup on the flame sensor = intermittent no-heat lockouts. Five-minute cleaning prevents a January service call.

6

Zone valve / thermostat verification

Zone valves stick partially closed silently — one zone runs cold, you blame the thermostat. We test each zone.

7

Hydronic loop air purge

Trapped air kills heat transfer in baseboards. Quick purge restores upstairs zones that 'never quite warm up.'

8

Chimney draft check (oil-fired)

Older Warwick clay-tile chimneys lose efficiency. Critical safety check on oil units that vent through them.

Oil-to-gas conversion

ROI math for a typical Warwick conversion

Below is the framework we walk Warwick homeowners through when we quote an oil-to-gas conversion. Specific numbers depend on your home's annual oil consumption and the gas service drop required — quoted on-site.

Annual fuel cost
Substantial savings vs oil at current RI gas/oil pricing
Project scope
New gas-fired condensing boiler, gas service drop, chimney liner — quoted per home
Payback period
Typically 6–9 winters at current RI gas/oil pricing
Basement footprint
Wall-hung condensing unit, no tank
Maintenance frequency
Annual combustion test, condensate trap
Efficiency at install
95%+ AFUE on condensing units

Repair or replace

Decision by boiler age

We'll always quote the repair. We'll also tell you straight when the math no longer works.

Age

0-7 years old

Action

Repair

Component swap. Heat exchanger is healthy, full life ahead. Repair always wins economically.

Age

8-14 years old

Action

Repair, but plan

Repair the immediate failure but start budgeting. Get a quote on replacement so you're not deciding under crisis.

Age

15-20 years old

Action

Decide on the math

If the repair is significant and the unit is 78% AFUE, replacement payback is usually under 6 winters. We'll quote both paths and let you choose.

Age

20+ years old

Action

Replace

Heat exchanger fatigue is hard to predict. Major repair on a 22-year-old boiler typically only defers replacement by 12-18 months. Bad bet.

Boiler service FAQ — Warwick

Is converting from oil to gas worth it on an older Warwick boiler?+

On most older Warwick homes — particularly mid-century ranches and split-levels through Greenwood, Hoxsie and Norwood — the oil-to-gas conversion typically pays back in 6-9 winters. The 275-gallon basement oil tank goes away too, freeing real square footage. We handle gas line, boiler swap, and chimney liner as one project.

When should I book a boiler tune-up for my Warwick home?+

September through November. Humidity off Greenwich Bay drives heat-loss harder than the thermometer suggests, so Warwick boilers run more cycles than comparable inland homes — a fall combustion test, expansion tank check and circulator pump run is what keeps a January no-heat call from happening.

Do you install high-efficiency condensing boilers in Warwick?+

Yes. Modern modulating-condensing boilers (95%+ AFUE) typically cut a Warwick home's heating bill 25–35% versus an old 78% atmospheric unit. We size based on a Manual J load calc — not the BTU rating that was on the old unit, which is almost always oversized for an updated home.
