Furnace & Boiler Service
What it covers
Our boiler service covers the water side, the pump, valves, pressure reading, expansion tank, and the controls that manage heat through the system. We also look for leaks around fittings, unusual sounds from the boiler cabinet, and radiators or baseboards that stay cold or heat unevenly. A property may need this work after long idle periods, after a reset, or when the system turns on but does not move heat through the building. One useful check is to note whether the pressure gauge changes when the heat starts.
What we check
What we check
Inside the furnace, we look at the switches, the air filter, and the condition of the cabinet. We check for loose wires, worn wiring, and rust at the seams because those details can point to wear or leaks in the unit. The blower wheel and motor get checked for dirt buildup, noise, and drag since air movement affects how the system starts and runs. We also test the thermostat signal and the control board connections, and we note any tripped safeties before we move on.
For boiler service, we check the pressure gauge, relief valve, circulator pump, and the water level where the system uses it. We look at valves, piping joints, and the expansion tank for signs of seepage or strain because water loss or pressure changes can affect operation. Controls and wiring get tested for a clean signal from the thermostat to the boiler. On units with a blower, we check the fan motor, belts if present, and the relay so the airflow matches the call for heat. We also ask you to keep the area around the equipment clear for easy access.

Choices to make
Choosing between repair and replacement starts with the furnace or boiler cabinet, the blower and pump area, and the parts that move air and water. We look at the control board, blower motor, pump, switches, and wiring for wear, loose connections, or repeated faults. A repair can make sense when the problem stays in one part and the rest of the unit is steady. Replacement can come up when the cabinet is rusted, a pump is leaking, or several parts are failing together. A record of past repairs helps us compare the options.
The decision also depends on how the system fits the building. We check the ductwork or piping, the thermostat wiring, and the space around the unit before suggesting a path. For a boiler, we look at water leaks, pump noise, and pressure changes. For a furnace, we look at airflow, filter condition, and how the blower starts and stops. If the control board has repeated lockouts, we test the sensors and the relay points before treating it as a simple part change. Loose thermostat wires can mimic a bad board.

After the work
After the visit, you have a clear picture of what we found in the furnace or boiler and what we checked in the air mover, controls, and safety parts. We note loose wiring, worn belts, dust buildup, blocked return grilles, leaks at fittings, and any parts that show wear. If we cleaned or adjusted anything, we explain what was done and what still needs attention. Keep the area around the unit clear, and check that access panels stay closed after routine use.
For upkeep, watch for short cycling, uneven heat, rattling, repeated shutoffs, or water around the boiler base. Those signs can point to a control issue, an airflow problem, or a part that needs a closer look. We also check the blower wheel, relay, and control board for dust, corrosion, and loose connections, because those parts affect how the system starts and runs. Replace filters on the schedule for your system, and make sure return grilles stay open and clear of dust.

Questions
Furnace & Boiler Service: common questions
My furnace runs, but the house stays cool. What could be wrong with the blower or control board?
We would look at the blower motor, fan speed settings, wiring, and control board signals. A furnace can run without moving enough air if the blower has a weak motor, a dirty wheel, a loose connection, or a board that is not sending the right command. We also check the filter, because restricted airflow can change what the system does.
I hear my boiler clicking on and off, but the radiators never warm up. What are you checking?
That kind of cycling can point to a control issue, a circulation problem, or a sensor that is not reading correctly. We examine the thermostat call, pump operation, water level, pressure, and the control board if the unit uses one. Small changes in those parts can affect whether the boiler starts, keeps running, or shuts down early.
My furnace filter gets dirty fast. What maintenance does the furnace need besides changing the filter?
Regular furnace maintenance includes more than the filter. We look at the blower compartment, belts if your unit has one, electrical connections, drain parts where present, and the condition of the switches and controls. Dust buildup inside the cabinet can affect airflow and operation. A maintenance visit also helps us spot worn parts before they stop working.
The boiler makes a lot of noise when it starts. Is that the pump or something else?
Noise at startup can come from air in the lines, a pump issue, a loose mounting point, or a part that is shifting when the system powers up. We listen to the sequence, check the pump, inspect the piping around the boiler, and look at controls that tell the unit when to run. The sound often gives clues about where to begin.
My furnace stopped responding after I changed the thermostat batteries. Could the control board be the problem?
It could be, but we would not assume that first. We check the thermostat wiring, power to the furnace, transformer output, fuse condition, and the control board for visible damage or an error pattern. A simple power interruption can leave the system waiting for a signal that never arrives. We also verify whether the blower and safety switches are closing properly.
