When the heat goes out in Somerville, MA, the clock starts running, and the diagnosis depends entirely on what kind of system is doing the failing. On a gas furnace, the single most frequent culprit is a flame sensor coated in oxide: the burners light, the sensor cannot prove the flame, and the board shuts the gas down after the third attempt and locks out. Close behind come cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors that have quietly worn out. Heat pumps fail differently: a weak defrost cycle leaves the outdoor coil buried under frost, a failed reversing valve strands the system in cooling, and a dead outdoor unit leaves the electric backup strips carrying the whole house at several times the operating cost.

Signs You Need Heating Repair in Somerville

Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:

  • Cold rooms in one part of the house while others are comfortable
  • Heating bills spiking while comfort keeps falling
  • Banging at startup caused by burners lighting late
  • An outdoor heat pump coil that stays iced over
  • No warm air at the registers even with the heat turned up
  • Strange smells from the vents, especially rotten egg or burning
  • A furnace that tries to light, clicks, and then quits
  • Short cycling every few minutes while the house stays cold

Early Action Saves Money

Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. Call (857) 767-3378 at the first sign of trouble.

How We Handle Heating Repair

Fault codes are where our diagnosis starts, not where it ends. On every no-heat call, Somerville HVAC confirms the board's story with measurements: flame signal read in microamps, igniter resistance checked, the pressure switch tested against real inducer draft, capacitors and motors metered, and, on heat pumps, refrigerant charge and defrost operation verified. Any visit that touches the gas side also covers the safety basics. We leak-test the connections, look over the heat exchanger, and confirm the flue is drafting, since no heating repair is finished until it has been proven safe.

Furnace, heat pump, air handler, boiler, or ductless unit, from any major brand, we service it. Stocking igniters, flame sensors, capacitors, inducer motors, and blower motors on every truck means heat usually comes back on the first trip. And if a repair no longer makes sense for aging equipment, we will be honest about that and lay out the options with real numbers. Call (857) 767-3378 for heating repair anywhere in Somerville, and we will get the warm air moving today.

What to Expect From Our Heating Repair

Our systematic workflow delivers thorough, lasting results on every job.

1

Diagnosis & Safety Inspection

Each call begins with measurements, not guesses: flame signal, igniter resistance, pressure switch response, and motor and capacitor health, plus refrigerant charge and defrost on heat pumps. Gas connections are leak-tested as a matter of course.

2

Straight Answers & a Firm Price

We show you what failed and why, and give a firm price before work begins. If a cracked heat exchanger or dead compressor changes the math toward replacement, we say so plainly.

3

Same-Visit Repair

Igniters, flame sensors, pressure switches, capacitors, and motors ride on our trucks, so most heating repairs are completed the same visit and the house starts warming before we leave.

4

Complete System Check

A repair is not done until the system proves itself. That means full cycles, temperature rise checked against the data plate, combustion and draft confirmed on gas equipment, and every safety control verified.

Heating Repair FAQ

Don't see your question? Call and ask a technician.

Call (857) 767-3378
On heat pump systems, a spike often means the electric backup strips have taken over because the heat pump itself has a problem. On furnaces, short cycling, a failing blower, or duct leakage makes the system work harder for less heat. Either way the meter is telling you something broke. Call (857) 767-3378 and we will find it in Somerville.
A thin layer of frost is expected in cold weather, and the defrost cycle should melt it off regularly. Heavy ice that stays put is a different story. The usual causes are a failed defrost board or sensor, a low refrigerant charge, or restricted airflow across the outdoor coil, and running the unit that way puts real strain on the compressor. Call (857) 767-3378 and we will diagnose the defrost system properly.
Igniters, sensors, switches, and motors are worth repairing at almost any age. A cracked heat exchanger or a failed compressor on equipment past the fifteen-year mark usually tips the math toward replacement, especially with the efficiency gains of modern systems. We give you honest numbers either way. Call (857) 767-3378 for straight answers.
In most cases, the flame sensor is to blame. When it is coated or worn, it cannot confirm that the burners are lit, so the board shuts off the gas to be safe. That said, a weak igniter, a sticking pressure switch, or a plugged condensate trap can look very similar, so we test all of them before replacing anything. Call (857) 767-3378 and we will end the lockouts in Somerville.

The Benefits of Professional Heating Repair

Heating repair carries the highest stakes in home comfort work because combustion is involved. A furnace that lights late booms gas vapor inside the heat exchanger and stresses the metal; a heat exchanger that cracks can pass combustion gases into the supply air; a flue that has stopped drafting sends carbon monoxide into the house instead of out of it, and none of these announce themselves in ways an untrained eye can catch. The diagnostic terrain is genuinely tricky too: a furnace that short-cycles might have a failing limit switch, or it might be protecting itself from a clogged filter, and cleaning a flame sensor without asking why it fouled leaves the next lockout already scheduled.

That is why Somerville HVAC does not guess. Our technicians read flame signal on a meter, look at the heat exchanger directly, confirm the flue is drafting, and compare temperature rise to the data plate to make sure the blower speed fits the burner. On heat pumps we check defrost controls, sensors, and the reversing valve before blaming the compressor, and we find out whether the electric backup heat has been running in the background and driving up your costs. Nothing is called fixed until it has run a full cycle and proven itself safe and correct, because your family's warmth and safety depend on it.

Maintenance Tips for Heating Repair

A few simple habits now, like regular filter changes and seasonal tune-ups, can add years to your system's life. Here are our expert recommendations:

  • Give the outdoor heat pump unit open space, free of snow drifts and plantings, so it can defrost
  • Have the system serviced each autumn, before the weather tests every weak component
  • Test carbon monoxide detectors monthly and put one on every level of the home
  • Move solvents, paints, and pool or laundry chemicals away from the furnace to protect the burners from corrosive vapor
  • Change the filter monthly in heating season; starved airflow trips limit switches and cracks exchangers early
  • Call about booming at startup or new rattles right away, while the fix is still inexpensive
  • Keep the area around the furnace clear so the burner gets adequate combustion air
