Gas Furnace Repair in Parma, Ohio

Gas heats about 87 percent of Parma homes (gas furnaces in Parma homes), and most of that gas burns in a forced-air furnace in the basement. When one of those furnaces stops heating, the cause is usually one part in the ignition and safety chain, not the whole furnace. We repair gas furnaces of every age, from standing pilot units still running in 1950s basements to two-stage and modulating 90 percent furnaces vented with PVC pipe.

Furnace repair covers the parts that light the burners and prove the flame, the parts that move air, and the controls that tie them together:

  • Hot surface igniters and spark igniters that crack or wear out
  • Flame sensors coated with residue, so the burners light and then shut off after a few seconds
  • Inducer (draft) motors that hum, rattle or fail to start
  • Pressure switches and the small hoses and ports that feed them
  • Gas valves, thermocouples and pilot assemblies on older furnaces
  • Blower motors, run capacitors and blower wheels packed with dust
  • High limit switches and rollout switches that trip and lock the furnace out
  • Control boards, transformers, door switches and loose wiring

Why Furnaces Work So Hard Around Cleveland

NOAA's 1991 to 2020 normals for Cleveland Hopkins Airport count about 5,500 heating degree days a year against about 950 cooling degree days (Cleveland Hopkins heating degree days). The heating load here is roughly six times the cooling load. January alone averages a low of 22 degrees, and about 111 nights a year drop to freezing or below.

That many hours of run time is what wears furnace parts out. Igniters crack after thousands of heat cycles. Inducer and blower motor bearings dry out. Filters load up faster through a long winter, which cuts airflow, heats the heat exchanger past its limit and trips the high limit switch. In December, January and February those wear parts are the usual cause of a furnace that stops heating.

Furnace Repair in Parma's 1950s and 1960s Houses

Parma grew from about 29,000 people in 1950 to almost 83,000 in 1960 (1950s houses across Parma), and the median Parma home was built in 1958. Many of those houses are on their third or fourth furnace, but the ducts, the return grilles and the chimney are often the originals. A modern furnace on 1950s ductwork can run hot and shut off on its limit switch. An 80 percent furnace on an old, oversized masonry chimney can have draft problems that show up as a pressure switch fault.

South of Pleasant Valley Road and in towns like Seven Hills and Middleburg Heights, more houses date from the 1960s and 1970s. In North Royalton the 1990s were the biggest building decade, so 90 percent furnaces with condensate traps, drains and pumps are a bigger share of the work there.

Snow-Blocked Furnace Vents and Frozen Drains

Cleveland Hopkins averages about 64 inches of snow a year, and lake-effect snow off Lake Erie can pile it up fast. A 90 percent furnace pulls combustion air in and pushes exhaust out through two white PVC pipes, often low on a side wall. When drifting snow or frost closes one of those pipes, the pressure switch opens and the furnace locks out. The same furnace drains water from its condensate trap, and a drain line run outside can freeze shut on a single-digit night. Both problems look like a dead furnace and both are repairable.

Furnace Repair Questions

How many times will a furnace try to start?

Most modern furnace control boards try to light the burners a few times, then lock out and flash a fault code on the board's light. The usual causes are a dirty flame sensor, a weak hot surface igniter, a pressure switch that will not close, or a gas valve that does not open.

Will a furnace still run if the pilot light is out?

On an older standing pilot furnace, no. The thermocouple keeps the gas valve closed when the pilot is out, so the burners never light, though the blower may still push cold air. The repair is usually the thermocouple or the pilot assembly.

What are the signs that my furnace blower motor is going bad?

Weak airflow from the registers, a hum with no air moving, squealing or grinding, a motor that runs hot and shuts off, or a blower that starts late or not at all. On many motors the run capacitor fails first, and replacing it brings the motor back.

Can you just replace a blower motor on a furnace?

Yes. The motor can be replaced by itself as long as the horsepower, rotation and speeds match, along with its capacitor on a standard motor. Variable-speed motors sometimes need only their control module. The blower wheel gets cleaned while the motor is out, since a caked wheel strains the new motor.

Why does my furnace sound like an airplane taking off?

Usually the blower on high is fighting a clogged filter or return ducts that are too small, or the inducer motor bearing is wearing out. Air rushing through closed registers or a loose duct joint makes the same roar. A sudden change in the sound points to the inducer or blower motor.

Why is furnace making humming noise?

A failing run capacitor, a blower motor trying to start, a transformer hum, or an inducer motor with worn bearings. A hum with no air coming out of the registers usually means the blower motor is stuck or its capacitor is dead.

What does furnace short cycling sound like?

The burners light, run for a short time and shut off while the blower keeps going, then the furnace starts again a few minutes later. Common causes are a high limit switch tripping on poor airflow, a dirty flame sensor, or a furnace too big for the house.

How long can a furnace run without shutting off?

On the coldest nights a furnace sized right for the house can run long cycles or close to nonstop, which is normal. Running nonstop on a mild day is not: it points to a clogged filter, leaky ducts, a weak burner or a furnace too small for the house.

Why won't my electric furnace turn on?

Check for a tripped breaker first. Beyond that, the usual parts are the door safety switch, the transformer, the sequencers or relays, the heating elements and the limit switches. Electric furnaces are more common in North Royalton and in apartments and condos around Parma Heights.
