Heating and cooling in Northern Ohio houses

This climate is hard on equipment. A furnace here runs from October into April, then the same blower turns around and moves cooled air through July and August. That's a long duty cycle on one machine, and it's why the failures we see cluster in predictable places: ignition components, inducer and blower motors, control boards cooked by years of heat, and coils that never got cleaned.

On the heating side, most homes around Brunswick, Strongsville and North Royalton run a forced-air gas furnace. The older eighty-percent units vent up a masonry chimney and are simple, sturdy things — but if the house has been through a water heater swap or a furnace upgrade, the chimney is often oversized for what's left venting into it, and that causes condensation and corrosion problems that nobody notices until a flue pipe rusts through. Newer ninety-plus condensing furnaces vent out the sidewall through PVC, which brings its own list: blocked intakes, condensate traps clogged with slime, and drain lines frozen where they exit into an unheated space.

When a furnace won't run at all, the diagnosis follows the sequence of operations. Is there a call for heat, does the inducer start, does the pressure switch close, does it spark, does the gas valve open, does the flame sensor prove the flame, does the blower come on. Any experienced tech can walk that in ten minutes with a meter. What separates a real diagnosis from a parts swap is checking the things that caused the part to fail — a filter someone hasn't changed since spring, closed registers in half the bedrooms, or an undersized return that's been starving the unit since the house was built.

Replacement is the other half of the job. When a furnace is 20 years old and the heat exchanger has cracked, we're not going to try to repair it. What we will do is size the replacement to the house rather than to the label on the old one. Furnaces got oversized for decades, and an oversized unit blasts, satisfies the thermostat in six minutes, and shuts off, leaving the far bedrooms cold and the equipment cycling itself to an early grave. We look at square footage, insulation, windows and duct capacity and put in what the house actually calls for.

Air conditioning gets less attention here because the season is short, which is exactly why so many systems limp. Central air fails in one of a handful of ways: a capacitor that no longer has the punch to start the compressor, a contactor pitted from years of arcing, a condenser coil packed with cottonwood and grass clippings, a refrigerant leak, or an indoor coil frozen solid from restricted airflow. Same approach as heating — find the cause, tell you what it costs, then fix it. On replacement, the condenser and the indoor coil have to be matched, and if the furnace is old enough that it's coming out soon anyway, we'll say so instead of installing half a system.

Ductwork rarely gets mentioned in a sales pitch, but it decides whether any of this works. A perfectly good furnace connected to a single undersized return will never heat evenly. Where it matters we'll tell you what a return addition or a duct repair would do, and what it costs, so you can weigh it against the equipment.
