Older homes in Union heat differently than newer ones. Some rely on boilers that push steam through radiators; others have furnaces that force hot air through ducts. Both systems break, and both need quick diagnosis and repair from someone who's worked on Union heating systems before.
Why Union Furnaces and Boilers Fail Hard in Winter
Union's winters are unforgiving. The temperature swings from mild fall days to deep freezes stress every heating system, especially the ones that were installed when the houses were new. Most homes here were built in the early-to-mid twentieth century, and even well-maintained furnaces and boilers reach a point where the metal becomes brittle, seals crack, and burners lose efficiency.
Steam systems are common in Union's older neighborhoods. They're reliable when they work, but they corrode from the inside, and water leaks in the boiler or condensate returns become expensive fast. Forced-air furnaces accumulate rust in the heat exchanger and develop cracked flue pipes. Both types need air and fuel to reach the burner—clogged filters, bad ignitors, and corroded gas valves are routine failures when the heating season hits hard.
What to Do First When Your Heat Stops
Before you call, check the thermostat and confirm it's set to heat and above room temperature. Then look at your breaker panel or fuse box—a tripped breaker or blown fuse will stop an electric furnace or the control system on a boiler dead. Flip the breaker back on or replace the fuse, wait a few minutes, and listen for the burner to light.
If the furnace or boiler still won't start, don't tinker with the pilot light or the gas valve yourself. Call a heating specialist. If you hear the burner ignite but no heat is reaching rooms, check all your registers and vents—a closed damper or blocked ductwork can stop warm air cold. For steam systems, if the radiators stay cold and you hear no hissing, the boiler may not be generating steam. A specialist will need to check the water level, the pump, and the condensate line.

What Happens When the Pro Arrives
A local specialist will start by testing the thermostat and power, then listening to the furnace or boiler run. On a forced-air system, they'll check the air filter, inspect the heat exchanger for cracks, test the ignition and flame sensor, and verify that exhaust is venting outside safely. On a steam boiler, they'll check the water level, test the low-water cutoff, inspect the condensate return line, and confirm the burner is firing smoothly.
Most repairs happen on the spot—a new ignitor, a cleaned flame sensor, a patched leak, or a cleared condensate line. If the heat exchanger is cracked or the boiler is leaking internally, the specialist will explain your options: repair what you can or plan for replacement. You'll get a clear picture of what's wrong, what it costs to fix, and how long the system will likely last before you need a new one.
Choosing a Heating Pro in Union
Look for someone who has worked on Union homes and knows both steam and forced-air systems. Ask if they've repaired boilers and furnaces in your neighborhood—they should be familiar with the gas pressure, water hardness, and vent routing that's common on your block.
Confirm they can get to you during the heating season without a long wait. Describe what you heard when the heat stopped—no spark, no flame, no air flow, cold radiators—and they should ask follow-up questions to narrow down the problem before they arrive. A pro who listens and explains what they find builds trust fast.
