No heat
Heating and Furnace Repair in Sugar Hill, GA
If the furnace will not fire or keeps shutting down, we test it part by part until the heat stays on.
As the Rooms Cool Down
Winters here are short, but they bite. One hard freeze and a furnace that sat idle since spring suddenly has to carry the whole house, and that is when weak parts give themselves away. The inducer hums but the burners stay dark. The igniter glows and nothing follows. The flame catches, then drops out a few seconds later. Or the blower runs and pushes chilly air through every register. HVAC Sugar Hill repairs gas and electric furnaces in homes and small businesses, one failure at a time. Before you pick up the phone, glance at four things: the thermostat in heat mode with a setpoint warmer than the room, the service switch on the furnace flipped on, the breaker on, and a filter that is not caked with dust. A choked filter alone can trip the high-limit switch and shut the burners off. One rule outranks all of it. Smell gas? Leave the light switches and thermostat alone, get everyone outside and phone the gas company or 911 from the yard. When the house is safe again, we can find and fix whatever stopped the furnace.
Furnace Parts We Test and Repair
Nearly every no-heat call ends at one of these parts. We test them in order rather than guessing.
Igniters
Hot surface and spark igniters that crack or weaken leave the burners unlit. We test and replace them.
Flame sensors
A dirty or failing flame sensor shuts the gas off seconds after lighting. Cleaning or replacing it often restores heat.
Inducer motors
The inducer clears exhaust before ignition. If it fails or the pressure switch does not prove, the furnace will not start.
Limit switches
Overheating from poor airflow trips the high limit. We fix the airflow cause and the switch if it has failed.
Blower motors
A blower that will not run, runs weak or makes noise gets diagnosed, along with its capacitor.
Filters and airflow
Dirty filters and blocked returns cause many heating faults. We check airflow as part of every repair.
Electric heat strips
Heat strips in electric furnaces and air handlers, plus their sequencers and relays, tested and replaced.
Controls and wiring
Control boards, thermostat wiring and error codes read and traced to the real fault.
What Happens When You Call About No Heat
Safety first
We ask whether anyone smells gas or burning. If there is any doubt, we tell you how to stay safe before anything else. Then we note what the furnace is doing and how old it is.
Diagnose and price
The technician watches a heating cycle, reads any error codes and tests the parts in sequence. You hear the cause and the cost of the fix before work starts.
Repair and run
Once you give the nod, the part is swapped and the furnace is cycled several times while we watch temperatures and safeties, so the warmth lasts after we leave.
