No heat, weak heat, cold air
Furnace and Heating Repair for Snellville Homes
Clicking without flame, lukewarm air or a heater that keeps quitting: testing finds the bad component and the repair carries a price before work.
A Cold House Usually Traces Back to One Part
Winters around here are mild for long stretches and then a hard freeze arrives overnight, which is exactly when a furnace that has been sitting idle decides to act up. Inside a gas furnace, ignition is a chain of handoffs. A small fan purges the vent, a switch verifies that draft, a hot surface igniter heats up, gas flows to the burners, a sensor confirms there is flame, and only then does the main blower send warmth through the ducts. Break any link and the control board aborts and retries, which explains the start, brief run and shutdown you might be hearing. Electric models have no burner at all; their weak points are the resistance coils and the switches that bring them on in stages. We test each step in order until the failed component is clear, whether that is a cracked igniter, a dirty flame sensor, a weak inducer, a high-limit trip caused by a dust-packed filter or a tired blower motor. The faulty part and its replacement cost are explained to you first. One safety note comes ahead of everything else: if there is a gas smell, get everyone outdoors immediately and phone the gas company or 911 from there. Do not try to relight the furnace or flip any switches. Once the gas company has cleared the home, we can come find out why the smell appeared.
Usual Suspects in a Cold House
The usual suspects when a furnace misbehaves.
Igniters
Hot surface igniters checked for cracks and resistance, and replaced when they no longer glow reliably.
Flame sensors
Cleaned or replaced when a coated sensor makes the burners shut off seconds after lighting.
Inducer motors and pressure switches
Tested when the furnace hums but never gets to ignition.
Limit switches
Checked along with the airflow problems, like dirty filters or closed vents, that cause them to trip.
Blower motors
Amperage, capacitors and bearings tested when air barely moves or the blower will not start.
Electric heat elements
On electric units, the elements, sequencers and relays that stage the heat get a meter on them.
Filters and safety checks
A clean filter goes in and each safety device is proven before we hand the heat back to you.
How a Furnace Repair Visit Runs
Tell us what the furnace is doing
Clicking, a brief flame that goes out, cold air or nothing at all. Those details point to the likely part before the technician arrives.
Test the sequence and price the fix
Each step of the startup sequence is tested to find where it breaks down. You get the repair and its cost before work begins.
Repair and confirm safe operation
With the new part in, we let the furnace fire again and again, watching flame, temperature rise and each safety device.
