Gas furnaces, homes and shops
When the furnace will not light, blows cold or keeps shutting itself off, we find the reason and fix it, so the house is warm again before the cold snap passes.
We answer the phone or call back the same working day. Monday to Saturday, 7 am to 6 pm.
The repair
Furnace repair on residential and commercial gas furnaces finds why the furnace will not light, blows cold air or shuts itself off, and then fixes that cause.
Most of the year the heat sits unused here, so when it is finally asked to run, small faults show up all at once: an igniter that has worn out, a flame sensor coated over, a blower that drags, a vent that is blocked. Each has a plain check, and the check names the part that failed instead of guessing at it.
We quote the whole repair before we start, with no surprise charges after, and we clean up when the work is done.

Know the signs
These are the signs that call for furnace repair, and any one of them is worth a call before the next cold night.
A yellow flame matters most. Read the carbon monoxide note before anything else.
No heat
The thermostat calls for heat and nothing happens, or the burners try to light and give up.
Cold air from the vents
The blower runs but the burners never come on, or they light and drop out a moment later.
The furnace keeps shutting off
It starts, runs briefly and stops, over and over. The trade calls a system that keeps turning on and off "short cycling".
New banging or squealing
A bang as the burners light or a squeal from the blower is a noise the furnace did not make last winter.
A yellow burner flame
A healthy gas flame burns blue. A lazy yellow one points at a burner or venting problem that needs a look right away.
From the call to a warm house
The technician works through the ignition, the flame sensor, the blower and the venting, repairs the part that failed, then tests the furnace through a full cycle.
Ignition
The igniter or pilot is checked first, since a furnace that will not light usually stops right here.
Flame sensor
The sensor proves the flame is lit. A coated rod makes the furnace shut the gas off, so it is cleaned or replaced.
Blower
The blower motor and wheel are checked for the drag and noise that leave rooms cold and the cabinet running hot.
Venting
The flue and vent are checked for a clear path out of the house before the furnace goes back into service.
Repair and full cycle
The failed part is repaired or replaced, then the furnace runs through a full cycle to confirm it heats properly before the technician leaves.
We quote the whole job before we start, with no surprise charges after.
A furnace that burns gas calls for working carbon monoxide alarms on every level of the home, and a headache or dizziness while the heat runs means getting everyone outside to fresh air first.
A yellow flame, a blocked flue or a loose vent pipe can let combustion gases back into the rooms, and those are the faults the venting check in a repair is there to find. The U.S. CPSC Carbon Monoxide Information Center covers where the alarms go and the symptoms to watch for.
A furnace in Biloxi can sit idle through a long cooling season, so it is best tested and cleaned before the first cold snap rather than on the first cold night.
Months of damp air and dust settling on burners, a sensor and a blower that never move wear on a furnace more than hours of use do. A check in the fall finds the tired igniter or the dirty sensor while it is still a small fix.
Related jobs each have their own page, and a new system is covered under AC installation.
When a furnace turns out to be past saving, or the heat in the house comes from a heat pump or electric heat strips rather than gas, these pick it up:
