No two heating systems break the same way, and in Metairie homes the first question on any no-heat call is what kind of equipment we are dealing with. Furnaces most often stall on an oxidized flame sensor. The burners fire, the sensor fails to confirm the flame, and after three attempts the control board closes the gas valve and locks the system out. Cracked hot surface igniters, sticking pressure switches, plugged condensate traps on high-efficiency units, and tired blower motors round out the usual list. Heat pumps have their own failure patterns. A defrost cycle that underperforms lets ice build up on the outdoor coil, a bad reversing valve traps the system in cooling mode, and a dead outdoor unit hands the whole load to the electric backup strips, which cost several times as much to run.
Guessing gets expensive on a cold night, so Metairie HVAC treats every heating call as a diagnosis first and a repair second. Our experienced technicians measure before they replace anything: microamp flame signal, igniter resistance, pressure switch response to actual inducer draft, capacitor and motor readings, plus charge and defrost checks when the system is a heat pump. On gas equipment, safety checks are built in, not an add-on. Gas connections are leak-tested, the heat exchanger is inspected, and venting is verified, because warm air from an unsafe furnace is not a fix.
Furnace, heat pump, air handler, boiler, or ductless unit, and whatever brand is on the nameplate, we service it. Stocking igniters, flame sensors, capacitors, inducer motors, and blower motors on every truck means heat usually comes back on the first trip. And if a repair no longer makes sense for aging equipment, we will be honest about that and lay out the options with real numbers. Call (504) 531-6049 for heating repair anywhere in Metairie, and an experienced technician will head your way today.

Warning Signs for Heating Repair
Catching these issues early helps you avoid costly problems and protect your property. These are the signals our technicians see most often when a problem is underway:
- Cold rooms in one part of the house while others are comfortable
- Energy costs climbing even though the house feels colder
- The system starting and stopping every few minutes without warming the house
- Banging at startup caused by burners lighting late
- Cold air, or no air at all, when the thermostat calls for heat
- A heat pump's outdoor unit encased in frost or ice
- Strange smells from the vents, especially rotten egg or burning
- Clicking and failed ignition attempts before the furnace gives up

Why Professional Heating Repair Matters
Combustion is what makes heating repair different from the rest of home comfort work. Delayed ignition booms unburned gas inside the heat exchanger and stresses the metal each time it happens. A cracked exchanger can leak combustion gases into the air your family breathes, and a flue that stops drafting pushes carbon monoxide into the living space instead of outdoors. None of these problems announce themselves to someone without training and instruments. Diagnosis has its own traps as well. Short cycling can point to a failing limit switch or to a furnace protecting itself from a clogged filter, and cleaning a fouled flame sensor without asking why simply sets up the next lockout.
That is why Metairie HVAC does not guess. Our technicians read flame signal on a meter, look at the heat exchanger directly, confirm the flue is drafting, and compare temperature rise to the data plate to make sure the blower speed fits the burner. On heat pumps we check defrost controls, sensors, and the reversing valve before blaming the compressor, and we find out whether the electric backup heat has been running unnoticed and driving up your costs. Nothing is called fixed until it has run a full cycle and proven itself safe and correct, because your family's warmth and safety depend on it.
Our Heating Repair Process
Every visit follows a step-by-step method refined over years of hands-on experience. Here's exactly how the heating repair process unfolds:
Testing & Safety Check
We pull the fault codes, then verify: flame signal, igniter resistance, pressure switch operation, motor and capacitor health, and charge and defrost on heat pumps, with gas connections leak-tested as standard.
Straight Answers & a Firm Price
We show you what failed and why, and give a firm price before work begins. If a cracked heat exchanger or dead compressor changes the math toward replacement, we say so plainly.
The Repair Itself
Because we stock igniters, flame sensors, pressure switches, capacitors, and motors, most repairs are finished on the first visit, and your home is warming up before we pack up.
Final Testing
Before we leave, the system runs through full heating cycles while we measure temperature rise against the data plate, confirm safe combustion and venting on fuel-burning equipment, and check each safety control.

A few simple habits now, like regular filter changes and seasonal tune-ups, can add years to your system's life. Start with these practical measures our team relies on:
- Never store paints, solvents, or chlorine products near the furnace; their vapors corrode the burners
- Call about booming at startup or new rattles right away, while the fix is still inexpensive
- Give the outdoor heat pump unit open space, free of snow drifts and plantings, so it can defrost
- Test carbon monoxide detectors monthly and put one on every level of the home
- Replace filters monthly through the heating season to keep airflow strong and the heat exchanger from overheating
- Schedule a professional tune-up every fall before the first cold snap finds the weak parts
- Leave open space around the furnace so the burners can draw enough combustion air
DIY vs. Professional Heating Repair
Online tutorials may help in a pinch, yet lasting repairs and code-compliant installations usually depend on professional methods and trained technicians. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| CO Safety | An unseen hazard never gets tested | Exchanger inspected, flue draft confirmed |
| Diagnosis | Parts swapped on a hunch | Flame signal and components metered |
| Gas Connections | A loose fitting goes unnoticed | Every joint checked with a leak detector |
| Heat Pumps | An iced coil blamed on the compressor | Defrost controls and reversing valve tested |
| Root Cause | Symptom treated, problem left behind | Cause found, not just the symptom |
| Final Testing | It lit once, good enough | Full cycles run, temperature rise confirmed |
