Urgent furnace repair: no heat, strange noises, or won’t start
When the furnace goes down, comfort isn’t the only worry—think frozen pipes, sleepless nights, and safety concerns. We prioritize emergency calls with rapid response and smart diagnostics that cut out guesswork. Here are the issues we solve daily:
No heat / won’t turn on
Common culprits include a tripped breaker, dirty flame sensor, faulty limit switch, or thermostat issues. We run a step-by-step troubleshooting process—checking power, safeties, and airflow—to pinpoint the failure fast. Whether it’s a simple reset or a deeper electrical fault, you’ll see exactly what we found and why it matters.
Strange noises or burning smells
Banging, rattling, or squealing can escalate quickly. A squealing belt or unbalanced blower wheel becomes a bigger repair if ignored. Notice a burning smell? Sometimes it’s dust after downtime—but electrical odors need immediate attention. We inspect, clean, and correct the root cause so you can relax.
Pilot, ignition & flame sensor issues
Modern furnaces use hot-surface or spark ignition; older units may have a pilot. If the pilot won’t stay lit or the unit short-cycles, we’ll clean the sensor, test the ignition control board, and verify gas pressure. Expect professional-grade testing and a reliable restart.
Gas & electric furnace repair
We service natural gas and electric systems across all major brands. Whether the issue is fuel delivery, combustion, or electrical sequencing, our techs have the training and tools to fix it right the first time.
Gas furnaces: ignitor, pilot light, gas valve, flame sensor
Safe ignition and a reliable fuel path are non-negotiable. We test gas-valve performance/pressure, inspect the combustion chamber, and verify sensor feedback. From flame-sensor cleanup to gas-valve repair, we dial in clean combustion and dependable heat—without unnecessary parts swaps.
Electric furnaces: heating elements, sequencer, blower motor
If the unit runs but doesn’t warm, failed heating elements or a sequencer fault could be the cause. We test circuits, relays, and the blower-motor capacitor to restore proper staging and airflow.
Diagnostics & repairs we perform
Accurate diagnosis saves money. Our service includes fault-code reading, electrical testing, combustion analysis, and airflow measurements. When speed matters, count on same-day diagnostics followed by clear options you can trust.
Thermostat, short cycling & airflow problems
A miscalibrated thermostat or clogged filter can trigger short cycling and poor comfort. We verify sensor placement, recalibrate settings, and check duct static to rule out restriction. Our fix restores stable, efficient performance.
Blower motors, belts & bearings
Whirring or grinding? We check wheel balance, belt tension, and bearings. When needed, we perform blower-motor repair and precise reassembly so airflow is smooth, quiet, and efficient.
Heat exchangers & safety controls
Your heat exchanger and safeties protect your home. We test high-limit, rollout, and pressure switches to ensure safe operation. If we find a compromised exchanger or hazard, you’ll get an honest diagnosis and options that match your budget—we recommend replacement only when it’s truly necessary.
Transparent repair pricing & warranties
Clarity matters. That’s why we use flat-rate pricing—you’ll know the cost before work starts, with no hidden fees and options tailored to your needs.

You’ll see the service-call charge upfront and get a line-by-line explanation of findings. Prefer to approve repairs instantly? We can quote on the spot so you can decide with confidence.
