Our Furnace Repair Process
Furnace repairs require a safety-first approach. Here is how we handle every call:
- Call and Describe Symptoms — When you call (919) 673-7667, describe what is happening — no heat, weak heat, strange smells, unusual noises, or the system cycling on and off. Our dispatcher asks targeted questions so our technician can arrive prepared.
- Safety Inspection First — Before diagnosing the reported problem, we check for carbon monoxide at the supply registers, inspect the heat exchanger for cracks, verify gas pressure at the manifold, and confirm all safety controls are functioning. Safety always comes first.
- Diagnosis and Upfront Pricing — We identify the root cause — whether it is a failed igniter, faulty flame sensor, blower motor issue, or control board problem — and present a clear, written repair estimate. You approve the cost before we begin.
- Expert Furnace Repair — Our NATE-certified technicians complete the repair using OEM or high-quality replacement parts backed by manufacturer warranties. Most furnace repairs are completed within one to two hours.
- Safety Verification — After the repair, we perform combustion analysis, recheck carbon monoxide levels, verify proper gas pressure, and confirm the system heats and cycles correctly. We will not leave until your furnace is operating safely.

Frequently Asked Questions
How much does furnace repair cost in Raleigh, NC?
Furnace repair costs in the Raleigh-Durham area typically range from $150 to $600, with the national average around $350. Simple fixes like a dirty flame sensor cleaning run $80-$150, while more complex repairs like a blower motor replacement can cost $400-$1,800 depending on the motor type. Emergency or after-hours service calls add a premium of $100-$150 to the base cost. The biggest factors affecting your final bill are the specific part that failed, your furnace’s age (older units often require harder-to-find parts), and whether the repair requires accessing difficult areas. Icy Hot Heating & Air Conditioning provides upfront pricing before any work begins — call (919) 673-7667.
Why does my furnace keep turning on and off repeatedly?
Frequent on-off cycling, called short-cycling, is a common furnace problem with several possible causes. The most likely culprit is a dirty or clogged air filter restricting airflow, which causes the heat exchanger to overheat and trip the high-limit safety switch. Other causes include a malfunctioning thermostat, an oversized furnace that heats too quickly and shuts down before completing a full cycle, a failing flame sensor, or blocked exhaust vents. Short-cycling wastes energy, increases wear on components, and can shorten your furnace’s lifespan significantly. Start by replacing your air filter — if that doesn’t resolve it, you’ll need a professional diagnosis to identify the root cause.
How much does it cost to replace a furnace ignitor?
Furnace ignitor replacement is one of the most common repairs, costing $100 to $300 including parts and labor. The ignitor part itself typically costs $15-$100 depending on whether you need a universal or OEM (original equipment manufacturer) replacement. Hot surface ignitors are the most common type in modern furnaces, and they have an average lifespan of 3-5 years. Signs of a failing ignitor include the furnace clicking but not lighting, the blower running without heat, or visible cracks on the ignitor element. This is a repair that should always be handled by a licensed technician, as it involves gas line safety and electrical connections.
What causes a furnace blower motor to fail?
Furnace blower motors typically fail due to age, overheating from restricted airflow, or bearing wear. A clogged air filter is the number one preventable cause — when the filter is dirty, the motor works harder to push air through the system and eventually burns out. Other causes include dust buildup on the motor itself, electrical issues like capacitor failure, and lack of lubrication on older motors with oil ports. Blower motor replacement costs $400-$1,800 depending on whether you need a basic PSC motor ($350-$800) or an energy-efficient ECM variable-speed motor ($600-$1,500). Icy Hot recommends changing your filter every 60-90 days to protect your blower motor.
Is it safe to run my furnace if it smells like burning?
A brief burning smell when you first turn on your furnace for the season is normal — it’s dust burning off the heat exchanger and usually dissipates within 30 minutes. However, persistent burning smells require immediate attention. An electrical or plastic burning smell may indicate overheating wiring or a failing blower motor. A metallic smell could suggest cracked or damaged internal components. A rotten egg or sulfur smell near a gas furnace means a potential gas leak — turn off the furnace immediately, evacuate your home, and call your gas company. Never ignore persistent unusual odors from your furnace, as they can signal fire hazards or carbon monoxide risks.
How long does a furnace repair usually take?
Most common furnace repairs take 1-3 hours to complete once a technician has diagnosed the problem. Simple fixes like replacing a flame sensor, ignitor, or thermocouple can be done in under an hour. More involved repairs like replacing a blower motor, control board, or inducer motor typically take 2-3 hours. The total timeline also depends on parts availability — common components are usually stocked on service trucks, but specialized or OEM parts may need to be ordered, adding 1-3 business days. At Icy Hot Heating & Air Conditioning, our trucks carry the most frequently needed parts so we can resolve the majority of repairs in a single visit.
When should I call for emergency furnace repair?
Call for emergency furnace repair immediately if you detect a gas smell (rotten egg or sulfur odor), hear your carbon monoxide detector alarming, see visible damage to the gas line or furnace housing, or notice water pooling around your furnace near electrical components. You should also call for urgent service if your furnace has completely stopped working during freezing temperatures, as pipes can burst when indoor temperatures drop below 32 degrees Fahrenheit. In the Triangle area, nighttime temperatures occasionally dip into the low 20s during January and February, making a non-working furnace a genuine emergency. Icy Hot offers 24/7 emergency heating repair — call (919) 673-7667 anytime.
