What is furnace repair?
Furnace repair is the process of diagnosing and fixing issues that prevent your heating system from operating safely and efficiently. A certified technician tests ignition, airflow, electrical components, and safety controls, then restores proper heat with the right replacement parts and verified performance checks.

A furnace blowing cold air is most often caused by a dirty air filter, a thermostat set to FAN instead of AUTO, a pilot light or ignition failure, or an overheating system that trips the high-limit switch. Check these before calling for service.
Replace the filter and restart the system. A blocked filter restricts airflow, causing the furnace to overheat and blow cold air as a safety measure.
Switch the fan setting to AUTO so the blower only runs when the furnace is actively heating. FAN mode circulates unheated air.
For standing-pilot systems, relight the pilot. For electronic ignition, check for error codes on the control board. A faulty flame sensor or ignitor may need replacement.
The limit switch shuts off the burner when the furnace overheats. Causes include blocked vents, a failing blower motor, or dirty heat exchanger. This requires professional diagnosis.
Verify the gas valve near the furnace is fully open. Check if other gas appliances work. If you smell gas, leave the home and call your gas company immediately.
Heated air may be escaping through disconnected or damaged ducts before reaching your rooms. A duct inspection can identify and seal leaks.
Catching problems early prevents expensive breakdowns and safety hazards. If you notice any of these signs, schedule a $79 diagnostic before the issue worsens.
Usually caused by a dirty air filter, thermostat set to FAN instead of AUTO, a failed ignitor, or a tripped high-limit switch. Check the filter and thermostat settings first.
Banging indicates a delayed ignition or loose internal part. Screeching suggests a failing blower motor bearing. Rattling often means loose panels or ductwork. Turn off the system if you hear metal-on-metal grinding.
A healthy pilot flame is steady and blue. A yellow, orange, or flickering flame indicates incomplete combustion — potentially producing carbon monoxide. This requires immediate professional inspection.
Often caused by a dirty filter, overheating, a malfunctioning flame sensor, or a faulty thermostat. Short cycling wastes energy and accelerates wear on the heat exchanger and ignition system.
Could be a failing thermostat, but more often indicates an undersized system, duct leaks, a dirty blower motor, or a heat exchanger losing efficiency. A diagnostic determines the root cause.
A faint burning smell on first startup is normal (dust burning off). Persistent burning smells suggest wiring issues or overheating. If you smell rotten eggs (gas additive), leave the home immediately and call your gas company.
A CO alarm near your furnace is a serious emergency. Evacuate immediately, call 911, and do not re-enter until cleared. Cracked heat exchangers, blocked flues, and backdrafting are common causes of CO leaks from furnaces.
A furnace losing efficiency due to a failing blower motor, dirty burners, a cracked heat exchanger, or clogged filter runs longer and harder, increasing energy costs by 20–40% or more.
Heated air may be escaping through disconnected or leaking ducts, or the blower motor may not be pushing enough airflow. Duct sealing and a blower motor inspection can resolve this.
Rust on the furnace cabinet, flue pipe, or visible cracks near the heat exchanger area indicate age-related deterioration. A cracked heat exchanger is a safety hazard requiring immediate professional evaluation.
Try these steps first — they solve about 20% of furnace issues without a service call. If the problem persists, call (702) 567-0707 for same-day diagnosis.
Try these first:
Call a pro when:
If the thermostat calls for heat but the furnace does not ignite, or if you see a flashing error code on the control board — likely a failed ignitor, flame sensor, or gas valve issue
Try these first:
Call a pro when:
If the burner ignites briefly then shuts off, or if the blower runs but no heat is produced — this points to a faulty flame sensor, gas valve, or cracked heat exchanger
Try these first:
Call a pro when:
Immediately for grinding, screeching, or repeated banging — running a furnace with a failing blower motor bearing causes heat exchanger damage and safety risk
Try these first:
Call a pro when:
If replacing the filter does not fix it — likely a failing flame sensor, overheating limit switch, or oversized system issue that requires professional diagnosis
Gas furnace safety is non-negotiable. Understanding these warning signs can protect your family from carbon monoxide poisoning and fire hazards.
CO is odorless and colorless. Symptoms of exposure include persistent headaches, dizziness, nausea, confusion, and flu-like symptoms that improve when you leave the house.
The color of your furnace burner flame tells you whether combustion is clean and efficient, or potentially dangerous.
The heat exchanger separates combustion gases from your home's air supply. A crack allows carbon monoxide to enter your ductwork and living spaces.

How much is the furnace repair diagnostic?
Our furnace diagnostic is typically $79 in Las Vegas and includes a full check of ignition, airflow, electrical components, and safety controls. After diagnostics, you get clear options and upfront pricing before any repair begins.
What are the most common furnace repairs?
Most repairs involve ignition systems, flame sensors, blower motors, thermostats, or airflow problems. We diagnose the root cause so the fix is reliable and prevents repeat failures.
What is the $5,000 rule for furnace replacement?
Multiply the furnace's age in years by the repair cost. If the result exceeds $5,000, replacement is usually the better investment. For example, a 12-year-old furnace needing a $450 repair equals $5,400 — replacement makes more financial sense.
How long do furnaces last?
Gas furnaces last 15 to 20 years on average. Electric furnaces last 20 to 30 years. Annual professional maintenance, regular filter changes, and proper installation are the biggest factors in furnace longevity.

Most gas furnaces last 15 to 20 years, while electric furnaces typically last 20 to 30 years. The average furnace lifespan is 16 to 20 years with regular annual maintenance. In the Las Vegas Valley, furnaces often exceed the national average lifespan because they run fewer total hours due to shorter, milder winters.
Use these industry-standard rules to decide:
Yes. A cracked heat exchanger can leak carbon monoxide into your home — an odorless, colorless gas that causes headaches, dizziness, nausea, and can be fatal. If a technician suspects a heat exchanger crack, the furnace should be shut off immediately. Repair costs $1,500–$3,500, but replacement is usually more cost-effective for furnaces over 15 years old.
