We carry common parts on the truck, and no-heat calls get priority.
How can you tell your furnace needs repair?
No heat at all
You set the thermostat and nothing happens. We check the system from the thermostat through to the burner to find where the breakdown is.
Blower runs, air stays cool
The fan moves air but the air never warms up. We check that the burners are lighting and the heat exchanger is getting hot.
Short cycling
The furnace starts, runs briefly, then shuts off, then repeats. We check what is causing the system to stop before it finishes a heating cycle.
Click then nothing
You hear a single click when the furnace tries to start, but the burners never light. We check the ignition sequence to find the failure point.
New rumble, squeal, or bang
The furnace makes a sound you have not heard before. We check the blower motor, the burner, and the cabinet for the source of the noise.
Burning or gas smell
You notice a smell of something burning or of gas near the furnace. We check for gas leaks and for anything burning that should not be.
Carbon monoxide alarm sounded
Your carbon monoxide detector has gone off. We check the furnace for combustion safety issues and measure carbon monoxide levels.
Thermostat never reaches its setting
The furnace runs for a long time but the house never gets to the temperature you set. We check the system's output against what the thermostat is asking for.
Furnace another company shut off
Another company turned your furnace off and left it that way. We inspect the unit to find the safety issue and explain what is needed.
Why do Utah furnaces fail so often?
At the Salt Lake City airport, heating degree days total 5,154; in Provo, 4,968; in Ogden, 5,508. According to the ENERGY STAR program, dirt and neglect are top causes of failure, and nearly half of home energy goes to heating and cooling. The industry maintenance standard states that maintenance is the homeowner's responsibility.
The ignition sequence
Amana explains that the control board starts ignition on a call for heat. Gas flows over the igniter, and a flame is drawn through the burners. The heat exchanger is where gas burns and heat is added. The inducer draws air, and the blower pushes air over the exchanger.[1]
The safety string
Per manufacturer wiring, the safety string includes the hot surface igniter, pressure switch, rollout limit with manual reset, and primary limit with auto reset. The standard calls for igniters inspected for cracks and resistance checked cold. The flame sensor is cleaned, and micro-amps are recorded.[2]
Carbon monoxide risks
The CPSC reports more than 200 deaths a year from non-fire carbon monoxide. About 1 to 70 ppm usually produces no symptoms, while 150 to 200 ppm can cause disorientation and possible death. The EPA notes 0.5 to 5 ppm in homes without gas stoves. The CPSC recommends alarms on every level and outside sleeping areas; Utah code requires alarms on each level.[3]
Who may work on it
Utah law requires a licensed HVAC contractor for installation, repair, or replacement, even on small jobs. Gas appliance work must be done by a trained and certified person. A gas line is considered part of the HVAC system.[4]

Is your furnace really condemned?
If another company says your furnace is unsafe, we offer a free second opinion. We back every safety claim with readings and photos. We are repair-first, and sometimes the other quote is right - we say so.
What does a proper furnace repair give you?
Combustion analysis
Combustion analysis measures the efficiency and safety of your furnace's burn. The readings are recorded. We perform this check on visits.
Gas pressure check
Inlet gas pressure is measured. Manifold pressure is measured and adjusted to the correct setting. If inlet pressure is low, the gas supplier is called.
Airflow verification
Airflow across the heat exchanger is measured and recorded. Heat rise is verified at the end of the repair.
Heat exchanger inspection
The heat exchanger is inspected for cracks, perforations, and bulges. If it is unsafe, the furnace is shut off and the owner is told immediately.
Parts on the truck
Common parts are carried on the truck. This includes igniters, flame sensors, and capacitors. Most repairs are finished the same visit.
Record
A record of readings and work done is provided. This record may be required as proof of maintenance for a warranty claim.
What furnace problems do we repair?
No ignition
We test the hot surface igniter cold and look for cracks or white spots when energized. If it fails, we replace it according to the industry maintenance standard.
Flame that drops out
The flame sensor and insulator are checked for cracks. We clean the sensor per the manufacturer and record micro-amps. We clean or replace the part as needed.
Pressure switch or inducer fault
Venting pressure switches are tested per the industry maintenance standard. The inducer motor is also tested. We clear the vent or replace the faulty part.
Blower that will not run
Capacitance is verified with a meter, and amp draw is compared to the nameplate. The blower wheel is checked to be tight and clean. We replace the capacitor or motor.
Limit that keeps tripping
The primary limit is auto reset; the rollout limit is manual reset per manufacturer wiring. Airflow across the exchanger is recorded per the industry maintenance standard. We find and fix the airflow problem.
Suspected heat exchanger crack
The heat exchanger is inspected for cracks, perforations, and bulges per the industry maintenance standard. An erratic flame with the blower on means it is unsafe; we shut it off and tell the owner immediately. We provide readings and photos and offer a free second opinion.

the price you sign is the price you pay - change orders require your approval before we do the work. Plus a free second opinion on any competitor's replacement quote (no blanket price-match - sometimes our honest answer is "take their deal").
What we won't promise
real-world comfort depends on duct condition, insulation, and infiltration, so we disclose those dependencies rather than guarantee a number. The 5.0 rating from 2,900+ reviews is the audit trail.
What homeowners ask about furnace repair
A repair visit starts with a diagnosis to find the problem. We perform a carbon monoxide and combustion check for safety. You receive the price in writing, and we wait for your approval before any work. After the repair, we verify the heat rise and give you a record of everything done.
The check uses a combustion analysis that is measured and recorded. The CPSC reports that levels from about 1 to 70 ppm usually cause no symptoms. The EPA notes 0.5 to 5 ppm is typical in homes without gas stoves. We provide readings and photos behind any safety claim we make.
Yes. If we find an unsafe condition, we shut off the equipment and tell you immediately. The heat exchanger is inspected for cracks, perforations, and bulges. We provide readings and photos to back up any safety finding. You can also get a free second opinion on our assessment.
We offer a free second opinion with our own readings. An unsafe condition means the equipment should be shut off and you should be told immediately. We are repair-first, but sometimes the other call is right. We will be honest about what we find.
We provide a workmanship guarantee on our labor. The price you sign is the price you pay. Manufacturer parts warranties, cover parts only and require a licensed contractor. We give you a record for any warranty claims.
We charge a flat diagnostic fee, not hourly billing. If you proceed with the repair, that fee is credited toward larger repairs but may be charged in addition for minor repairs or parts runs. You always see the price in writing before any work begins.
The parts most often replaced are the capacitor, flame sensor, hot surface igniter, inducer motor, and pressure switch. We carry common parts on the truck, so we can usually complete the repair during the same visit.
The ENERGY STAR program says to consider replacement if your furnace is more than 15 years old, needs frequent repairs, or causes rising bills. Other signs are rooms too hot or cold, excessive dust, or noise. We give you a written price for each path, and you choose.
We repair all furnace brands and carry common parts on the truck. As a licensed HVAC contractor under Utah law, any gas work is done by a certified person. We do not turn away any brand.
