From furnaces that will not fire to air conditioners that have stopped cooling, here are the HVAC issues our clients call us about most.
A furnace that runs but delivers cold air usually has a failed igniter, a tripped high-limit switch from restricted airflow, or a gas supply issue preventing combustion. Running the blower without heat accelerates wear on the motor and does nothing to warm the home. We check the ignition sequence, flame sensor, limit controls, and gas valve to restore proper heating.
Ice forming on the evaporator coil or refrigerant lines is almost always caused by restricted airflow from a clogged filter, or a low refrigerant charge forcing the coil below its safe operating temperature. Running a frozen system drives up energy costs and risks permanent compressor damage. We assess airflow, refrigerant pressure, and coil condition before safely restoring operation.
A heat pump that stays stuck in heating or cooling mode typically has a failed reversing valve, a stuck solenoid, or a thermostat signal fault preventing the mode switch. Ignoring a stuck reversing valve risks overheating the compressor in the wrong operating mode. We test the reversing valve mechanically and electrically and replace the component if it cannot be restored.
A boiler that repeatedly drops below its operating pressure usually has a leak in the hydronic circuit, a faulty pressure relief valve that is venting too early, or a failed expansion tank that can no longer buffer system pressure changes. Left unaddressed, chronic low pressure causes the boiler to lock out and can lead to circulator pump damage. We test the system pressure, locate the leak or fault, and restore correct pressure regulation.
When the thermostat displays correctly but the system does not respond, the issue is usually a wiring fault at the control board, a failed transformer, or a thermostat that has lost its configuration after a power interruption. Continued attempts to force the system on can sometimes trigger a safety lockout that is harder to clear. We test the full control circuit from the thermostat to the board and repair or replace what has failed.
A single loud bang when a furnace fires is often caused by delayed ignition from a dirty burner, where gas builds up before the igniter catches it. This condition puts stress on the heat exchanger and can crack it over time, creating a carbon monoxide risk. We clean the burner ports, test ignition timing, and inspect the heat exchanger for stress fractures.
An HVAC system that runs for hours without reaching the thermostat setpoint often has a dirty heat exchanger or coil blocking heat transfer, a refrigerant charge issue reducing output, or excessive heat loss in the home's envelope overwhelming system capacity. Allowing this to continue increases energy consumption and accelerates compressor and motor wear. We test system output against the rated capacity and identify where the performance gap is occurring.
A CO alarm responding to a running furnace is a serious condition that should not be dismissed. The most common cause is a cracked heat exchanger allowing combustion gases to enter the circulated air supply. Evacuate the home and call the gas utility before calling for service. We perform a combustion analysis and full heat exchanger inspection before returning any system to service.
A heating or cooling system that has not been professionally serviced in two or more years is running with unknown wear on capacitors, heat exchangers, refrigerant levels, and blower components. Each of those conditions adds operating stress and raises failure risk. We complete a full-system assessment and restore the equipment to proper operating condition before the next peak season arrives.
I called thinking I needed a repair but the dispatcher asked a few questions and realized our system just needed its overdue maintenance visit. Saved us from paying for a service call we didn't need.
Gas Services Edmonton walked us through the numbers on repairing our 17-year-old furnace versus replacing it, and the math clearly favored replacement. Appreciated not being pressured either direction.
Our new system installation took an extra half day because of some unexpected ductwork issues found during setup. The team handled it well and kept us updated throughout, just wasn't the original timeline.
What started as a routine tune-up with Gas Services Edmonton turned into finding a refrigerant leak that hadn't caused any symptoms yet. Fixed on the same visit. Glad we didn't wait until it actually failed.
We've used Gas Services Edmonton for our spring maintenance, a furnace repair last winter, and eventually a full system replacement. Consistent honesty across all three visits made it an easy choice to stick with them.
I didn't understand why maintenance and repair pricing worked so differently until the technician explained it clearly. Made total sense once I understood the scope difference between the two.
