Most heating and cooling failures trace back to a small set of components. Here are the problems our clients call us about most often.
This almost always points to a safety control responding to a real condition: a dirty flame sensor, a blocked pressure switch port, a restricted flue, or a tripped high-limit switch from restricted airflow. Ignoring it and resetting the system repeatedly can mask the underlying cause while the system accumulates fault lockouts. We diagnose the specific trigger and repair the source rather than simply clearing the fault code.
Warm air from a running air conditioner usually means the refrigerant charge is significantly low due to a leak, the compressor is failing to build pressure, or a reversing valve on a heat pump is stuck in heating mode. Adding refrigerant without finding the leak is a temporary fix that fails within the same season. We locate the leak source, repair it, and recharge to the correct specification.
A completely unresponsive HVAC system can stem from a tripped circuit breaker, a failed contactor, a dead control board, or a safety lockout triggered by an earlier fault. Each of these requires a different repair path and should not be assumed from a quick visual check. Our technicians test voltage at each stage of the control circuit to identify exactly where power is being lost.
Grinding from a blower motor or outdoor fan motor indicates bearing failure, which will lead to a seized motor if left unaddressed. A banging sound at furnace startup often points to delayed ignition causing a small gas buildup before the burners fire. Both conditions get worse with continued operation and should be repaired before they damage surrounding components.
A heat pump that runs without cycling off in moderate outdoor temperatures is usually either undersized for the space, low on refrigerant, or operating with a defrost control issue that is keeping it in heating mode. Constant operation accelerates compressor wear and significantly increases energy consumption. We test refrigerant charge, defrost timing, and outdoor temperature sensor function to identify the cause.
A carbon monoxide alarm responding to a running furnace is a serious condition that should not be dismissed as a false alarm without investigation. The most common causes are a cracked heat exchanger, a blocked or deteriorating flue, or backdrafting caused by pressure imbalances in the home. We perform a combustion analysis and heat exchanger inspection to identify the source and determine the appropriate repair.
A thermostat that is misreading temperature, failing to trigger the system, or displaying error messages may need calibration, wiring correction, or replacement. However, thermostat problems are also frequently misdiagnosed when the real fault lies in the system's control board or a wiring issue between components. We test the thermostat's output signals alongside the system's response before concluding it is the source.
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.
A system that turns on and off every few minutes without completing a full cycle is usually responding to a safety condition rather than reaching temperature. On a furnace, this often means a tripped high-limit switch from restricted airflow. On a cooling system, short cycling points to an oversized unit or a refrigerant issue. We identify the trigger and correct it at the source.
My AC had been repaired twice by another company and kept failing. Winnipeg Service Pros found a slow refrigerant leak at a joint the previous techs had missed. They repaired the leak, recharged the system, and it has been running perfectly through the whole summer. Finally solved.
Called in the morning with a furnace that would not ignite. The technician arrived by early afternoon, diagnosed a failed flame sensor within 20 minutes, and had the part replaced before dinner. The whole visit was under two hours and the price was exactly what they quoted on the phone.
The technician took his time to actually explain what was wrong with our heat pump and why. I had to wait an extra day for the part to arrive, but I appreciated that they were upfront about it rather than guessing. The repair held and the system has been running well since.
Winnipeg Service Pros found a cracked heat exchanger during what I thought was a standard repair call for reduced heat output. They showed me exactly where it was and explained the safety risk clearly. We replaced the furnace within the week and have been much more comfortable knowing the issue was handled properly.
I was expecting to be told I needed a whole new system. Instead the technician repaired the control board and capacitor, told me the rest of the furnace was in good condition, and said it should run fine for several more years with annual maintenance. Refreshingly straightforward.
The repair came with a 90-day parts and labour warranty, which made us feel secure about the investment. Everything worked perfectly after the visit and we ended up booking the annual maintenance as well. Winnipeg Service Pros will be our first call going forward.
