Furnace Repair Services in Plano, TX

There are several potential causes. The most common ones we see in Plano include a malfunctioning flame sensor that shuts down the burners shortly after ignition, a failed igniter that prevents the burners from lighting at all, an overheating furnace that triggers the high-limit safety switch, or simply a thermostat set to "fan on" instead of "auto." Our technicians work through each possibility systematically to find the root cause.

Age, repair history, and the severity of the current problem are the key factors. A furnace under 12 years old with a straightforward repair - like a new igniter or flame sensor - is almost always worth fixing. A furnace approaching 20 years with a cracked heat exchanger or a history of repeated breakdowns may be a better candidate for replacement. We will give you a candid, pressure-free assessment based on your specific circumstances.

It can be. A furnace with a cracked heat exchanger can potentially leak carbon monoxide into your home. A furnace with a gas valve issue can create other safety concerns. If you smell gas near your furnace, hear your carbon monoxide detector alarm, or see visible damage, shut the system off and call us immediately. Safety is always our first priority.

A comprehensive furnace tune-up from Trotter Air Services includes cleaning the burners and flame sensor, testing the ignition system, inspecting the heat exchanger for cracks or corrosion, checking the blower motor and capacitor, verifying gas pressure and temperature rise, testing all safety controls, inspecting the flue and venting, and replacing the air filter. This thorough inspection catches problems before they become emergencies.

We recommend professional furnace maintenance once a year, ideally in the early fall before you need to run the system regularly. Since Plano furnaces often sit idle for much of the year, that fall tune-up is especially important for clearing accumulated dust, testing components that have not operated in months, and verifying that everything is ready for the heating season.

There are a few safe things you can check: make sure the thermostat is set to heat and the temperature is set above the current room temperature, check that the furnace power switch is on, verify that the circuit breaker has not tripped, and check whether the air filter is extremely dirty and restricting airflow. Beyond these basic checks, furnace troubleshooting should be left to a licensed professional - gas-burning equipment requires trained hands.

Short-cycling - when the furnace turns on and off repeatedly in rapid succession - is typically caused by an overheating condition. A dirty air filter, a blocked return air vent, a malfunctioning blower motor, or a faulty high-limit switch can all trigger short-cycling. In some cases, an oversized furnace can also short-cycle because it heats the space too quickly and shuts off before completing a proper heating cycle. We identify the specific cause and correct it.

That burning smell when your furnace first fires up for the season is usually dust burning off the heat exchanger and burners. It has accumulated while the system sat dormant through the summer months, and it typically dissipates within an hour or two of operation. However, if the smell persists, smells like rotten eggs (a sign of a gas leak), or is accompanied by visible smoke, shut the system off and call us right away.
