Furnace Repair in Suffolk County, NY

What to Do When Your Furnace Stops Working 

When a furnace breaks down, it often happens on one of those cold and frosty January days we experience here on Long Island. Your furnace may give you early warning signs that it needs repair, such as short cycling (turning on and off rapidly), blowing cold air instead of warm, emitting strange smells, or it might suddenly stop working altogether. When this happens, call T.F. O’Brien for fast and reliable furnace repairs. Our 24/7 emergency phone line is available for urgent assistance. Our top priority is to get your furnace running again as quickly as possible to keep your household warm.

Expert Furnace Troubleshooting for Long Island Homes

When your gas furnace needs repair, we start the troubleshooting process based on the symptoms you’re experiencing. Our technicians conduct a thorough inspection using their expertise and diagnostic tools to quickly identify the problem. We check the furnace filter first, because clogged filters are often the cause for furnace malfunctions. From there, we inspect other key components, such as the ignition system, flame sensor, thermocouple, and gas valves, all of which can become dirty or malfunction over time.

We also test the furnace’s control board and the thermostat system for proper operation. Motors, such as the blower and inducer motors, are inspected, and we use a multimeter to check motor windings for continuity. Our team of technicians have years of experience troubleshooting gas furnaces on Long Island. We pride ourselves on finding the cause of your heating problem right away. 

Getting Your Gas Furnace Up and Running

Once we’ve diagnosed the issue, our team of technicians will begin any repairs needed to get warm air flowing back into your home. If the problem is the ignition system, we’ll thoroughly inspect and replace any defective components. For furnaces cycling off and on without maintaining warmth, a simple flame sensor cleaning or replacement will usually solve the problem.

We address any motor issues by checking capacitors, lubricating parts, and inspecting motor bearings. If we find a motor isn’t functioning properly, we’ll replace it with a new one designed for your furnace. Blocked ducts or vents are another common issue that we check, ensuring nothing is obstructing proper airflow. No matter what the issue, we’ll find a solution.

Final Furnace Checks and Clean-Up

Before leaving, we make sure your heating system is running smoothly. We verify that the furnace starts up without any unusual noises or ignition issues and that it shuts off properly. We also check for any gas leaks or odd smells and ensure your home has proper airflow and venting. Your thermostat will be thoroughly inspected to ensure it’s properly configured to keep your home comfortable all winter long.

Our final step is completing a full heating cycle test to feel like we have completed the work to your satisfaction and ours. We’ll give you any information you’ll need for maintaining your furnace until your next service appointment. As always, we clean up thoroughly before we leave to make sure we respect you and your home.
