When your furnace breaks down, it always seems to happen on one of those bitterly cold January days we often face here on Long Island.

When these problems arise, trust T.F. O’Brien for fast, reliable furnace repair services. With our 24/7 emergency line, help is always just a phone call away. Restoring warmth to your home is our top priority.

Expert Furnace Repairs for Long Island Homes

When your gas furnace malfunctions, our expert technicians begin by troubleshooting based on the symptoms you report. Using advanced diagnostic tools, we conduct a thorough inspection to pinpoint the issue. Our process typically starts with the furnace filter since a clogged filter is often the culprit behind poor performance. From there, we assess key components such as the ignition system, flame sensor, thermocouple, and gas valves—all of which can become dirty or fail over time.

We also evaluate the furnace’s control board and thermostat to ensure proper operation. The blower and inducer motors are carefully inspected, and we use a multimeter to check for electrical continuity in the motor windings. With years of experience serving Long Island homeowners, our team prides itself on quick and accurate diagnostics to get your heat back on.

Restoring Your Furnace to Peak Performance

Once we identify the problem, our technicians perform the necessary repairs to restore warmth to your home. For ignition system issues, we replace worn-out components to ensure reliable startup. If your furnace cycles on and off without maintaining warmth, a simple flame sensor cleaning or replacement often resolves the issue.

For motor-related problems, we inspect capacitors, lubricate moving parts, and replace faulty motors to restore optimal airflow. Blocked ducts and vents are another common issue, and we ensure these are cleared to prevent obstructions. Whatever the problem, you can count on us to find a solution and restore comfort to your home.

Comprehensive Final Checks

Before we finish, we perform a series of final checks to ensure your furnace operates flawlessly. We verify smooth startup and shutdown, check for gas leaks or unusual smells, and ensure proper airflow and venting throughout your home. We also inspect and adjust your thermostat to maintain your ideal comfort level.

To guarantee your satisfaction, we complete a full heating cycle test, providing you with confidence that your furnace is working at its best. Before leaving, we’ll offer maintenance tips to help keep your system in top shape until your next service. Of course, we’ll clean up thoroughly to leave your home just as we found it.
