Signs You Need Furnace Repair

When cold snaps drop temperatures below freezing, a working furnace is a must. That’s why it’s important to call Cornetta Bros. at the first sign of issues to receive the prompt attention you need. Common issues in Elmont include:

  • Insufficient heat: Your furnace may be struggling to properly heat your home if you’re experiencing cold spots or uneven temperatures.
  • Strange noises: Banging, rattling, squealing, and grinding all point to issues. Trust our team to determine if the cause is loose parts, motor issues, or airflow problems.
  • Rising energy bills: If your utility bills suddenly spike without any increased HVAC usage, your furnace may have problems that are causing it to work harder than it should.
  • Frequent cycling: Your furnace should not turn on and off quickly. If it doesn’t even complete a single heating cycle before shutting down, it could have an internal malfunction.
  • Weak airflow: Reduced airflow from your vents can be caused by a variety of issues, including clogged filters, blower problems, and duct issues.
  • Pilot light issues: Your furnace should have a strong and steady blue pilot light flame. If it doesn’t, always call a professional, as gas and combustion issues can be dangerous.
  • Power problems: A furnace that won’t turn on may have electrical failures or thermostat problems.

Our Furnace Repair Services 

At Cornetta Bros., we offer reliable furnace repairs that restore safe and efficient heat to your home. Our technicians will begin with troubleshooting and diagnostic testing, including a full inspection of your system to identify the cause of your problem. This includes testing electrical connections, examining the thermostat, checking airflow, and evaluating ignition or burner performance to pinpoint your issue.

Once we have a diagnosis, we can handle any component replacement or repair necessary to get your system up and running. Common furnace parts that may require replacement include ignitors, flame sensors, belts, thermostats, burners, and more. By addressing the failing components, our technicians can restore proper performance to your furnace while also preventing recurring breakdowns.

At the end of every repair service, we perform comprehensive safety and efficiency checks, including testing safety controls, confirming proper combustion, checking gas pressures and venting, and assessing airflow. These final checks give you peace of mind that your furnace is operating at peak performance and will continue to provide dependable comfort.

The Cornetta Bros. team knows not all furnace issues can wait for our normal business hours. That’s why we have available after-hours services to handle emergencies. Homeowners may require urgent attention for the following issues:

  • Breakdown in extreme cold: A lack of heat on the coldest day of the year can put your property and your family at risk. Our team can restore your heating quickly to help you avoid frozen pipes, illness, and more.
  • Gas odors: If you suspect a gas leak, shut off your furnace and evacuate your home immediately. Then, contact our team to provide the necessary repairs to protect you against fire and explosion.
  • Carbon monoxide issues: When your carbon monoxide detectors go off, it’s important to shut off your furnace and call for repairs so that our team can address combustion issues.
  • Burning smells: An electric furnace may produce burning smells if the wiring has overheated or if there is a serious electrical risk.
