Our Heating Services

Keeping your home warm and comfortable is our specialty. We draw from many decades of experience to deliver excellent services. Cornetta Bros. offers more than boiler repair and furnace installations; we also handle oil-to-gas conversions, seasonal maintenance, and upgrades.

  • Furnace and boiler repair
  • Heating system installation
  • Safety and efficiency inspections
  • Emergency heating services

Our boiler repair services apply to natural gas, oil-fired, hot water, and steam systems. Some of the most common issues we repair in Oyster Bay include low pressure, pilot light failure, and ignition problems. For low-pressure issues, we locate leaks in pipes, radiators, or internal boiler components like the heat exchanger. When the pilot light malfunctions, we check the gas flow lines, ensuring the thermocouple or flame sensors are operational. If your boiler features an ignition system, we check the leads and electrodes for optimal functionality. If you need an upgrade or new installation, we work with you to choose the right system.

We service all major furnace types in Oyster Bay. Our service teams inspect heating system failures, inadequate temperatures, loud noises, and weak airflow situations. If your furnace is not operating, we check the thermostat sensors and connections. We check the flame sensor for dirt or damage, ensuring the motor gets adequate power. We can replace faulty components in the belt and blower mechanisms.

Our seasonal heating system inspections and maintenance work are crucial for preventing breakdowns at the most inconvenient times. We can inspect furnace and boiler systems for maximum safety and optimal energy efficiency. Our service teams can spot and repair small issues before they worsen, thus preventing heating emergencies and costly repairs.

Seasonal inspections also mitigate the risks of carbon monoxide leaks. Heating system tuneups can significantly improve energy efficiency and keep your monthly energy bills low. Our inspections include checking the heat exchangers for dangerous cracks; we also clean burners and test all safety controls. You can rely on Cornetta Bros. to keep your system running safely and efficiently. We strongly recommend scheduling inspections before the heating season begins in October.

When your Oyster Bay heating system fails during a bitter winter, we treat it as more than an inconvenience. In our service area, a boiler or furnace breakdown during a cold snap is a serious household emergency. At Cornetta Bros., we understand the gravity of heating emergencies better than anyone. Through all the decades of service in our community, we have restored heating comfort to thousands of residents during the coldest days. We have neighborly interests in ensuring you don’t suffer in the winter, and we act expediently to keep you warm. We train our service teams to handle emergency calls around the clock.
