HVAC Services West Babylon NY | Call Flex Air

This is a common sign of an ignition system failure, often due to a dirty flame sensor, a faulty igniter, or issues with the gas valve. Our Long Island winters put extra strain on furnaces. A Flex Air technician can quickly diagnose the specific cause, perform a safe repair, and get your heat running reliably again to protect your home from the cold.

Absolutely. Duct leaks in your attic, basement, or crawlspaces force your HVAC system to work much harder, pushing conditioned air into unused spaces instead of your living areas. This leads to uneven temperatures, higher energy bills, and reduced airflow. We perform thorough duct inspections and sealing to improve your comfort and system efficiency throughout the year.

Our diagnostic service is a comprehensive check-up for your system. We'll test safety controls, measure airflow at vents, check refrigerant levels (for AC), inspect electrical components, and examine the heat exchanger and ignition system. We then provide a clear, honest explanation of any issues found and your repair options, with no-obligation estimates, so you can make an informed decision.
