Furnace ignition failures are a common winter issue in our area, often due to a dirty flame sensor, a faulty igniter, or issues with the gas valve. For your safety, we recommend turning off the furnace at the thermostat and the power switch. Call us for 24/7 emergency service. Our technicians are experienced with the specific models common in Mastic Beach homes and can quickly diagnose and resolve the ignition problem to restore your heat safely and efficiently.

Our thorough plumbing inspection is designed to give Mastic Beach homeowners a clear picture of their system's health. We check for leaks, test water pressure, inspect pipes for corrosion or damage, examine fixtures, and assess your water heater's condition. This is especially valuable before buying a home, during renovations, or as preventative maintenance to avoid unexpected issues. We provide a detailed report and honest recommendations, with no obligation for further service.

Regular maintenance is key to system longevity, efficiency, and preventing mid-season breakdowns. For your heating and cooling systems, our maintenance service includes cleaning critical components like coils and burners, checking refrigerant levels, lubricating moving parts, testing safety controls, and inspecting the air handler fan—a common point of failure. This proactive care helps your system run smoothly, can lower energy bills, and allows us to spot small issues before they become costly repairs or emergencies.
