24-HOUR SERVICE
Fast, honest gas and oil furnace repair, 24-hour emergency service, seasonal maintenance, and furnace replacement for Elwood and Huntington homeowners.
A furnace problem can turn a normal day into a stressful one quickly. Elwood Heating Inc. helps homeowners restore dependable heat with careful troubleshooting, clear explanations, and repairs focused on the actual cause of the problem. We service gas and oil furnaces, handle urgent breakdowns, perform seasonal maintenance, and replace systems that have reached the end of their useful life.
Our company was started in Elwood in 2006 by Frank DeLuca, a second-generation heating technician who wanted local homeowners to have a straightforward alternative to high-pressure sales companies. What began as a one-truck service business has grown into a close-knit team serving Elwood, Huntington, and nearby parts of western Suffolk County. When your furnace is not keeping up, making strange sounds, or refusing to start, our team is ready to help.
Frank DeLuca grew up near Elwood Road and learned the heating trade while working alongside his uncle during school breaks. After years of servicing homes throughout Suffolk County, he opened Elwood Heating Inc. with a used service van, a small set of tools, and a simple promise: diagnose carefully, explain the options plainly, and treat every home with respect. That approach still guides the company today.
Frank now serves as service manager and works closely with lead technician Marcus Reed, installation lead Luis Herrera, and operations coordinator Nina DeLuca. Marcus is known for patient diagnostics and has a particular interest in solving intermittent furnace problems. Luis oversees replacements and takes pride in clean mechanical-room work. Nina grew up in Elwood and keeps appointments, follow-ups, and customer communication organized. Together, the team brings a practical, neighborly approach to every service visit.

The cause may be a thermostat issue, ignition failure, fuel-supply problem, clogged filter, airflow restriction, or failed internal component. A technician should test the furnace rather than replace parts based on symptoms alone.
Yes. Elwood Heating Inc. services gas and oil furnaces found in homes throughout Elwood and Huntington. The diagnostic process and safety checks are adjusted to the equipment and fuel type.
Call promptly when the furnace will not produce heat during cold weather, repeatedly shuts down, smells like fuel, makes unusually loud noises, or triggers a carbon monoxide alarm. Leave the home and contact emergency services first if you suspect a gas leak or dangerous carbon monoxide condition.
Most furnaces should receive professional maintenance once each year, ideally before the heating season. Regular service can uncover wear, combustion concerns, airflow problems, and other issues before they cause a breakdown.
That depends on the furnace age, repair cost, efficiency, condition, and reliability history. We compare the immediate repair with the likely remaining life of the system so you can make an informed decision.
Yes. A heavily clogged filter can reduce airflow, increase operating temperatures, strain the blower, and cause the furnace to shut off on a safety limit. Filter replacement is simple, but recurring problems may indicate a larger airflow issue.
Yes. We evaluate the existing system, home size, ductwork, fuel type, venting, and comfort concerns before recommending equipment.
Our primary service area includes Elwood and Huntington, New York. Scheduling outside these areas may depend on location and availability.
