Heating Services in Glen Cove
Family-Owned Heating Service in Nassau County Since 1973
Glen Cove winters can push temperatures into the mid-20s, and when that happens, your heating system isn’t optional. L. Graziose Plumbing Heating & Cooling has been keeping Nassau County homes warm since 1973, and today the same family, now in its third generation, is still the one answering your call. Founded by Larry and Marie Graziose and now led by brothers Robert and Michael alongside Daniel, we bring more than 50 years of residential heating knowledge to every job. Our licensed technicians work on all makes and models, and we back that up with same-day service and 24/7 emergency heating support for the moments that can’t wait.
That continuity matters. A large regional chain cycles through technicians and service managers. We don’t. The family that serviced heating systems in Glen Cove in 1973 is the same family running the trucks today, with the same commitment to courtesy, integrity, and professionalism on every job.

How Often Should My Heater Be Serviced?
We recommend having your heater professionally serviced once a year to help it run safely and efficiently through winter. Early fall is the ideal window, before you need to lean on the system for the season. Through our Preferred Service Plan, our licensed technicians can identify small mechanical issues before they turn into expensive, middle-of-the-night emergencies.
Even with regular maintenance, parts wear out. If you notice any of the following signs, call our heating company in Glen Cove:
- Unusual noises - Banging, whistling, or grinding sounds can point to delayed ignition, restricted airflow, or a failing motor and are worth having a technician evaluate.
- Rising energy bills - If your heating costs are climbing but your usage hasn’t changed, your system may be working harder than it should to hold the temperature you’ve set.
- Short cycling - A heater that turns on and off repeatedly without warming the house can signal a mechanical or electrical fault. The added stress can accelerate wear on system components.
- Yellow pilot light - For gas systems, a healthy pilot light burns blue. A yellow or flickering flame can indicate incomplete combustion or the presence of carbon monoxide and warrants immediate attention.
- Uneven heating - Rooms that stay cold while others overheat can suggest your system is struggling to distribute heat effectively throughout the home.
