Heating, Furnaces & Boilers
These articles cover the heating systems most common on Long Island: gas and oil furnaces, hot-water and steam boilers, and the thermostats that control them. They are for homeowners who want to understand a no-heat call before it happens, and most heating repairs are completed the same day; the cost depends on the failed component, the fuel type and how old the equipment is.
A large share of homes between Deer Park, Babylon and the Huntington line still heat with oil-fired boilers feeding baseboard radiators, while newer construction and many renovated homes run gas furnaces with ductwork. Each fails in its own way. Boilers lose pressure, circulator pumps seize and expansion tanks waterlog; furnaces trip on dirty flame sensors, failed igniters and blocked condensate drains on high-efficiency units. The first cold week of the season brings a wave of these calls, which is why fall maintenance matters so much here.
You will find step-by-step checks you can make safely, such as confirming the thermostat is calling for heat, resetting a tripped switch and replacing a clogged filter, along with explanations of the work that needs a professional: burner service, heat exchanger inspection, carbon monoxide safety and boiler replacement. We also explain when a repair is still worth doing on an older system and what to weigh when you replace it, including whether a cold-climate heat pump makes sense for your home.
If you have no heat right now, use the troubleshooting guides below and then call K2 at (631) 414-7141. We answer around the clock and dispatch heating technicians from our shop at 60 S 2nd St V in Deer Park.
