PROBLEM: A homeowner in Langhorne, PA contacted ECI Comfort after discovering her 30-year-old oil furnace had developed a cracked heat exchanger, which made the system unsafe to operate. Since the home already had natural gas available, she also wanted to explore switching away from oil to avoid the hassle and expense of future oil deliveries. With the furnace at the end of its lifespan, it was the right time to consider a full heating and cooling upgrade.
