Yes, our technicians are trained to service both oil and gas furnace systems. Many homes in Bristol County still use oil heat, while others have converted to natural gas or propane systems. We carry parts and have experience with all the major furnace brands and fuel types common in Massachusetts. Whether you have an older oil furnace or a newer high-efficiency gas unit, we can diagnose problems and perform the necessary repairs to get your system running properly.
The most frequent issues we encounter include faulty thermostats, dirty or clogged filters, ignition problems, and blower motor failures. Massachusetts winters put extra stress on heating systems, so we also see heat exchanger cracks in older units and issues with furnace controls that struggle with frequent cycling. Oil furnaces often develop problems with burner assemblies or fuel delivery, while gas furnaces may have issues with gas valves or venting. Many problems stem from lack of regular maintenance, which is why we recommend annual tune-ups to catch issues early.
Several factors help determine whether repair or replacement makes more sense. Age is important – furnaces over 15-20 years old often cost more to repair than they’re worth. Frequent breakdowns, rising energy bills, and uneven heating throughout your home are also signs that replacement might be the better investment. We’ll always give you honest advice about whether a repair will solve your problem long-term or if you’re better off upgrading to a newer, more efficient system. The decision ultimately depends on your budget, how long you plan to stay in your home, and the overall condition of your current furnace.
First, check your thermostat to make sure it’s set to heat and the temperature is set higher than the current room temperature. Check your circuit breaker to see if it’s tripped, and make sure your furnace filter isn’t completely clogged. If you have an oil furnace, check that you have fuel in your tank. If these basic checks don’t solve the problem, call us for service. Don’t attempt to repair the furnace yourself, especially if you smell gas or notice any unusual odors. Safety comes first, and modern furnaces have complex safety systems that require professional diagnosis and repair.
Yes, our Dempsey Comfort Club membership program includes regular maintenance visits designed to keep your furnace running efficiently and catch potential problems before they cause breakdowns. Members receive priority scheduling, annual tune-ups, and system inspections that help extend the life of their heating equipment. Regular maintenance typically includes cleaning, filter replacement, safety checks, and testing of all major components. This preventive approach saves money over time by avoiding emergency repairs and helping your furnace run more efficiently, which reduces your heating costs throughout the winter.
