We provide same-day emergency furnace repair service in Wellesley. We understand that heating failures during Massachusetts winters aren’t just inconvenient – they’re potentially dangerous. Emergency calls get priority scheduling, and our technicians carry common replacement parts to complete most repairs in one visit. Our goal is to restore heat to your home as quickly as possible, not to schedule multiple appointments that leave you cold.
Yes, our technicians are trained and equipped to repair both oil and gas furnace systems. Many Wellesley homes still use oil heat, while others have converted to natural gas. The diagnostic process and repair approach differ between these systems, so experience with both is essential. Whether you’re dealing with a failed oil burner, gas valve problems, or issues with the blower motor, we have the expertise to handle it properly.
The decision depends on your furnace’s age, the cost of repairs, and how efficiently it’s running. Generally, if repair costs exceed 50% of a replacement cost, or if your furnace is over 15 years old and requiring frequent repairs, replacement makes more financial sense. However, a newer system with a single component failure is usually worth repairing. Our technicians provide honest assessments and won’t pressure you toward the more expensive option if repair is the smarter choice.
Furnace maintenance includes cleaning the heat exchanger, checking all electrical connections, testing safety controls, inspecting the flue pipe, and replacing filters. For oil systems, this includes cleaning the burner and checking fuel lines. Gas systems get combustion analysis and gas pressure testing. Our technician also checks for carbon monoxide leaks and ensures proper ventilation. Regular maintenance prevents most emergency breakdowns and keeps your system running efficiently, which reduces energy costs throughout the heating season.
Furnace repair costs vary based on the specific problem and parts needed. Simple fixes like replacing a thermostat or cleaning a flame sensor cost less than major component replacements like heat exchangers or blower motors. We provide upfront pricing before starting any work, so you know exactly what you’re paying. We don’t charge extra for evenings or weekends on emergency calls, and Dempsey Comfort Club members receive discounted rates on all repairs and priority scheduling.
All furnace repair work comes with a warranty on both parts and labor. The specific warranty period depends on the type of repair and components involved, but you’re protected if the same problem occurs again. We stand behind our work because we want customers who call us back for maintenance and future needs, not because something wasn’t fixed properly the first time. Warranty details are explained clearly before any work begins, so there are no surprises later.
