More Than Just Emergency Fixes

Emergency furnace repair is just one part of what we do. We handle routine maintenance that catches small problems before they become expensive ones. Regular furnace servicing keeps your system running efficiently and extends its lifespan significantly.

Whether you have an older oil furnace that needs specialized attention or a newer gas system with electronic controls, our technicians have the experience to work on it properly. We stock parts for the brands and models common in this area, which means faster repairs and less time without heat.

Our Dempsey Comfort Club gives you priority scheduling and helps you stay on top of maintenance. It’s designed for homeowners who want to avoid emergency breakdowns and keep their heating costs predictable year after year.

How quickly can you respond to a furnace emergency in Onset?

We prioritize emergency calls, especially during cold weather when you need heat restored quickly. Response times vary based on current demand and weather conditions, but we understand that furnace breakdowns can’t wait. When you call with an emergency, we’ll give you a realistic timeframe and keep you updated if anything changes. We keep trucks stocked with common parts to handle most repairs on the first visit, which gets your heat back on faster than companies that need to order parts and come back later.

Do you work on both oil and gas furnaces?

Yes, our technicians are trained to service and repair both oil and gas heating systems, plus other types of furnaces you’ll find in Plymouth County homes. Each fuel type has its own maintenance requirements and common issues, so we keep the right tools and parts for both. Oil systems often need different attention than gas units, especially in older homes where the equipment has been running for decades. We also work on electric furnaces and heat pumps when those are part of your heating setup.

What are signs my furnace needs professional repair?

Strange noises like banging, squealing, or rattling usually mean something needs attention before it breaks completely. Uneven heating where some rooms are warm and others stay cold often indicates airflow or distribution problems. Higher than normal energy bills can signal that your system is working harder than it should. If you smell gas, oil, or burning odors that seem unusual, shut off your system and call us immediately. Yellow flames instead of blue on gas furnaces, frequent cycling on and off, and difficulty getting your system to start reliably are all signs that professional service can prevent a complete breakdown.

Should I repair or replace my old furnace?

This depends on the age of your system, the cost of repairs, and how efficiently it’s been running. Generally, if your furnace is over 15 years old and needs expensive repairs, replacement might make more sense financially. However, well-maintained systems can often run reliably for 20+ years with proper care. We’ll give you honest advice about whether a repair makes sense or if you’re better off investing in a new system. Factors like your home’s insulation, ductwork condition, and your long-term plans for the property all play into this decision.

How often should I have my furnace serviced?

Annual maintenance is the standard recommendation for most heating systems, ideally scheduled before the heating season begins. Oil furnaces typically need more frequent attention than gas systems due to how the fuel burns and the components involved. If your system is older or has had reliability issues, twice-yearly service can catch problems early and keep things running smoothly. Regular maintenance includes cleaning, inspection of safety controls, checking for proper combustion, and replacing filters. This prevents most emergency breakdowns and keeps your system running efficiently, which saves money on energy costs.

What's included in your furnace maintenance service?

Our maintenance service covers all the key components that keep your furnace running safely and efficiently. We clean and inspect the heat exchanger, check and adjust the burner, test safety controls, examine the venting system, and replace filters. For oil systems, we also check the fuel lines, clean the combustion chamber, and test the oil pump. Gas furnaces get inspection of the gas connections, flame sensor cleaning, and thermostat calibration. We test the system’s operation and provide you with a report of what we found, including recommendations for any issues that need attention before they cause problems.
