How long does furnace installation take in Dartmouth homes?

Most furnace installations take 6-8 hours for a simple replacement in homes with existing gas lines and proper electrical connections. If we need to upgrade your gas line, modify ductwork, or install new electrical connections, the job might extend to a full day or require a second visit. Older Dartmouth homes sometimes need additional work to bring everything up to current codes, which we’ll identify during our initial assessment. We always give you a realistic timeline upfront so you can plan accordingly.

What size furnace do I need for my Dartmouth home?

Furnace sizing depends on your home’s square footage, insulation levels, window types, and layout—not just the size of your old unit. Many homes in the Dartmouth area are overheated because previous contractors installed oversized equipment. We perform detailed load calculations to determine exactly what capacity you need for efficient, comfortable heating. An oversized furnace cycles on and off too frequently, wasting energy and creating uneven temperatures. The right-size furnace runs longer cycles, heating more evenly while using less fuel.

Should I choose a gas or oil furnace for my home?

If natural gas is available in your Dartmouth neighborhood, gas furnaces typically offer lower operating costs and cleaner burning than oil systems. Gas furnaces also require less maintenance and don’t need fuel deliveries or tank monitoring. However, if you’re in an area without gas service, a high-efficiency oil furnace can still provide excellent heating. We’ll evaluate your specific location, existing fuel infrastructure, and long-term cost considerations to recommend the best option for your situation and budget.

How much can I save on heating bills with a new furnace?

Homeowners typically see 20-40% reductions in heating costs when replacing furnaces that are 15+ years old with new high-efficiency models. Your actual savings depend on your current system’s efficiency, your home’s insulation, and your heating habits. Older furnaces often operate at 60-80% efficiency, while new models attain 90-95% efficiency ratings. In Bristol County’s climate, where heating season runs from October through April, these efficiency improvements translate to significant dollar savings over the system’s 15-20 year lifespan.

Do you handle permits and inspections for furnace installation?

Yes, we obtain all required permits and coordinate inspections with local authorities in Dartmouth and throughout Bristol County. This includes gas permits, electrical permits if needed, and any mechanical permits required by your municipality. We schedule inspections at appropriate stages of the installation and confirm everything passes before considering the job complete. Proper permitting protects you legally and assures your installation meets all safety codes. We handle all the paperwork and inspector coordination so you don’t have to navigate the permit process yourself.

What maintenance does my new furnace need after installation?

Your new furnace needs annual professional maintenance and regular filter changes to maintain efficiency and warranty coverage. We recommend scheduling maintenance each fall before heating season begins. The service includes cleaning, safety checks, and minor adjustments that keep your system running smoothly. You should change or clean filters every 1-3 months depending on your home’s dust levels and filter type. Many of our Dartmouth customers join our Dempsey Comfort Club for automatic maintenance scheduling and priority service. Proper maintenance extends your furnace’s lifespan and prevents most emergency breakdowns.
