How long does a furnace installation typically take in Duxbury?

Straightforward replacements where the new furnace connects to existing systems usually take less time, while installations requiring new venting, electrical work, or ductwork modifications may take longer. Our installation team will give you a realistic timeframe during your consultation so you can plan accordingly. We work efficiently while maintaining thorough attention to safety and quality standards.

What size furnace do I need for my Duxbury home?

Furnace sizing depends on your home’s square footage, insulation levels, ceiling height, window efficiency, and Massachusetts climate requirements. A furnace that’s too small won’t keep you comfortable during cold snaps, while an oversized unit cycles on and off frequently, wasting energy and wearing out faster. Professional sizing involves calculating your home’s heat loss and matching it to the right BTU output. Our technicians perform detailed load calculations to determine the optimal size for your specific home, promoting efficient operation and consistent comfort throughout your house.

Do I need permits for furnace installation in Duxbury?

Yes, furnace installations in Duxbury typically require permits to make sure the work meets local building codes and safety standards. These permits cover gas connections, electrical work, and venting requirements. Professional contractors handle permit applications and the scheduling of required inspections as part of their installation service. Attempting to install a furnace without proper permits can create safety hazards, insurance issues, and problems when selling your home. Working with licensed contractors verifies all permit requirements are met and your installation passes inspection the first time.

How do I know if I need a new furnace or just repairs?

Consider furnace replacement if your system is over 15 years old, requires frequent repairs, struggles to heat your home evenly, or causes significant increases in your energy bills. Other signs include strange noises, visible rust or corrosion, yellow pilot light flames, or poor indoor air quality. If repair costs exceed half the value of a new furnace, replacement usually makes more financial sense. A professional assessment can help you weigh repair costs against replacement benefits, considering your furnace’s age, condition, and efficiency compared to newer models available today.

What's the difference between different furnace efficiency ratings?

Furnace efficiency is measured by Annual Fuel Utilization Efficiency (AFUE), which shows how much of your fuel converts to heat versus what’s lost through venting. Standard efficiency furnaces operate at 80% AFUE, meaning 20% of fuel is wasted. High-efficiency models reach 90-98% AFUE, converting more fuel to usable heat. While high-efficiency furnaces cost more upfront, they significantly reduce heating bills over time. In Massachusetts winters, the energy savings can be substantial. Your contractor can calculate potential savings based on your home’s heating needs and current energy costs to help determine the best efficiency level for your situation.

What maintenance does my new furnace need after installation?

New furnaces need regular filter changes every 1–3 months, depending on usage and filter type, annual professional maintenance, and basic upkeep like keeping vents clear and monitoring system performance. Annual maintenance includes cleaning components, checking gas connections, testing safety systems, and providing optimal efficiency. Our Comfort Club membership program provides scheduled maintenance, priority service, and member discounts. Proper maintenance extends your furnace’s lifespan, maintains warranty coverage, prevents unexpected breakdowns, and keeps your system running efficiently. Most manufacturers require annual professional maintenance to maintain warranty protection on your new investment.
