New Furnace Installation Process

Straightforward Installation, No Surprises

Your furnace installation starts with a thorough assessment of your home’s heating needs. Our team calculates the right size system based on your square footage, insulation, and local climate demands. Getting this sizing right is critical because an oversized or undersized furnace will never perform efficiently.

Once we’ve determined the proper system specifications, we handle all the removal of your old equipment and prepare the installation area. The new gas furnace installation includes connecting all gas lines, electrical components, and ductwork connections according to Massachusetts building codes.

After installation, we test every component to ensure your system operates safely and efficiently. You’ll see exactly how your new furnace works, understand the basic maintenance requirements, and know who to call if you ever have questions. The entire process typically takes one day for standard installations.

Most standard furnace installations in Walpole homes take 6-8 hours to complete in a single day. The timeline depends on factors like whether you’re replacing an existing system or installing in a new location, if any ductwork modifications are needed, and the complexity of gas line connections. More complex installations involving significant ductwork changes or electrical upgrades might extend into a second day. Our installation team will give you a clear timeline estimate during the initial assessment so you know exactly what to expect.
Furnace sizing depends on your home’s square footage, insulation levels, ceiling height, window efficiency, and local climate factors specific to Norfolk County. A professional load calculation determines the exact BTU requirements for your space. Many homeowners assume bigger is better, but an oversized furnace actually reduces efficiency and comfort by short-cycling. An undersized system will struggle to maintain temperature during cold snaps. Our installation team performs this calculation during the assessment to ensure you get a system that heats your home efficiently without wasting energy.
Yes, furnace installation in Walpole requires permits from the local building department. This includes both a building permit for the installation work and a gas permit for any gas line connections or modifications. We handle all permit applications and inspections as part of our installation service. The permits ensure your installation meets Massachusetts building codes and safety requirements. Attempting to skip permits can create problems with insurance claims, home sales, and safety inspections. Working with licensed contractors ensures all permit requirements are properly handled.
Furnace installation costs vary based on system efficiency ratings, brand selection, installation complexity, and any necessary modifications to existing ductwork or gas lines. High-efficiency systems cost more upfront but provide significant long-term savings on monthly heating bills. The total investment includes the furnace unit, installation labor, permits, and disposal of old equipment. Many homeowners find that utility rebates and energy savings help offset the initial investment. A detailed estimate during the home assessment provides exact costs based on your specific installation requirements and system preferences.
Standard efficiency furnaces operate at 80-85% efficiency, meaning 15-20% of fuel energy is lost through venting. High-efficiency furnaces achieve 90-98% efficiency by capturing and using heat that would otherwise be vented outside. High-efficiency units require different venting systems and typically cost more initially, but they significantly reduce monthly heating bills. In Norfolk County’s climate, the energy savings often justify the higher upfront cost within 5-7 years. High-efficiency systems also tend to operate more quietly and provide more consistent temperatures throughout your home.
Replace your furnace if it’s over 15 years old and requiring frequent repairs, if repair costs exceed 50% of a new system’s cost, or if your energy bills have increased significantly despite normal usage. Other replacement indicators include uneven heating throughout your home, excessive dust or dry air, yellow pilot light flames, or rust and corrosion on the unit. If your furnace struggles to maintain comfortable temperatures during moderate weather, it likely won’t handle severe winter conditions reliably. A professional assessment can determine whether repair or replacement makes more financial sense for your specific situation.
