New Furnace Installation Process

Straightforward Installation, Professional Results

The process starts with a thorough assessment of your home’s heating needs. This isn’t about selling you the biggest system—it’s about determining the right size furnace for your square footage, insulation, and layout. Proper sizing prevents short cycling, reduces energy waste, and ensures even heating.

Installation day begins with protecting your home. Drop cloths, shoe covers, and careful handling of your belongings. The old system comes out, new gas lines and electrical connections are verified for safety, and your new furnace goes in with precise attention to manufacturer specifications.

Before leaving, everything gets tested. Gas pressure, electrical connections, airflow, and safety systems all get checked. You’ll receive a walkthrough of your new system’s operation and maintenance requirements. The goal is simple: you should feel completely confident about your new heating system from day one.

Complete Installation, Not Just Equipment Delivery

Furnace installation includes everything needed for safe, efficient operation. Gas line inspection and modification if needed. Electrical connections that meet Massachusetts code requirements. Ductwork assessment and sealing to prevent heat loss. Proper venting to make sure safe exhaust removal.

Many Attleboro homes have unique challenges—older ductwork, tight basement spaces, or existing systems that weren’t installed optimally. Our familiarity with local home construction styles enables us to navigate these challenges without compromising safety or efficiency.

Every installation includes manufacturer warranty registration, system startup, and performance verification. You’re not just getting a new furnace—you’re getting a complete heating solution designed to work reliably in your specific home for years to come.

Most furnace installations take 6-8 hours for a clear replacement where existing gas lines and electrical connections are adequate. If modifications are needed—like upgrading gas lines, electrical service, or significant ductwork changes—installation may extend to a full day or require a second visit. The timeline depends on your home’s specific setup, but you’ll know the expected schedule before work begins. Emergency replacements often get priority scheduling to restore your heat quickly.
Furnace sizing depends on your home’s square footage, insulation levels, window types, ceiling height, and local climate conditions. A Manual J load calculation determines the exact BTU requirements for your specific home. Oversized furnaces waste energy and create uneven heating, while undersized units struggle to maintain comfort during cold snaps. Most Attleboro homes need between 60,000-120,000 BTU systems, but proper sizing requires an on-site assessment rather than guessing based on your old furnace size.
Gas furnaces are typically more cost-effective for Massachusetts heating due to lower fuel costs and better performance in extreme cold. Natural gas burns hotter than electric heat pumps can produce, verifying reliable warmth even when temperatures drop below zero. Electric systems work well in milder climates but struggle with efficiency during harsh New England winters. If natural gas is available in your Attleboro neighborhood, it’s usually the better choice for both operating costs and reliable heating performance.
Yes, furnace installation requires permits in Attleboro to assure safety compliance with Massachusetts building codes. Permits cover gas line connections, electrical work, and venting systems. Professional contractors handle permit applications and schedule required inspections as part of the installation process. Attempting installation without proper permits can create safety hazards, void manufacturer warranties, and cause problems when selling your home. The permit process typically adds 1-2 days to the project timeline but confirms everything meets local safety standards.
Energy savings depend on your current furnace age and efficiency rating. Replacing a 15-20 year old furnace with a modern high-efficiency unit typically reduces heating costs by 20-30%. If your old system is even older or poorly maintained, savings can reach 40% or more. A new 90%+ efficiency furnace converts nearly all fuel into usable heat, compared to older systems that waste significant energy through venting. Actual savings vary based on home size, insulation, and heating habits, but most homeowners see noticeable bill reductions within the first heating season.
New furnaces need annual professional maintenance to maintain efficiency and warranty coverage. This includes filter changes every 1-3 months depending on usage and annual cleaning of burners and heat exchangers, and inspection of safety systems. Regular maintenance prevents small problems from becoming expensive repairs and keeps your system running at peak efficiency. Many manufacturers require proof of annual maintenance to honor warranty claims. Our Dempsey Comfort Club provides scheduled maintenance reminders and priority service to keep your investment protected.
