Furnace Installation Process

Here's How We Handle Everything

We start with a proper assessment of your home’s heating needs, not a quick sales pitch. Our technician measures your space, checks your existing ductwork, and calculates the right size furnace for your specific situation. Getting this wrong means you’ll either waste money on oversized equipment or struggle with an undersized system.

Installation day means our crew arrives on time with everything needed to complete the job. We remove your old furnace, install the new system, connect all gas and electrical lines, and test everything thoroughly. You’re not left wondering if something was missed.

Before we leave, we walk you through your new system’s operation and maintenance schedule. We also set you up in our service system so you’re covered if you need anything down the road. Your furnace comes with manufacturer warranties, and our work is guaranteed.

Professional Furnace Replacement

What's Included With Every Installation

Every new furnace installation includes proper sizing calculations, complete removal of your old system, and professional installation of your new equipment. We handle all gas line connections, electrical work, and ductwork modifications needed to get everything running correctly.

You get a full system test and walkthrough so you understand how to operate your new furnace efficiently. We also include initial filter replacement and show you how to maintain your system between service visits.

Our installations come with manufacturer warranties on equipment and our guarantee on workmanship. As a Norwell homeowner, you’re dealing with heating challenges specific to our area – older homes, varying insulation levels, and the reality of heating costs that can make or break your winter budget. We size and install systems that work with your home’s actual conditions, not just what looks good on paper.

Most furnace installations take 4-8 hours depending on your home’s setup and whether we need to modify existing ductwork or gas lines. Straightforward replacements where we’re swapping similar equipment usually finish in half a day. More complex installations involving ductwork changes, electrical upgrades, or challenging access can extend into a full day. We’ll give you a realistic timeline during our initial assessment so you can plan accordingly. The key is doing the job right rather than rushing through it, because proper installation directly affects how well your furnace performs and how long it lasts.
Furnace sizing depends on your home’s square footage, insulation levels, window types, ceiling height, and how well your ductwork distributes air. Many Norwell homes were built when energy efficiency wasn’t a priority, so older sizing calculations often don’t apply. We perform a proper heat load calculation that factors in your home’s specific characteristics rather than using rough estimates. An oversized furnace cycles on and off too frequently, wasting energy and wearing out faster. An undersized system runs constantly and never quite keeps up during cold snaps. Getting the size right means better comfort and lower operating costs.
Yes, replacing your furnace before complete failure gives you better options and timing control. When you’re not in emergency mode, you can research different models, compare efficiency ratings, and schedule installation when it’s convenient. Emergency replacements often mean limited equipment availability and higher costs because you need heat immediately. If your furnace is over 15 years old, needs frequent repairs, or your heating bills keep climbing, replacement usually makes more financial sense than continuing to patch an aging system. We can assess your current furnace’s condition and help you decide if replacement makes sense now or if you can safely wait.
Energy savings depend on your current furnace’s age and efficiency compared to the new system you choose. Replacing a 15-20 year old furnace with a modern high-efficiency unit typically reduces heating costs by 20-30%. If your current system is even older or poorly maintained, savings can be higher. Modern furnaces also provide more consistent temperatures, so you’re not constantly adjusting the thermostat trying to get comfortable. We can review your recent heating bills and estimate potential savings based on the efficiency ratings of different furnace options. The savings add up over time, often offsetting much of the installation cost over the furnace’s lifespan.
Yes, we handle all necessary permits and coordinate required inspections as part of our installation service. Norwell and Plymouth County have specific requirements for HVAC installations, especially involving gas connections and electrical work. We’re familiar with local codes and inspection processes, so you don’t have to navigate that yourself. Our technicians are properly licensed for the work we perform, and we make sure everything meets or exceeds local safety standards. After installation, we schedule any required inspections and address anything inspectors note. This is part of doing the job completely rather than leaving you to figure out compliance issues.
New furnaces need regular filter changes, annual professional maintenance, and basic upkeep to maintain efficiency and warranty coverage. We’ll show you how to check and replace filters, which typically need changing every 1-3 months depending on your home’s conditions. Annual maintenance includes cleaning, inspection, and adjustment of all system components to keep everything running efficiently. Our Dempsey Comfort Club members get priority scheduling for maintenance visits and reminders when service is due. Proper maintenance prevents most emergency breakdowns and keeps your furnace running efficiently throughout its lifespan. Neglecting maintenance voids most manufacturer warranties and leads to higher operating costs and premature system failure.
