Gas Furnace Installation Process

Here's How Your Installation Actually Works

First, we assess your home’s heating requirements and existing ductwork. This isn’t a quick walk-through. We measure spaces, check insulation levels, and evaluate your current system’s performance issues. You get a clear explanation of what size furnace you actually need.

Next, we handle the removal of your old unit and prepare the installation area. We protect your floors and belongings during the work. The new furnace gets connected to your existing ductwork, gas line, and electrical systems according to manufacturer specifications and local codes.

Finally, we test everything before we leave. You see how the new controls work. We explain your warranty coverage and maintenance requirements. You get documentation for your records and contact information for future service needs.

What's Included in Your Installation

Your furnace installation includes proper sizing calculations based on your home’s square footage, insulation levels, and window efficiency. We don’t guess at what size unit you need. Many heating problems stem from incorrectly sized equipment that previous contractors installed without doing the math.

We handle all permit requirements and code compliance issues. Your installation meets Massachusetts building codes and manufacturer specifications. This protects your warranty coverage and ensures safe operation for your family.

You also get access to our Dempsey Comfort Club membership program. This gives you priority scheduling for future service calls and maintenance reminders to keep your new furnace running efficiently. Many Bristol County homeowners find this valuable for protecting their heating investment.

Most furnace installations take 4-8 hours depending on your home’s specific requirements. Straightforward replacements where we’re swapping out a similar unit usually finish faster. More complex jobs involving ductwork modifications, electrical upgrades, or venting changes take longer. We’ll give you a realistic timeframe upfront so you can plan accordingly. The goal is doing the job right, not rushing through it to get to the next appointment.
Furnace sizing depends on your home’s square footage, insulation quality, window efficiency, and ceiling height. We perform load calculations to determine the correct BTU output for your specific situation. Many homeowners assume bigger is better, but oversized furnaces cycle on and off frequently, wasting energy and creating uneven temperatures. Undersized units run constantly and struggle to maintain comfortable temperatures. Proper sizing ensures efficient operation and consistent comfort throughout your home.
Yes, replacing your furnace before it fails completely saves you money and stress. Emergency replacements during winter storms limit your options and often cost more. You have time to research different models, compare efficiency ratings, and schedule installation at your convenience. Warning signs include rising energy bills, frequent repairs, uneven heating, and units over 15-20 years old. Planning ahead means you choose the replacement timing instead of your furnace choosing it for you.
Furnace efficiency is measured by Annual Fuel Utilization Efficiency (AFUE) ratings. Higher AFUE percentages mean more of your fuel converts to heat instead of waste. A 90% AFUE furnace converts 90% of fuel to heat, while 10% goes up the chimney. Standard efficiency units run 80-85% AFUE, while high-efficiency models reach 90-98%. The higher upfront cost of efficient units typically pays back through lower monthly heating bills, especially in Massachusetts where heating seasons are long.
Yes, we handle all permit applications and coordinate required inspections with local authorities. This includes gas line connections, electrical work, and venting requirements. Each town in Bristol County has specific codes and inspection procedures. We know what inspectors look for and ensure your installation passes on the first visit. You don’t need to worry about navigating municipal requirements or scheduling inspection appointments. We manage that process from start to finish.
New furnaces typically include manufacturer warranties covering parts for 10-20 years, depending on the model you choose. Labor warranties vary by manufacturer and usually cover 1-2 years. We provide documentation for all warranty coverage and help you register your equipment with the manufacturer. Some warranties require annual maintenance to remain valid, which is why many customers join our Dempsey Comfort Club for regular service reminders and priority scheduling.
