Lower Bills, Higher Comfort, Zero Worries

Your old furnace is costing you money every month it runs. Those rising energy bills aren’t just inflation – they’re your heating system telling you it’s time for an upgrade.

A new furnace installation cuts your heating costs significantly. Modern high-efficiency units use 20-30% less fuel than systems from even ten years ago. That’s real money back in your pocket every winter.

But the bigger win is reliability. No more wondering if your heat will kick on during a February cold snap. No more emergency repair calls when temperatures drop. Just consistent, comfortable warmth throughout your home, exactly when you need it most.

New Furnace Installation Process

Straightforward Installation, No Surprises

We start with a proper assessment of your home’s heating needs. This isn’t a sales pitch – it’s an engineering evaluation. We measure your space, check your ductwork, and calculate the exact capacity you need. Getting the size right matters more than most people realize.

Next, we handle all the permits and paperwork. Massachusetts has specific requirements for gas furnace installations, and we make sure everything meets code before we start. You don’t have to worry about inspections or compliance issues.

Installation day is typically completed in one day for most homes. We protect your floors, remove your old unit safely, and install your new furnace with minimal disruption to your routine. Before we leave, we test everything thoroughly and walk you through your new system’s operation.

Complete Furnace Installation Service

Everything Included, Nothing Extra

Your furnace installation includes proper sizing calculations, permit acquisition, safe removal of your old unit, and complete installation of your new system. We connect all gas lines, electrical connections, and ductwork modifications needed for optimal performance.

We also include system commissioning – that’s the thorough testing and calibration that ensures your new furnace operates at peak efficiency from day one. Many installers skip this step, but it’s crucial for getting the performance and savings you’re paying for.

After installation, you’re automatically eligible for our Dempsey Comfort Club membership. This gives you priority scheduling for any future service needs and helps maintain your system’s warranty requirements. It’s our way of making sure your investment stays protected long after we finish the installation.

Most furnace installations in Weweantic homes are completed in one day, typically 6-8 hours depending on your specific setup. If we need to modify ductwork or run new gas lines, it might extend to a second day. We’ll give you an accurate timeline during our initial assessment. Factors that can affect timing include the accessibility of your current furnace, any necessary electrical upgrades, and permit inspection scheduling. We always plan installations to minimize disruption to your daily routine and ensure you have heat when you need it most.
Furnace sizing depends on your home’s square footage, insulation levels, window efficiency, and local climate conditions. A properly sized unit for a typical Weweantic home ranges from 60,000 to 120,000 BTUs, but this varies significantly. Oversized furnaces cycle on and off too frequently, wasting energy and creating uneven heating. Undersized units run constantly and struggle to maintain comfort. We perform detailed heat load calculations during our assessment to determine the exact capacity your home requires. This engineering approach ensures optimal efficiency and comfort rather than guessing based on your old unit’s size.
Yes, we handle all permit applications and inspections required for furnace installation in Plymouth County. Massachusetts requires permits for gas furnace installations, and local codes specify installation requirements for safety and efficiency. We’re familiar with Weweantic’s specific requirements and maintain current relationships with local inspectors. This includes gas line connections, electrical work, and venting modifications. We schedule all required inspections and ensure your installation passes on the first visit. You don’t need to navigate the permit process yourself – we handle the paperwork and coordinate with local authorities as part of our installation service.
Modern high-efficiency furnaces typically reduce heating costs by 20-30% compared to units that are 10-15 years old. For an average Weweantic home spending $1,500 annually on heating, that translates to $300-450 in yearly savings. The exact savings depend on your current furnace’s efficiency rating, your home’s insulation, and your heating habits. Newer furnaces with AFUE ratings of 90% or higher extract much more heat from the same amount of fuel. We can calculate estimated savings for your specific situation during our assessment by comparing your current system’s efficiency to modern options.
All our furnace installations include manufacturer warranty coverage, typically 10-20 years on parts depending on the brand and model you choose. For service needs, Dempsey Comfort Club members receive priority scheduling and discounted rates on any maintenance or repairs. We maintain detailed records of every installation, so our technicians know exactly what equipment you have and when it was installed. Most service calls in the first few years involve minor adjustments or maintenance rather than major repairs. We’re available for emergency service calls when you need heat restored quickly, and our familiarity with your system helps us diagnose issues faster than companies unfamiliar with the installation.
Yes, we perform furnace installations year-round, including during Massachusetts winters. Winter installations require extra planning to ensure you’re never without heat for extended periods. We typically schedule these installations on milder days when possible and work efficiently to minimize the time your home is without heating. In some cases, we can install temporary heating solutions while completing the work. Emergency replacements during winter are common when old furnaces fail unexpectedly. We stock popular furnace models specifically for these situations and can often complete emergency installations within 24-48 hours of your call, depending on equipment availability and permitting requirements.
