Furnace Installation Process

How Your Installation Actually Works

First, we assess your home’s heating needs and current setup. This includes measuring your space, checking your existing ductwork, and determining the right size furnace for efficient operation. No guessing or shortcuts.

Next, we handle permits and schedule your installation around your availability. Our team arrives on time, protects your floors and belongings, and removes your old system safely. We install your new gas furnace according to manufacturer specifications and Massachusetts codes.

Finally, we test everything thoroughly before we leave. You’ll understand how your new system operates, and we’ll schedule any necessary inspections. Your heating system gets added to our service database so we can maintain it properly going forward.

What Your Installation Includes

Your furnace installation covers everything needed for safe, efficient operation. We handle permit applications, old equipment removal, and proper disposal. Your new system gets connected to existing ductwork or we’ll modify connections as needed.

Every installation includes thorough testing of all safety systems, thermostat setup, and system commissioning. We verify proper airflow, check gas connections for leaks, and ensure your furnace operates at peak efficiency before leaving your home.

You receive manufacturer warranty information, operating instructions, and access to our Dempsey Comfort Club for ongoing maintenance. We also schedule any required municipal inspections and handle any follow-up requirements to keep your installation compliant.

Most furnace installations take 4-8 hours depending on your home’s setup and whether modifications are needed. Straightforward replacements where we’re swapping similar equipment usually finish faster. If we need to modify ductwork, run new gas lines, or relocate equipment, it takes longer. We’ll give you a realistic timeframe during your estimate so you can plan accordingly. Emergency replacements often get priority scheduling, especially during cold weather when you need heat restored quickly.
Furnace sizing depends on your home’s square footage, insulation quality, window efficiency, and ceiling height. We perform load calculations to determine exact heating requirements rather than guessing based on your old unit. An oversized furnace cycles on and off too frequently, wasting energy and wearing out faster. An undersized unit runs constantly and never keeps you comfortable. Proper sizing ensures efficient operation, even heating, and longer equipment life. This calculation is included in every installation estimate.
Yes, we handle permit applications and coordinate required inspections in Weymouth and throughout Norfolk County. Massachusetts requires permits for most furnace installations, and local codes specify safety requirements we must follow. We submit applications, schedule inspections, and address any issues that come up during the approval process. This ensures your installation meets all local requirements and protects you from potential problems when you sell your home or file insurance claims later.
Most older homes can accommodate high-efficiency furnaces, though some modifications might be needed. High-efficiency units produce condensation that requires drainage, and they often need different venting than older furnaces. We evaluate your existing setup and explain what changes are necessary. Sometimes this involves adding condensate drains, updating electrical connections, or modifying venting systems. The energy savings usually justify these upgrades, and we’ll show you projected costs and savings during your consultation.
Your new furnace comes with manufacturer warranty coverage, and our installation work is guaranteed. If problems develop, we diagnose whether it’s a manufacturing defect or installation issue and handle warranty claims accordingly. Our service team knows your system because we installed it, so troubleshooting is faster and more accurate. Dempsey Comfort Club members get priority service scheduling and discounted repairs. We maintain detailed records of your installation and service history to provide better ongoing support.
Replacing your furnace before complete failure gives you more options and better timing. You can research equipment options, compare contractors, and schedule installation when convenient rather than during an emergency. Older furnaces become less efficient and more expensive to repair as parts become harder to find. If your furnace is over 15 years old, requires frequent repairs, or your energy bills keep increasing, replacement often makes financial sense. We can evaluate your current system and help you decide whether repair or replacement is the better investment.
