What's Included in Every Installation

Every furnace installation includes proper sizing calculations for your specific home. We don’t guess at BTU requirements or assume your old furnace was the right size. Your new system gets sized correctly from day one.

All necessary permits and inspections are handled by our team. We coordinate with local authorities so you don’t have to navigate that process. Your installation meets all current codes and safety requirements.

You also get access to our Dempsey Comfort Club for ongoing maintenance and priority service. Regular maintenance keeps your warranty valid and your system running efficiently for years to come.

Most furnace installations in Westwood homes complete within 6-8 hours, typically finishing in one day. The timeline depends on your specific situation – replacing a furnace in the same location with existing gas lines and ductwork goes faster than installations requiring new connections or ductwork modifications. We’ll give you a realistic timeframe during our initial assessment so you can plan accordingly. Our goal is getting your heat back on quickly while doing the job right.
Furnace sizing depends on your home’s square footage, insulation levels, window types, and ceiling heights – not just a simple calculation. Many Westwood homes built in the 60s and 70s have different heating requirements than newer construction. We perform a proper heat load calculation that considers your specific home’s characteristics. Oversized furnaces waste energy and don’t heat evenly, while undersized units struggle to keep up during cold snaps. Getting the size right matters for both comfort and efficiency.
Yes, we handle all permit applications and scheduling inspections with Westwood building authorities. Furnace installations require permits to ensure safety and code compliance, and we manage that entire process for you. We know local requirements and have established relationships with inspectors, which helps avoid delays. You don’t need to visit town hall or coordinate inspection schedules – we take care of those details so your installation stays on track.
High-efficiency furnaces (90%+ AFUE rating) extract more heat from the same amount of gas, reducing your monthly energy costs. Standard efficiency units (80-85% AFUE) cost less upfront but use more fuel over time. In Massachusetts’ climate, the energy savings from high-efficiency models often offset the higher initial cost within a few years. High-efficiency furnaces also require different venting systems and may need condensate drains, which we factor into your installation planning.
If your furnace is over 15 years old and requiring frequent repairs, replacement usually makes more financial sense than continuing to fix an aging system. Other signs include uneven heating throughout your home, rising energy bills, and difficulty maintaining comfortable temperatures. We can assess your current system’s condition and give you honest guidance about repair versus replacement costs. Sometimes a well-maintained 12-year-old furnace just needs a specific repair, while a neglected 10-year-old unit might be ready for replacement.
New furnaces typically include manufacturer warranties covering parts for 10-20 years, depending on the model and brand. Heat exchangers often have longer warranty periods than other components. Our installation work carries a separate warranty covering labor and workmanship. We also provide warranty registration and can handle warranty claims if issues arise. Keeping up with regular maintenance through our Dempsey Comfort Club helps ensure warranty coverage remains valid throughout the warranty period.
