Most furnace installations take between 4-8 hours depending on your home’s setup and the complexity of the job. Straightforward replacements in easily accessible areas typically finish faster, while installations requiring ductwork modifications or electrical upgrades take longer. We’ll give you a realistic timeframe after assessing your specific situation, and we always clean up completely before leaving. You’ll have heat the same day in most cases.
Furnace sizing depends on your home’s square footage, insulation levels, window types, and ceiling heights. A unit that’s too small won’t keep you warm during cold snaps, while an oversized furnace wastes energy and cycles on and off too frequently. We perform detailed load calculations to determine the right BTU output for efficient heating. Massachusetts homes often need higher capacity due to our climate, but proper sizing ensures you get consistent comfort without overpaying for energy.
Yes, furnace installations in Massachusetts require permits to ensure safety and code compliance. We handle all permit applications and inspections as part of our service, so you don’t need to navigate the municipal requirements yourself. Local codes are strict about gas connections, electrical work, and venting systems – all critical for safe operation. Having proper permits also protects your home insurance coverage and helps with resale value down the road.
Absolutely. Many Plymouth County homes have ductwork that needs modifications for optimal furnace performance. We’ll assess your existing ducts and recommend improvements that enhance efficiency and comfort. This might include sealing leaks, adding return air ducts, or resizing supply ducts for better airflow. Proper ductwork is crucial for getting the most from your new furnace, and we have the expertise to handle both the furnace installation and any ductwork improvements needed.
We stand behind our installation work and offer comprehensive support if issues arise. Most problems in the first year relate to manufacturer defects covered under warranty, which we’ll handle directly with the manufacturer. If installation-related issues occur, we’ll return promptly to address them at no additional cost. Our Dempsey Comfort Club members get priority service scheduling, and we maintain detailed records of every installation to quickly diagnose any concerns that develop.
Replacing your furnace before complete failure gives you more options and better timing. You can research different models, take advantage of rebates or seasonal promotions, and schedule installation at your convenience rather than during an emergency. Furnaces over 15 years old often have declining efficiency and increasing repair costs. If you’re noticing higher energy bills, uneven heating, or frequent repairs, replacement usually makes more financial sense than continuing to patch an aging system.
