New Furnace Installation Process

Here's How We Install Your Furnace

First, we’ll assess your home’s heating needs and existing ductwork to determine the right furnace size and type. This isn’t guesswork – proper sizing is critical for efficiency and comfort. We’ll also check your electrical and gas connections to ensure everything meets current Massachusetts building codes.

Next comes the actual installation. We’ll remove your old furnace safely, install the new unit, and connect all gas lines, electrical connections, and ductwork. Every connection gets tested for safety and proper operation before we consider the job complete.

Finally, we’ll walk you through your new system’s operation and maintenance requirements. You’ll know how to change filters, what sounds are normal, and when to call us. We’ll also discuss Dempsey Comfort Club membership to keep your furnace running efficiently for years to come.

Many Rockland homeowners are surprised by how much more evenly their homes heat after a professional installation. That’s because we take time to properly connect and seal all ductwork connections, not just hook up the furnace itself. The details matter when it comes to home comfort and energy efficiency.

Most furnace installations take 4-8 hours depending on your home’s setup and whether we’re replacing an existing unit or installing in a new location. If your current furnace is in a tight basement or we need to run new gas lines, it might take longer. We’ll give you a realistic timeframe upfront so you can plan accordingly. Emergency replacements during winter often get priority scheduling, and we’ll work efficiently to restore heat to your home as quickly as possible while still doing the job right.
Furnace sizing depends on your home’s square footage, insulation levels, window types, and how well-sealed your home is. Many older Plymouth County homes need different calculations than newer construction. We perform a heat load calculation that considers your specific home’s characteristics rather than just using square footage rules of thumb. An oversized furnace will cycle on and off too frequently, wasting energy and wearing out faster. An undersized unit won’t keep you comfortable during cold snaps. Getting the size right is critical for both comfort and efficiency.
Yes, we can work with existing ductwork in most cases, though we’ll inspect it first to make sure it’s in good condition. Many Rockland homes have ductwork that’s perfectly functional but just needs some sealing or minor repairs. If your ducts are damaged, improperly sized, or poorly insulated, we’ll let you know what needs attention. Sometimes we can upgrade sections of ductwork during the furnace installation to improve your overall system performance. We’ll be upfront about what work is necessary versus what would just be nice to have.
Absolutely. We’re licensed to handle all gas line work required for furnace installations, including running new lines if needed. Gas connections must be done properly for safety reasons – this isn’t a DIY job. We’ll inspect your existing gas line to make sure it’s the right size for your new furnace and test all connections for leaks before firing up your system. All gas work gets inspected to ensure it meets Massachusetts codes. If you smell gas at any point, turn off your gas at the meter and call us immediately.
Your new furnace comes with manufacturer warranty coverage, and our installation work is guaranteed as well. If something isn’t working right, call us first – many issues are simple fixes or settings adjustments. We’ll troubleshoot the problem and determine whether it’s a warranty issue or something else. Dempsey Comfort Club members get priority service scheduling and discounts on any repairs that aren’t covered under warranty. We stand behind our installation work and want your furnace running properly, so don’t hesitate to reach out if you notice any issues.
If your furnace is over 15 years old, needs frequent repairs, or your energy bills keep climbing, it’s worth considering replacement before you’re stuck without heat in January. Emergency replacements cost more and limit your options since you need heat restored quickly. Planning ahead lets you research different furnace options, take advantage of rebates or financing, and schedule installation when it’s convenient. We can assess your current furnace’s condition and give you an honest opinion about whether it’s worth repairing or time to replace.
