New Furnace Installation Process

Here's Exactly What Happens

First, we assess your current system and calculate the proper size furnace for your home. Not bigger because it’s easier – the right size for efficiency and comfort. We’ll explain what we found and give you a clear estimate with no surprises.

Installation day starts with protecting your floors and workspace. We remove your old system, install the new furnace with proper connections and safety checks, then test everything thoroughly. The whole process typically takes 4-6 hours for a standard replacement.

Before we leave, we walk 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 clean up completely – you shouldn’t know we were there except for the new furnace running quietly in your basement.

Most furnace installations take 4-6 hours for a standard replacement where we’re swapping an old furnace for a new one in the same location. If we need to relocate the unit, upgrade gas lines, or modify ductwork, it might take a full day. Emergency replacements often get priority scheduling, and we can usually complete same-day installation when your heating fails. We’ll give you an accurate time estimate after assessing your specific situation and won’t leave you guessing about when you’ll have heat again.
Furnace size depends on your home’s square footage, insulation levels, window efficiency, and local climate conditions. Many contractors just look at your old furnace and install the same size, but that’s often wrong – older furnaces were frequently oversized. We perform proper load calculations to determine the right BTU capacity for your specific home. An oversized furnace cycles on and off too frequently, wasting energy and creating uneven temperatures. An undersized unit runs constantly and can’t keep up on the coldest days.
Yes, we install furnaces year-round, including during Massachusetts winters. In fact, winter is when most emergency furnace installations happen because that’s when old systems finally give up. We carry temporary heating equipment when needed and work efficiently to minimize the time your home is without heat. Cold weather doesn’t affect the installation quality, though we may need to take extra precautions with frozen pipes or accessing outdoor equipment. Emergency installations often get same-day service because we understand you can’t wait for heat when it’s 20 degrees outside.
Most furnace replacements in Rehoboth require permits, especially when changing fuel types or significantly upgrading the system. We handle permit applications and ensure all work meets local building codes and Massachusetts state requirements. The permit process typically adds a day or two to scheduling but protects you by ensuring proper inspections. Some simple like-for-like replacements might not require permits, but we’ll verify with local authorities. Skipping required permits can cause problems with insurance claims and home sales later, so we always check rather than assume.
Gas furnace installation connects to existing natural gas lines and requires proper venting through your chimney or direct vent system. Oil furnaces need fuel storage tanks and different venting requirements. Gas systems typically cost less to operate and require less maintenance, while oil systems work well in areas without natural gas service. Installation complexity depends on your existing setup – converting from oil to gas requires new gas line installation and tank removal. Both types need proper sizing, professional installation, and regular maintenance, but gas systems generally offer better efficiency and convenience for most Rehoboth homeowners.
Replace your furnace if it’s over 15-20 years old, needs frequent repairs, or your energy bills keep climbing despite normal usage. If repair costs exceed half the price of a new furnace, replacement makes more financial sense. Other replacement signs include uneven heating, excessive dust, yellow pilot light flames, or rust around the unit. Newer furnaces that just need minor repairs are usually worth fixing. We’ll give you honest advice about repair versus replacement based on your furnace’s condition, age, and repair history. Sometimes a $200 repair buys you several more years, other times replacement is the smarter investment.
