FURNACE REPLACEMENT & INSTALLATION
Properly Sized Furnace Installation
Replacing a furnace isn’t just about swapping one unit for another. The right furnace needs to match your home’s heating needs and work properly with the existing ductwork and airflow throughout the house.
Elite installs gas and propane furnaces throughout Southern New Hampshire. We’ll evaluate your existing system, the home, ductwork and heating needs before recommending equipment that makes sense—not simply replace the old furnace with the same size or sell you the biggest system available.
Proper sizing matters. An oversized furnace can heat the house too quickly, cycle on and off more often and create uneven temperatures. An undersized furnace may struggle to keep up during New Hampshire’s coldest weather. The goal is a system that delivers reliable, even heat and operates the way it was designed to.
A proper furnace installation takes more than replacing equipment. System setup, airflow, ductwork and proper installation all affect performance and comfort.
Repair or Replace?
Does Your Furnace Need to Be Replaced?
A problem with your furnace doesn't automatically mean you need a new system. Sometimes a repair is the smartest investment. Other times, continued repairs on an aging or unreliable furnace simply don't make sense.
Elite will look at the condition of your furnace, what's actually wrong with it, and what it will take to keep it running reliably. Then we'll walk you through the options so you can make an informed decision—not pressure you into replacing equipment that still has useful life.
Our approach is simple:
What would we recommend if this were our own family's home?
Age & Condition
How old is the furnace, and what condition is the equipment in overall?
Cost of the Repair
Does repairing the existing furnace make financial sense compared with replacement?
Repair History
Is this an isolated problem, or has the furnace required repeated repairs?
Efficiency & Preformance
Is the furnace heating the home effectively, maintaining comfortable temperatures and operating as efficiently as it should?
The Home's Heating Needs
If replacement makes sense, we'll look at what the home actually requires rather than simply matching the old equipment.
Replacement Heating System Efficiency
Your Furnace Is Only Part of the Heating System
Airflow & Ductwork
Restricted returns, undersized ducts, leaks and other airflow problems can make the furnace work harder and affect comfort, noise and system performance.
Hot & Cold Rooms
Uneven temperatures aren't always caused by the furnace itself. Airflow, duct layout, insulation and other conditions in the home can affect how efficiently heat is delivered from room to room.
Filtration & Indoor Airflow
The filter and return-air system need to provide proper airflow while protecting the equipment. A restrictive or neglected filter can reduce airflow and affect furnace performance.
Controls & System Operation
Thermostats, furnace controls and system setup influence how the equipment cycles and responds to changing heating demands. Proper operation helps the system deliver heat when and where it's needed.
Are You Ready for an Efficient Heating System?
We'll evaluate your system and identify opportunities to improve comfort and performance.
Our Process to Install
What to Expect When Replacing Your Furnace
Replacing your furnace is a big decision. We make the process straightforward with clear communication, expert guidance and professional installation from start to finish.
1. Evaluate the Existing System
We inspect your current furnace, ductwork, airflow and overall heating system to understand what’s working, what’s not and what your home actually needs.
2. Determine the Home's Needs
We consider your home’s size, layout, insulation and comfort goals to properly size and match the right system — no guesswork, no one-size-fits-all solutions.
3. Recommend the Right Equipment
We’ll walk you through the best options for your home, including high-efficiency models that deliver reliable heat, lower energy costs and long-term value.
4. Professional Installation & Setup
Our experienced technicians install your new furnace to manufacturer specifications, make sure everything is working properly, and test the system for safe, efficient operation.

Frequently Asked Questions about Gas Boilers
How long does it take to replace a furnace?
Most straightforward furnace replacements can be completed in a day. The exact time depends on the existing system, venting, gas piping, electrical work, ductwork and whether modifications are needed. Elite will evaluate the existing installation before the work begins so you'll know what to expect.
Should I replace my furnace and air conditioner at the same time?
Not necessarily. If both systems are older, replacing them together may make sense, particularly when they share components such as the furnace blower and indoor coil. If your air conditioner is newer and working properly, there may be no reason to replace it simply because the furnace needs replacement. We'll look at the complete system before making a recommendation.
How do I know what size furnace my home needs?
A replacement furnace shouldn't automatically be the same size as the furnace that's coming out. The home's heating needs, layout, insulation, ductwork and airflow all matter. Elite evaluates the home and existing system before recommending equipment so the new furnace is properly matched to the house.
Should a 20- or 25-year-old furnace automatically be replaced?
Age is an important consideration, but it isn't the only one. We also look at the furnace's condition, repair history, efficiency and how well it's heating the home. An older furnace that is operating safely and reliably may have useful life remaining, while repeated repairs or significant problems can make replacement the better option.
Are natural gas furnaces being phased out?
No. Natural gas furnaces are not being phased out in New Hampshire. New Hampshire law currently prevents local governments from prohibiting or restricting homeowners from installing safe, commercially available heating systems, including natural gas and propane systems.Federal efficiency standards for furnaces can change over time, but those are efficiency requirements—not a nationwide ban on gas furnaces. Current federal rules call for higher efficiency requirements for certain residential gas furnaces beginning in December 2028.
What should I consider when choosing a new furnace?
Efficiency matters, but it isn't the only consideration. Proper sizing, airflow, ductwork, equipment quality, controls and how the furnace works with the rest of the home's HVAC system all affect comfort and performance. The goal is to choose the right system for the home rather than simply the largest or highest-efficiency furnace available.
What happens to my old furnace when it is replaced?
This is another one I'd ask Elite Heating and Cooling before answering because we should describe exactly what Elite actually does with removal/disposal.
Should I replace my gas or propane furnace with a heat pump?
Not necessarily. Gas and propane furnaces remain viable heating options in New Hampshire, but today’s cold-climate heat pumps give homeowners another highly efficient option. Modern heat pumps can provide both heating and air conditioning from the same system while offering excellent energy efficiency and reducing the amount of energy needed to heat your home.Unlike older heat pumps, systems designed for cold climates can continue providing efficient, reliable heat even during very cold New Hampshire winter weather. Depending on your home, a heat pump may replace an existing heating system or work alongside your gas or propane system.Elite can evaluate your home, existing equipment and comfort needs to help determine which approach makes sense.
Are there rebates or incentives available for a new furnace in New Hampshire?
Yes. Depending on the efficiency rating of the gas or propane furnace you choose, you may be eligible for energy-efficiency rebates through the NHSaves program. We can help you identify qualifying equipment and provide the documentation you need to claim your savings.
Do you handle the disposal of my old furnace?
Absolutely! We offer a complete service from your old to your new systems. Our team handles the complete removal and safe, eco-friendly disposal of your old heating equipment as part of our standard installation service. You won't have to worry about leaving heavy equipment on your property.
