Furnace Installation in Raleigh, NC
Properly sized furnaces for even warmth in every room
Furnace Installation Services in the Triangle
Your old furnace has served you well, but furnaces do not last forever. If yours is 15 or more years old, costing more to repair each season, or leaving rooms cold while others overheat, a new furnace can transform your home comfort and slash your heating bills.
Proper installation is just as important as the furnace you choose. Icy Hot’s NATE-certified technicians size your new system with a load calculation, ensure proper airflow and venting, and test everything before they leave — so your new furnace runs safely and efficiently from day one.

Our Furnace Installation Process
A new furnace should keep your family warm for 15 to 20 years. Here is how we make sure you get the right one:
- In-Home Assessment — We evaluate your current furnace, ductwork, gas or electrical supply, and venting system. We discuss your heating priorities — even temperatures, quiet operation, energy efficiency, or all of the above.
- Sizing and Selection — We calculate the correct furnace size for your home using industry-standard load calculations. Then we present options ranging from 80% AFUE standard efficiency to 98%+ high-efficiency condensing models, with clear cost and savings comparisons.
- Old System Removal — Our team safely disconnects and removes your existing furnace, including proper disposal. We inspect the ductwork, gas lines, and flue connections to identify any issues before installing the new unit.
- New Furnace Installation — We install the new furnace, connect gas or electrical supply, seal all duct connections, and install the proper venting — whether standard B-vent or PVC venting for high-efficiency condensing models. Every installation meets NC mechanical code.
- Combustion Testing and Walkthrough — We perform combustion analysis to verify safe and efficient operation, check for gas leaks, test all safety controls, and walk you through thermostat operation, filter access, and recommended maintenance schedules.

Frequently Asked Questions
How much does a new furnace installation cost in Raleigh?
In the Raleigh-Durham area, a new furnace installation typically costs $3,500 to $8,000, with the average homeowner paying around $5,500-$6,500 for a mid-efficiency to high-efficiency gas furnace including full installation. Electric furnace installations run lower at $2,000 to $5,000. The total cost depends on the furnace brand and efficiency rating, the complexity of the installation (existing ductwork condition, gas line requirements, venting modifications), and the size of the unit needed for your home. Premium high-efficiency models (96-98% AFUE) with variable-speed blowers can push costs to $8,000-$12,000. Icy Hot Heating & Air Conditioning provides free in-home estimates — call (919) 673-7667 to schedule yours.
What is the difference between a single-stage and two-stage furnace?
A single-stage furnace operates at one speed — full blast — and cycles on and off to maintain temperature, which creates noticeable temperature swings. A two-stage furnace has a low setting (around 65% capacity) and a high setting (100% capacity), running on low most of the time and only switching to high during extremely cold weather. The result is more consistent temperatures, quieter operation, and 10-15% better energy efficiency. Two-stage furnaces cost $1,000-$2,500 more than single-stage models, but the energy savings typically offset that premium over 5-8 years. For Raleigh’s mild winters, a two-stage furnace is often ideal because it spends most of the season running efficiently on low.
How long does it take to install a new furnace?
A straightforward furnace replacement — where the new unit is the same type and similar size as the old one — typically takes 4-8 hours to complete in a single day. This includes removing the old furnace, installing the new unit, connecting gas and electrical lines, testing the system, and verifying proper airflow. More complex installations that require ductwork modifications, new gas line runs, or switching from one fuel type to another can take 1-2 days. The installation timeline also depends on the furnace’s location (attics and crawl spaces require more time) and whether any code-required upgrades are needed. Icy Hot schedules installations to minimize disruption to your household.
Do I need a permit to install a new furnace in North Carolina?
Yes, North Carolina requires a mechanical permit for furnace installations and replacements. In Wake County and the City of Raleigh, your HVAC contractor must pull the permit before beginning work, and the installation must pass a final inspection by a local building inspector. The permit ensures the installation meets NC Mechanical Code requirements for gas line connections, electrical wiring, venting, combustion air, and clearances from combustible materials. Permits typically cost $75-$200 depending on the jurisdiction. A reputable HVAC company like Icy Hot handles all permitting and inspection scheduling as part of the installation process — never hire a contractor who suggests skipping the permit.
What brand of furnace is most reliable?
The most reliable furnace brands consistently rated by industry professionals and consumer reports include Lennox, Carrier, Trane, Rheem, and Bryant. Lennox offers some of the highest-efficiency models on the market (up to 98.7% AFUE), while Carrier and Trane are known for robust build quality and extensive dealer networks. For value-oriented options, Goodman and Amana offer solid warranties at lower price points. The “best” brand ultimately depends on your budget, efficiency goals, and the quality of the installation — a mid-range furnace installed correctly will outperform a premium furnace installed poorly. As an authorized Lennox dealer and multi-brand service partner, Icy Hot can help you compare options for your specific needs.
Are there tax credits or rebates for a new furnace in 2026?
Yes, the federal Inflation Reduction Act (IRA) offers tax credits of up to $600 for qualifying high-efficiency gas furnaces meeting the Energy Star Most Efficient criteria (typically 97%+ AFUE). Additionally, the IRA’s HOMES rebate program, administered through North Carolina’s state energy office, may offer $2,000-$8,000 in rebates for whole-home energy efficiency upgrades that include furnace replacement. Duke Energy also periodically offers rebates for high-efficiency HVAC installations. To qualify for federal tax credits, keep your manufacturer’s certificate, contractor invoice, and proof of AFUE rating. Icy Hot Heating & Air Conditioning can help identify which incentives apply to your specific installation.
Should I replace my furnace and AC at the same time?
Replacing both systems simultaneously is often the best approach, and here’s why: your furnace and air conditioner share the blower motor and ductwork, so matching their capacities ensures optimal efficiency and performance. A mismatched system — such as a new high-efficiency furnace paired with an aging AC — can reduce overall efficiency and may void certain manufacturer warranties. Bundling both replacements also saves on labor costs since the technician is already on site, and many manufacturers offer enhanced warranties when you install a matched system. In the Triangle area, where you rely on both heating and cooling year-round, a coordinated replacement maximizes comfort and long-term savings.
