Our HVAC Installation Process
A new HVAC system is a long-term investment in your home’s comfort and value. Here is how we approach it:
- In-Home Assessment — We evaluate your current system, ductwork condition, insulation levels, and home layout. We discuss your comfort priorities — even heating and cooling, humidity control, energy efficiency, or quiet operation.
- Load Calculation and System Design — We perform Manual J and Manual D calculations to determine the right equipment size and ductwork requirements for your home. This prevents the energy waste and comfort problems caused by improperly sized systems.
- Equipment Selection — We present options from top brands — Lennox, Carrier, Trane, and more — with side-by-side comparisons of efficiency ratings, features, warranties, and pricing. We also explain available rebates.
- Professional Installation — Our team handles everything — removing old equipment, installing the new system, upgrading ductwork if needed, running refrigerant lines, and making all electrical and gas connections per NC code requirements.
- Commissioning and Walkthrough — We test heating and cooling modes, measure airflow room by room, verify refrigerant charge, and calibrate your thermostat. Then we walk you through system operation, filter maintenance, and warranty details.

Frequently Asked Questions
How much does it cost to install a new HVAC system in Raleigh?
A complete HVAC installation in the Raleigh area typically costs between $5,000 and $12,500, depending on system type, efficiency rating, and home size. A straightforward equipment changeout (replacing units without modifying ductwork) runs $5,000 to $11,000. If new ductwork is needed, expect $7,000 to $16,000 and a longer installation timeline. High-efficiency systems with variable-speed technology can reach $12,000 to $15,000 but offer significantly lower operating costs. Federal tax credits of up to $2,000 for qualifying heat pumps can offset the upfront investment. Icy Hot provides free in-home estimates with detailed written quotes — call (919) 673-7667 to schedule yours.
How long does it take to install a new HVAC system?
A standard HVAC replacement — swapping existing equipment without ductwork changes — typically takes one full day (6 to 10 hours). More complex installations involving ductwork modifications, system relocation, or converting from one system type to another (such as switching from a furnace/AC combo to a heat pump) may take two to three days. Complete new installations with full ductwork in new construction or major renovations can take three to five days. Factors that affect timeline include attic or crawl space accessibility, the number of zones, and any electrical panel upgrades needed. Your Icy Hot installation team will provide a specific timeline during your pre-installation consultation.
What size HVAC system do I need for my home?
Proper sizing requires a Manual J load calculation — a detailed analysis of your home’s square footage, insulation levels, window types, ceiling heights, ductwork condition, and local climate data. As a rough guide, homes need approximately 25 BTUs per square foot, meaning a 2,000-square-foot Raleigh home typically needs a 4- to 5-ton system (48,000 to 60,000 BTUs). However, this varies significantly based on your home’s specific characteristics. An oversized system will short-cycle (turning on and off frequently), wasting energy and failing to dehumidify properly — a real problem in Raleigh’s humid climate. An undersized system will run constantly without reaching set temperatures. Never let a contractor quote a system size based solely on square footage.
Should I replace my furnace and AC at the same time?
In most cases, yes — replacing both components simultaneously is recommended when either unit reaches end of life. Modern HVAC systems are engineered to work together as matched systems, and pairing a new high-efficiency air conditioner with an old furnace (or vice versa) reduces overall efficiency and can void manufacturer warranties. Mismatched systems also put extra strain on the newer component. The cost savings of a combined installation are significant: you save on labor since the crew is already on-site, and many manufacturers offer package rebates for matched systems. The exception is if one component is relatively new (under 5 years old) and the other fails — in that case, replacing just the failed unit may make sense.
Do I need new ductwork with my HVAC installation?
Not always, but aging or poorly designed ductwork can significantly undermine a new system’s performance. The EPA estimates that typical duct systems lose 20% to 30% of conditioned air through leaks, holes, and poor connections. During installation, your contractor should inspect existing ductwork for leaks, crushed sections, inadequate insulation, and proper sizing for the new system’s airflow requirements. Many older Raleigh homes — especially those built before the 1990s — have ductwork that doesn’t meet current efficiency standards. If your ducts are in good condition with minimal leakage, they can be reused. But if testing reveals significant air loss, replacing or sealing ductwork will ensure you get the full benefit of your new equipment’s efficiency rating.
What permits are required for HVAC installation in Raleigh?
In Raleigh and Wake County, a mechanical permit is required for HVAC system installation or replacement. This applies to both residential and commercial projects. The permit ensures the installation meets North Carolina Mechanical Code requirements for safety, proper sizing, and energy efficiency. Your licensed HVAC contractor should pull the permit on your behalf — if a contractor suggests skipping the permit, that’s a major red flag. After installation, a city or county inspector will verify the work meets code. Electrical permits may also be required if the installation involves new circuits or panel upgrades. Icy Hot handles all permitting and inspection coordination as part of every installation project, so you don’t have to navigate the process yourself.
What HVAC brands do you recommend for Raleigh homeowners?
The best HVAC brand depends on your budget, efficiency goals, and comfort preferences. As a Lennox Authorized Dealer, Icy Hot has deep expertise with Lennox systems, which offer some of the highest SEER ratings in the industry (up to 28 SEER with their SL28XCV). We also install and service Carrier, Trane, Rheem, Goodman, York, Amana, Daikin, Bryant, Coleman, and Ruud systems. For budget-conscious homeowners, Goodman and Amana offer solid reliability at lower price points. For premium efficiency and ultra-quiet operation, Lennox and Carrier lead the market. We recommend choosing based on warranty coverage, efficiency ratings, and features rather than brand loyalty alone. Visit our brands page or call (919) 673-7667 for personalized recommendations.
