Thinking about HVAC or AC replacement in Harrington Grove, NC? You’re likely looking at a cost between $5,000 and $11,500 for a full system replacement. This range depends on factors like the size of your home, the efficiency of the unit you choose, the complexity of the installation, and whether ductwork modifications are needed.

Material Prices
Here’s a general overview of pricing based on different HVAC system types. Note that “material prices” refers to the cost of the unit itself and associated components, not installation labor.
| HVAC System Type | Average Material Cost (Installed) | Notes |
|---|---|---|
| Standard Efficiency AC & Furnace | $5,000 – $7,000 | Meets minimum SEER2 requirements. Good for smaller homes or budget-conscious homeowners. |
| Mid-Efficiency AC & Furnace or Heat Pump | $7,000 – $9,500 | Offers better energy savings. Heat pumps are increasingly popular in NC. |
| High-Efficiency AC & Furnace or Heat Pump (Variable Speed) | $9,500 – $11,500+ | Maximum energy savings and comfort. Variable-speed compressors excel at dehumidification, crucial for NC summers. |
| Dual-Fuel System (Heat Pump & Gas Furnace) | $8,000 – $12,000+ | Excellent for NC’s moderate winters and hot summers. Heat pump handles milder temperatures; gas furnace provides efficient heating in colder weather. |
Local Factors
Several local factors impact the cost of HVAC and AC replacement in Harrington Grove:
* **Permits:** Wake County requires permits for HVAC replacements. The cost varies but typically adds a few hundred dollars to the overall project. Your contractor should handle the permit process.
* **Installation Labor Rates:** Labor rates in the Raleigh/Cary/Apex area are generally between $75 and $150 per hour, depending on the contractor’s experience and the complexity of the job. Be sure to get multiple quotes.
* **Ductwork:** Older homes in Harrington Grove may have leaky or poorly designed ductwork. Duct sealing or replacement can add significantly to the cost but is essential for system efficiency. Expect to pay between $500-$2,000 for ductwork modifications.
* **NCLIC Licensing:** Always ensure your contractor is licensed by the North Carolina State Board of Examiners (NCLIC). This ensures they meet minimum standards for safety and code compliance. Unlicensed contractors may offer lower prices, but it’s a risky proposition.
Weather Impact
Harrington Grove’s humid subtropical climate significantly affects HVAC system performance. Here’s what to consider:
* **Humidity:** The high humidity during the summer months puts a strain on AC systems. Variable-speed compressors are highly recommended as they’re much better at removing moisture from the air than single-stage units, leading to improved comfort and energy savings.
* **Pollen:** North Carolina is notorious for its pollen seasons, especially in the spring. Invest in high-quality air filtration (HEPA filters are ideal) and schedule regular HVAC maintenance to clean the coils and prevent pollen buildup, which can reduce efficiency and cause damage.
* **SEER2 Standards:** As of 2023, new SEER2 efficiency standards are in effect. Ensure your new system meets these standards for optimal energy savings.
* **Heat Pump Efficiency:** The relatively mild winters in Harrington Grove make heat pumps a viable and efficient heating option. Consider a dual-fuel system (heat pump with a gas furnace backup) for the best of both worlds.
