Material Prices
Here’s a general idea of material costs associated with different types of HVAC and AC systems. Remember these are estimates and can vary:
| System Type | Estimated Material Cost (Installed) | Notes |
|---|---|---|
| Standard AC Unit | $3,500 – $6,000 | Good for cooling only. |
| Heat Pump | $4,500 – $7,500 | Efficient heating and cooling; popular in NC. |
| Dual-Fuel System (Heat Pump + Gas Furnace) | $6,000 – $10,000 | Best of both worlds for NC climate. Gas furnace kicks in during very cold snaps. |
| High-Efficiency AC Unit (SEER2 Rated) | $5,000 – $8,000 | Higher upfront cost, but saves more on energy bills. |
| Complete HVAC System (AC + Furnace) | $7,000 – $11,500 | Includes both cooling and heating components. |
Local Factors
Several local factors in Lexington influence the cost of HVAC and AC replacement:
- Permits: Davidson County requires permits for HVAC installations and replacements. The cost varies, but budget around $50 – $200.
- Installation Labor Rates: Expect to pay between $75 and $150 per hour for HVAC installation labor in Lexington. The complexity of the job (e.g., ductwork modifications, difficult access) will affect the total labor cost.
- Ductwork: Many older homes in Lexington have leaky ductwork. Professional duct sealing is crucial for efficiency and can add to the overall cost, but it’s a worthwhile investment.
- NCLIC Licensing: Always verify that your contractor is licensed by the North Carolina State Board of Examiners (NCLIC). This ensures they meet safety standards and comply with building codes.
Weather Impact
Lexington’s humid subtropical climate significantly impacts HVAC system efficiency and replacement considerations:
- Humidity: The sticky summers demand systems that excel at dehumidification. Consider variable-speed compressors, which are more effective at removing moisture than single-speed models. They run longer at lower speeds, which is ideal for dehumidifying.
- Pollen: North Carolina is notorious for its pollen seasons. Invest in high-quality air filtration, such as HEPA filters, and schedule frequent maintenance to clean coils and prevent pollen buildup. Clogged coils reduce efficiency and can damage your system.
- Moderate Winters: While winters aren’t extremely harsh, they do get cold enough to warrant a heating system. This is why heat pumps, or dual-fuel systems (heat pump with a gas furnace backup), are popular choices. The heat pump handles most of the heating needs, while the gas furnace provides supplemental heat during the coldest periods.
- SEER2 Standards: Be aware of the 2026 SEER2 energy efficiency standards. These new standards mean that older, less efficient systems are being phased out. When replacing your system, choose a SEER2-compliant model to maximize energy savings.
