How long does an HVAC replacement take?

The typical HVAC replacement in Hillsborough takes 1-3 days, depending on the complexity of the installation and any necessary ductwork modifications.

Do I need to replace my furnace and AC at the same time?

While not always mandatory, replacing both simultaneously is often more cost-effective in the long run. Mismatched systems can reduce efficiency and lifespan. Also, it's crucial when dealing with refrigerant phase-outs as older AC units may use refrigerants that are no longer produced, making repairs difficult.

What size HVAC system do I need?

The correct size depends on factors like your home's square footage, insulation, window efficiency, and climate. A professional HVAC contractor will perform a load calculation to determine the appropriate size for your home.

Material Prices

While ‘material’ isn’t directly categorized as vinyl, wood, or fiberglass in HVAC systems, here’s a breakdown of common HVAC equipment and their approximate costs:

Equipment Type	Average Price (Installed)	Notes
AC Unit (Standard Efficiency)	$3,500 – $6,000	Good for basic cooling needs.
AC Unit (High Efficiency – SEER2 16+)	$5,000 – $8,000	Lower energy bills, better dehumidification.
Heat Pump (Standard Efficiency)	$4,000 – $7,000	Provides both heating and cooling.
Heat Pump (High Efficiency)	$6,000 – $9,000	More efficient heating and cooling.
Gas Furnace	$3,000 – $5,000	Used in dual-fuel systems, typically with a heat pump.
Dual-Fuel System (Heat Pump + Gas Furnace)	$7,000 – $11,500	Optimal for NC climate – efficient heating and cooling.
Ductwork (Replacement/Sealing)	$500 – $3,000+	Crucial for efficiency and air quality. Price varies greatly on the size and state of the system.

Local Factors

When budgeting for your HVAC or AC replacement in Hillsborough, keep these local factors in mind:

Permits: Orange County requires permits for HVAC replacements. The cost varies, but typically ranges from $50 to $200 depending on the scope of the project. Your contractor should handle obtaining the necessary permits.
Installation Labor Rates: Labor rates in the Hillsborough area typically range from $75 to $150 per hour for qualified HVAC technicians. The complexity of the installation (e.g., modifications to ductwork, difficult access) will affect the total labor cost.
NCLIC Licensing: Always verify that your HVAC contractor is properly licensed by the North Carolina State Board of Examiners (NCLIC). This ensures they meet the state’s requirements for competency and insurance. Don’t risk hiring an unlicensed contractor!
Ductwork Considerations: Many older homes in Hillsborough have aging or leaky ductwork. Addressing ductwork issues (sealing or replacement) during your HVAC replacement is highly recommended to maximize efficiency and improve air quality. Remember that starting in 2026, North Carolina adopted the SEER2 efficiency standards, which will require even greater attention to your ductwork.

Weather Impact

Hillsborough experiences a humid subtropical climate, characterized by hot, humid summers and mild winters. The high humidity levels place a significant demand on air conditioning systems. Key considerations for HVAC & AC Replacement:

Dehumidification: Choose a system with excellent dehumidification capabilities. Variable-speed compressors are highly recommended as they can run at lower speeds for longer periods, effectively removing moisture from the air. This leads to improved comfort and reduced energy consumption.
Pollen: North Carolina is notorious for its heavy pollen seasons. Invest in high-quality air filters (HEPA filters are a good option) and schedule regular maintenance to clean the coils and prevent pollen buildup. Pollen reduces efficiency and can damage your system.
Heat Pumps: Heat pumps are a popular choice in Hillsborough due to the moderate winters. Consider a dual-fuel system (heat pump + gas furnace) for optimal efficiency. The heat pump can handle most heating needs, while the gas furnace provides supplemental heat during colder periods.
