A standard HVAC installation or replacement for homes usually takes 1 to 3 days. A simple, like-for-like system change-out can often be completed in 4,8 hours (one day). More complex projects, such as full system installations in larger homes or homes without existing ductwork, may take up to a week.
Many people need a complete HVAC installation, including ductwork, indoor and outdoor units, and proper electrical connections. At Greg’s Air Solutions LLC, we handle every step of the process. Our team designs a custom system layout, installs high-efficiency equipment, and ensures all ductwork and wiring are installed perfectly. We also manage permits and inspections, so homeowners don’t have to worry about compliance or delays.
With Greg’s Air Solutions LLC, every installation is completed by licensed technicians with years of experience. We make sure the project is efficient, safe, and tailored to your home’s specific needs, giving you a comfortable, energy-efficient environment from day one.

Key Factors Affecting HVAC Installation Time
1. Type of Installation
- Replacement: Quicker because existing ductwork and electrical connections are reused.

2. System Type and Complexity
- Central AC/Furnace: Usually 4,8 hours if infrastructure is ready.
- Mini-Split Systems: Each indoor unit adds a couple of hours.
