On a new home, an addition or a major remodel, HVAC isn’t a single installation day — it’s woven through the whole construction schedule. Getting the timing and coordination right avoids costly rework and inspection delays. Here’s how homeowners, builders and general contractors can plan.
Plan the system early
The best time to design the HVAC system is before framing is finished. Early planning lets you:
- Size the equipment from the actual plans
- Reserve space for the air handler, returns and duct runs
- Locate the outdoor unit where it’s practical, serviceable and properly secured
- Coordinate electrical requirements and condensate drainage
Typical stages of HVAC work
- Rough-in: ductwork, refrigerant lines and drainage installed while walls and ceilings are open.
- Rough inspection: the work is inspected before it’s covered.
- Trim-out / equipment set: equipment, grilles and registers installed after finishes.
- Start-up and testing: the system is charged, tested and balanced.
- Final inspection: needed before the project can close out.
Additions: can the existing system handle it?
A common mistake is simply extending ductwork from the existing system into a new addition. If the current equipment doesn’t have the capacity, both the addition and the rest of the house end up uncomfortable. Options include:
- Upsizing or replacing the existing system
- Adding a separate system for the addition
- Using a ductless mini-split for the new space
Working with your general contractor
