Once you have decided to replace your air conditioner, the next question is usually how long you will be without cooling. Here is a realistic timeline for a Sacramento install, and what can stretch it.
Quick answer
A standard AC replacement usually takes 4 to 8 hours, completed in one day. A full HVAC system swap or one needing new ductwork can take two to three days. Factors like home age, attic access, and permits affect the schedule.
A standard AC replacement
If we are replacing a like-for-like system with existing, sound ductwork, most installs are done in a single day, roughly 4 to 8 hours. That includes removing the old unit, setting the new one, making connections, and testing.
A full system or new ducts
Replacing both the AC and furnace, upsizing the system, or installing new or repaired ductwork extends the job to two or three days. Ductwork in particular is labor-intensive in older homes.
What affects the timeline
- Home age: older Sacramento homes may need electrical or duct updates.
- Access: tight attics, crawlspaces, or rooftop units take longer.
- Permits and inspection: required for new systems and scheduled accordingly.
- System type: mini-splits and packaged units differ from standard splits.
How to prepare for install day
Clear a path to the indoor and outdoor units, secure pets, and plan for the system to be off during the work. We protect floors, clean up fully, and walk you through the new system before we leave.
