One of the most common questions we get is how long does it take to replace an AC unit? Well, it really depends. For example, the complexity of the work, the condition of the system and the need for additional installation steps. Let's find out together how to determine terms for your specific case.
What’s the Typical Timeline for a Central Air Conditioning Unit Replacement
So, finally: how long does it take to replace an HVAC system? Normally, it’s a matter of 4-8 hours. If your old unit can be easily dismantled and the new one is similar, the installation time is reduced.
During a central air conditioning unit replacement consider these points:
- availability of the outdoor unit;
- type of system (split, multi-split, ducted);
- the need to replace the thermostat or electrical components.
How Long Does It Take to Replace an HVAC System vs Just the AC Unit
If you need not just a central air conditioning unit replacement but also new heating equipment, the installation takes longer. A complete HVAC system replacement requires from 1 to 3 days.
AC replacement time for a split system alone is a matter of hours. But if you decide to completely replace your cooling and heating equipment, the best decision is to take into account additional testing and tune-up.
Factors That Affect AC Replacement Time
Many factors can affect AC replacement time:
The age of the system
Old wiring or damaged pipes can make installation more difficult.
Accessibility
Narrow attics or hard-to-reach areas are a real challenge even for pros.
Additional work
This may include replacing the thermostat, reinforcing fasteners, or even connecting to a smart home.
The Step-by-Step Process of an AC Replacement
This is a simple procedure that will help you understand how long does it take to replace an AC unit:
- Disconnecting the old system. This means dismantling and removing the old unit.
- Preparing the utilities. You should assess the condition of cables, pipes, brackets.
- Installation of the new unit. And all you need during the process: fixing, connection, adjustment.
- Testing. Checking pressure, temperature, leaks.
Same-Day Installation: Is It Possible for AC Units
Yes, sure! The same-day installation is possible. Especially if:
- the unit has already been delivered;
- the electrical system is ready;
- the home service company has carried out measurements in advance.
Any unexpected things can make AC installation time increase though.
Time Breakdown: AC Unit Removal vs. New Installation
Keep in mind that removing takes 1-2 hours. A new AC installation time is different though: up to 5-6 hours, because we shouldn't forget about tests and programming.
So, if you're wondering how long does it take to replace an HVAC system, count on a full day. Especially if the unit is on a roof or under an awning.
Do Ductwork Repairs Extend AC Replacement Time
The short and simple answer here is yes. If the air ducts are damaged or don't match the new equipment, this adds 1 to 2 days. If the ductwork is completely replaced, the time adds up to a week.
How Long Does It Take to Replace an Outdoor AC Unit
The truth is that it takes 2-4 hours to replace an outdoor unit itself. But to that time you should add setting up the indoor units, especially if they are in different rooms.
Typically, in a standard central air conditioning unit replacement, both the outdoor and indoor units are changed at the same time.
