Installing a new HVAC system can be a complex process, and the amount of time it takes to complete the installation will depend on several factors. We could say that it only takes one day, but considering all the processes combined, it could take between three and six days. The type of system you want to install will also influence the amount of time it takes. Simple installations, such as replacing an oven, can be done by an HVAC professional in one day.
If you want a more complex installation, such as a central air conditioning unit, it can take a couple of days. In most situations, the actual installation will only take a few hours. However, an HVAC professional will likely have to perform an inspection beforehand. If you need a simple system change, the time required will be shorter than if your installation requires replacing the ducts or replacing the entire system.
Spacing, measurements of the area in which it will be installed, and the installation of ducts if it is the first unit to be installed in the house are all important steps that must be taken into account. The technician may also have other problems when performing a full installation of the system, making it more difficult to reduce the time for this situation. Typically, the full installation of an air conditioning system will take three to five days to complete. If ducts or thermostats need to be replaced or rewired, this can add additional time.
Another thing that will affect the time it takes to install your new air conditioning system is the company you choose. Often times, an air conditioning company will have additional technicians for larger installations like this, so time isn't always a factor, but just in case, you should plan for more time.
