Spring is a great time to get a new AC system installed into your home. Perhaps you’re upgrading your system or replacing one that’s no longer working well. Regardless of the reason, you can rest easy knowing your new unit will keep you cool during the Decatur, AL summer.

You’re likely wondering what will happen during your installation and how long it will take. The length of time will depend on what type of air conditioning system you’re getting, but expect the work to take a day or two.

When expecting an AC installation or replacement, be sure to:

  • Have an adult at home during the length of the installation.
  • Allow enough space for your HVAC professionals to work.
  • Have a list of questions ready about your new unit, if needed.
  • Ask beforehand if ductwork will need to be replaced, as this can increase cost and installation time.
  • Keep any pets secured.

Your HVAC professionals should give you a time and date when they’ll arrive at your home. Once they arrive, they’ll assess your unit, ductwork, and any other parts of your system including your thermostat.

Next, you can expect your HVAC company to take out the old equipment that you’re replacing, unless you are in a new house that’s getting its first air conditioning system. This step can include:

  • Unhooking and possibly taking out the old ductwork. Ductwork will be removed if you’re having this part of your system replaced, which may be necessary for some newer central air units. Ductwork isn’t needed for split systems, in which the outer and inner part of your AC unit is connected through a single wall.
  • Any vents will also be disconnected.
  • Removing the old control wiring and moisture drain.
  • The outside system will be unhooked and removed if it’s a central AC system.

Once the work area is prepped, installation will begin. Both central AC and split systems will require some indoor and outdoor work.

Indoors, expect your professionals to:

  • First install any new wiring or ductwork that’s needed for your new system. This step can vary, and split systems won’t need new ductwork, leading to potentially shorter installation times.
  • Install any new gas lines that are needed and check for any leaks of both gas and air in the system.
  • If replacing ductwork, insulation may need to be added as well.
  • Install or adjust any new vents.
  • Add new valves for refrigerants, which help to keep your home cool and collect humidity.
  • You’ll likely be upgrading your thermostat, possibly to a smart thermostat.

Outdoors, the installation time and work will vary based on your chosen AC type. If you’re getting a new central AC system, the outer unit will need to sit on a pad and be leveled so that it works properly. An outside unit will also need to be installed for a split system.

Once your system is fully installed, your HVAC professional will then test your system to ensure that everything is working properly.  This will include running the thermostat, answering your questions, and checking the system for leaks.
