Are you thinking about purchasing a new AC unit for your home or business? If so, you’ve probably found yourself asking: “How is an AC unit installed?” and “Is it really worth the cost to have a professional do it?”

How is an AC Unit Installed? 5 Important Steps

Generally, you can expect a professional AC installation to take anywhere from 8 to 14 hours. While each installation is different, most require the following five steps.

1. Pre-Installation Evaluation

First, an experienced AC tech will come out to your home and evaluate your current system. A “Manual J load calculation” will determine how much heat your home or business gains during the day and what size AC unit you need to keep the space cool.

During this evaluation, you may want to ask the tech: “How is an AC unit installed in this space?” This way, you can hear the details about what to expect during your specific installation process. You should also receive a written quote with all of the costs and details.

2. Removal of the Old AC System

If you already have an HVAC system in place, the next step is to remove the old equipment. To do this, the crew may need to access your crawl space and/or attic area. They’ll remove any refrigerant from your current system, then take it apart and get it out of the way.

3. Duct Repair/Modification

Ductwork isn’t always a part of how and AC unit is installed. However, it’s common to need some ductwork repairs or modifications. If this is the case, it should have been included in the quote you received.

Making sure your ductwork is in optimal shape is an important part of ensuring that your new system works correctly.

4.  New System Installation

The actual system installation may involve work both inside and outside your home or business. The crew will expertly install each component. This may include:

  • Inside air handler/evaporator
  • Outside compressor/condensing unit
  • Refrigerant supply lines
  • Thermostat
  • Condensate drain lines
  • Condensate pump

They may also need to upgrade your wiring and circuit breakers. If major electrical work is necessary, you might also need a licensed electrical contractor.

5. Testing Your New System

Finally, your installation crew will perform pressure and vacuum tests. Then, they’ll give your system a complete inspection and charge it with refrigerant. Finally, they’ll activate the system and test it one last time to ensure that each component works properly.

Before they leave, the crew will show you how to properly operate the new system, including the thermostat. This is also a great time to ask about the warranty and rebate paperwork. The AC company will usually complete and file this for you, but it’s a good idea to double-check.

Benefits of Professional Installation

Now that you know the answer to the question: “How is an AC unit installed, it’s easy to see why you would want to leave this project to the pros.

According to the Environmental Protection Agency (EPA), almost half of all HVAC systems are installed incorrectly. This leads to an energy efficiency loss of up to 30%, costing you money and damaging the environment. Even worse, you’ll constantly struggle to keep the space at a comfortable temperature!
