How to Install an Air Conditioner: A Step-by-Step Guide

Mounting an energy star-rated air conditioner appears like a large task, but with the best tools and directions, it can be achieved. Below is a step-by-step guide to walk you through it.

1. Choose the Right Location

An air conditioner needs a place that has good airflow, preferably somewhere it won’t be put in direct sunlight and near an outlet. Ground clearance around the unit must be provided for service and proper air circulation.

2. Get the Required Tools and Equipment

Stage materials and devices for installation:

  • Drill and bits
  • Screwdrivers
  • Level
  • Measuring tape
  • Mounting brackets and screws
  • Sealant or insulation tape
  • Electrical tester

3. Install the Mounting Bracket

The mounting bracket should be installed only for units with the indoor component inside. Level off the bracket and insert screws to hold it in place. Ensure the bracket is strong enough to hold up the indoor unit.

4. Mount the Indoor Unit

Gently hang the indoor unit on the bracket. Make sure it is on level and attached securely. Join the refrigerant lines, drain lines, and wires in the indoor unit. Insulate the last two connections using insulation tape.

5. Install the Outdoor Unit

It needs to be installed in a breezy area, ideally over a slab of concrete or on some sort of metal platform. Attach the refrigerant lines, electrical wires and drainage hose to the outer unit. After all, connections are tight and secured.

6. Connect the Electrical Writing

Check all connections using an electrical tester to make sure that they are tight, and there is no power arcing outside the connection. If you are not comfortable doing electrical work, this is a good time to hire a licensed electrician.

An energy star-rated air conditioner offers efficient cooling, which means savings on energy costs. Knowledge of how to install an air conditioner correctly can improve its efficiency and lifespan.
