Guide To Installing An Air Conditioning System


Anyone who has ever endured the heat of summer without a working air conditioning knows this system’s importance. If you have some DIY skills, and you’re brave enough to install the AC unit by yourself, you must be prepared to put in the time. You will save on the installation cost and you can be proud of the work you’ve done after the installation.

How to Plan for the Installation

If you’re not careful, you may end up wasting your time and money as you try to install the air conditioning system, so proper planning is crucial. To get the most from your air conditioner, you must ensure the power supply to the air conditioning unit will be enough to power the air conditioner effectively. If not, you may have to get a new circuit breaker with a higher current rating. If you encounter a challenge, be sure to get in touch with a professional for assistance. They are just a call away!

The Installation Process

The first item to install is the air handler, so you’ll need to identify a suitable space in your attic, garage, or basement to install this unit. Most units come with installation instructions, so you just need to follow those instructions before plugging the unit into the power supply.

Since you’re not interested in getting electrocuted, it’s recommended you turn off the power at the main switch. Be sure to take your time to identify the main control panel in your home or building and turn off the power before you start the installation.

Once the air handler is installed, the next step is to install the condenser/compressor. This unit must be installed outdoors, either on the wall, ground, or rooftop. During installation, make sure the ground or wall is stable enough to hold the weight of the compressor and sustain the vibration of the compressor motor.

Tool Time

During installation, you will have to use several tools. For starters, you will need to use an electric drill to make holes through the wall to run electric wires and refrigerant tubing to connect the compressor and air handler. After installation, be sure to use a filler to seal any gaps in the wall. Before connecting the system to the power supply, make sure you’ve installed a thermostat to control the system. All electrical connections must be ready before the air conditioning system can be powered on.

After double-checking everything, turn the power back on and confirm both the air handler and compressor are running. You’ll need to have a bit of electrical knowledge and some DIY skills to be successful. In case of difficulty, be sure to consult an HVAC contractor.

The Importance of Location

Window AC units are easier to install. However, you must identify the right window to install the unit. Be sure to keep in mind the size of the window unit because it may not fit on your window opening. You’ll have to use a tape measure to prevent any inconveniences.

Once you’ve found the right window AC unit and the right window, locate the mounting brackets and attach them properly. The mounting instructions are usually provided in the user manual. You’ll also need to use the piece of foam that comes with the unit to seal the window to prevent air leaks around the window unit. If your unit does not come with a piece of foam, you will need to find an alternative. By sealing air gaps, you’ll be able to prevent hot air from the outside from getting into the house through the window.

Locate the drain pipe that comes with the air conditioner; most units usually come with a drainage hose. If your air conditioner did not come with this pipe, you can purchase a drain hose at a nearby home improvement store. Be sure to use caulk around the outside of the window unit to seal any air gaps you might have overlooked. This is crucial in separating the indoor and outdoor environments.

Lastly, connect the window unit to the power source and adjust it to ensure it cools your home properly.
