How To Install a Window Air Conditioner in 5 Steps

With a window unit, you can enjoy a cooler and more comfortable living space, avoiding a central AC installation. A central AC unit installation is best left to professionals. However, you can attempt DIY with a window unit. Here’s a 5-step guide to installation, particularly for a window air conditioner.

Step 1: Collect Necessary Equipment & Tools

Collect all the equipment and tools required for AC installation. Having these items near you will make the process easy for you. First and foremost, buy a window AC.

You will need window mounting brackets, a screwdriver, measuring tape, level, foam weather stripping, safety goggles, gloves, and a helper.

Step 2: Choose the Right Window

For your air conditioner installation, you must select the right window.

The window should be close to an electrical socket and capable of supporting the weight. A double-hung window is generally easy to work with.


Take precise measurements of the window’s width so that you can confirm the air conditioner fits perfectly.

Step 3: Prepare the Outdoor Unit

Clean the outdoor area of the window to remove any dust. Now, attach the mounting brackets to the window frame. Thus, the window can support the air conditioner well.

Step 4: Install the Air Conditioner

Finally, it’s time to put in the air conditioner. Place the device on the window’s mounting brackets. Make sure it’s centered and balanced. Extend the side panels of the air conditioner to fill any gaps. For the correct attachment locations, follow the manufacturer’s guide.

Step 5: Test and Maintenance

You are not done yet. Plug in the device and test its performance. Make sure it’s cooling the room efficiently. Notice if there are any unusual sounds or signs of water leakage.

You need to do regular maintenance to keep your window air conditioner well-functioning. Clean the air filter and condenser coils regularly. If you face any complex issues, don’t hesitate to consult an HVAC professional.

Should You Install Your AC Yourself?

AC installation requires technical expertise, including knowing about the electrical work and handling refrigerants. It can be complex and potentially dangerous. Professionals have proper safety equipment, knowledge, and experience. Moreover, without expertise, you may end up damaging the new AC unit and require premature and unnecessary repair.

In addition to these concerns, warranty coverage is a significant factor too.


A manufacturer warranty is a huge advantage for homeowners. It may offer free or discounted repairs within a limited time frame under the conditions applied. However, a DIY installation may void the warranty and expose you to more expensive repairs. Energy efficiency is also a valid reason to choose professional installation. Properly installed AC systems work more efficiently, which lowers energy consumption and reduces utility bills over time. Again, installing on your own might take longer, while professionals can do it quickly and save you fast from the uncomfortable environment.

Objectively speaking, it is best to call a professional for AC installation than to attempt DIY. It’s always wise to leave it in safe hands.

How To Find a Professional AC Installation Service in Houston?

Now, if you’re convinced to call a professional to get your air conditioner installed, you need to know how to find one. Houston offers a number of AC servicing companies.

However, while choosing a company for AC installation, seek reviews, opinions, and recommendations from close ones or netizens.

Verify if the company is authorized to serve in your area by checking their license. Technicians should also have certifications as proof of their expertise.
