How to Install Air Conditioning Units

Before attempting to install an air conditioning unit, it is important to know how to properly inspect the area and size it. Remember to always follow the manufacturer’s instructions for safety and proper sizing. The following guide will cover all of the major steps in installing a Lakewood air conditioning unit. If you are unsure of any of these steps, consider hiring a professional to do the job for you.


Before a homeowner opts for the installation of air conditioning units, they should ensure that the primary systems are operational and in proper working condition. They should also ask about any possible rebates or tax credits. Additionally, they should prepare the home for installation to ensure that the process goes smoothly and without any problems. Performing these steps can help homeowners enjoy energy-efficient home cooling this summer.

Make sure the window has a firm structure, such as masonry or wood. Using the manufacturer’s installation manual, follow the steps to ensure proper air conditioning unit installation. It’s important to secure the unit on the window frame by securing it with metal brackets and interior angles. These angles must be sturdy enough to support the weight of the air conditioning unit. If the window cannot support the weight of the air conditioning unit, the window frame may not support it.


Regular inspection of air conditioning units is a vital part of preventative maintenance. If not done, poor air quality can compromise your comfort and pose severe health risks. Exposure to indoor pollutants, such as dust and mold, can contribute to respiratory ailments and worsen other medical conditions. Having a qualified technician check your unit can help you avoid these problems. Here are some tips for inspecting your air conditioner.

When inspecting your unit, make sure you know the correct service mode. Sometimes air conditioning units operate in fan or heating modes. It is imperative that your air conditioner is in cooling mode. Look for an icon that indicates which mode your unit is in. If it has two modes, it is best to leave it in cooling mode. If it does not, you can always contact an HVAC professional for help. You may also want to check the level of the unit on a level surface. Lastly, ensure that refrigerant lines are not stressed.


Sizing an air conditioning unit depends on a number of factors, including the size and type of room. The chart below is a good starting point for determining your AC size. The chart assumes a room with 8-foot ceilings, one door, and two windows. However, the size and type of AC you need will depend on many different factors, including the material of the walls, the temperature difference between the room and outside, and the location of the room in the house.

Modern homes are usually more energy-efficient than older houses. They typically have more windows and greater open space, making them a better place to install an AC system. Older homes may not have the insulation and require a larger AC system. Other factors to consider when sizing an air conditioner include the type of ductwork


Before installing air conditioning units, you should consider safety measures. The first step is to secure the outside of the building where the unit is to be installed. Place a strong padlock on the AC disconnect box. This will deter most thieves. It is also a good idea to install a motion sensor light and place outdoor lighting aimed at the unit. These measures will deter thieves and will help keep your home safe from intruders.

Next, determine whether the air conditioning unit will fit the room. If you are not sure, you can ask a professional to install it for you. Also, make sure to check the air intake. Make sure that the unit is not near water. Also, make sure that the cords are secure and that they are not frayed or loose. Remember that smoke detectors can be deadly. Install them on every level of the home. Check the batteries every month and replace old ones if they become weak or broken.


Building permits are required to install any major appliance in a residential property. Depending on the size and complexity of the project, a building permit may be required for major HVAC upgrades. Building permits for home improvements are also necessary for the installation of air ducts, fireplaces, and furnaces. Obtaining the proper permits for these projects will ensure the safety and efficiency of the new HVAC system, as well as give you a paper trail of your work, which can prove useful when selling your house.

Obtaining permits for HVAC installation is often a complicated process. Local codes may differ from state to state, and municipal governments may have different rules. In some cases, you may not need a permit at all if installing a mini-split air conditioning unit will not alter the frame or alter the structure of the building. To find out if a mini-split unit requires a permit, contact your local building code office.

Choosing a contractor

Before hiring a contractor to install your air conditioning unit, you should research the company. Read online reviews and look up complaints and ratings. While the company should have a clean history, fake reviews are still out there. Although sites such as Yelp filter reviews, there is still no guarantee. It is still best to use common sense when selecting a contractor. Check out their website and read the comments from previous customers.

Make sure the contractor is experienced with your particular brand. You can check with the state contractor’s office or simply Google the contractor’s name. Another good tip is to ask for referrals from friends and relatives. Getting a referral is a great way to ensure the best results for your air conditioning installation. Getting multiple quotes is also a good idea so you can compare costs and quality. After all, you only want the best.
