As global temperatures increase, air conditioning has become a necessity. A functional AC works round the clock to keep the building and occupants cool. Installing an AC isn’t a straightforward task. An AC installation mistake, no matter how minor it may seem, can affect the performance of your AC and reduce its useful life. An AC installation contractor, Bethesda is equipped to manage installation complexities and come up with an effective installation plan.
Here’s a step-by-step AC installation guide.
Choosing the Right Unit
We cannot emphasize enough the importance of the right size AC unit for your home. An oversized AC consumes more electricity and can short cycle, whereas an undersized unit fails to cool your rooms evenly. To determine the right size AC for your home, your HVAC contractor performs some calculations. Before buying an AC for your home, check its EER rating. The higher the EER rating of an AC, the more efficient it is.
Selecting the Right Location
The next step involves deciding where to place your unit. This is an important decision as your AC’s location can affect its performance. For a window AC, select a window with proper support and make sure there’s an electrical outlet nearby. The selected window should allow for unobstructed airflow. If you want to install a split AC, your contractor mounts the indoor unit on a sturdy wall (should be away from heat sources) and places the outdoor unit on a flat surface.
Preparing the Installation Area
Your contractor removes dust and debris (can interfere with the installation process) from the installation area. They check the wires and circuitry to make sure they’re in good condition. Any necessary repairs are performed before proceeding to the next step.
Installing the Mounting Bracket
A mounting bracket keeps your AC in its position. Your contractor attaches it to the wall using screws and anchors to ensure that it can support the weight of your AC. When installing a window AC, AC installers use a mounting bracket to secure the main unit. The bracket is fastened to the window with screws and anchors.
Installing the Indoor and Outdoor Unit
With the mounting bracket securely in its place, your contractor mounts the indoor unit onto it. They make sure that the unit is level and horizontal and securely fastened to the bracket. Next, the outdoor unit is placed on a flat surface. Your contractor ensures that there is at least two feet of clearance on all four sides.
Connecting the Refrigerant Lines and Electrical Wires
Your contractor carefully connects the refrigerant lines according to the manufacturer’s instructions. Next, they connect the unit to a dedicated electrical outlet and turn it on to see if the system is working properly. After installing your unit, the professional checks for any unusual noises, leaks and airflow problems.
Post- Installation Tasks
Here are some post AC installation tasks that your contractor performs to ensure the unit performs flawlessly.
Sealing any Gaps
Your contractor uses foam or other insulating materials to seal gaps around the AC unit to prevent leaks. The window is weather-stripped to ensure a tight seal between the system and the window frame, which improves the unit’s energy efficiency.
Final Checks and Adjustments
The final step involves inspecting the system one last time. An in-depth inspection can reveal problems that can affect the system’s efficiency. Typical examples include loose connections, leaks, and airflow problems. Your contractor ensures that the outdoor unit is level. Any issues are addressed to ensure your AC functions smoothly.
Some AC installation mistakes to avoid
- Selecting the wrong-sized (an undersized or oversized) unit
- Installing the indoor unit in an area that is close to heat sources and the outdoor unit in an unshaded spot
- Failure to seal gaps around your AC unit
- Not checking for refrigerant leaks
- Improper vent positioning
