AC Installation Tips

If you’re planning to install an AC yourself, it’s important to have the proper tools and supplies. You’ll also want to keep in mind the etiquette of tipping an horne AC installers.

A properly installed air conditioner helps keep your home comfortable all year round. It’s essential that your ductwork is well-insulated and sealed, which improves energy efficiency.

Preparing the Area

The window air conditioner you choose should be the right size for your home. An undersized AC won’t keep your house cool, while an oversized unit will consume excessive energy.

You should also make sure that your windows are in good condition and that the frames can support the weight of the new unit. A window air conditioner should also be firmly fastened to the wall using metal brackets or interior angles.

Clear a Path for the Contractor

Before the crew arrives, remove furniture, toys, decorations, and other items that could obstruct their work. This will minimize the risk of property damage and accidents.

You should also have a power outlet available for the AC. It will need a power source connected to your home’s meter, and if you don’t have one yet it will set the entire install back. Also, it is a good idea to keep the AC out of direct sunlight, especially in South Florida.

Mounting the Unit

Some window air conditioners come with brackets that transfer the weight of the unit more evenly so it doesn’t place all of the weight on the windowsill and sash. Check your manual to see if yours does.

Before you start working, clear your workspace and make sure that you have everything you need to complete the job. That includes an extra pair of hands and the tools you need, like a screwdriver, measuring tape, scissors and more. It’s also a good idea to find an assistant because window AC units are heavy and can easily damage your windowsill, sash or other property if dropped.

Before you begin, you’ll need to drain the refrigerant from your old air conditioning unit if it still has refrigerant in it. It’s important to do this because the backside of an AC unit has thin cooling fins that can cut your fingers. Moreover, you should never attempt to remove refrigerant from an AC unit yourself without proper training and handling certification from the EPA.

Installing the Indoor Unit

When mounting the indoor unit (also known as an evaporator), you’ll need to find a suitable location. For best results, select a spot that’s away from direct sunlight or any heat sources and at least 6 to 7 feet from ceiling. The location should also be free from items like antennas, TV cables, telephone lines, and electrical wires.

You’ll also need to make sure the studs are solid and clean so you can mount the evaporator. Once the studs are in place, you can mount the wall plate.

Next, you’ll want to run the line set. This includes the refrigerant lines, drainage tubing, and control wires. First, turn off the power to the evaporator and cut a 2-3 inch hole in the wall. Then, remove the outer shell and carefully feed the pipes and cable through the hole in the wall. Secure them with electrical tape.

Installing the Outdoor Unit

When installing the outdoor unit of your split AC, you should make sure that it is on a flat and rigid surface. Otherwise, the unit might vibrate excessively. This can lead to the breakage of copper pipes, coolant leaks and fan motor damage.

It is also important to keep the outdoor unit away from heavily trafficked and dusty areas. The pipe that connects the indoor and outdoor units should not be bent more than three times. The more bends in the pipe, the less efficiently your air conditioner will work.

Another important tip is to check for duct leaks. If the cool air is not circulating properly, you may have to clean the ducts and install new seals. A good way to do this is to walk along the length of your ducts and look for any gaps or leaks. You can also use a smoke meter to detect duct problems. Tipping your HVAC installer is a great way to show your appreciation for their work. However, be careful not to tip if the job was done poorly or if the company has a policy against it.
