One: Disconnecting Your Thermostat

The most important thing you will want to do is turn the power off to the wires for your thermostat. Once the power is off, then you can remove the thermostat from the base.

When you remove the thermostat, you will notice wires coming from out of the wall. These wires will be connected to the base. Before you disconnect everything, its a good idea to have labels, so you remember where everything goes.

A split system air conditioner is a great option for keeping your home cool and comfortable in the summer months. These units are also quieter, easier to install, and more energy efficient than central air conditioning. This type of A/C is ductless, so all you have to do is install the cooling unit inside and the compressor and condenser unit outside, then run piping and a power cable between the units. If you dont want to hire a professional to install a split system air conditioner and you have some experience with plumbing and electrical work, you can install the unit on your own. Each air conditioning unit is unique to its manufacturer, but the general installation process is the same.

Location Of The Air Conditioning System

When estimating installation time, the placement of the AC unit is crucial. The first concern in regards to installing an air conditioner is the square footage of your home. The space and location of the unit will affect the heating and cooling of the room. Typically, the larger the home, the more vents will need to be installed, which will take longer.

It is advisable to provide your installers with detailed descriptions of the proposed installation location, such as the height and how to access it. The air conditioning service company will also give an initial inspection before installing the air conditioner.

The inspection should usually take less than an hour unless there are some serious issues with your home. Your air conditioning service company will give you a rough estimate of how long it would take to install an air conditioner in your space during the initial inspection.

Factors That Affect Wire Size

Wiring Diagram For Ac Unit Elegant Goodman Condenser Wiring ...

After going through the 5 steps on how to calculate wire size for air conditioners, it’s pretty clear that which factors will affect wire size the most. However, let’s summarize them.

  • Load Wire size depends on electric current or load.
  • Wire length Long wire length can cause a bigger wire size.
  • Ambient air temperature High temperature lead to a bigger wire size.
  • Wire operating temperature High temperature allow a smaller wire size.
  • Wire material Copper is a better conductor than aluminium.
  • Wire type PVC, XLPE or armour wire have different specifications.
  • Installation Wires run on perforated cable tray perform better than enclosed in trunking.

What Is A 10/3 Wire

Here we will again apply the same logic as we did in the case of 10/2 wire.

The number 10 on the left refers to the size of the wire whereas the number 3 on the right refers to the number of conductors present in there. Therefore, a 10/3 sized wire means that it has 3 strands of 10 gauge conductors along with a ground wire. Or in more simple words, a 10/3 wire means that it has two 10 gauge hot wires , a 10 gauge neutral wire , and a 10 gauge ground wire .

Installation Of The Condensate Drain Line

The moisture removed from the home during the cooling process travels down a plastic PVC pipe. It must be connected to the primary side of the evaporator coil. The evaporator coil has a primary and a secondary drain location. The primary condensate drain line will travel from the indoor evaporator coil to an appropriate floor drain or condensation pump.

A condensation pump is used where a proper floor drain does not exist in the home. There are also other reasons where a condensate pump is required or is beneficial to install. The important thing to remember if a condensate pump is used is that it must be serviced a minimum of twice a year to maintain proper performance.

Any condensate tubing or piping should be secured and glued with the proper cement. A trap and an overflow safety switch must also be installed in the condensate system. This is to protect the equipment and the area from flooding due to a restriction. The safety overflow switch is connected to the secondary port on the indoor evaporator coil and wired into the furnace control to shut down the system when it is tripped.

Type Of Air Conditioning Units

The type of AC system also contributes to the total length of time. Here are some of the types that are usually seen at home:

Split System Air Conditioner

A split unit air conditioner is a type of air conditioning system that consists of two independent units: the condensing unit and the air handling unit. The split air conditioner is a wall-mounted type. Installing a split-type air conditioner is the simplest, and therefore can be done in a short time.

Window Air Conditioner

Since window air conditioners come in different sizes, they would be suitable if youre looking to cool a single room or a small area. Just like a split-type air conditioner, a window-type unit is a wall-mounted type, so it is easier to install.

Central Air Conditioner

A central air conditioning unit is more costly than any of the other varieties described, but it is also more effective. A ceiling cassette or concealed type is more complicated. Therefore, it may require more time to install compared to other types of air conditioners.

How Long Does It Take To Install An Air Conditioner

Knowing exactly how long it will take to install a new AC unit and what work must be done is an important factor in making your next move in replacing or installing a new air conditioner in your house. If you are wondering how long it will take to install an air conditioner, you are in the right place.

Drawback #: Length Of The Job

When youre working on a project alone, it can take a lot longer than if an experienced team handled the details. Especially if youre unfamiliar with HVAC work, it could take a lot longer for you to install a new AC unit than it would for a contractor and a team to do it.

Also, you wont be earning a wage for your hours, meaning your time investment could wind up costing more than if you paid someone else to handle it.

No Manual Labor For The Homeowner

If youre DIYing the job, you may be crawling under your home, lifting heavy parts, preparing an installation site, pouring concrete, climbing on the roof, or any number of other physical tasks. Hiring a professional eliminates the need for you to do anything other than sign off on the work and pay the bill.

The Wire Will Stay Cool

Using the right wire for the air conditioner has a lot of benefits and one of them is excellent safety. The current will face minimum resistance while flowing through the wire, this way the wire will stay cool and safe. It will reduce the risk of any fire, short circuit, or electrocution. Thus, it will save the air conditioner as well as your life and loss of property.

A 10/2 wire is the best choice for an air conditioner as compared to a 10/3 wire.

A 10/3 wire has 2 hot, 1 ground, and an additional neutral which is not even needed for an air conditioner. Therefore, it is recommended that you must use a 10/2 wire having 1 hot, 1 neutral, and 1 ground which is the perfect choice for an air conditioner.

What if there is no C wire for the thermostat?

Electrical Wiring Of Split System Air Conditioners

Wiring An Outdoor AC Unit

Energy Safe Victoria has become aware of a technical issue with the installation of wiring between the outside unit and the indoor unit on various split system air- conditioners.

The photo depicts the connection of the wiring installed between the outdoor unit and the indoor unit that has been connected / terminated incorrectly and does not comply with the conductor insulation colour identification requirements of Clause 3.8 of AS/NZS 3000:2007.

The technical issue is with the interconnecting cable terminals of both the indoor and outdoor units these terminals are labelled S1, S2 & S3 but are also distinguished by use of colour

Communication no issue

Electricians are incorrectly connecting the wiring installed between the indoor and outdoor units to the terminal colour coding, resulting in the black conductor becoming an active conductor, the white conductor becoming a neutral conductor and the red conductor being communication.

The wiring installed between the outside unit and the indoor unit is classified as installation wiring and shall comply with the conductor insulation colours as specified in Table 3.4 of AS/NZS 3000:2007.

Should an electrician encounter this situation, immediate rectification is required.

It is most important to isolate supply, test before you touch and Lock out Tag out before starting work.

Wiring Between Disconnect Switch To Contactor:

Starting with the 240V power supply coming from disconnect a lot of times itll be a red and a black wire along with the green wire that is in there.

And you got your disconnect thats probably gonna be mounted to the side of the house itll either be a lever or breaker type.

Basically, you have 240 volts coming from your circuit breaker panel its your disconnect from the house and then from there, it goes through the electrical whip and into the contactor.

So this electrical whip will have three wires usually theyre gonna be black red green. The black wire will go to one side of the contactor then we got a red wire that will go to the other side of the contactor.

And then we have ground wire just gonna be a green that will just be mounted to the chassis. The condenser unit will have a little square screw-like strap that you put the ground wire into.

So now we have our main power supply hooked up each of the power wires is 120 volts to give us 240 volts. Those two wires are hooked up to the contactor on the L1 and L2.

This table shows the most common colors for each function. However, your wires may not be the same as the colors in the diagram. If theyre not the same, check the manufacturer and get the correct correlations.

For instance, the wire for cooling may be blue instead of yellow. Thats important to know when hooking up an AC unit to your thermostat. Also, there should be a jumper wire between RH and RC. If your jumper wire is not there, your air conditioner will not power on and off.

How Does The Contact Terminal Operate Your Air Conditioner

The two wires that you attached to the contact terminal sends power through the terminals coil. The coil will draw 24 volts from the control board, which will suck a plunger in on the contact.

Once the plunger draws into the contact, the volts will then be allowed to go through the terminal. When the plunger relaxes, the power will stop flowing through.

Your portable AC needs several feet of unobstructed floor space so it receives adequate airflow. You also need to have easy access to the water reservoir. While you may have a long ventilation hose, your portable air conditioner will run more effectively if it’s closer to the window. This will allow more of the warm air to be vented outside instead of back into the room. If your portable air conditioner comes with a hose that lets it drain continuously, you may need to place it near a sink or tub, or use a bucket.
