When you want to install your own air conditioner, you need a basic guide that will make the process simpler. In most cases, you are living in a home that already has an AC unit. At the same time, there may be instances where the house never had central air. If you do not yet have an internal furnace, you must ensure that the furnace has been installed by a professional. You can do much of the work on your own when you are handling the AC, and you can follow each step in the process to get amazing results.

1. Where Is The Condenser?

Your condenser should be located outside, a few inches from the house, and on a flat surface. If you have a condenser, you can remove that condenser from the surface where it is installed. You should remove the bolts from the old condenser, remove the condenser, and install the new condenser. You must ensure that the condenser is bolted to the concrete slab that has been provided, and check the hoses that were attached to the old condenser.

You should turn off the circuit breaker for the AC unit, and you should remove the wiring carefully. You can set the wiring aside, and you may want to replace it if it is frayed or damaged. You might want to cover the wire tips if you believe they could be damaged while you are working.

When you remove the hoses from the old condenser, you should also label these hoses. The hoses are all slightly different, and they could be confused when you install the condenser. This is a simple way for you to prevent any problems.

2. Check The Hoses

As described in JNJ Air Conditioning website, You need to check the hoses in the house to ensure that they are not damaged. When you have long hoses, you may have kinks that need to be repaired, or you might need to replace the hoses. You should also ensure that the hoses are connected to the furnace properly. The hoses might leak while the device is running, and that is why you should look over the hoses while the AC is running.

3. Check The Coils

You need to check the coils on your condenser to ensure that they are holding the refrigerant. If the coils are leaking, you need to replace them before continuing. You cannot recharge the refrigerant on your own, and you should work with a professional who will help you with these small issues.

4. Check The Furnace

You should check the furnace to ensure that it is connected to the condenser properly. The furnace has a light on the front that will flash if you have issues with the furnace or the connection. You can check the owner’s manual for the flashing light patterns. You can repair any problems that arise, and you can continue with the installation. The air conditioner might cause problems if the hoses are not connected properly. If the condenser is not giving you the right amount of cooling power, you might get an alert signal.

5. Check The Blower

The blower that is connected to the furnace should be checked to ensure that it is blowing properly. If the blades are damaged, you should replace them as soon as possible. The blower fan should have a clean casing that is not dented, and you should ensure that it does not make bad noises when you turn it on. You can test the blower by flipping the fan switch on your thermostat.

The blower can be replaced easily, and it should be wired properly. Turn off the circuit breakers to ensure you are safe while wiring the blower, and replace the air filters.

6. Replace The Thermostat

You should replace the thermostat so that you have something that is easy to use. The thermostat should have a program that helps you save energy, and the thermostat should connect to the wall circuits properly. If the thermostat is in bad condition, it might not initiate the AC properly. You may think that you completed the installation incorrectly, but you did not.

7. Wire Everything

You can go back to wire the condenser to the power supply. You can turn on the circuit breakers to ensure that the AC unit has power, and you should go back outside to ensure that the wires are not sparking. When you are wiring everything, you need to make sure that you have not yanked the cables or torn them. You should check the wires once again to ensure that you do not have any damage. You may either remove the wiring, repair the wiring, or replace the wiring ends with something nicer. in some cases, you may need to purchase a special plug that will hook up to the condenser.

8. Test The System

The air conditioning system for your home should be tested before you assume that it works properly. Turn on the circuit breakers, turn on the fan, and listen for the blower. You also need to hold your hand in front of a vent to ensure that the air is cold. If the air is not cold, you must check your connections with the condenser. If the air is not blowing, you should check the blower. If the system does not start at all, you should check the wiring.

You might turn the system on without the filters, and you can add the air filter when you know that the blower works. This is the simplest way for you to ensure that everything works, and you must consider testing the system once a month to find any other problems that might arise.


The best part of doing a DIY air conditioning installation is that you can save money. You will not pay for labor charges, and you will learn a lot about your house in the process. Use these steps to install your AC, test your AC, and repair any problems that might arise.
