The distribution of cold air throughout your house is accomplished by a central air conditioning system through the use of ductwork and registers, which are essentially apertures in the wall. The system, in its most basic form, works by drawing air in from the outside, cooling it, and then distributing it everywhere throughout the home through the ductwork.
There is a choice between split-system and packaged models for Air Conditioning Service Northern Beaches. A packaged unit is installed in a cabinet that may be placed either on the roof of your home or outside on your property, whereas a split system consists of an outdoor unit in addition to an interior cabinet. The packaged units are the ones that, with the addition of either electric heating coils or a gas furnace, are also able to perform the role of a heater.
If your property does not already have the necessary ductwork to accommodate your new system, you will need to consider making some alterations in order to retrofit an air conditioner into your home. On the other hand, if you replace an older unit with a more modern and energy-efficient one, you could observe a sizeable reduction in the amount of money you spend on your monthly energy bills.
The fact that units manufactured now consume up to half as much energy to run as those manufactured as recently as 10 years ago means that purchasing a new unit is an excellent investment for most homes. Obviously, picking the appropriate size of the system will also have an effect on you.

Professionally Installed Central AC Systems
Here’s more about having a professionally installed central AC system, including the pros and cons.
Perks to a Professionally Installed Central AC System
There are plenty of tasks that are well-suited for do-it-yourselfers, but there are other situations in which it is more prudent to bring in an expert to carry out the work. Here are a few advantages to having a trained HVAC technician install and service your new air conditioning unit rather than doing it yourself.
No Manual Labor for the Homeowner
When you do the work yourself, you could find yourself crawling beneath your house, moving large components, preparing an installation site, pouring concrete, climbing on the roof, or any one of a number of other physically demanding activities. If you hire a professional, you won’t have to do anything else but approve the job and pay the cost; everything else will be taken care of for you.
No Legwork Required
Many homeowners opt to employ a professional for the installation of a new air conditioning unit so that they are relieved of the responsibility of dealing with the administrative requirements of the installation. For many home renovation projects, including the replacement or installation of large-scale appliances like house heating and cooling systems, the local government in most areas requires homeowners to get permits before beginning the work.
Contractors and HVAC specialists have the ability to secure the necessary permissions on your behalf, which will make the process of meeting deadlines and getting things done more streamlined.
Professional Upkeep
Maintenance plans for HVAC systems are typically offered by professionals during the installation of new systems. If you hire a firm to install your new unit, they will already be familiar with it and will be able to return at the homeowner’s request to check in on things and make any necessary adjustments. Additionally, many installation packages include a specialized maintenance plan that is designed to assure the durability and security of your equipment.
Drawbacks of a Professionally Installed AC System
There are a few drawbacks to hiring out the AC installation job.
Increased Cost
Even if your contractor is able to negotiate a reduced price for your air conditioning unit due to the brand and manufacturer ties they have, you will still be responsible for paying the labor charges associated with having the unit installed. You may also be required to pay for the costs associated with the pre-installation work. This might involve building a concrete slab or making adjustments to your roof in order to accommodate the new assembly. Nevertheless, the expert installer will take care of all of the necessary elements for the process.
It’s Hard to Find a Reputable Company
When searching for a professional to install a new central air conditioning system in a home, homeowners who reside in more remote locations may have a harder time finding someone who is willing and able to drive to their location. The ability to have things delivered and installed is not one of the numerous benefits of living in a rural area, though.
DIY Central AC Systems
In this section, we will discuss the advantages and disadvantages of installing your central air conditioning system on your own. When instructing yourself on how to install central air conditioning on your own, it is essential to bear these considerations in mind.
Perks to a DIY AC Install
There are a number of advantages to carrying out a project on your own, and people who are wanting to tackle a DIY work should be aware of them. The top positive benefits of installing your new air conditioning unit by yourself are as follows:
Perk #1: Lower Costs
Although it is likely that the cost of the air conditioning unit will be higher if you buy it on your own (many businesses receive significant discounts from the manufacturers of air conditioning units if they buy directly from the brand), you will save money on the cost of installation if you handle the job on your own.
It is possible that the task will take you longer to accomplish; nevertheless, in terms of billable hours, there will be no additional costs incurred by you or anybody else.
Perk #2: Learning Something New
A lot of people who own their own homes love taking on home improvement projects because it forces them to become more knowledgeable about the tools, supplies, and techniques that are utilized. It makes perfect sense that you would want to install your own air conditioning system from the ground up if you want to do maintenance on it yourself.
In addition, acquiring those technical abilities will likely result in your being able to determine whether there is a problem with your system and, if there is, you will be able to resolve the issue on your own.
Perk #3: Consumer Choice
Homeowners who purchase and install their own air conditioning units have the most freedom and flexibility over the process, despite the fact that the majority of HVAC contractors would advise their customers to choose a certain brand or model of AC unit. You can still acquire the exact product that you won’t even if the local HVAC shop in your area does not sell the brand that you prefer, and you can accomplish this by doing the work on your own.
Drawbacks to a DIY AC Install
Here are the drawbacks to doing the air conditioning unit installation yourself:
Drawback #1: Paperwork Processes Take Time
It may be difficult to find your way through the permit system for a new air conditioning unit, particularly for homeowners who are not experienced with working on their own homes or the electrical systems within them. In most regions, permits are necessary not only for the units themselves but also for any housing or platforms that need to be installed in order to house them.
To find out what kinds of permissions you need, how much they cost, and what kinds of standards you have to meet, you will need to have a conversation with the people in charge of the county or city in your region.
Drawback #2: Length of the Job
When you work on a project by yourself, it might take a significantly longer amount of time than if an experienced team handle the intricacies of the project. If you are not experienced in the field of heating, ventilation, and air conditioning (HVAC), installing a new air conditioning unit may take you far longer than it would for a contractor and a crew to do the task.
In addition, you won’t be receiving payment for your work, which means that the amount of time you invest might end up costing you more than it would have if you had paid someone person to take care of it.
Drawback #3: Certification Requirements
To be able to take care of tasks related to air conditioning on your own, such as the removal of an older unit or the installation of a new one that requires more refrigerant, you will need to acquire a special certification. It is possible to obtain an EPA certification; but, in order to do so, you will need to prepare for a test, take the exam, and pay a price.
When purchasing more refrigerant for a new unit that may have been incorrectly charged, you are also required to have the same certification card.
Where to Find a Central Air Conditioning Unit
Going online is the most efficient way to identify a retailer from which to purchase central air conditioning equipment. However, due to the possibility of increased delivery charges, that is not always the best available choice. You may need to have some people on hand to help you unload the unit if the delivery company does not assist with that. Additional freight expenses may be required for some AC systems depending on where they are shipping from and to, and you may be required to pay those costs.
In addition to doing your shopping online, here are a few more options for purchasing a central air conditioning unit:
- Call or visit the heating and conditioning provider in your area. They may be able to assist you in locating and ordering a system (and maybe even arranging delivery) that is suited to both your requirements and your living space.
- Check with the hardware shop in your area for any items or recommendations they may have.
- Place your order through the neighborhood hardware or home improvement store. They may even put in a special order for the item that you require.
- Make some calls to the local contractors to get some recommendations. You may have access to a local supplier for air conditioning systems that you wouldn’t have any other way if you were a homeowner.
You will want to ensure that your device is in excellent working condition or that it is completely brand-new, regardless of where you locate it. It’s not illegal to look for a used air conditioner and put it in your home, but doing so exposes you to the possibility that the system won’t work properly or won’t be as energy-efficient as a brand-new one would be.
How to Install Central Air Conditioning Yourself
After you have ordered and received delivery of your brand-new air conditioning equipment, it is time to install it. At this stage, you need to choose where it will be installed, begin the process of putting it together, and add the refrigerant. The following are the stages that come next.
Where to Install the Unit
Obviously, you need to put your central air conditioning unit outside, and then you need to connect it to the ductwork within your house. When it comes to installing your new system, though, you have two options. Either a concrete pad may be poured to set the unit on, or the unit can be installed on the roof of the building.
No matter where you decide to put the system, the location must have sufficient airflow, be out of the way so as not to produce an excessive amount of noise, but still be accessible for maintenance, and let the unit be positioned and linked in the correct manner.
Ensuring an Energy-Efficient Install
It is essential to ensure that the ductwork that will support your new air conditioner is correctly sealed, even if your property already has existing ducting that will support your new air conditioner. After all, if cold air is escaping from the ducts, it means that less fresh air is entering your home. This will also result in greater energy expenses because you will need to cool the area below the house as well.
You also don’t want the ductwork to have any drooping or bends in it since any of those things might impair how well the system works. It may be necessary to access the crawl area beneath your house or even remove the flooring in order to check the ductwork and ensure that everything is linked appropriately.
Safety Considerations for a DIY Central Air Installation
If you already have an air conditioning unit that you wish to replace, there are several factors that are specific to your situation that you should take into account. Your previous unit should be drained of any residual refrigerant before you begin this process. In order to accomplish this, you are required to obtain a certification from the EPA in the handling of refrigerants, or you must locate someone who does have this qualification.
Naturally, if you buy a new unit that already contains refrigerant, you won’t have any need for additional refrigerant purchases. On the other hand, a unit that has been charged incorrectly may require more refrigerant, which may force you into a difficult situation just as you are ready to install it.
Because attempting to remove refrigerant without the appropriate expertise is risky, we do not advocate that any homeowner attempt to install or remove an air conditioner on their own. This is one of the tasks that fall under our purview.
Caring for Your AC Unit Over Time
Your brand-new air conditioning system will eventually require routine maintenance and maybe even some repairs. You should inspect the evaporator coil once a year (and clean it as needed), remove any debris that has accumulated in the system, and look for leaks in the refrigerant. Air filters should be cleaned or replaced on a regular basis.
Problems with the thermostat, drainage issues, clogged filters, and low or leaking refrigerant are some of the more typical concerns that can occur with air conditioning machines. Taking care of such concerns is outside the subject of this article; but, in many instances, engaging a professional may be both cost-effective and less stressful, especially if you do not have an understanding of HVAC systems yourself. This is especially true if you do not know how to do it yourself.
Connecting the AC System
The process of connecting the system requires situating the unit itself in the appropriate area and anchoring it in that spot, whether that be to a support structure on the rooftop or a pad on the ground level. Depending on the layout of the air conditioning unit, as well as whether or not you decide to replace the ducting or the thermostat, you may also need to install components inside the home.
In addition to that, you will need to:
Adjust the length of the refrigerant line so that it is optimal.
Check that the length of the drain plumbing is appropriate.
Make the connections between the electrical wires.
Put the thermostat in its place.
Eliminate any impurities from the lines that contain the refrigerant.
If the new air conditioning unit does not already have the refrigerant charged, you will need to do so.
Conduct some tests to make certain that everything is operating as it should.
Your new air conditioning unit will come with installation instructions as well as schematics that identify where and which components to connect. This guidance, however, is somewhat hazy for the majority of do-it-yourselfers and may be confusing to them. However, if you want to ensure that the installation goes according to plan, having some electrical and general HVAC expertise would be beneficial.
After Installing: Checking the System
You should be able to adjust the temperature on the thermostat and start the system once it has been installed. It is essential that the blower and the compressor are operating correctly in order to ensure that the air is being circulated through the ductwork and that it is of an appropriate temperature.
Even though it seems as though the unit is functioning normally, it is possible at any time for it to develop typical issues such as a leak in the refrigerant, improper maintenance, or a breakdown of the electronic control. To guarantee a long-lasting, energy-efficient, and safe installation of your home air conditioning unit, we strongly advise that you seek the assistance of a professional throughout the process of installing your new unit, or at the very least have someone verify your craftsmanship.
Now you know everything you need to know. You are now capable of installing your own central air conditioning system by yourself. Now that you’ve accomplished this, congratulate yourself, and get to work!
