Air conditioning installation is a complex process. A good team will explain what goes on, answer your questions, and make sure you understand how to use your new system.
Your home cooling system consists of an outdoor unit for the compressor and an indoor evaporator coil. The refrigerant line set runs between these two units.
Before beginning air conditioning installation, the lead installer should inspect the site. During this visit, they should note any job details that may have been overlooked during initial consultations. They will also determine whether or not they need to bring any specialized equipment to your home. This will prevent them from having to return to their truck or shop, saving you both time and money.
The old air conditioner must be removed first. Then, the area around it should be cleared. It may be necessary to remove plants, stones, or other objects. The ground may have sunk or become uneven, and a new pad will have to be set up in order for the new unit to sit in the right spot. Moving an AC can cause severe damage, as the internal components are delicate and pressurized.
After the new outdoor pad is set, the technicians will install the new condenser. Afterward, they will connect the copper line set to the service valve, using a service rod and filler rod to ensure a leak-free connection. Then they will test the system, adding refrigerant as needed.
During this time, the technician will check and replace your thermostat (if needed). Typically, the new system will come with its own thermostat, so you won’t have to worry about buying one separately.
The indoor evaporator coil will then be installed. This might be in a closet or in the attic, depending on your home’s design. The installer will then re-connect the electrical wiring and add a filter dryer, which will protect the refrigerant lines from water and moisture.
Finally, the technicians will test and commission the system by switching it on and confirming that it is cooling. They will then clean up the work area and load the old equipment onto their truck.
It’s important to remember that any individuals handling refrigerant must have an EPA certification. This includes both the installation team and any subsequent service teams, as refrigerant is highly toxic. A reputable installation company will ensure that all workers meet these requirements before hiring them.
Equipment
Air conditioning isn’t just a luxury, it’s an essential part of life for people who live in warm climates. Air conditioning installation is a task that requires the right equipment and trained professionals. A qualified HVAC contractor will know how to safely install and operate an air conditioner, even if there’s no ductwork.
Tools needed for AC unit installation vary by unit type and window size. But most jobs require the same basic types of tools.
A hammer is one of the most common HVAC installer tools. You want a hammer that’s lightweight because you’ll be toting it around with all your other tools, but strong enough to get the job done.
Screwdrivers are another must-have tool for air conditioning installation. You’ll need to loosen and tighten screws throughout the process, so look for sturdy, reliable screwdrivers that can handle the work.
Another important tool to have is an electrical tester, also known as a multimeter. These devices test outlets and other electrical components to make sure they’re working properly. This helps prevent electric shock and other hazards.
Finally, you’ll need a PVC pipe and a service disconnect to connect your air conditioning system to the power grid. A service disconnect has specific locations where the high voltage circuit from the panel can be connected and a separate location for the whip that brings power to your air conditioner. The PVC pipe will take moisture produced by the air conditioner to a primary and secondary condensate drain, which should be placed at least 10 feet away from other equipment such as TV antennas, plants, telephone books, gypsum boards and more.
For window units, be sure to measure the width of your window before you purchase a portable air conditioner. You’ll also need to ensure that the window and frame can support the weight of the unit and that it’s securely fastened in place. Lastly, you’ll need to secure the unit to prevent it from blocking fire escape windows and other exits. Ensure that the unit is supported from underneath or by installing supporting metal brackets, interior angles and other hardware to ensure that it’s safe and stable.
Thermostat Installation
Installing a programmable thermostat is a great way to save on monthly heating and cooling bills. It typically takes less than an hour to complete the installation, and you can usually recoup the cost of the new device within just one season of use.
Before you start working on the thermostat, turn off power to the furnace and air conditioner at your breaker box. Then, remove the old faceplate and screws to expose the piping and wiring. Take a picture of the wiring configuration to help you identify which wires go where when reinstalling the new unit. If the wires are corroded or worn, clean them with a utility knife and scrape off any insulation. Label the wires with a piece of masking tape or write a letter on each one to indicate the terminal it connects to (e.g., blue wire to connection B).
Now you can begin connecting the wiring. Most low-voltage thermostat wiring is color-coded and labeled, so simply push down on a matching tab or screw to put the wire in place. After you finish connecting the wires, mount the thermostat and set your program according to the instructions provided with the device. If you’re using a smart thermostat, like the Cync Thermostat, you’ll also need to download the app and complete the setup process.
When installing a replacement thermostat, review the manufacturer’s instructions carefully to ensure it’s compatible with your system. Most replacement units will work with most systems, but there are exceptions. Make sure the thermostat you choose is compatible with your existing piping and circuits, and note any special requirements for operating your HVAC system (e.g., a C-wire). If you don’t have a dedicated C-wire terminal, you can add one by purchasing a C-Wire transformer or kit from your local home improvement store. Once the new thermostat is wired, activate power to your breaker box and return it to the “On” position. Then, connect the Wi-Fi to your thermostat and download the app to get started with your new system. Afterward, be sure to switch the power back on for the air conditioning at the breaker box and test your new thermostat.
Maintenance
An accredited maintenance provider will visit your home annually to clean and inspect the various components of the air conditioning system. This includes the filters, coils, and refrigerant levels. The technician will also make any necessary adjustments and repairs. Regularly scheduled maintenance can prevent costly breakdowns and extend the life of your air conditioner.
A properly maintained air conditioning system will operate at optimal efficiency, meaning it consumes less energy to maintain a comfortable indoor temperature. This results in reduced energy bills and reduced environmental impact.
During routine maintenance, technicians can spot minor issues before they escalate into major problems that require costly repairs or even system replacement. For example, a minor issue such as a refrigerant leak can become more serious over time if left unresolved. Air conditioning maintenance reduces the likelihood of this escalation, saving you money on repair costs and energy bills.
While an air conditioning system requires some time to adjust to your home’s environment and climate conditions, it can operate at peak performance once these changes have been made. An air conditioning maintenance appointment provides your equipment with the adjustment it needs to ensure it is operating at its most efficient and reducing pollutants in the indoor air.
After removing the old air conditioning unit from the window, the maintenance team will use a refrigerant recovery machine to remove any remaining refrigerant and drain it into a tank. The team will also disconnect electrical wiring and shut off the circuit breaker for the old air conditioner. They will then install a disconnect box, if the old unit did not have one.
A few days after the installation is complete, the maintenance team will return to perform a follow-up inspection. This will include testing the thermostat, making sure airflow is good, and answering any questions or concerns you may have.
Air conditioning maintenance appointments may seem like a minor inconvenience, but the benefits of regularly scheduled visits are far more significant. A well-functioning air conditioner is a safe and reliable way to keep your family cool throughout the summer, without risk of expensive damage or sudden breakdowns.
